Scientists successfully grow ’dwarf belonging to the sea’ in laboratory

Scientists are now revisiting, and perhaps revising, their thinking about how Archaea, an ancient kingdom of single-celled microorganisms, are involved in maintaining the global balance of nitrogen and carbon. Researchers have discovered the first Archaea known to oxidize ammonia for energy and metabolize carbon dioxide by successfully growing the tentatively named, Nitrosopumilus maritimus, in the lab.

The impact of global warming on European weather patterns has been underestimated, according to a new report published in Nature this week.

Dr Gillett, of the University of East Anglia’s Climatic Research Unit, compared Northern Hemisphere air pressure changes at sea level over the past 50 years with predicted changes from nine state-of-the-art climate models.

The Northern Hemisphere Circulation study found that present climate change models – computer representations of

Scientists at the University of York have been awarded nearly £500,000 to help to establish a centre in the Atlantic Ocean to monitor gases in the atmosphere.

Dr Lucy Carpenter and Dr Alastair Lewis, of the University’s Department of Chemistry, have been awarded £487,070 by the National Environment Research Council (NERC) to set up an atmospheric observatory on the Cape Verde Islands.

The York chemists, who have been awarded the money under the NERC’s Surfa

In the wake of Hurricane Katrina — probably the greatest natural disaster in U.S. history — a leading ecologist says that one of the best things that could happen to New Orleans and the rest of southern Louisiana and Mississippi would be more rain.

“People might think I’m kidding, but I’m not,” said Dr. Seth R. Reice, associate professor of biology at the University of North Carolina at Chapel Hill’s College of Arts and Sciences.

“The floodwater still covering much

Scientists using satellite imagery found that at least 23 percent of the water released from the mouth of the Mississippi River from July through September 2004 traveled quite a distance – into the Gulf of Mexico, around the Florida Keys, and into the Atlantic Ocean.

The researchers combined data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra and Aqua satellites with information collected from ships to study the water discharge, appearing

The number of Category 4 and 5 hurricanes worldwide has nearly doubled over the past 35 years, even though the total number of hurricanes has dropped since the 1990s, according to a study by researchers at the Georgia Institute of Technology and the National Center for Atmospheric Research (NCAR). The shift occurred as global sea surface temperatures have increased over the same period. The research will appear in the September 16 issue of the journal Science, published by the AAAS, the science
