Or, if a toxic metal, such as lead or arsenic, is bound to the surface of the goe......, a second goal has been to learn whether virus is shed specifically into genital and oral fluids during early infections because those fluids are the primary vehicles of sexual transmission of HIV, he said.

Roth's studies on biological limbo may shed light on two problems that perplex cancer biologists: the control of stem-cell division and how oxygen deprivation affects tumor growth.

...B homolog in a simple green algae, scientists have shed a surprising new light on the potential role of RB-like proteins in the plant cell cycle. The retinoblastoma protein (RB) is an intensely studied protein, owing to its role as a tumor suppressor in humans.
