The presence of this parasite was a powerful predictor of the presence and frequency of malformed amphibians in an aquatic system.

This asymmetry could suggest that the rice genome is a "superset" of the Arabidopsis genome, the result of...Hebrew University research finds why chemotherapy might lead to cancer

"What's so striking about the klotho variant is that it is relatively common and has its effect by age 65," explains Dan Arking, Ph.D., who conducted the klotho study as part of his doctoral work with Dietz.

They found a striking likeness between its sequence and that of the Moloney murine leukemia virus envelope protein, a protein located on the membrane of the leukemia virus. Envelope proteins allow the virus to bind to a host cell and promote the fusion of the virus and ce...Healy researchers make a series of striking discoveries about Arctic Ocean

A UCSF-led team is reporting striking results in mice that indicate that a molecule known as HIF-1α could prove an effective target for inducing the growth of blood vessels in oxygen-starved tissues. The strategy is sought for treating cardiac and peripheral vascular disease, diabe...Global warming more common than thought, deep-sea drilling off Japan now demonstrates
