Genetic infertility: New method can help men with too many sex chromosomes have babies – International Business Times UK

Scientists have developed a new approach to overcome a major cause of genetic infertility sex chromosome disorders. Tested in mice, it has led to the birth of healthy offspring from previously infertile animals.

Our sex is determined by our sex chromosomes. Girls typically have two X chromosomes (XX) while boys have one X and one Y (XY). However, some individuals are born with an extra sex chromosome which can be problematic if they decide to have children.

“Abnormalities of sex chromosomes are the most common genetic cause of infertility and include conditions such as Turners syndrome, where a female has only one X chromosome (XO) and Klinefelter syndrome where a male has an extra X chromosome (XXY),” Joyce Harper, Professor of Human Genetics and Embryology at University College London, who was not involved with the research, explained.

It is estimated that about 1 in 500 boys are born with an extra X or Y which can disrupt the production of mature sperm and render them infertile.

In a study now published in the journal Science, researchers have shown that it may be possible to remove the extra sex chromosome to produce fertile offspring. Indeed, reprogramming cells carrying a third sex chromosome led to the loss of the extra chromosome in mice as well as in human cells.

The team took fragments of ear tissue from XXY and XYY mice and cultured them. They were then able to collect fibroblasts – connective tissue cells. Reprogramming these cells into induced pluripotent stem cells (iPSC), they observed that some lost the extra sex chromosome.

Next, the scientists used a chemical signal to allow these stem cells to specialise into sperm cells. Finally, their injected these stem cells into mice testes, and the animals were able to produce fertile live offspring.

Preliminary experiments were also conducted with the cells of men with Klinefelter syndrome, showing that reprogramming them into stem cells also led to the loss of the extra sex chromosome.

The hope is that this approach will one day be used to treat infertile men with Klinefelter syndrome (XXY) or Double Y syndrome (though infertility is less common in this case) to have children through assisted reproduction.

But these are still the very early days, and a lot more research will have to be conducted in the lab before it can be used as a fertility treatment.

“Our most pressing challenge, which is not possible at present, will be to succeed in converting human stem cells into sperm in a dish. Even if we succeeded in doing this, there would still be the question of whether they work in assisted reproduction. There will be questions about the clinical application but also legal and ethical questions,” senior author James Turner, Group Leader at the Francis Crick Institute, told IBTimes UK.

Although the mice born with the technique were healthy, there are concerns for the human children that would be born as a result.

“The use of iPSC to produce sperm and children is not applicable safely in human clinical. At present, it appears to be dangerous. The transplantation of the reprogrammed cells would indeed expose the patients to develop tumours called teratomas, although we are working on the development of human in vitro spermatogenesis which would avoid transplanting reprogrammed sperm cells into the men,” Herv Lejeune from the department of reproductive medicine at Lyon’s University Hospital (France), who was not involved in the study, said.

What Drives Female Athletes? Chromatography Investigates – Chromatography Today

The difference in sporting performance between elite men and women is clear to see in the times recorded in running events and the distances thrown in field events. Though both male and female records improve the differences between the times and distances stays reasonably constant, with a mean difference of around 10 percent across athletics events between the genders.

The differences are basically down to how man and women are built physiologically we are different. Genetics and hormones mean that generally, men can out run and jump women due to innate characteristics. But these differences are reduced when power is not the main factor and in some sports, the greater flexibility of the female body can be an advantage.

The hormone testosterone is thought to be responsible for many of the differences in athletic performance when power is needed. Testosterone is the male sex hormone and is secreted from the testicles of men and the ovaries of women. As well as promoting male sexual characteristics, it is responsible for the increased muscle and bone mass in men, and lower fat levels seen in men when compared to women. Generally, the levels of testosterone in males is around eight times higher than in females.

But while it is recognised that testosterone an androgen or male hormone is the main cause of increased athletic performance in male athletes, there has been little research to back the claim up. The lack of concrete data has caused problems for athletics when the issue of hyperandrogenism has been levelled as a cause for banning some female athletes from competing.

Doping with androgens in womens sport is also an issue. Of the almost 300 elite athletes who were serving bans at the end of 2016, 116 were women and 64 of those were for androgen abuse. But some women suffer from hyperandrogenism naturally, and previously athletes who suffer from hyperandrogenism have been banned from competing unless they reduce their hormone levels.

Research published in the British Journal of Sports Medicine has addressed some of the issues of how testosterone affects sporting performance. The researchers compared over 2000 performances from the 2011 and 2013 World Athletic Championships with the androgen measurement in the athletes blood. Liquid chromatography was used to measure the androgen levels in serum, a technique discussed in the article, Accelerated Development of Quantitative Assays for Antibody Drug Conjugates.

They found that there was a correlation between testosterone levels and female performance. Hammer throwers, hurdlers and 400m runners had most benefit from high testosterone levels. The researchers suggest caution though, as the research doesnt provide causation. Higher testosterone levels give a leaner body mass, increased aggression and improved red blood cell production all factors that could be the driver behind better performance.

The laws of attraction: Pheromones don’t lie, fruit fly research suggests – Phys.Org

Female fruit flies’ pheremones reveal how much her body has invested its energy in producing eggs, changing her attractiveness as a potential mate, new research shows. Credit: University of Michigan

Life as a fruit fly seems pretty simple: Hatch, grow, eat some fruit, find a mate, produce hundreds of tiny offspring and dieall in a month or so.

But that part about finding a mateor matescan get pretty complicated, it turns out. The process revolves around pheromones, chemicals the body releases that others can smell or sense.

Whether you’re a fruit fly or a human, pheromones affect how attractive someone finds you, and how likely you are to find a mate.

Now, for the first time, scientists have shown that a female fruit fly’s pheromone signals can actually tell males how much energy her body has invested in egg production versus in storing away energy for her own survival.

And it’s a signal that she can’t change in order to make herself more attractive.

The more energy she invests in eggs, the more attractive her body’s pheromones will be, and the more likely she is to mate, says Scott Pletcher, Ph.D., a professor of physiology at the University of Michigan.

What makes individuals attractive and why do we have the preferences that we do? These findings made in flies may tell us more about how other speciesincluding, perhaps, usproduce and use attractive traits as part of mate selection.

The key role of insulin signals

Pletcher and his postdoctoral fellow Tatiana Fedina, Ph.D., worked with researchers from Canada and the University of Washington on the new discovery, which is published in PLoS Genetics.

Although the pheromonal blend remains a mystery, the team did show that pheromones, attractiveness and mating prospects of females differed greatly depending on their body’s insulin signaling, which indicates how the body is using food for egg production or energy storage.

In other words, when a male fruit fly catches a whiff of especially alluring pheromones from a female, he’s actually sensing a signal that her ovaries are producing plenty of eggs for him to fertilize. And that makes her more attractive as a potential mate.

Of course, the males have to be able to detect these signals at all. They also have to know how to tell the more egg-focused females from those whose pheromones indicate less egg production.

The researchers had previously shown that males were capable of making this distinction, and that those males that were the most attuned to females’ pheromones signals were more likely to reproduce.

“This adds to the growing evidence that natural selection has led to perceptive systems that are highly tuned to evaluate aspects of individual fitness,” says Fedina.

From insects to us

Researchers study fruit flies because it’s easy to change their DNA or signaling pathways and see what happens to, for instance, their mating patterns.

And, researchers say, because insulin signaling is the same across most animal speciesincluding humans, new findings may have implications for our understanding of mating and reproduction in many organisms.

“We show that even simple animals have evolved the capability of sensing molecular activities that determine reproduction and aging across many species. These cues may have evolved to influence attractiveness because they accurately predict mate fitness,” Pletcher says.

Taking pheromones out of the equation

Pletcher and his colleagues, including Zachary Harvanek, a student in U-M’s combined M.D./Ph.D. program, published another fruit fly paper earlier this year. They examined what happened when male fruit flies were altered so they couldn’t detect female pheromones, or when females around them did not give off pheromones.

These males lived longer and stored fat for their own survival better than those who could sense pheromones or were raised with pheromone-releasing females.

It was the perception of pheromones alonenot mating itselfthat cost the “normal” males the most, researchers found. But if they successfully mated, that energy cost was largely made up for by repairs to the system that the pheromones harmed, and the males lived longer than those who didn’t mate.

A ‘misguided’ theory

“For a long time, evolutionary biologists and public health officials have wondered why individuals and species that reproduce a lot live shorter lives, and the relationship was thought to be necessarily based on energy, in terms of the amount of food that can go to yourself or to making babies,” says Pletcher. “But our research is suggesting that the supposed link between reproduction and aging is misguided, and that aging may have to do more with expecting a lot of mating but not getting it.”

He adds that no mechanism has ever been found in humans for the supposed life-shortening effect of having large numbers of children. The idea that giving energy to an offspring through pregnancy takes away energy needed for a long life needs revisiting, he suggests, because it’s likely simplistic and outdated.

“In the fruit flies, the neural circuits that drive aging are different from the ones that drive reproduction, and those circuits are present in our own brains too,” he says. “We should be looking at these circuits more closely to see what they’re influencing, including cues that may be influencing our social evaluations of one another but that we don’t understand yet. We need to see if there’s a single underlying cause for many forms of attractiveness cues.”

Men, Listen Up: Women Like The Smell Of Guys Who Eat A Certain Diet – NPR

Your diet can influence your appearance. You knew that. But did you know that what you eat can also affect your body odor and your attractiveness to the opposite sex? Lilli Carr for NPR hide caption

Your diet can influence your appearance. You knew that. But did you know that what you eat can also affect your body odor and your attractiveness to the opposite sex?

What we eat can influence more than our waistlines. It turns out, our diets also help determine what we smell like.

A recent study found that women preferred the body odor of men who ate a lot of fruits and vegetables, whereas men who ate a lot of refined carbohydrates (think bread, pasta) gave off a smell that was less appealing.

Skeptical? At first, I was, too. I thought this line of inquiry must have been dreamed up by the produce industry. (Makes a good marketing campaign, right?)

