Scripps research scientists solve structure of a critical innate immune system protein

...r been seen before, an essential step toward fully understanding the critical role this protein--and other TLRs--play in the human innate immune system to rapidly detect invading pathogens. "We don't know functionally how TLR proteins work," says Professor Ian Wilson, D.Phil., who is a professor in the Department...

Bees, Brains and Addiction

... neurobiologists like himself are gaining a better understanding of human addiction by examining simpler brains, such as those of bees. Bees learn to land on a tile of a certain color after they are rewarded just once with sugar water for landing on that color. A single nerve cell in a bee's brain, Sejnowski expl...

Novel compounds show promise as safer, more potent insecticides

...and that these receptors may help provide a better understanding of their role in calcium signaling, which could lead to new insights into human diseases. The American Chemical Society is a nonprofit organization, chartered by the U.S. Congress, with a multidisciplinary membership of more than 158,000 chemists an...

Tufts researchers shine light on firefly mysteries

...ard, such research may ultimately help further our understanding of human communication, signal evolution, and biomedicine. In previous research published in 2003, Lewis and her then-doctoral student Christopher Cratsley found that female fireflies of one species (Photinus ignitus) are strongly attracted to males...

Novel plague virulence factor identified

The shorter time and increased ease of experimentation can be especially important, the researchers continued, given potential use of Y. pestis as a biological weapon, they said. The results of the Duke research will appear A...

Unraveling a stomach cancer puzzle

... has made several substantial contributions to the understanding of Stat3, the protein linking those 'genes behaving badly' and central to development, tissue equilibrium and the immune system. "We showed that, in mice, hyperactive Stat3 shuts down a vital controller of stomach cell growth, called TGF beta, and th...

We're a long way from understanding why we're so different from our closest primate cousins, but this study provides plenty of tools, and hypotheses, to mine the tiny differences in our DNA for more clues. ### Citation: Nielsen R, Bustamante C, Clark AG, Glanowski S, Sackton TB, et a...

Bumblebees copy one another when contending with unfamiliar flowers

... findings that offer a surprising new twist to our understanding of how bumblebees, a vital floral pollinator, select the flowers from which they collect nectar. When faced with unfamiliar plants, foraging bees do not choose flowers entirely alone but instead copy the choices of other bees. The new findings sugges...
