"What fruit flies teach us about RNA silencing" Phillip Zamore, Prof. of Biomedical Sciences, University of Mass..

All animals seem to have ways of exchanging information—monkeys vocalize complex messages, ants create scent trails to food, and fireflies light up their bellies to attract mates. Yet, despite the fact that nematodes, or roundworms, are among the most abundant animals on the planet, little is known about the way they network. Now, research led by Caltech biologists has shown that a wide range of nematodes communicate using a recently discovered class of chemical cues.

Using highly potent antibodies isolated from HIV-positive people, researchers have recently begun to identify ways to broadly neutralize the many possible subtypes of HIV. Now, a team led by biologists at Caltech has built upon one of these naturally occurring antibodies to create a stronger version they believe is a better candidate for clinical applications.
