...y high," Dr. Szerlip says. "Anywhere from 50 to 70 percent of those patients die and over the past 20 years, despite dialysis, that has not changed much." He hopes the new device, developed by Dr. H. David Humes at the University of Michigan, can help turn the tide for some patients by more closely mimickin...

Man and mouse share genome structures

...romosomes, numbers 21 and 22, containing about two percent of the human genome. They also sampled additional regions in both the human and mouse genomes, finding similar patterns along equivalent chromosomal regions, even where the underlying DNA sequences are different. Bernstein and Schreiber began to dev...

Molecular biology fills gaps in knowledge of bat evolution

...ecord alone left bat evolutionary history about 61 percent incomplete, according to Springer. Bats play a major ecological role as plant pollinators and insect predators. For Springer, this latest research is significant because it shows that molecular information can contribute to resolving and illuminatin...

UCSB scientists probe sea floor venting to gain understanding of early life on Earth

The flanks are deeper than the mid-ocean ridge crest. Cooling of the tectonic plates, and the impact of the ridge flank syst...

That's because it didn't sequence genes belonging to the vast communities of bacteria that normally live on and in us. Now a $1.45 million grant from the W.M.
