Endangered Animals Can Be Identified by Rate of Genetic Diversity Loss Aug. 31, 2015 A new study presents a novel approach for identifying vertebrate populations at risk of extinction by estimating the rate of genetic diversity loss, a measurement that could help researchers and ... read more Aug. 31, 2015 Among birds, the line between species is often blurry. Some closely related species interbreed where their ranges overlap, producing hybrid offspring. In the coastal marshes of New England, this has ... read more Aug. 31, 2015 A new species of giant file clam from Atlantic Canadian waters has been described by Canadian scientists. The 'cryptic' clam, which lives in deepwater canyons, was first found off the coast ... read more Aug. 31, 2015 The process of endocytosis -- how cells 'eat' by absorbing molecules -- drives rapid embryonic healing, scientists have discovered. They suggest the results should be used to design better ... read more Aug. 31, 2015 From 1952, DNA was sequenced, modified and extensively studied, but no technique was able to produce clear direct images of DNA. Now, researchers have developed a new technique to produce a direct ... read more Aug. 28, 2015 Viruses are able to redirect the functioning of cells in order to infect them. Inspired by their mode of action, scientists have designed a "chemical virus" that can cross the double lipid ... read more Aug. 28, 2015 Researchers have for the first time created and used a nanoscale vehicle made of DNA to deliver a CRISPR-Cas9 gene-editing tool into cells in both cell culture and an animal ... read more Aug. 28, 2015 Scientists have predicted how biological circuits generate rhythms and control their robustness, utilizing mathematical modeling based on differential equations and stochastic parameter ... read more Aug. 28, 2015 A growing, dividing cell uses most of its energy store to make its "protein factories," the ribosomes. An important player in their "assembly" is the exosome, a molecular ... read more Aug. 28, 2015 Nuclear pores in the nuclear membrane do not only control the transport of molecules into and out of the nucleus but also play an important role in gene expression. Researchers have deciphered a ... read more Aug. 27, 2015 Biochemists have solved the architecture of the nuclear pore complex's complicated inner ring, a subcomplex that is central to the cellular machine's ability to serve as a barrier and ... read more Scientists Identify Possible Key in Virus, Cancer Research Aug. 27, 2015 Scientists have uncovered a viral protein in the cell that inhibits the major DNA sensor and thus the body's response to viral infection, suggesting that this cellular pathway could be ... read more Aug. 27, 2015 Scientists create a biological circuit by programming bacteria to alter gene expression in an entire population. They have created a biological equivalent to a computer circuit that involves multiple ... read more Aug. 27, 2015 Scientists can now watch dynamic biological processes with unprecedented clarity in living cells using new imaging techniques. The new methods dramatically improve on the spatial resolution provided ... read more HIV Particles Do Not Cause AIDS, Our Own Immune Cells Do Aug. 27, 2015 Scientists have discovered that HIV does not cause AIDS by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. In a new ... read more Aug. 27, 2015 RNA can be translated into protein or transformed into gene-regulating molecules. A newly discovered 'reader' protein recognizes a chemical instruction tag affixed to RNA, an important step ... read more Getting a Picture of the Molecules in a Cell in Just Minutes Aug. 27, 2015 Scientists can now take a peek into a single plant cell and -- within minutes -- get a view of the small molecules, including metabolites, hormones, nutrients, and lipids, inside ... read more How Dynamin Mediates Membrane Constriction and Scission Aug. 27, 2015 Cells continually form membrane vesicles that are released into the cell. If this vital process is disturbed, nerve cells, for example, cannot communicate with each other. The protein molecule ... read more Aug. 27, 2015 Cell mechanics are considerably more complex than previously thought and may affect cell structures at various ... read more Aug. 27, 2015 A new study has found that the genetic diversity of wild plant species could be altered rapidly by anthropogenic climate ... read more