But it’s legit. “We’ve known for a while that odor is an important component of attractiveness, especially for women,” says Ian Stephen of Macquarie University in Australia. He studies evolution, genetics and psychology and is an author of the study.

From an evolutionary perspective, scientists say our sweat can help signal our health status and could possibly play a role in helping to attract a mate.

How did scientists evaluate the link between diet and the attractiveness of body odor?

They began by recruiting a bunch of healthy, young men. They assessed the men’s skin using an instrument called a spectrophotometer. When people eat a lot of colorful veggies, their skin takes on the hue of carotenoids, the plant pigments that are responsible for bright red, yellow and orange foods.

“The carotenoids get deposited in our skin,” explains Stephen. The spectrophotometer “flashes a light onto your skin and measures the color reflected back,” says Stephen. The results are “a good indicator of how much fruits and vegetables we’re eating,” he says.

Stephen and his colleagues also had the men in the study complete food frequency questionnaires so they could determine the men’s overall patterns of eating. Then the men were given clean T-shirts and asked to do some exercise.

Afterward, women in the study were asked to sniff the sweat. (Note: The methodology was much more scientific and precise than my breezy explanation, but you get the picture.) “We asked the women to rate how much they liked it, how floral, how fruity,” and a bunch of other descriptors, explains Stephen.

It’s a small study, but the results were pretty consistent. “Women basically found that men who ate more vegetables smelled nicer,” Stephen told us.

Men who ate a lot of meat did not produce a sweat that was any more or less attractive to women. But meat did tend to make men’s odor more intense.

“This is not the first study to show that diet influences body odor,” says George Preti, an adjunct professor in the dermatology department at the University of Pennsylvania and a member of the Monell Chemical Senses Center in Philadelphia.

A study published in 2006 found that women preferred the odor of men who ate a non-meat diet, “characterized by increased intakes of eggs, cheese, soy, fruit and vegetables.”

But Preti points out that the relationship between diet and body odor is indirect.

Some people think if they eat a garlic or onion or a piece of meat they will smell like that food. “But that’s not what happens,” Preti says. Your breath might smell like the food you eat, but not your sweat.

Body odor is created when the bacteria on our skin metabolize the compounds that come out of our sweat glands.

“The sweat doesn’t come out smelly,” Preti explains. “It must be metabolized by the bacteria that live on the surface of the skin.”

Now, of course, at a time when good hygiene and deodorant use are commonplace, is the smell of our sweat a big concern?

I put that question to the happy hour crowd at a bar down the street from the NPR headquarters in Washington, D.C.

“I’m pretty OK with my smell,” Stefan Ruffini told me. That evening he was ordering a burger on a bun and a side of fries, along with a beer. When I told him about the findings of the study, he laughed it off.

“I’ve got a girlfriend, so I don’t worry about these things,” he said.

The study did not assess diet and odor attractiveness among same-sex couples.

“As a lesbian, I haven’t smelled a man in several years,” Stacy Carroll, who was also at happy hour, told me. “I eat a lot of produce, I have a girlfriend, so it’s working out.”

Carroll says people who eat a lot of fruits and vegetables are more likely to be interested in their health “feeling good, looking fit” than their smell.

When mama’s not happy, nobody’s happy – The Capital Journal

Nurture versus nature is a question often bandied about. Is it the environment in which the child is raised, or is it the genetics provided by the biological parents, that most influences what kind of person a child will grow to be?

We have known for a long time that if a parent is depressed, their children are at higher risk for having anxiety, depression, and disruptive behavior. Indeed, the offspring of depressed parents have up to a three-times higher risk of these problems when compared to the children of parents who are not depressed. So, is it because of the environment; or is it genetics?

Research published in the Journal of the American Medical Association brings us closer to an answer. It is important to note that the study consisted primarily of mothers with depression, as they are far more likely to report symptoms and come in for treatment than fathers with depression. However, researchers believe that their discovery applies to whichever parent has depression, regardless of whether they are male or female. The results were fascinating: effective treatment of the mother lead to resolution of psychiatric problems in the child.

Study author Myrna Weissman, professor of psychiatry and epidemiology at Columbia University, said while depression may be a genetic disorder, [this study showed that] a parents illness has a very strong environmental

effect on her child. In other words, when mamas not happy, nobodys happy. Weissman also pointed out if you have a depressed mother, you ought to do everything you can to get her better, because theres a double effect that will impact their children.

I think the message from this research is very powerful, and should be taken to heart by any mother or father. If you as a parent are having psychological trouble, get help and your child will be better for it. If you wont do it for yourself, do it for your kids.”

Friday Night Inc. Announces Dr. Torres Advisor and Genetics Update – Yahoo News

VANCOUVER, BC / ACCESSWIRE / August 11, 2017 / Friday Night Inc. (Friday Night) (CSE:TGIF) (1QF.F) (OTC PINK: VPGDF) is pleased to announce that the Company has appointed Dr. Anthony R. Torres, MD to its board of advisors and would also like to provide an update on the genetics breeding program at the Company’s 91% owned subsidiary, Alternative Medicine Association, LC. (AMA).

NEW GENETIC STRAIN

Over the past several months, AMA has been cross breeding existing strains in hopes of creating an improved cannabis product. This time consuming and laborious process has resulted in a new product offering that only AMA will be able to provide.

One of AMA’s favorite prototype plants from the genetics program is a strain they have created and named ”Naughty Cookies”. Over the last year and thousands of test plants later, AMA created the new strain by crossing the high-THC and popular ‘Girl Scout Cookies’ strain with the high-yielding ‘Juggernaut’ male. The buds are very frosty, aesthetically pleasing and dense with light purple coloration.

This week AMA received the test results for the first lot. The cannabinoid content was higher than any strain AMA had seen in the last 3 years, and the THC content came back as 34.9%. Most fortunately, AMA had the foresight to cultivate over 70 of these plants in anticipation of great results. These will be flowered during the next growing cycle and so far are yielding over 2 pounds per light of dried flower.

The creator of this strain and Director of Operations, Mr. Ben Horner said, ”This gives us a competitive edge in a market which we now control. When new cultivators come on board, we will be the only producer with this strain. I feel it will inevitably become a favorite in Las Vegas.”

NEW ADVISOR TO THE COMPANY

Anthony R. Torres, M.D. with training at the National Institutes of Health, Yale University School of Medicine and the University of Utah, has considerable experience in the separation sciences of biological molecules. Anthony is widely published and has made a career not only in university research, but also in the biotechnology field including protein enrichment and advance separation processes. He is an inventor and owns several patents in the field. He is not new to the world of start-up companies and continues to be a pioneer in biotechnology. He also brings a deep understanding of the cannabis plant and its molecular structure.

Dr. Torres commented, ”I am very interested in applying traditional laboratory processes to the rapidly developing field of molecular cannabis. I believe that there are many positive applications for the natural benefits of this plant in modern medicine and that it has the potential to help hundreds of thousands, perhaps even millions of people.”

Let’s talk about male infertility – Toronto Star

(Infertility) can be a very painful thing for a lot of people and it was for us, Herbert says. But our pain was short-lived . We were very lucky.

Thats because couples can go through numerous IVF cycles and never have a baby.

The meta-analysis didnt examine the cause for the decline, but the authors say the fact that its occurring in the West suggests chemicals used in commercial products play a role. They warn the decline has implications beyond fertility and reproduction, saying it may be a canary in the coal mine for male health across the lifespan.

In the industrialized world were seeing a very definite and clear decline in sperm counts, in quality, even among fertile men, and as the world becomes more toxic, the effect will be greater, says Dr. Art Leader of The Ottawa Fertility Centre and a board member of Conceivable Dreams, an Ontario-based infertility patient advocacy group.

I think as well as The Handmaids Tale were going to have a sequel to it called The Manservants Tale.

Although men cant change the burden of global pollution there are things they can do to optimize fertility, says the professor of Obstetrics, Gynecology and Reproductive Medicine at the University of Ottawa.

He suggests minimizing alcohol, smoking and exposure to smoke, increasing exercise, maintaining a healthy weight, eating organic foods, taking an adequate dose of Vitamin D and not using anabolic steroids. And be mindful of endocrine disruptors, which are chemicals found in everyday products that interfere with the bodys naturally occurring hormones. Examples include bisphenol A (BPA), dioxins, phthalates and fire retardants.

Even medications used by men to stop hair loss finasteride and minoxidil have been shown to lower sperm counts. But once men stop taking these drugs, sperm counts bounce back.

Men should also be wary of reproductive hazards on the job, says Leader. For instance, bakers and chefs who work in hot places; mechanics and industrial workers who handle the metal degreaser Trichloroethylene (TCE), and farmers who work with herbicides and pesticides may be at risk.

If someone is really concerned, they can freeze their sperm before age 40, says Leader, noting: Men have a best-before date of 40.

For Herbert, learning in 2014 that he had a low sperm count was a difficult blow. The normal range is 15 million to 200 million sperm per millilitre of semen he had about one million.

But infertility wasnt something he felt comfortable talking about with his buddies.

There is a taboo attached, he says. Whats the stigma? That youre shooting blanks. It just doesnt feel manly. This is the one thing that should be easy for us to do.

We go through so much of our life trying not to get somebody pregnant … And then you get to this stage and its like, What? I need help? Its not working? I dont have enough?

In hindsight, Herbert says, it would have been a lot more helpful for me to talk about it. But he didnt, except with his wife, who happens to be a psychotherapist.

Jan Silverman, a fertility counsellor who also works at Create Fertility Centre in Toronto, says men dont easily open up about infertility. But when given the chance they will.

We get all kinds of guys coming out with sperm issues, says Silverman, who runs an infertility support group. Wives will say Oh, hell never talk. And you get them in the room, with a couple of other guys there, and before you know it they are talking.

Often what surfaces are feelings of shame, embarrassment and sexual inadequacy. And theres guilt because even though theyre infertile, its their female partners who undergo the invasive and uncomfortable fertility treatments.Ill never forget having this huge police officer a six-foot-five, big, burly guy who found he had a sperm count of zero. He sat in my office weeping, asking Me?

