Some re-established elk herds lack genetic diversity of ancestors
...e geneticist. "Despite the fact that elk have been moved all over the United States, no one has looked at the effects of those reintroductions. These studies add to a growing body of literature that deals with reintroductions in general, and the genetic results of reintroductions of large animals." Elk onc...Plants' circadian clocks tune into latitude to enhance fitness

"When we determined day length in each of the latitudes for the plants, we found the correlation was highly significant between the circadian ...Explanation offered for Antarctica's 'blood falls'
...ons and his colleagues believe that as the glacier moved forward down through the valley, it captured some of the deposit and forced it up into the body of ice. Eventually, the deposit reached the margin, or edge, of the glacier and is being slowly pushed out or the ice. As the reddish, icy sludge melts at...Researchers define molecular basis of human 'sweet tooth'
..., Howard Hughes Medical Institute researchers have moved closer to understanding why some people cannot resist the impulses brought on by their sweet tooth. The researchers created mice with the same sweet-tooth preferences as humans by inserting the gene that codes for a human sweet-taste receptor protein...Duke researchers discover power behind molecular motors
... it was the first molecular motor of its kind that moved toward the more stable, or "minus" end of microtubules. The other kinesin motor proteins moved toward the fast-growing, or "plus" end. Endow previously showed that the normal Ncd motor moves only...Dartmouth study advances prion disease research
...ars, so research to piece together the process has moved slowly. The discovery more than a quarter century ago that prions were proteins, devoid of nucleic acids, upended what scientists assumed not only about disease transmission, but about life itself.
