(Santa Barbara, Calif.) –– Fire must be accounted for as an integral part of climate change, according to 22 authors of an article published in the April 24 issue of the journal Science. The authors determined that intentional deforestation fires alone contribute up to one-fifth of the human-caused increase in emissions of carbon dioxide, a heat-trapping gas that raises global temperature.

CHAMPAIGN, Ill. — Researchers report today that they have sequenced the bovine genome, for the first time revealing the genetic features that distinguish cattle from humans and other mammals.

The six-year effort involved an international consortium of researchers and is the first full genome sequence of any ruminant species. Ruminants are distinctive in that they have a four-chambered stomach that – with the aid of a multitude of resident microbes – allows them to digest low quality forage such as grass.