That was so poignant and telling because you never know. Thats the interesting thing about sperm. Just because you ejaculate you dont know whats in there. So for men, there is such a sense of shock.

Even popular culture is tackling the topic. Recently on the HBO hit Ballers, the main character Spencer Strasmore, a retired football player portrayed by Dwayne The Rock Johnson, is worried he may not have swimmers and seeks a referral to a fertility specialist. Its still unclear how that storyline will unfold because moments before he goes into a collection room to ejaculate, he gets called away for work.

Dr. Keith Jarvi, director of the Murray Koffler Urologic Wellness Centre and Head of Urology at the Mount Sinai Hospital, says a sperm test should be the first thing a couple undergoes as part of fertility testing.

Its not any statement about your manhood, says Jarvi, who heads the biggest centre in Canada for male infertility. The frequency with having a lower sperm count is not uncommon.

The test checks to see if there is sperm, how much of it there is, how it moves and if it appears healthy and normal. The test is covered by OHIP, relatively easy to do and may spare the female partner from undergoing treatments.

Guys are often ignored, says Jarvi. But if you ignore the guy you might not find a fertility problem that could be fixed.

Sometimes the fix is simple. Avoiding regular exposure to heat, such as hot baths and saunas, wearing looser underwear and keeping the genital area cool have all been shown to help.

Theres a whole series of new techniques and new treatments that we can now offer men that we couldnt offer them 15 years ago, he says. Were now taking on more and more patients who we thought before had no hope.

For the Herberts, fertility doctors suggested a type of IVF called Intracytoplasmic Sperm Injection, which is commonly used to treat severe male factor infertility. Its a laboratory process involving eggs extracted from the female, and semen retrieved from the man. An embryologist takes a single healthy sperm and injects it into the egg to create an embryo that is then transferred to the uterus.

Herbert and his wife also made lifestyle changes. He started taking vitamins, improved his diet, stopped doing hot yoga, started acupuncture and eliminated soaps, shampoos, deodorants, toothpaste and household products with potentially harmful chemicals.

In total, they spent about $30,000 during that first IVF attempt.

Once we said, Were going for this, then we were all in, says Herbert.

But it wasnt enough. In November 2015 they were devastated to learn that first cycle of IVF didnt work. They tried again in 2016. By then the Ontario Fertility Program was up and running and they were eligible for provincial funding, which cut their costs by half. The procedure is covered, but not the drugs. Conceivable Dreams, where Herbert is a member, is trying to persuade insurance companies to add the drug cost to their standard plans.

About 8,200 patients have received government funded IVF treatments since it was introduced in December 2015, says the health ministry. There is a database tracking how many funded IVF cycles are the result of male infertility, but the figures are not yet available.

Doctors warned that IVF was a crap shoot, but the Herberts hit the jackpot on their second attempt.

If it had been unsuccessful, I wouldve spent the rest of my life having to carry that: We spent our lives childless because of me. Thats pretty intense.

But then Ori came along. Herbert now looks forward to a life filled with discovering the joys of fatherhood: Playing with her, teaching her to walk, speaking with her.

Shes like a book that Im anxious to read.

A Google employee was fired after blaming biology for tech’s gender gap but the science shows he’s wrong – Yahoo Finance

A Google engineer has been fired after writing a memo asserting that biological differences between men and women are responsible for the tech industrys gender gap.

We need to stop assuming that gender gaps imply sexism, James Damore wrote in the manifesto, which was first reported by Vices Motherboard and later released in full by Gizmodo.

The 10-page document criticizesGoogle initiatives aimed at increasing gender and racial diversity, and argues that Google should focus more on “ideological diversity” to make conservatives more comfortable in the companys work environment.

In response, Google CEO Sundar Pichai cut his vacation short and wrote a memo criticizing Damores manifesto for advancing harmful gender stereotypes. “To suggest a group of our colleagues have traits that make them less biologically suited to that work is offensive and not OK,” Pichai wrote.

Experts have been quick to cite numerous scientific meta-analyses of differences between the sexes, most of which suggest that men and women are alike in terms of personality and cognitive ability. Here are the specific claims Damore made in his manifesto, and the real science behind them.

Although some differences between men and women have been observed by scientists, they are mostly physical ones. Current research generally does not find evidence that variations in preferences, psychology, or personality stem from genetic or biological factors. Rather, theyre primarily attributed to culture and socialization.

In his manifesto, however, Damore suggested the gender differences he lists do have biological components. One justification he gives for this belief is that the differences he mentions are what we would predict from an evolutionary psychology perspective and are universal across human cultures.

However, a 2001 analysis of responses to a prominent personality inventory test found that contrary to predictions from evolutionary theory, the magnitude of gender differences varied across cultures a direct contradiction to his argument.

One of the main biological differences between men and women, according to Damore, is that women are more open to feelings and have a stronger interest in people rather than things.

He went on to suggest: These two differences in part explain why women relatively prefer jobs in social or artistic areas. More men may like coding because it requires systemizing.

Throughout his memo, Damore linked to many Wikipedia pages as justification for his claims but neither news media organizations nor scientists accept Wikipedia as a credible source of information, especially when used in policy recommendations.

To back up the people over things hypothesis, Damore cited a study published in the journal Social and Personality Psychology Compass in 2010; however, that work never suggests that the gender differences it lists have a proven biological basis.

In fact, the study says the opposite: Although most biologic scientists accept that sexual selection has led to sex differences in physical traits such as height, musculature, and fat distributions, many social scientists are skeptical about the role of sexual selection in generating psychological gender differences.

A 2000 review of at 10 studies related to gender differences in empathy also suggests men and women dont have innate differences in this area. The researchers found that such distinctions were only present in situations where the subjects were aware that they are being evaluated on an empathy-relevant dimension or in which empathy-relevant gender-role expectations or obligations are made salient. In other words, differences had to do with how people responded to expectations of them, not any inherent abilities.

Adam Grant, a professor at University of Pennsylvanias Wharton School, has also highlighted the fact that differences between men and womens professional preferences are not genetically determined.

The data on occupational interests do reveal strong male preferences for working with things and strong female preferences for working with people, Grant wrote in a LinkedIn essay responding to Damores claims. But they also reveal that men and women are equally interested in working with data.

In the memo, Damore suggested that women are biologically prone to express their extraversion as gregariousness instead of assertiveness, and to be more agreeable than men.

That difference, he claims, leads to women generally having a harder time negotiating salary, asking for raises, speaking up, and leading.

Again, Damore didnt cite any evidence for this part of his argument. A 2005 analysis of 46 meta-analyses of gender differences suggests its false.

According to the American Psychological Association, one experiment in that analysis involved participants who were told that they would not be identified as male or female. Under those conditions, none conformed to stereotypes about their sex when given the chance to be aggressive. The researchers found the opposite to be true, in fact: women were more aggressive and men were more passive, they wrote.

And a meta-analysis of leadership effectiveness published in 2014 suggests that when it comes to others evaluations of leaders (as opposed to the leaders own perception), women are rated as significantly more effective than men. When looking at self-ratings, however, men rate themselves as significantly more effective than women rate themselves.

That suggests that context and learned expectations are responsible for some observed gender disparities.

Damore also suggested that women are biologically prone to feel higher levels of stress and anxiety, and posited that difference might contribute to the lower number of women in high stress jobs.

The only source he gave for this information is Wikipedia. However, the misconception might have stemmed from analyses of the Revised NEO Personality inventory (the prominent personality test mentioned above).

On the test, according to a2001 secondary analysis, women reported themselves to be higher in neuroticism. But those responses are based purely on self-perception (which is heavily influenced by social and cultural factors) so itd be problematic to consider that a biological difference.

Women on average look for more work-life balance while men have a higher drive for status on average, Damore wrote.

As evidence for this, he cited a 2006 paper published in the British Journal of Guidance and Counseling.

That article highlights the fact that more women value a balance between their professional and home lives than men. It also suggests that men are more likely to make their careers their first priority. However, nowhere does that paper suggest that these preferences come from biological or evolutionary differences between the sexes.

In fact, it makes this caveat: They are differences of degree, with large overlaps between men and women. They are not fundamental qualitative differences, as often argued in the past in order to entirely exclude women from male occupations such as management, the military and the professions.

Damore does make a couple of valid points about the gender expectations of men, and the way these might contribute to the tech industrys gender gap.

He suggested that because men are often judged based on their status in the professional world, that pushes many men into these higher paying, less satisfying jobs for the status that they entail.

Furthermore, Damore noted that men are still very much tied to the male gender role, and wrote that allowing men to express traits or pursue goals that are traditionally thought of as feminine would help alleviate some of the gender-gap problems.

Although he doesnt cite any sources for these claims either, it seems logical that gender expectations and stereotypes are partially responsible for the types of roles men seek out in the workplace.

(Reuters/Beck Diefenbach) Pichai also acknowledged the validity of Damores complaints about perceived intolerance of conservative viewpoints among Googles employees.

There are co-workers who are questioning whether they can safely express their views in the workplace (especially those with a minority viewpoint), the CEO wrote in his statement. They too feel under threat, and that is also not OK.

Damores views, however, were not the reason he was fired rather, it was because portions of his manifesto violated Googles code of conduct.

According to Reuters, Damore is now pursuing legal action against Google, though labor law experts suggest his case could be an uphill battle.

Google has fired the engineer whose anti-diversity memo reflects a divided tech culture – Vox

Google has fired the employee who authored a controversial 10-page memo arguing for less emphasis on gender diversity in the workplace, reports Bloomberg. The document was first posted to an internal company forum on Friday, August 4, and immediately went viral among Google employees; it was then leaked to the media over the weekend, setting off a firestorm of outrage and debate while highlighting the companys ongoing struggles to meaningfully diversify its workforce.

Titled Googles Ideological Echo Chamber, the memo argues that the reason women are underrepresented in the tech industry has to do with “biological causes” between men and women. Its author, James Damore, was a senior software engineer at Google (a mid-level position at the company); Damore, who holds a doctorate in systems biology from Harvard and had worked at Google since 2013, has confirmed to multiple outlets that he was terminated for perpetuating gender stereotypes.

