A first draft of the "tree of life" for the roughly 2.3 million named species of animals, plants, fungi and microbes has been released, and two University of Michigan biologists played a key role in i...
Melting of glacial ice will probably raise the sea level around the globe, but how fast this melting will happen is uncertain. Greenland is especially pivotal in the study of melting ice sheets and ri...
TRAF-interacting protein, an inhibitor of the canonical nuclear factor-kappaB pathway, plays a key role in the estradiol -dependent apoptosis of the dual-phenotype gamma amino butyric acid/glutamate neurons in the anteroventral periventricular nucleus of the male rat
