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 — 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 — In all organisms, water's pH has a profound effect. Because the interaction of carbon dioxide and water explains the natural acidity of water and all accompanying reactions, it is considered a ... 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. 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

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

Aug. 27, 2015 — Researchers have evidence in support of a clearly defined depth limit for deep-sea fishing in Europe. The findings come just as the European Union considers controversial new legislation to manage ... read more

Mammary Gland Is Shaped by Adaptive Immune System During Development

Aug. 27, 2015 — In experiments with mouse tissue, researchers have discovered that the adaptive immune system, generally associated with fighting infections, plays an active role in guiding the normal development of ... 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

Aug. 27, 2015 — Researchers demonstrate how gram-negative bacteria deliver toxins to kill neighboring ... read more

Aug. 26, 2015 — A new study is providing a clearer picture of the evolutionary history and genetic organization of cannabis, a step that could have agricultural, medical and legal implications for this valuable ... read more

Paralysis: Primates Recover Better Than Rodents

Aug. 26, 2015 — Monkeys and humans exhibit greater motor recovery than rats after similar spinal cord injury, according to a new ... read more

Aug. 26, 2015 — New insight into methanotrophs, bacteria that can oxidise methane, may help us develop an array of biotechnological applications that exploit methane and protect our environment from this potent ... read more

Aug. 26, 2015 — For more than a decade, gene sequencers have been improving more rapidly than the computers required to make sense of their outputs. Searching for DNA sequences in existing genomic databases can ... read more
