A global evolutionary map reveals new insights into our last common ancestor

In 1870 the German scientist Ernst Haeckel mapped the evolutionary relationships of plants and animals in the first ’tree of life’. Since then scientists have continuously redrawn and expanded the tree adding microorganisms and using modern molecular data, yet, many parts of the tree have remained unclear. Now a group at the European Molecular Biology Laboratory (EMBL) in Heidelberg has developed a c

Ocean FOCUS began issuing forecasts on 16 February 2006 – just in time to warn oil production operators of a new warm eddy that has formed in the oil and gas-producing region of the Gulf of Mexico.

These eddies, similar to underwater hurricanes, spin off the Loop Current – an intrusion of warm surface water that flows northward from the Caribbean Sea through the Yucatan Strait – from the Gulf Stream and can cause extensive and costly damage to underwater equipment due to the extensive deep

Scientists have completed an extensive study of more than 3,000 patients who received a promising anti-inflammatory drug, natalizumab, that was linked to three cases of a serious brain infection in large clinical trials halted in early 2005.

The new study found no new cases of progressive multifocal leukoencephalopathy (PML) and confirmed the three previously identified cases of PML associated with use of the drug. One fatal and one nonfatal case of PML occurred in a trial us

Scientists from NASA and Columbia University, New York, have used computer modeling to successfully reproduce an abrupt climate change that took place 8,200 years ago. At that time, the beginning of the current warm period, climate changes were caused by a massive flood of freshwater into the North Atlantic Ocean.

This work is the first to consistently recreate the event by computer modeling, and the first time that the model results have been confirmed by comparison to the climate rec

Since its launch in 2002, Envisat, the world’s largest and most sophisticated satellite ever built, has been providing scientists and operational users with invaluable data for global monitoring and forecasting – and the future looks even brighter.

“The Envisat mission has reached its full maturity with the services provided by the satellite now well established, and the scientific results based on its data being increasing published,” Envisat Mission Manager Henri Laur said. (For m

A Purdue University researcher and his team have used improved satellite imaging and powerful computer modeling to more accurately forecast the likelihood and intensity of storms and tornados.

The key to the new weather prediction model is its more precise simulation of the amount of moisture surface vegetation is releasing into the upper atmosphere to affect the weather conditions, said Dev Niyogi (pronounced Dave Knee-yoo-gee), an assistant professor of agronomy and earth and at
