New York - Jan 29, 2004In the most recent and mathematically rigorous study to date determining whether Neanderthals contributed to the evolution of modern humans, a team of anthropologists examining the skulls of modern humans and Neanderthals as well as 11 existing species of non-human primates found strong evidence that Neanderthals differ so greatly from Homo sapiens as to constitute a different species. Cosmic Rays Are Not The Cause Of Climate Change, Scientists Say 
WASHINGTON - Jan 27, 2004Eleven Earth and space scientists say that a recent paper attributing most climate change on Earth to cosmic rays is incorrect and based on questionable methodology. Writing in the January 27 issue of Eos, published by the American Geophysical Union, Stefan Rahmstorf of the Potsdam Institute for Climate Impact Research and colleagues in Canada, France, Germany, Switzerland, and the United States challenge the cosmic ray hypothesis. |

Sediment Samples Show How Plants Would Fare In Hotter, Drier Future
Champaign - Jan 21, 2004Sediment samples dating back thousands of years and taken from under the deep water of West Olaf Lake in Minnesota have revealed an unexpected climate indicator that can be factored into future projections. Study Pinpointing Origins Of Siberian Peat Bogs Raises Concerns 
Arlington - Jan 21, 2004Massive Siberian peat bogs, widely known as the permanently frozen home of untold kilometers of moss and uncountable hordes of mosquitoes, also are huge repositories for gases that are thought to play an important role in the Earth's climate balance, according to newly published research by a team of U.S. and Russian scientists in the Jan. 16 edition of the journal Science. Gene May Be Key To Evolution Of Larger Human Brain 
Chevy Chase - Jan 21, 2004Howard Hughes Medical Institute researchers have identified a gene that appears to have played a role in the expansion of the human brain's cerebral cortex -- a hallmark of the evolution of humans from other primates. A "Hot Tower" Above The Eye Can Make Hurricanes Stronger 
Greenbelt - Jan 21, 2004They are called hurricanes in the Atlantic, typhoons in the West Pacific, and tropical cyclones worldwide; but wherever these storms roam, the forces that determine their severity now are a little less mysterious. NASA scientists, using data from the Tropical Rainfall Measuring Mission (TRMM) satellite, have found "hot tower" clouds are associated with tropical cyclone intensification. High-Flying Montana Experiments Downed In Antarctica 
Bozeman - Jan 19, 2004Montana student experiments that were flying on a high-altitude balloon over Antarctica had to be brought down to prevent them from drifting out to sea, Michelle Larson, Deputy Director of the Montana Space Grant Consortium at Montana State University-Bozeman, said Wednesday. Researchers Show Evolutionary Theory Adds Up 
Calgary - Jan 15, 2004All living plants and animals are likely derived from two primitive species of bacteria, a mathematics professor at the University of Alberta has shown. Dr. Peter Antonelli and a former post-doctoral student of his, Dr. Solange Rutz, used an original mathematical modeling system and software program to evaluate and compare the two main theories of biological evolution. Ocean Life Depends On Single Circulation Pattern In Southern Hemisphere 
Princeton - Jan 15, 2004A study has shown that marine life around the world is surprisingly dependent on a single ocean circulation pattern in the Southern Hemisphere where nutrient-rich water rises from the deep and spreads across the seas. |
Quakes Along Central San Andreas Fault Peak Every Three-Years
Berkeley - Jan 12, 2004Medium to large earthquakes occurring along the central San Andreas Fault appear to cluster at regular three-year intervals - a previously unnoticed cycle that provides some hope for forecasting larger quakes along this and other California faults. El Nino-Related Fires Increase Greenhouse Gas Emissions 
Greenbelt - Jan 07, 2004Year-to-year changes in concentration of carbon dioxide and methane, two important greenhouse gases in the atmosphere, can be linked to fire activity associated with the El Nino-La Nina cycle, according to a study conducted by a team of NASA scientists and other researchers. Jeep Rescue - Unequalled, Unmatched, Ultimate Ability 
Auburn Hills - Jan 05, 2004Designed for the most extreme situations and unforgiving conditions, the Jeep Rescue concept is not only the ultimate type of search and rescue vehicle -- it's the ultimate execution of a Jeep off-road vehicle. Earth's Inconstant Magnetic Field 
Huntsville - Dec 30, 2003Every few years, scientist Larry Newitt of the Geological Survey of Canada goes hunting. He grabs his gloves, parka, a fancy compass, hops on a plane and flies out over the Canadian arctic. Not much stirs among the scattered islands and sea ice, but Newitt's prey is there--always moving, shifting, elusive. Solving The Ebola Enigma: Satellites Will Provide Clues 
Paris - Dec 30, 2003As a new outbreak of Ebola haemorrhagic fever strikes northwestern Congo, ESA is set to gather satellite data to help resolve the scientific enigma of this deadly disease. New Study Reports Large-scale Salinity Changes in the Oceans 
Woods Hole - Dec 19, 2003Tropical ocean waters have become dramatically saltier over the past 40 years, while oceans closer to Earth's poles have become fresher, scientists reported today in the journal Nature. Earth's warming surface may be intensifying evaporation over oceans in the low latitudes -- raising salinity concentrations there -- and transporting more fresh water vapor via the atmosphere toward Earth's poles. Extreme Weather And Climate Events Require Enhanced Action 
Geneva - Dec 18, 2003According to Prof. G.O.P. Obasi, Secretary-General of WMO, actions to achieve the objective of the United Nations Framework Convention on Climate Change (UNFCCC) are becoming increasingly urgent in view of the increasing concentration of greenhouse gases in the atmosphere, the continued rise in globally averaged surface temperatures, and a growing number of extreme weather and climate events, some of which are of unprecedented intensity. |