Damores memo specifically criticizes the company for its ongoing diversity and inclusion initiatives, which include encouraging its employees to take classes in unconscious bias. He uses primarily stereotyped misconceptions about men and women to argue that gender gaps [do not always] imply sexism, and declares that discriminating just to increase the representation of women in tech is misguided and biased as well as unfair, divisive, and bad for business.

Notably, the memo complicates an already unflattering moment for Google: The company has pledged to improve its recently updated internal diversity metrics which paint an unsympathetic picture of yet another tech company whose employees are predominantly white and male while also facing wage discrimination scrutiny from the US Department of Labor for systematically underpaying its female employees.

Reactions from Google employees and the public at large have been wide-ranging. Many people are utterly appalled, and have expressed outrage not only over the memos dangerous anti-diversity sentiments and faulty logic, but the fact that Damore felt confident posting such a screed to an internal forum for all of his colleagues to see. He even used his own name, which was quickly leaked to the press.

But Damores memo has also generated some support from both inside and outside the company and thus has kicked off a larger discussion about how far free speech should go in workplace environments. Its also highlighted Googles lack of gender parity and the tech industrys ongoing problems with fostering safe spaces for women.

In Damores memo, he states that women are more neurotic and have a lower stress tolerance than men, and that these characteristics not systemic harassment, routinely being passed over for promotions, or other well-documented instances of sexism in tech culture are the reason why women do not succeed as often as men do in the high-pressure industry.

He also argues that men have a higher drive for status than women, and suggests that this factor, rather than well-documented gender biases in the workplace, may be responsible for the lack of women in leadership positions both at Google and in the tech industry as a whole.

Finally, Damore calls for Google to De-empathize empathy, arguing that being emotionally unengaged [with the issue of diversity] helps us better reason about the facts. He decries political correctness, discounting the very concept of unconscious bias and arguing against unconscious bias training for Google employees.

Damore generally attempts to support his arguments by citing individual research papers about two pernicious approaches to classifying human ability: biological essentialism and biological determinism.

Biological essentialism is the belief that people of different genders, race, and sexual orientation are all innately, essentially different due to a set of nebulous predetermined biological factors. Along with all other kinds of essentialist thinking, the scientific establishment routinely warns against biological essentialism as fundamentally unscientific.

Biological essentialism the idea that men and women are programmed to desire certain things has been largely discredited, the Guardian noted last year. Tristan Bridges, a sociology professor at the College at Brockport State University of New York, told the Guardian that this is because [biological essentialism] relies on stereotypes of early humans, and the adaptive problems they faced that are historically inaccurate and fail to account for much of what we know about how early humans lived.

Instead, many scientists agree that stereotypes about how men and women are supposed to act, reinforced by social structures, is a major factor in how people act. Through a rather constructivist approach most studies show that no scientific experiment has proved the existence of systematic and/or significant biological sex differences in most cognitive functions, notes a 2010 Stanford research paper examining stereotypes and gender identity.

Biological determinism is the belief that hereditary genetics determine most factors about individuals. This belief led to the appalling eugenics experiments of the early 20th century, and in the decades since it has been thoroughly debunked by the mainstream scientific establishment.

Scientists have been issuing warnings for nearly two decades that biological essentialism and determinism, with their implied justifications for racism and homophobia, are creeping back into scientific theory. The limitations of womens brains are on the front line in this battle of ideas, wrote a team of researchers in 2005, in response to a piece of gender essentialism which argued that the male brain is the systematizing brain, while the females is the empathizing brain.

Writing for the Guardian in response to Damores memo, Angela Saini, the author of Inferior: How Science Got Women Wrong, offered a good summary of why this view of gender is fundamentally flawed. She notes that at this point in the development of neuropsychology, its well-established that differences in individual neurology have virtually nothing to do with gender.

There isnt a neuroscientist alive who can say with confidence which sex any given brain belongs to, she writes. She also explains that Damores use of individual scientific articles to support his arguments is misguided, because science as a whole relies on scientific consensus rather than individual findings in individual papers and scientific consensus does not support Damores biological essentialism or determinism.

Instead, longstanding scientific consensus holds that the way humans develop is fundamentally more complicated than a simple matter of nature versus nurture. But people who believe in essentialism and determinism frequently challenge this view, often in an attempt to lend scientific credence to bigoted belief systems.

Unsurprisingly, the memo has been met with plenty of anger and concern. Many people whove discussed it publicly or in conversations that have since been leaked to the press seem to agree that its arguments are faulty and dangerous. Furthermore, many Google employees find it particularly troubling that Damore felt empowered to widely share such harmful views of gender on the companys internal employee forum.

One engineer reportedly wrote that the memo had caused irreparable harm to 1000s of Googlers, and that going forward, I cannot and I will not work with James Damore. He went on to detail the ways in which he would not engage with or interact with Damore, his code, or his product development.

On Saturday, Danielle Brown, Google’s recently appointed vice president of diversity, responded to Damores memo and the backlash it generated via an internal memo to employees. Brown unequivocally dismissed Damores arguments, noting, Like many of you, I found that it advanced incorrect assumptions about gender. I’m not going to link to it here as it’s not a viewpoint that I or this company endorses, promotes or encourages.

Declaring that Google is unequivocal in our belief that diversity and inclusion are critical to our success as a company,” she went on to assert that all employees with alternative views, including different political views, [should] feel safe sharing their opinions. But, she added, that discourse needs to work alongside the principles of equal employment found in our Code of Conduct, policies, and anti-discrimination laws.

When contacted by email, a Google spokesperson also shared a response to Damores memo written by Ari Balogh, Googles VP of engineering:

Id like to respond to the “pc-considered-harmful” post. Questioning our assumptions and sharing different perspectives is an important part of our culture, and we want to continue fostering an environment where its safe to engage in challenging conversations in a thoughtful way. But, in the process of doing that, we cannot allow stereotyping and harmful assumptions to play any part. One of the aspects of the post that troubled me deeply was the bias inherent in suggesting that most women, or men, feel or act a certain way. That is stereotyping, and it is harmful.

Building an open, inclusive environment is core to who we are, and the right thing to do. Nuff said.

But neither Browns nor Baloghs responses did much to allay the outrage and concerns shared by many of Damores fellow Google employees. There are certain alternative views, including different political views, which I do not want people to feel safe to share here, one engineering manager reportedly wrote in response to Browns memo. Several employees openly questioned whether Damore would be fired. One employee reportedly wrote that if Googles human resources department did not discipline Damore, she would seriously consider leaving the company.

On Monday, Google CEO Sundar Pichai sent an email titled Our words matter to Google staff noting that while the company strongly support[s] the right of Googlers to express themselves, and much of what was in that memo is fair to debate, Damores memo had violated parts of the companys Code of Conduct and cross[ed] the line by advancing harmful gender stereotypes in our workplace.

Pichai continued:

To suggest a group of our colleagues have traits that make them less biologically suited to that work is offensive and not OK. … The memo has clearly impacted our co-workers, some of whom are hurting and feel judged based on their gender. Our co-workers shouldnt have to worry that each time they open their mouths to speak in a meeting, they have to prove that they are not like the memo states, being agreeable rather than assertive, showing a lower stress tolerance, or being neurotic.

At the same time, there are co-workers who are questioning whether they can safely express their views in the workplace (especially those with a minority viewpoint). They too feel under threat, and that is also not OK. People must feel free to express dissent. So to be clear again, many points raised in the memo such as the portions criticizing Googles trainings, questioning the role of ideology in the workplace, and debating whether programs for women and underserved groups are sufficiently open to all are important topics. The author had a right to express their views on those topics we encourage an environment in which people can do this and it remains our policy to not take action against anyone for prompting these discussions.

The past few days have been very difficult for many at the company, and we need to find a way to debate issues on which we might disagree while doing so in line with our Code of Conduct.

After Damores memo was made public, many people echoed the appalled feelings of Google employees whod spoken out against it. The faulty logic behind the memo dominated the discussion, as did explanations of why Damores decision to post it was so inherently damaging.

In a lengthy open letter to Damore, Yonatan Zunger, a former Google employee who only recently left the company, shared his views from the perspective of having been a distinguished engineer an extremely high-level position at Google. Zunger noted that, despite speaking very authoritatively, Damore does not appear to understand gender, engineering, or the consequences of what he wrote, either for others or himself.

Zunger, who wrote as is if he were still working at Google and had been tasked with handling the situation internally, addressed Damore directly to explain not only why the beliefs outlined in his memo are so dangerous, but why writing and posting the memo was such a terrible judgment call:

What you just did was incredibly stupid and harmful. You just put out a manifesto inside the company arguing that some large fraction of your colleagues are at root not good enough to do their jobs, and that theyre only being kept in their jobs because of some political ideas. And worse than simply thinking these things or saying them in private, youve said them in a way thats tried to legitimize this kind of thing across the company, causing other people to get up and say wait, is that right?

I need to be very clear here: not only was nearly everything you said in that document wrong, the fact that you did that has caused significant harm to people across this company, and to the companys entire ability to function….

And as for its impact on you: Do you understand that at this point, I could not in good conscience assign anyone to work with you? I certainly couldnt assign any women to deal with this, a good number of the people you might have to work with may simply punch you in the face, and even if there were a group of like-minded individuals I could put you with, nobody would be able to collaborate with them. You have just created a textbook hostile workplace environment.

But not everyone was unified in their opposition to Damores memo. A set of informal polls that reportedly circulated internally among Google employees and were subsequently leaked online show a more divided set of reactions, ranging from strong agreement with its position to strong disapproval:

Its important to note that, as indicated in images above, fewer than 300 of the Googles thousands of employees responded. But the results do hint at deeper underlying ideological differences at Google, and suggest that at least some of the companys employees agree with Damores claims that his views are seen as anathema to a productive workplace and thus should be shamed into silence.

