Cambridge, UK (SPX) Nov 04, 2004Antarctic whales, seals and penguins could be threatened by food shortages in the Southern Ocean. Numbers of Antarctic krill (Euphausia superba), a shrimp-like crustacean at the heart of the food chain, are declining. The most likely explanation is a dramatic decline in sea-ice. The results are published this week in the journal Nature. Is Shiva Another K-T Impact Zone From 65 Million Years Ago 
Moffett Field CA (SPX) Nov 04, 2004According to the Earth Impact Database, there are two craters - the 180 kilometer-wide Chicxulub crater in Yucatan, Mexico and the much smaller Boltysh crater in eastern Ukraine - that date back to the Cretaceous-Tertiary (K-T) extinction 65 million years ago. |

Ecosystem Remodelling Among Vertebrates During Permian-Triassic Extinction
Bristol, UK (SPX) Nov 04, 2004The biggest mass extinction of all time happened 251 million years ago, at the Permian-Triassic boundary. Virtually all of life was wiped out, but the pattern of how life was killed off on land has been mysterious until now. A team from Bristol University and Saratov University, Russia, have now laid the evidence bare. Tiger Workshop Puts Focus On Space For African Water Management 
Pretoria, South Africa (ESA) Nov 04, 2004A TIGER Initiative offer to make ESA satellite data available for monitoring African water resources sparked an enthusiastic take-up by researchers across the continent, and beyond it. Some 95 proposals have been received, 65 of which are accepted for discussion during next week's annual TIGER Workshop in Pretoria, South Africa. Arctic Ice To Melt This Century Unless Greenhouse Gases Curbed: Report 
Oslo (AFP) Nov 02, 2004The Arctic ice cover will completely disappear in summer by the end of this century unless carbon dioxide emissions are significantly reduced, according to a scientific study to be released next week. The Left-Handed Lobster 
Moffett Field CA (SPX) Nov 03, 2004Did that lobster on your dinner plate inherit its big crusher claw .. or did it evolve through need, without the help of genes? Genetics aren't the only triggers for the traits a species develops, according to findings from a University of Alberta professor. The research challenges the classical Darwinian theory of evolution as being the sole explanation for how new life forms arise. Were Volcanoes The Crucible Of Life 
Cambridge UK (SPX) Nov 02, 2004New research by scientists at the Universities of Cambridge and Birmingham shows that volcanoes produce large quantities of biologically available nitrogen. Life on Earth needs nitrogen to survive, but little is known about how it became available to the earliest organisms. The research suggests that volcanoes may have fertilised the advent of life on the early Earth. Tracking Ancient Earth's Oxygen Levels Provides Backdrop for Evolution 
Columbia MO (SPX) Nov 02, 2004Geologists have long considered sulfate, a common salt dissolved in seawater, as the key to determining how and when life evolved. On the ancient Earth, acquiring enough ocean sulfate measurements to accurately define the ecological conditions during evolution has been a serious challenge. China's Biggest Freshwater Lake Shrinks By 600sq Km 
Nanchang (XNA) Nov 02, 2004China's biggest freshwater Poyang Lake is reported shrinking its water space by more than 600 square kilometers due to severe dry spells in eastern Jiangxi province this October. |

St Louis MO (SPX) Nov 01, 2004To operate a nuclear power plant like Three Mile Island, hundreds of highly trained employees must work in concert to generate power from safe fission, all the while containing dangerous nuclear wastes. Now, Researchers at Washington University in St. Louis have analyzed the isotopic structure of noble gases produced in fission in a sample from the only known natural nuclear chain reaction site in the world in Gabon, West Africa, and have found how she does the trick. Darwin's Greatest Challenge Tackled: The Mystery Of Eye Evolution 
Heidelberg, Germany (SPX) Oct 29, 2004When Darwin's skeptics attack his theory of evolution, they often focus on the eye. Darwin himself confessed that it was "absurd" to propose that the human eye evolved through spontaneous mutation and natural selection. New Human Species Found On Indonesian Island Of Flores 
Paris (AFP) Oct 28, 2004In one of the most spectacular fossil finds in decades, anthropologists are to announce on Thursday they have found the bones of a tiny human who may have been a twig in mankind's family tree. Measuring Dolphin Brains Over 47 Million Years 
Moffett Field CA (SPX) Oct 28, 2004The intelligence and cognitive capabilities of dolphins and their aquatic cousins have long fascinated the public and the scientific community, but the question of how and why they have such large brains has mostly gone unanswered. |
