Fishermen Discards Could Increase Prevalence of Turtle Disease in Turks and Caicos

Aug. 27, 2015 — The team surveyed cases of green turtle fibropapillomatosis disease, which creates unsightly pink tumors on the turtles' flesh. Although benign, they can impede turtles' vision 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

Mating With the Wrong Insect May Cut Yellow Fever Mosquito Populations

Aug. 27, 2015 — Asian tiger mosquitoes can drive down yellow fever mosquito populations when the female chooses the wrong male with which to mate, UF/IFAS scientists say. Both insects transmit chikungunya and ... 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

Mystery of Polar Bear Knut's Disease Finally Solved

Aug. 27, 2015 — Knut, the famous polar bear of the Berlin Zoological Garden died of encephalitis. However, the cause of his disease has remained elusive until now. Biologists have now solved the case: The bear ... read more