Both inside and outside Google, Damores memo has garnered him open supporters, with one blogger calling him the only set of balls left at Google. Meanwhile, Motherboard spoke to an anonymous Google employee who described the reaction among his fellow employees as a mix of women saying, This is terrible and its been distracting me from my work and it shouldnt be allowed; Men and women saying this is horrible but we need to let him have a voice; and men saying This is so brave, I agree.

The ensuing debate over his memo and subsequent firing has inevitably touched on issues of free speech and whether any workplace should allow such harmful ideas to safely be voiced. And one overarching theme of that debate has been the argument that free speech cannot and should not be an excuse for employees to spread and legitimize harmful ways of thinking or encourage the dehumanization of other people especially when the dehumanizing arguments are linked to bad science.

Had Google been willing to tolerate the posting of the memo in the spirit of supporting free speech, such tolerance would undoubtedly have been a deal breaker for many of the companys employees who were unsettled by the notion that it could embolden more of their co-workers to advocate for sexist or racist views.

Its no secret that Google (to say nothing of the tech industry at large) has a diversity problem. The companys most recent workforce representation data revealed that, despite its various ongoing diversity initiatives, 69 percent of the companys total workforce is male, while 56 percent is white. (At many other leading technology companies, these numbers are far worse.) In turn, Google acknowledged that, While weve made progress in recent years for both women and people of color, there are areas for improvement across the board and insisted that it is actively working to hire more women engineers and people of color.

In her weekend memo to employees, Brown argued that Damores memo is an unfortunate reaction to Googles progressively changing culture. Strong stands elicit strong reactions, she wrote. But the kind of bias and resistance to change implied by the memo seem to fall in line with the endless accounts of harassment and a deeply embedded bro culture thatve been well-documented by women across the tech industry, and indicate that Google might need to take a much stronger stand in order to make a real difference.

By firing Damore, the company has made it clear that such hostility wont be tolerated. But Damores memo, and the support it has received from some, has also made it clear that the tech industrys undercurrent of sexism and resistance to change is deeply embedded. And firing a single employee wont solve that problem anytime soon.

Correction: A previous version of this story stated that Damore has a doctorate in systems biology from Harvard, which he listed on his LinkedIn profile. A representative from Harvard has confirmed to Vox that Damore actually has a masters degree in systems biology, not a PhD.

Anthony Mills: Trump’s incidental firestorm – Vallejo Times Herald

Since President Trump announced that transgenders are not allowed to join the United States military, which reverses President Obamas permissive policy, a predictable news media firestorm has taken place. It appears that the Chief Executive gravitates toward that which creates political firestorms. The transgender issue is incidental.

Be that as it may, a basic review of genetics and transgenderism is in order.

Each human has a genetic code: Male XY, female XX. On very rare occasions there a variations to this code, like XXY which would be a female hermaphrodite.

It has now become the fashion for people, especially young people, to question the genetic code that they were born with. This thinking has progressed to confusion and insecurity. Then there older and once successful people like Bruce Jenner who subscribed himself to synthetic hormone therapy and re-assignment surgery to gain the semblance of woman. No matter what surgery any male (or female) takes, not matter how much female hormones Jenner or any other males takes (or male hormones a female takes) the genetic code remains the same.

Jenner along with other transgenders cannot reproduce, hence they are sterile.

The opposition counters what is written above comes from hate, another form of gay-bashing.

The oppositions counters by stating that the genetic code of a person remains the same no matter what surgery, no matter what hormones are taken, that (same-sex marriage) and transgenderism has been accepted by much of the of the world. This is true.

In Israel there are gay pride parades. All of North America and much of South America, along with western European countries, accept transgenderism and same-sex marriage. I met with an Anglican Navy chaplain and made notice to the subject that the Queen of England, who is the ultimate head of the Anglican Church, signed the document that allows same-sex marriage in England. He denied this, he then looked downward and could not contest the fact.

It has been said, it has been written and repeated that there will come a time of the Great Apostasy.

It has been said, it has been written and repeated that some of the elect will be among they who are deceived.

That time is now.

Losing My Hair: If I’m Not Bothered, Why Are You? – Yahoo News UK

Going bald was always a foregone conclusion for me. From a young age, I was aware that I had inherited most of my physical traits from my maternal family. Whereas my father’s side was blessed with voluminous mops of thick, black hair and olive skin, all three of my mother’s brothers and my grandfather were (and obviously still are) bald as coots. I grew up being told repeatedly that a similar fate awaited me and, as foretold, my hairline began to recede around the age of 16. To be honest, given the truly hideous ‘curtain’ hairstyle I was rocking in 1995, many might say this was no bad thing.

However, the years passed and somehow, most of my hair remained. In 2006, my hairdresser, who was always very keen to reassure me that I was ‘unlikely to go bald’ given that I hadn’t done so already, suggested a hairstyle which involved sweeping my hair forward over my forehead and spiking the hair around my crown. This was fairly la mode at that time (but then, so were mullets) and I literally thought nothing of it. It’s only with the benefit of hindsight that I can see that actually, my hairdresser was concealing the inevitable truth and helping me to forestall my follicular fate.

I fared quite well. It wasn’t until the age of 32 that the hair loss was of such an extent that I began to shave my head. Given that the aforementioned uncles had, by all accounts, lost their hair by their late teens, I felt fortunate to have held on to mine for so long. What’s more, I was lucky enough to have a partner who reassured me that they found my shaven look attractive. I am, for want of less dramatic terminology, at peace with my premature baldness. Why, then, are so many other people so disappointed on my behalf?

From my mother – who, frankly, should know better given that it’s her contribution to my genetics that has caused it – to random people I barely know, there is never a shortage of people ready and willing to express their sympathy with my ‘plight’. ‘Are you gutted to have lost your hair at such a young age?’. ‘Have you ever considered a hair transplant?’. ‘It’s such a shame as you had such lovely hair’. The comments are numerous and made without a second thought as to how they might make me feel. For some unfathomable reason, unsolicited remarks about this aspect of someone’s appearance seem to be socially acceptable. Conversely, it is rightly considered to be inappropriate or downright offensive to casually mention a person’s weight gain, physical ageing or acne, for example, ‘Are you devastated to have become so wrinkly?’ is certain to offend and understandably so. There is a double standard at play and it could, for some people, be incredibly damaging.

The curiosity, misplaced sympathy and callousness does make me question whether I should be more perturbed about losing my hair than I actually am. Should I, in fact, be spending more time dolefully gazing into the mirror, lamenting the gradual disappearance of my golden locks and frantically researching ways to return to the ‘glory days’ of hairbrushes, combs, shampoo and regular trips to the barber? I think not. After all, for many, hair loss is symptomatic of serious illness, stress and trauma. To self-indulgently bemoan my male pattern baldness as a relatively healthy man headed for 40 with relatively little to complain about would, for me, feel unseemly.

That’s not to say everyone does or should feel the same. Men who seek to regain (see what I did there?) their beautiful barnets should be neither mocked nor castigated – but neither should those who are at ease with the hand dealt to them by genetics, hormones or a mix of the two. Male pattern baldness continues to be open season for uninvited jest, lampooning and commiseration. It’s insensitive, anti-social and wildly inappropriate. Balding, like any other physical change, affects individuals in a variety of ways – a little consideration for the feelings of others costs nothing.

Now, if you’ll excuse me, I have a date with a certain Mr Remington…

BGU researchers find genetic defect that causes male infertility – The Jerusalem Post

fertility feat 1 88 298.(photo credit:Illustrative photo)

A previously unknown genetic mutation that causes male infertility has been discovered by researchers from the faculty of health sciences at Ben-Gurion University of the Negev and the fertility and in-vitro fertilization unit at Soroka University Medical Center in Beersheba.

Five percent of men suffer from infertility. About a fifth of them have a lack of sperm production, azoospermia, though the reasons are still a mystery.

The study was made with the participation of five men from a single family treated by a team from Sorokas in vitro fertilization unit, led by Prof. Eitan Lunenfeld, chairman of the obstetrics and gynecology department. The men suffered from lack of sperm in their ejaculate and spermatogenic arrest in their testes, but with no obvious cause.

Profs. Ruti Parvari and Mahmoud Huleihel from the Shraga Segal Department of Microbiology and Immunology and the Fertility Research Center discovered a mutation in a gene that is supposed to protect the full DNA sequence in sperm.

The mutation inactivates the function of the gene, thereby arresting the production of sperm. First author on the article was Maram Arafat from Parvaris research group.

The results link damage to this gene with infertility for the first time. As a result of this study, specific scans in the future will be available to test for mutations in this gene, which are important for prognostic and treatment of the couples, the researchers wrote in the Journal of Medical Genetics

Breakthrough: Doctors can now ‘edit’ genes in human embryos – Health24

In a first-ever experiment, geneticists have successfully modified a human embryo to remove a mutation that causes a life-threatening heart condition.

This is the first study to demonstrate that a gene-editing technique can be used in human embryos to convert mutant genes back to their normal version, the researchers said.

This new procedure tackled a genetic mutation in human embryos that causes hypertrophic cardiomyopathy, an inherited condition in which the heart muscle becomes abnormally thick.

The mutation was successfully repaired in 72% of 18 embryos that were created in a lab using sperm from a male donor who carries the hereditary heart condition, said team member Dr Paula Amato. She is an adjunct associate professor of obstetrics and gynaecology at Oregon Health & Science University (OHSU) in Portland.

Unlike other parts of the world in which cardiomyopathy is rare, heart muscle disease is endemic in Africa.

Impact on future generations

The procedure also might work in other genetic diseases caused when a person has one good copy and one mutated copy of a gene, Amato said. These include cystic fibrosis and cancers caused by mutated BRCA genes.

“This embryo gene correction method, if proven safe, can potentially be used to prevent transmission of genetic disease to future generations,” Amato said.

But while the procedure is considered to be the first of its kind, human trials are not currently allowed in the United States.

A serious heart condition

Hereditary hypertrophic cardiomyopathy occurs in about one out of every 500 adults, and is passed along when a person winds up with one good copy and one mutated copy of a gene called MYBPC3, the researchers said.

