(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.

Washington, DC—The most powerful earthquakes happen at the junction of two converging tectonic plates, where one plate is sliding (or subducting) beneath the other. Now a team of researchers, led by Teh-Ru Alex Song of the Carnegie Institution's Department of Terrestrial Magnetism, has found that an anomalous layer at the top of a subducting plate coincides with the locations of slow earthquakes and non-volcanic tremors. The presence of such a layer in similar settings elsewhere could point to other regions of slow quakes.

Scientists are tomorrow (24 April 2009) publishing the complete cattle genome in the journal Science. UK researchers, supported in part by the Biotechnology and Biological Sciences Research Council (BBSRC), have played a key part in the annotation and analysis of the genome as part of a 300-scientist collaboration, spanning 25 countries.

COLUMBIA, Mo. – A University of Missouri researcher worked with international teams to sequence the bovine genome and study the diversity among breeds. The research from the completed genome will provide new information about mammalian evolution, cattle genetics and could result in improved cattle production. The results appear this week in two articles in the journal Science.

An analysis of ancient Greenland ice suggests a spike in the greenhouse gas methane about 11,600 years ago originated from wetlands rather than the ocean floor or from permafrost, a finding that is good news according to the University of Colorado at Boulder scientist who led the study.
