Don't stand so close to me: A new view on how species coexist
...hing else. So it is with any other species. Now we know
that they coexist precisely because they each have different life histories." The London researchers assembled a simple artificial community of parasitoid wasps within a computer model, and then watched what happened over very long periods of time - ...

that we had physical contact with another species of human. We either battled with them, or lived with them or even mated with them. Regardless, we touched them, and that is pretty dramatic to think about." Reed wonders if contact with our ...

HHMI researchers Richard Axel and Linda Buck win 2004 Nobel Prize
... Their efforts produced nothing at first. "Now we know
why our initial schemes failed," said Axel. "It's because there are a large number of odorant receptors, and each was expressed only at a very low level." Finally, Buck came up with what Axel calls "an extremely clever twist." She made three assumpti...

now that most diseases involve proteins going wrong in one of two ways," said lead researcher Cecilia Clementi, assistant professor of chemistry at Rice University. "In the first, proteins don't function correctly because they fold into the wrong sha...
