"We've isolated for the first time what appears to be the true candidate stem cell," said Steindler, a neuroscientist and member of UF's Program of Stem Cell Biology and Regenerative Medicine. "There have been other candidates, but in...

The contaminants accumulate in their bodies and are released on land." The study took place at Cape Vera on no...

"The ocean is a very competitive environment, and these bacteria apparently won the race," said Stephen Giovannoni, an OSU professor of microbiology. "Our analysis of the SAR11 genome ...

Lands surface change on Alaska tundra creating longer, warmer summers in Arctic

...ospheric circulation patterns or to a reduction in sea ice in the summer or to an increase in cloud cover. The observed summer temperature increases are likely related to a global warming trend that has led to a longer snow-free season and an increase in the extent of woody vegetation. Both of these cha...

The red beard sponge (Microciona prolifera) has a cell-to-cell recognition system that, on a basic level, is similar to that of humans but much simpler....
