Study identifies gene in mice that may control risk-taking behavior in humans

... people react the way they do to fear, or why they take risks, Olson said. "The question is, are there differences in the neuroD2 gene-coding sequence or differences downstream of the neuroD2 pathway during brain development that could affect either psychiatric or emotional functions in humans? It's a com...

Structures of marine toxins provide insight into their effectiveness as cancer drugs

..." he says. "Scientists who study natural products take their cues from what nature has already done. We're adding deep biochemical meaning to this area." He adds that synthetic chemists hope that actin-based drugs might one day rival the success of Taxol, a powerful drug derived from a natural product ...

Discovery suggests why stem cells run through stop signs

... microRNAs are necessary for stem cell division to take place, suggesting that microRNAs shut off the signals that stop cell division in most other cells. The findings were published online this week by the journal Nature. In the paper, the researchers also speculate that microRNAs may play a similar rol...

Past droughts geographically widespread in the West, according to tree-ring data

...'s second phase, which will begin this month, will take a closer look at more recent history when scientists from the tree-ring lab will re-core trees in the Salt and Verde watersheds to gather new data from the last 40 years, a period when the watersheds have experienced both record wet and record dry ep...

Why do aneurysms form? New studies suggest leading role for white blood cells

..., new ideas about why aneurysms form have begun to take shape. "We're finding that in general, an aneurysm is an inadequate response to injury," Upchurch explains. "Something happens to damage elastin fibers in the blood vessel wall and, for some reason, the immune system's normal healing response doesn't...
