New tool reveals mutations that cause HIV-drug resistance

Protease inhibitor drugs are one of the major weapons in the fight against HIV, the virus that causes AIDS, but their effectiveness is limited as the virus mutates and develops resistance to the drugs over time.

Primary function of sex is not to promote diversity, but to maintain a species' identity

Biology textbooks maintain that the main function of sex is to promote genetic diversity. But Henry Heng, Ph.D., associate professor in WSU's Center for Molecular Medicine and Genetics, says that's not the case.

New biological insights into fat tissue

For better or worse, a popular class of anti-diabetic drugs does more than lower blood sugar. One known as rosiglitazone has been in the spotlight for its possible link to increased cardiovascular events, but it also seems to come with unexplained vascular benefits and an unwelcome tendency for weight gain.

Men better than women at visuo-spatial and auditory-spatial tasks

Differences in male and female behaviour are often subject to study. Women are known to be more verbally fluent, have better manual dexterity and are better at noticing things (like a new haircut). Men on the other hand often take less time parking their cars and have less trouble than women in navigating in a new city.

Researchers develop way to uncover evolution of human cancer cells

A team of researchers led by scientists at the University of California, San Francisco has developed a way to uncover the evolution of human cancer cells, determining the order in which mutations emerge in them as they wend their way from a normal, healthy state into invasive, malignant masses.
