"We have DEET, but it has to be reapplied, you use large amounts, and every part of the skin has to be covered. It can't be used for infants or toddlers beca...

Steckel cites several possible reasons why height declined toward the end of the Middle Ages: The climate changed rather dramatically in the 1300s, when the Little Ice Age triggered a cooling trend that wreaked havoc on northern E...

"The mice give us a highly reproducible glimpse at the earliest forms of cancer those rarely seen in the clinic and therefore can be used to develop new markers for detection as well as new strategies for prevention a...

"This is really the next stage in human genome research," says Whitehead Member Richard Young, who headed the project together with Whitehead Fellow Ernest Fraenkel and MIT Computer Scientist David Gifford. Key to understanding how the genome is controlled are gene...

After hearing the whole bizarre story of the glowing squid, his immediate response was that it sounded like a scene from a James Bond film. That was it James Pond was born and it was then a race aga...

Further, the team found that the way ginseng extracts are processed can also alter the compositional ratio. "This is a ve...

"I didn't really think that this would work, because it seemed unlikely that, since pathogenicity seemed to be such a complex process, one factor could have such a dramatic effect by itself," he said. In further experiments, the researchers found that when they remov...

At this point, the researchers stepped back and looked more broadly at the gene and flanking regions of the chromosome. They identified a total of 36 S...
