But their technique could already be obsolete. Another team headed by Yuri Verlinsky of the Reproductive Genetics Institute, based in Chicago, claims to have produced patient-matched embryonic stem cells without reso...The first, high resolution continuous record of oxygen concentration in the earth's atmosphere shows that a sharp rise in oxygen about 50 million years ago gave mammals the evolutionary boost they needed to dominate the planet, according to Paul Falkowski, Rutgers professor of marine science and lead author of a paper published Sept. 30 in the journal Science. . Falkowski and his colleagues hav...