There’s a 50% chance that the children of a parent with the disease will inherit the genetic mutation for the disease, according to a Mayo Clinic estimate.

People with hypertrophic cardiomyopathy are at increased risk of heart failure and sudden heart death. The condition is the most common cause of sudden death in otherwise healthy young athletes, researchers said in background notes.

How the ‘editing’ is done

To repair the problem, the research team “broke” the mutated version of the MYPBC3 gene inside human embryos, using technology that allows scientists to snip a specific target sequence on a mutant gene.

Scientists discovered that when this occurs, a DNA repair process employed within human embryos activates to fix the broken gene, using the normal copy of the gene as a template.

The result: an embryo with two healthy copies of the gene that, if implanted in a woman and allowed to gestate, should result in a baby free from risk of hereditary cardiomyopathy. Further, any children descended from that baby should also be free from this genetic risk.

The researchers found that when they performed this procedure, all the cells in corrected embryos wound up containing two normal copies of the gene, Amato said. The new report was published in the journalNature.

The next step

Researchers will next focus on testing the safety and improving the efficiency of the CRISPR-Cas9 process, possibly by using other genetic tools in combination with it, Mitalipov said. After that, they could proceed to human trials, in which the corrected embryos would be implanted with the goal of establishing pregnancy.

In the United States, the US Food and Drug Administration is prohibited from considering clinical trials related to germline genetic modification, Amato said. In addition, the US National Institutes of Health are not allowed to use federal funds to promote embryo research. It is possible that human trials could occur in another country with laws allowing such procedures, Mitalipov said.

In the area of stem cell research, South Africa allows the derivation of human embryonic stem cells from excess In vitro fertilization (IVF) embryos, and also allows for the creation of human embryos for research.

Researchers from the Faculty of Health Sciences at Ben-Gurion University of the Negev and the Fertility & In Vitro Fertilization (IVF) Unit at Soroka Medical Center have discovered a new genetic mutation that causes a lack of sperm production.

Five percent of men suffer from infertility, and about one percent suffer from azoospermia, a lack of sperm production, although the reasons for this lack of sperm are still a mystery.

The study was made possible as a result of five men from a single family who were treated at Soroka Medical Center for arrest of sperm in their testes with no obvious cause.

The treatment team at the IVF Unit was led by Prof. Eitan Lunenfeld, chair of the Department of Obstetrics and Gynecology.

Profs. Ruti Parvari and Mahmoud Huleihel from the Shraga Segal Department of Microbiology & Immunology, and the Fertility Research Center discovered a mutation in a gene that is supposed to protect the full DNA sequence in the sperm.

The mutation inactivates the function of the gene and thus the production of sperm is arrested. These results link damage to this gene and infertility for the first time.

As a result of this study, in future, specific scans will be available to test for mutations in this gene, which are important for prognostic and treatment of the couples, the researchers said.

The results of the study, Mutation in TDRD9 causes non-obstructive azoospermia in infertile men, were published recently in the Journal of Medical Genetics. First author on the article is Maram Arafat from Prof. Parvaris research group.

The study was supported in part by The Natural Science Foundation of China (NSFC) Israel Science Foundation (ISF) (NSFC-ISF) (1183/14).

Homosexuality Partly Rooted In Genetics Rather Than Lifestyle Choice, Says Science – Medical Daily

Many of us have been curious as to why some of us are straight or gay; “Why are some of us attracted to the opposite sex?” “Why are some men attracted to men?” “Why are some women attracted to women?” Currently, we don’t know why we vary in sexual orientation, but science suggests being gay at least is partly genetic, rather than a lifestyle choice.

In AsapSCIENCE’s latest video, “Does Everybody Have A Gay Gene,” Mitchell Moffit and Gregory Brown explain genetics and epigenetic factors the study of how the environment can chemically modify our genes can be used to prove that being gay is not a choice.

Read More: Study Finds Same Sex Couples Make Better Parents

A 2016 study, published in the Archives of Sexual Behavior, found linkages in a specific region of the X chromosome labelled Xq28 and in another region of chromosome 8, known as 8q12, in over 400 gay siblings. Traits like hair color, height and intelligence varied between each brothers in a pair and between all groups of brothers. In other words, any single nucleotide polymorphisms (SNPs) differences on a single letter in the genetic code found in the same genetic locations across the group would likely be associated with sexual orientation.

The region on the X chromosome, Xq28, was previously identified in 1993 by Dean Hamer of the US National Institutes of Health in Bethesda, Maryland. However, there needs to be more work done to determine the specific genes involved and how they work, including if there are equivalent genes in women. The study provides researchers with the potential to narrow down fewer genes linked to sexual preference.

The belief that homosexuality is genetic can create a paradox. For example, homosexuals have 80 percent fewerchildren than heterosexuals, which suggests the genes would not be passed down and would eventually die out.

Enter epigenetics.

A 2015 study published in Science used epigenetics to propose that everyone has a gay gene, but it’s contingent on whether the attachment of a methyl group to specific regions of DNA is triggered and turned on. Upon analyzing gay and straight male twins, researchers found a specific methylation pattern was closely linked to sexual orientation. The model was able to predict the sexuality of men with 70 percent accuracy.

However, a caveat of the study is its small sample size, which means there is not too much power to make such a claim. Evidently, there were certain correlations, but a predicting model may not yet be an actual reality. Larger studies are needed to replicate these findings if valid.

A specific gay gene has not been found, but there’s scientific data that suggests sexual orientation is linked to genetics on a molecular level. Previous research has found giving birth to a son increases the odds of homosexuality in the next son by 33 percent. Scientists believe a woman’s body adjusts the androgen level in her womb as she has more sons, and the androgens interactwith genes to produce homosexuality.

The scientific community still has a long way to go when it comes to studying the causes of homosexuality. Currently, most research only focuses on gay men and neglect other groups, like lesbians. Further research on the genetic and epigenetic factors of homosexuality could help reduce homophobic laws around the world by proving it’s not a lifestyle choice.

Science is working on proving the biology of homosexuality, but it also raises the question, does it matter if someone is straight or gay?

Born this way? Researchers explore the science of gender identity – Reuters

NEW YORK (Reuters) – While President Donald Trump has thrust transgender people back into the conflict between conservative and liberal values in the United States, geneticists are quietly working on a major research effort to unlock the secrets of gender identity.

A consortium of five research institutions in Europe and the United States, including Vanderbilt University Medical Center, George Washington University and Boston Children’s Hospital, is looking to the genome, a person’s complete set of DNA, for clues about whether transgender people are born that way.

Two decades of brain research have provided hints of a biological origin to being transgender, but no irrefutable conclusions.

Now scientists in the consortium have embarked on what they call the largest-ever study of its kind, searching for a genetic component to explain why people assigned one gender at birth so persistently identify as the other, often from very early childhood. (reut.rs/2w3Ozg9)

Researchers have extracted DNA from the blood samples of 10,000 people, 3,000 of them transgender and the rest non-transgender, or cisgender. The project is awaiting grant funding to begin the next phase: testing about 3 million markers, or variations, across the genome for all of the samples.

Knowing what variations transgender people have in common, and comparing those patterns to those of cisgender people in the study, may help investigators understand what role the genome plays in everyone’s gender identity.

“If the trait is strongly genetic, then people who identify as trans will share more of their genome, not because they are related in nuclear families but because they are more anciently related,” said Lea Davis, leader of the study and an assistant professor of medicine at the Vanderbilt Genetics Institute.

The search for the biological underpinnings is taking on new relevance as the battle for transgender rights plays out in the U.S. political arena.

One of the first acts of the new Trump administration was to revoke Obama-era guidelines directing public schools to allow transgender students to use bathrooms of their choice. (reut.rs/2l8pWJe) Last week, the president announced on Twitter he intends to ban transgender people from serving in the military. (reut.rs/2uXF8kG)

Texas lawmakers are debating a bathroom bill that would require people to use the bathroom of the sex listed on their birth certificate. (reut.rs/2tXKbgV) North Carolina in March repealed a similar law after a national boycott cost the state hundreds of millions of dollars in lost business. (reut.rs/2nGg1OH)

Currently, the only way to determine whether people are transgender is for them to self-identify as such. While civil rights activists contend that should be sufficient, scientists have taken their search to the lab.

That quest has made some transgender people nervous. If a “cause” is found it could posit a “cure,” potentially opening the door to so-called reparative therapies similar to those that attempt to turn gay people straight, advocates say. Others raise concerns about the rights of those who may identify as trans but lack biological “proof.”

“It’s an idea that can be wielded against us, depending on the ideology of the user,” said Kale Edmiston, a transgender man and postdoctoral scholar at the University of Pittsburgh specializing in neuroimaging.

Dana Bevan, a transgender woman, psychologist and author of three books on transgender topics, acknowledged the potential manipulation of research was a concern but said, “I don’t believe that science can or should hold back from trying to understand what’s going on.”

Davis stressed that her study does not seek to produce a genetic test for being transgender, nor would it be able to. Instead, she said, she hopes the data will lead to better care for transgender people, who experience wide health disparities compared to the general population. (reut.rs/2cyp674)

One-third of transgender people reported a negative healthcare experience in the previous year such as verbal harassment, refusal of treatment or the need to teach their doctors about transgender care, according to a landmark survey of nearly 28,000 people released last year by the National Center for Transgender Equality.

Some 40 percent have attempted suicide, almost nine times the rate for the general population.

“We can use this information to help train doctors and nurses to provide better care to trans patients and to also develop amicus briefs to support equal rights legislation,” said Davis, who is also director of research for Vanderbilt’s gender health clinic.

The Vanderbilt University Medical Center in Tennessee has one of the world’s largest DNA databanks. It also has emerged as a leader in transgender healthcare with initiatives such as the Trans Buddy Program, which pairs every transgender patient with a volunteer to help guide them through their healthcare visits.

