New Placenta Model Could Reveal How Birth Defect-Causing Infections Cross from Mom to Baby Mar. 4, 2016 Researchers have devised a cell-based model of the human placenta that could help explain how pathogens that cause birth defects cross from mother to unborn ... read more Mar. 3, 2016 Scientists have developed an animal model for breast cancer that faithfully captures the disease. Tested on human breast tissue, this the most clinically realistic model of breast cancer to ... read more Mar. 2, 2016 A faster, less expensive method has been developed and used to learn the DNA sequence of the male-specific Y chromosome in the gorilla. The research reveals that a male gorilla's Y chromosome is ... read more Mar. 2, 2016 DNA does not always adopt the form of the double helix which is associated with the genetic code; it can also form intricate folds and act as an enzyme: a deoxyribozyme. Scientists have solved the ... read more Mar. 2, 2016 Every cell in our bodies has its proper place, but how do they get there? A research group has discovered the mechanism for a mosaic pattern formation of two different cell types. Their discovery has ... read more Need for Better Characterized Genomes for Clinical Sequencing Mar. 1, 2016 Challenges in benchmarking difficult, but clinically important regions of the genome have been reported. The results underscore the need to extend benchmarking references against which sequencing ... read more A New Way to Stretch DNA Mar. 1, 2016 Researchers have recently developed a new way to controllably manipulate materials, in this case biomolecules that are too small to see with the naked eye. By stretching molecules like DNA and ... read more Mar. 1, 2016 This is a story about spit. Not just any spit, but the saliva of cyst nematodes, a parasite that literally sucks away billions in profits from soybean and other crops every year. Scientists find how ... read more Mar. 1, 2016 Our innate immune system uses two mechanisms. The first kills foreign bodies within the phagocyte itself. The second kills them outside the cell. Microbiologists have discovered that a social amoeba ... read more Preserved Siberian Moose With the DNA of Ancient Animal Discovered Mar. 1, 2016 Scientists have found preserved moose in Western Siberia that have unique features of DNA structure. This discovery will help determine the origin and path of moose movement in the last few tens of ... read more Unlocking the Secrets of Squid Sucker Ring Teeth Feb. 29, 2016 A squid has more in common with a spider than you may think. The razor-sharp 'teeth' that ring the suckers found on some squid tentacles are made up entirely of proteins remarkably similar ... read more Female Fertility Is Dependent on Functional Expression of the E3 Ubiquitin Ligase Itch Feb. 29, 2016 Protein ubiquitination is known to result in its proteasomal degradation or to serve as a signal for tissue-specific cellular functions. Here it is reported that mice with a mutant form of the E3 ... read more Cell Biology: Nuclear Export of Opioid Growth Factor Receptor Is CRM1 Dependent Feb. 29, 2016 The opioid growth factor receptor (OGFr) interacts with a specific opioid growth factor ligand (OGF), chemically termed [Met5]-enkephalin, to maintain homeostasis in a wide variety of normal and ... read more Feb. 29, 2016 DNA is made from four nucleosides, each known by its own letter -- A, G, C, and T. However, since the structure of DNA was deciphered in 1953, scientists have discovered several other variants that ... read more Feb. 29, 2016 Researchers have engineered microbes that can't run away from home. Any refugees that do quickly die without protective proteins produced by their peers. Dubbed 'swarmbots' for their ... read more Blood Vessels Sprout Under Pressure Feb. 29, 2016 It is blood pressure that drives the opening of small capillaries during angiogenesis. A team of researchers has observed the process for the first ... read more Feb. 29, 2016 A team of researchers has identified a new mechanism that regulates the effect of the satiety hormone leptin. The study identified the enzyme HDAC5 as key factor in our control of body weight and ... read more Making Better Enzymes and Protein Drugs Feb. 29, 2016 Natural selection results in protein sequences that are only soluble to the level that is required to carry out its physiological function. However, in biotechnological applications, we need these ... read more Feb. 29, 2016 The development of every animal in the history of the world began with a simple step: the fusion of a spermatozoon with an oocyte. Despite the ubiquity of this process, the actual mechanisms through ... read more Preventing Protein Unfolding Feb. 26, 2016 A computational model shows that polymers can reinforce proteins to prevent them from unfolding under mechanical ... read more
