These findings suggest that the reduction of blood pressure with IHG may be due to improvements of endothelial function....

Component of volcanic gas may have played a significant role in the origins of life on Earth

... The question of the origins of life is: what came before the stromatolites? Research on the origins of life has suggested the notion of an ancient RNA world--one in which RNA genes stored genetic information (something done by DNA today), carried out the chemistry necessary for life, and formed the ess...

Study describes basic mechanism in cell growth control involving damaged DNA

...n, CDT1 must be degraded to prevent re-replication before the cell finishes dividing. "And when DNA is damaged, the cell must find a way to very rapidly degrade CDT1 to prevent continued replication. And that job is carried out by the ubiquitin ligases."
