- Discovery of extremely long-lived proteins may provide insight into cell aging and neurodegenerative diseases
One of the big mysteries in biology is why cells age. Now scientists report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.

Newly divorced middle aged women are more vulnerable to contract HIV and other sexually transmitted diseases, according to new research, because they tend to let their guard down with new sexual partners and avoid using protection since they are not afraid of getting pregnant.

Sequencing a patient's entire genome to discover the source of his or her disease is not routine, but geneticists are getting close. A case report shows how researchers can combine a simple blood test with an "executive summary" scan of the genome to diagnose a severe glycosylation disorder.

Around the world coral reefs are facing threats brought by climate change and dramatic shifts in sea temperatures. While warming has been the primary focus for scientists and ocean policy managers, cold can also cause significant damage. Scientists have shown that cool temperatures can inflict more damage in the short term, but heat is more destructive in the long run.

Researchers have identified how resveratrol, a naturally occurring chemical found in red wine and other plant products, may confer its health benefits. The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found that resveratrol inhibits certain types of proteins known as phosphodiesterases (PDEs), enzymes that help...

'Yellow biotechnology' refers to biotechnology with insects -- analogous to the green (plants) and red (animals) biotechnology. Active ingredients or genes in insects are characterized and used for research or application in agriculture and medicine. Scientists in Germany are now using a procedure which brings forward ecological research on insects: They study gene functions in moth larvae by mani...

Salmonella remains a serious cause of food poisoning, in part due to its ability to thrive and quickly adapt to the different environments in which it can grow. New research has taken a detailed look at what Salmonella does when it enters a new environment, which could provide clues to finding new ways of reducing transmission through the food chain and preventing human illness.

What would you do if you found out that the roads you drive on could cause cancer? This is the reality that residents face in Dunn County, North Dakota. For roughly 30 years, gravel containing the potentially carcinogenic mineral erionite was spread on nearly 500 kilometers of roads, playgrounds, parking lots, and even flower beds throughout Dunn County.
