New research examines genetics of successful aging

...Pittsburgh, is among the first to identify genetic links to cognitive longevity. "While successful aging has been defined in many ways, we focused on individuals who had reached at least 90 without significant decline in mental capacity," said lead researcher George S. Zubenko, MD, PhD, Professor of Psy...

Texas scientists discover how a hepatitis C protein promotes liver cancer

...The molecular mechanism is similar to the one that links the human papilloma virus (HPV), the cause of genital warts, and cervical cancer, according to Dr. Stanley M. Lemon, the senior author of a paper on the discovery that will be published this week in the online early edition of the Proceedings of the ...

"This ability to find links between sets of proteins involved in different genetic disorders offers a novel approach for more rapidly identifying new candidate genes involved in human diseases," he says. The analysis included interactions among 1,077 genes coding for proteins...

CU, USDA team to curb two invasive, poisonous vines

...es studies of the plants' biology to identify weak links in the life cycle that should be targeted, if possible, for biological control," said Lindsey Milbrath, a USDA-ARS research entomologist at Cornell, adding that introducing any agent will require federal approval. "Our research will help guide the se...

Nano machine switches between biological and silicon worlds

... if the biological motor is working, so the switch links the biological world with the silicon world of electronic signals. Here's how it works. The team uses a microfluidics chip that includes a number of channels measured in nano-metres. The novelty of microfluidics is that it can channel liquids in lam...

Extinctions linked to climate change

A new report that links global warming to the recent extinction of dozens of amphibian species in tropical America is more evidence of a large phenomena that may affect broad regions, many animal species and ultimately humans, according to researchers at Oregon State Univer...

Researchers unravel DNA tangles and enzyme seamstresses

.... "One link could keep the cell from dividing. Two links are even more lethal," says Zechiedrich, who notes that "the results of these computer simulations are very striking." While Chan and his collaborators stress their results represent only a quantitative proof of concept, they do see the finding as p...