The study has applied for a grant from the National Institutes of Health and is exploring other financial sources to provide the $1 million needed to complete the genotyping, expected to take a year to 18 months. Analysis of the data would take about another six months and require more funding, Davis said.

The other consortium members are Vrije University in Amsterdam and the FIMABIS institute in Malaga, Spain.

Until now, the bulk of research into the origins of being transgender has looked at the brain.

Neurologists have spotted clues in the brain structure and activity of transgender people that distinguish them from cisgender subjects.

A seminal 1995 study was led by Dutch neurobiologist Dick Swaab, who was also among the first scientists to discover structural differences between male and female brains. Looking at postmortem brain tissue of transgender subjects, he found that male-to-female transsexuals had clusters of cells, or nuclei, that more closely resembled those of a typical female brain, and vice versa.

Swaab’s body of work on postmortem samples was based on just 12 transgender brains that he spent 25 years collecting. But it gave rise to a whole new field of inquiry that today is being explored with advanced brain scan technology on living transgender volunteers.

Among the leaders in brain scan research is Ivanka Savic, a professor of neurology with Sweden’s Karolinska Institute and visiting professor at the University of California, Los Angeles.

Her studies suggest that transgender men have a weakened connection between the two areas of the brain that process the perception of self and one’s own body. Savic said those connections seem to improve after the person receives cross-hormone treatment.

Her work has been published more than 100 times on various topics in peer-reviewed journals, but she still cannot conclude whether people are born transgender.

“I think that, but I have to prove that,” Savic said.

A number of other researchers, including both geneticists and neurologists, presume a biological component that is also influenced by upbringing.

But Paul McHugh, a university professor of psychiatry at the Johns Hopkins School of Medicine, has emerged as the leading voice challenging the “born-this-way” hypothesis.

He encourages psychiatric therapy for transgender people, especially children, so that they accept the gender assigned to them at birth.

McHugh has gained a following among social conservatives, while incensing LGBT advocates with comments such as calling transgender people “counterfeit.”

Last year he co-authored a review of the scientific literature published in The New Atlantis journal, asserting there was scant evidence to suggest sexual orientation and gender identity were biologically determined.

The article drew a rebuke from nearly 600 academics and clinicians who called it misleading.

McHugh told Reuters he was “unmoved” by his critics and says he doubts additional research will reveal a biological cause.

“If it were obvious,” he said, “they would have found it long ago.”

Losing your hair? There isn’t a cure for male baldness – but here are the two effective treatments – Mirror.co.uk

For women, their hair is supposed to be their crowning glory – but it turns out men are just as sensitive about their barnets.

Even if you’ve been eating well, taking regular exercise and getting lots of sleep, you may have genetics to blame for your eventual hair loss.

It follows a distinctive pattern. Generally, a little thinning of the hair my be noticeable first form the temples and the crown of the head, followed by wider hair loss allowing more of the scalp to become visible.

This may happen to some men as early as late teenage years, but for most it happens in their late 20s and early 30s.

In the form of male pattern baldness, as described above, this is a genetic disorder.

It occurs when hair follicles convert testosterone into another hormone called hihydrotestosterone (DHY).

Affected hair follices (typically those at the sides or top of the head) become more sensitive to DHT, which causes the hair follicles to weaken, shrink and eventually die. This slows down hair production and can stop growth altogether.

Asda Partnership

There isn’t a cure for hair loss or baldness, yet, but hair loss treatment can prevent further loss and even lead to renewed hair growth.

The two most effective hair loss treatment available in the UK are Minoxidil and Finasteride.

Minoxidil is a lotion or foam that you rub into your scalp, and it can be obtained from pharmacies without a prescription.

Finasteride comes in the form of an oral tablet.

Finasteride has proven to be 93% effective for the majority of men aged between 18-41 who took it for five years.

Studies have show that best results occur after two years, when hair growth is at its thickest.

Hair loss prevention only lasts while you are taking the treatement. If you stop taking Finasteride, you may lose some hair.

Earlier this year, Harold Bornstein, the doctor who looks after President Trump’s health, told the New York Times that both he and The Donald take a regular small dose of the drug, which is known as Propecia in the US.

England football legend Wayne Rooney reportedly took the treatment as well before he had a hair transplant.

Asda is the only supermarket to sell the treatment without prescription, after seeing a pharmacist. It’s also available from high street chemists. Prices are as follows for a 28 day supply

Pair of lion cubs born at Idaho Falls Zoo – Post Register

The Idaho Falls Zoos lion pride grew last month following the birth of two female cubs.

The delivery comes only five months after the zoos African lioness, Kimani, became a first-time mother to a male cub, Hondo, in February.

The back-to-back pregnancies were the result of unique circumstances, a city of Idaho Falls news release said. At the advanced age of 14 with no successful pregnancies before Hondo, Kimani having cubs was doubtful.

After Hondo was separated from his mother to receive lifesaving treatment, she became pregnant again.

These two new cubs are good news, Animal Keeper Dallas LaDucer said in the release. Their mother, Kimani, has a unique set of genetics and it is important that they are passed on to future generations.

The cubs are with their mother away from public view, but zoo employees will post photos, videos and updates on the zoos Facebook page and Instagram account. The cubs will be reunited with their father and older brother after developing sufficiently, the release said.

Typically, zoo employees would expect cubs every few years, though back-to-back pregnancies are more common in the wild when a lioness loses her cubs.

The cubs join a handful of babies born at the zoo this year.

With everything that has happened with our lions, hand raising one of only 16 grey gibbons in the country, a sloth bear cub, a camel calf, the first red-crowned crane chick in the zoos history and all the other babies, it has been a wild and wonderful year at the zoo! Operations Manager Linda Beard said in the release.

Do You Prefer Sleep Or Sex? Fruit Flies Know – Daily Beast

This weekend, many thousands of sleepy women will submit to their male partners prodding, middle-of-the-night sexual advancesbegrudgingly, at first, then perhaps with unexpected enthusiasm.

When they wake up possibly tired and contemptuous of the prodder who disturbed their rest, they may curse the patriarchy. They may blame their submissive swoons on a combination of sexist conditioning and toxic masculinity, because they are enlightened feminists.

But biology offers another explanation that could take the edge off these morning-after moods.

A new study of male and female fruit flies has found that females are receptive to sexual advances even when sleep-deprived. Males, by contrast, are less likely to court females when sleep-deprived, according to the study, which also found that males are less likely to sleep when aroused.

Published Friday in the Nature Communications journal, the study suggests that the circle of fruit fly life depends on male desire being adequately sated. And its findings about fruit flies sleep and sex patterns may shed light on whyand whenmen and women choose sleep over sex, and vice versa.

This is partly because there is a tremendous similarity in the genes of human beings and fruit flies, according to Michael Nitabach, the studys lead author and a professor of genetics and cellular physiology at Yale University.

In addition to gene similarities, fruit flies engage in numerous behaviors that human beings and other mammals engage in, including sex, sleep, learning, memory, sensory experience, and decision making.

The fruit fly is also a useful model organism for understanding the neural control of behavior, said Nitabach. They have an extensive collection of powerful genetic tools, like those we used in this study, for manipulating and measuring function in specific subsets of neurons involved in particular behaviors.

Nitabachs latest study backs up previous fruit fly research: genes already identified in prior studies as important for distinguishing male and female sex differences in anatomy, physiology and sexual behavior are also important for determining sex differences in sleep, he said.

Sexual similarities between fruit flies and humans extend well beyond how arousal affects their sleep.

Male fruit flies have a habit of chasing their pray like adolescent boys, and they engage in a kind of seduction dance that involves extending and vibrating a single wing, according to Nitabach, before mounting. The mating process lasts 15 to 25 minutes, beginning with chase and finishing when the male, well, finishes.

Nitabach and his colleagues measured the flies sexual activity by placing a male and female together in a chamber about a half inch in diameter and video-taping their behavior, he said. Extended periods of immobility determined when the flies had fallen asleep, exhausted from exertion.

We used sophisticated genetic tools to make small numbers of specific neurons whose activity determines sex drive sensitive to temperature, said Nitabach. When we then elevated the temperature, this activated these sex-drive neurons. We then measured sleep of these flies with activated sex-drive neurons and found that in males sleep was substantially reduced.

Nitabachs study found that sex-drive neurons suppress sleep in male flies, and sleepiness suppresses their sex drive. This discovery paves the way for future studies to explore details of the connection between sex-drive and sleep-control neurons, according to Nitabach, and for further analysis of exactly how these genes regulate sleep.

Nitabach also said that sleep and sex patterns identified in male and female fruit flies may indeed apply to men and women, but confirming this hypothesis would require further experimentation.

The male fruit fly has a prodigious sperm count: the size of their ejaculate makes them record holders among animal species, according to a 2016 study at the University of Zurich. While the fruit fly is only a millimeters long, its sperm reach an impressive length of almost six centimeters, according to the studys author.

The cold, biological truth is that fatigue doesnt make female fruit flies any less receptive to sex because they cant afford to pass up an opportunity to reproduce. Tired male fruit flies, by contrast, are less likely to seduce because they cant get it up to perform.

Its not an empowering feminist narrative. But it should deter women from flagellating themselves after succumbing to their partners advances. Their submissive, middle-of-the-night swoons may have nothing to do with being weak-willed or conditioned to please men. Its just science.

Akron Zoo mourns death of male snow leopard – Ravenna Record Courier

By TIM TROGLEN Staff Writer Published: July 31, 2017 12:57 PM

AKRON The Akron Zoo announced today that Roscoe, a 14-year old male snow leopard, was euthanized on July 26 after being diagnosed with a fast-growing cancer that severely affected the bone in his lower jaw.

According to Doug Piekarz, Akron Zoo president CEO, Roscoe has been a beloved member of our family since he arrived from San Antonio. He will be missed by all of us. I want to thank our professional animal care staff who cared for him attentively every day, and our veterinary care staff who so diligently treated him during his illness to ensure his welfare,

According to the Snow Leopard Trust, at least one snow leopard is killed each day in the wild. With only a few thousand left on earth, we recognize the importance of the work we are doing to ensure the Snow Leopards survival. Roscoe will continue to play a critical role with his genetics preserved to help create a more genetically diverse future generation of snow leopards.

