Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St. Louis have shown. The finding is an important step toward developing a vaginal gel that may prevent the spread of HIV, the virus that causes AIDS.

A team of geneticists has announced that they have successfully bred fruit flies with the capacity to count. After repeatedly subjecting fruit flies to a stimulus designed to teach numerical skills, the evolutionary geneticists finally hit on a generation of flies that could count -- it took 40 tries before the species' evolution occurred. The findings, announced at the First Joint Congress on Evolutionary Biology in Canada, could lead to a better understanding of how we process numbers and the genetics behind dyscalculia -- a learning disability that affects a person's ability to count and do basic arithmetic. "The obvious next step is to see how [the flies'] neuro-architecture has changed," said geneticist Tristan Long, of Canada's Wilfrid Laurier University, who admits far more research is needed to delve into what the results actually mean.

Get Set: A Jet To Replace Needles For Injections : Shots - Health Blog
The needle and syringe are icons of modern medicine. But a device developed at MIT to squirt medicines quickly and pretty much painlessly through the skin suggests that the future of medicine could be needle-free.

(Phys.org) -- A materials scientist at Michigan Technological University has discovered a chemical reaction that not only eats up the greenhouse gas carbon dioxide, it also creates something useful. And, by the way, it releases energy.

Sugar makes you stupid: Study shows high-fructose diet sabotages learning, memory
Attention, college students cramming between midterms and finals: Binging on soda and sweets for as little as six weeks may make you stupid. A new UCLA rat study is the first to show how a diet steadily high in fructose slows the brain , hampering memory and learning — and how omega-3 fatty acids can counteract the disruption. The peer-reviewed Journal of Physiology publishes the findings in its May 15 edition.

In June of 1939, a petite Chicago pediatrician strode to the dais of Montréal's Windsor hotel and recounted to those attending the CMA's 70th annual meeting the results of what is likely the world's longest, most detailed and most ambitious dietary experiment.

One of the most instantly recognizable features of glass is the way it reflects light. But a new way of creating surface textures on glass, developed by researchers at MIT, virtually eliminates reflections, producing glass that is almost unrecognizable because of its absence of glare — and whose surface causes water droplets to bounce right off, like tiny rubber balls. The new “multifunctional” glass, based on surface nanotextures that produce an array of conical features, is self-cleaning and resists fogging and glare, the researchers say.Safely Preserving Eggs |