According to zoo officials, the median life expectancy of a snow leopard is 14 years old.

Roscoe was a resident of the Akron Zoo since 2004 and sired seven cubs while in Akron, three of which are still at the zoo.

Roscoe will be missed deeply by the zoo staff, volunteers and community, said Dr. Kim Cook, Akron Zoo director of animal health and conservation. He was a laid-back cat who had a great bond with Shanti. In fact they were able to be together at all times, which is rare for snow leopards, which are typically solitary animals.

Officials noticed Roscoe was not feeling well a few weeks ago through a change in his appetite and behavior.

The vet staff at the zoo performed an exam, which led to the diagnosis of squamous cell carcinoma bone cancer in Roscoes jaw. His appetite and activity began to rapidly decrease and the decision was made to humanely euthanize Roscoe. His annual preventive medicine exam last summer showed no signs of the cancer.

Snow leopards are an endangered species, and the zoo participates in the Association of Zoos and Aquariums Snow Leopard Species Survival Plan, which includes a total of 167 snow leopards. Participation in the program has led to three successful litters with Roscoe and the zoos female snow leopard Shanti. Two cubs were born in 2012 and 2014, and three cubs were born in 2016 and are still at the Akron Zoo, according to officials. The other four cubs are at other AZA-accredited zoos in the U.S.

In 2010 and 2012, the Akron Zoo worked with researchers to freeze Roscoes sperm to potentially use in the future for artificial insemination. With the advances in veterinary medicine, Roscoes legacy could continue for many generations and help prevent the extinction of snow leopards.

Roscoe was born May 18, 2003, at the San Antonio Zoo and came to the Akron Zoo Dec. 15, 2004.

How Sterile Insect Technology could combat one of horticulture’s most damaging pests – ABC Online

A team of scientists in South Australia are providing a powerful new line of defence against one of horticulture’s most damaging pests.

The National Sterile Insect Facility in Port Augusta, is set to produce 50 million sterile male Queensland fruit flies a week by 2019.

The ambitious three-year project is all in a bid to safeguard the multi-billion dollar horticulture industry across South Australia and Victoria.

The Sterile Insect Technology (SIT) is the first insect pest control method that uses genetics, or a widescale form of insect birth control.

The technique involves breeding fruit flies and sterilising the males with an x-ray before they are released into an area with a wild population.

These sterile male flies are then released over infested areas, where they mate with wild females who eventually become outnumbered and die out.

The $45 million SITPlus initiative, led by Horticulture Innovation Australia, complements the state-of-the-art facility in Port Augusta, approximately 350 kilometres from Adelaide.

Program director Dan Ryan took SA Country Hour for an exclusive tour through the $3.8 million factory.

He said the whole process began in the egg collection room where the team was breeding up to 50 million flies per week.

“We’ve got males and females in here; [they] are in there to have sex, so this is the exciting room for the flies,” he said.

“What we’ve got is a surface that the females can overposit or lay eggs into and then we collect those eggs, we put them on a larval tray where the eggs can hatch into larvae.

“Then the larvae mature and they go to a pupal rearing room, [where] we raise the pupae. They mature inside the pupae which is just a little shell.”

Flies in the SIT facility are marked with a bright pink dye so they can be identified in the wild.

Mr Ryan said once the flies leave the pupal rearing room, they were covered with a distinctive dye so they could be easily identified in the wild.

“We mark the pupae because we need to know when we get out in the wild; is this a fly that’s come from a factory and is sterile or is this a wild fly,” he said.

“So what we do is cover them with a bright iridescent dye on the pupae, then the fly comes out of the pupae and gets covered in dye.

“We do have back-up processes to identify them; in the very rare occurrence that there is no dye on a fly we have two tests which will verify it.”

Mr Ryan said from the dye-marking room, the flies are x-rayed and ready for release into the wild.

“We all think of x-rays with broken arms but these flies are getting x-rays to become sterile,” he said.

“It’s a very low dose of x-ray because as you can imagine, it doesn’t take much to make a fly sterile but we have a 100 per cent success rate.

“[On release] these sterile flies go out and trick the wild females and the population crashes, it’s a horrible trick on the wild female flies but is all part of protecting horticulture in Australia.”

Queensland fruit fly destroys an estimated $300 million of fruit and vegetable crops every year.

Mr Ryan said the SIT program was a ‘game-changer’ for management of the Queensland fruit fly across south eastern Australia.

Queensland fruit flies destroys an estimated $300 million dollars of fruit and vegetable crops every year.

He said the facility would not only ensure South Australia’s remains fruit fly-free but would also help reduce populations across the country.

“South Australia markets horticulture overseas based on freedom from Queensland fruit fly, that’s worth a lot of money to the industry,” he said.

“If they lost that market access it would really impact the value of their businesses, so this is all about protecting those businesses.

“Another use is for areas where you have large isolated farms, so a good example of that might be Hillston NSW, where you’ve got a collection of large citrus farms and a cherry farms.

“It’s a great place to put that pressure down and perhaps establish longer term another pest-free area.

“The third use is helping farmers in endemic areas manage the flies; one of the problems growers have is they can manage the fly on their farm but they’re always getting reinvasion from off the farm.”

SIT program director Dan Ryan says the facility aims to breed 50 million flies per week by 2019.

“It’s the first purpose-built fruit-fly facility in Australia, to make sure that we could significantly ramp up the number of flies that we could get out of the factory,” he said.

“This [will enable us] to provide flies right across south eastern Australia for those areas that need it.

“This is moving from a solution in a can and just trying to use chemicals to control a problem, to using new innovative technology in terms of sterile insects.

“It’s going to be more long-term, it’s going to be good for the producer, it’s going to be good for the environment [and] its going to be good for consumers.”

Mr Zacharin said he was confident the program could help other major horticultural regions across southern NSW and Victoria strive towards becoming fruit fly-free.

“We’ve looked at facilities overseas that produce up to a billion flies a week, so on world terms this is a small facility,” he said.

“But it’s about demonstrating to industries and communities that releasing sterile flies is a better way to go in the long-term.

“If we can prove this works very well in the Australian environment, there’s no reason why we can’t push fruit fly freedom from where we are in SA, right across the Murray corridor, into southern NSW and Victoria.

“That will increase productivity for growers and will also give them better access to international markets.”

South Australia is the only mainland State which remains fruit fly free in the country.

The nose on those is rather defined in the tip area which makes very nice button noses but not much else. I also wanted to take the time to fix a few other issues on the originals. The eyelids were bothering me, for example, among other things.

So I came up with Silk, its a smoother, more highlighted less shaded version of my original faces. The entire nose length is smooth and highlighted and I have muted a lot of the shaded areas on the face, for example the eye socket area, undereyes and the cheeks. The lip texture was smoothed and softened and the eyelid area was neatened up with the tear-ducts scaled down slightly.

Here is Silk:

From then I started playing with the nostril area and I ended up with a face that had a more defined nostril. I couldnt decide which I preferred and I knew that some of you would like silk whilst others would like velvet, so I decided to publish both.

Here is Velvet:

Here is a comparison of the three skins:

The elder face skins were also smoothed out a little to match the Silk & Velvet YA skins. The noses were changed accordingly.

Both faces come in Default and Non-Default and will match up with my Naughty & Nice and my Busty St Clair body skins.They also have custom sliders which have the names printed on them. The dots are black & white and the sliders come in a range of colours.

If you have previously downloaded the full set of Default Naughty & Nice Face/Body skins and wish to use one of these faces instead, then I suggest you remove the Naughty & Nice full set and just install the bodies instead then you can choose which faces you like.

You can download one of these faces as your default if you wish, and you can also have the other as a non-default. At the moment I have my Naughty & Nice faces installed, my Busty st Claire bodies and I have Silk and Velvet as non-defaults.

Enjoy

When the male fruit fly gets a headache – Haaretz

We females always knew we could have sex when asleep, not that we want to, and that men can’t. It turns out the same applies to fruit flies.

A vast international study by multiple institutions one can’t have too many studying woo-woo in fruit flies has concluded that when male Drosophila are sleep-deprived, their interest in courtship disappears.

When the female is bushed, nothing happens to their mating behavior.

One way to deprive a fruit fly of sleep, would seem to be to offer it sex. The team also realized that aroused male Drosophilae got little sleep. Sexually aroused females slept fine.

Given the nature of the beasts, animals have to choose between sex and sleep. At least, the males do they can’t do both at the same time. Now scientists have found how the choice is regulated, at least in the fruit fly.

“An organism can only do one thing at a time,” states the team, with Prof. Michael Nitabach of Yale, an expert on molecular physiology and genetics, in Nature Communications. “What we have discovered is a neuronal connection that regulates the interplay between courtship and sleep.”

What Nitabach and his colleagues from the Howard Hughes Medical Institute, the Southeast University in China, and the University of San Diego, did is to study the neuronal activity involved in sex and sleep. They found that sleep-deprived male flies lost interest in courtship, but the females’ mating behavior was unaffected.

Darwin would be proud

The evolutionary explanation they offer is a trivial one. The males’ behavior is easily explained as adaptive: Falling asleep during sex is not a good way to pass on your genes, they stated.

But, they wondered, why are females still receptive to male advances when sleepy? One possibility is that as the recipient, they can afford to be. Another, postulated by Nitabach, is that the females can’t afford to pass up an eligible suitor. But there are a lot of fruit flies out there. Ostensibly, the females would seem to be spoiled for choice.

The team also found functional connections between the different nervous centers that mediate sex and sleep, they say. Nitabach’s conclusion is that whichever behavior has the highest biological drive at a given moment physiologically suppresses the yen for the other behavior. Thus, when a boy fly wants sleep badly enough, it depresses his sex drive, and vice versa.

So, is the human drive for sex and the human desire for sleep also controlled by our neurons? Probably, at least to some degree. Just like the fruit fly, there are other factors in play.
