Bloomington - Feb 18, 2004The recent marriage of evolutionary biology with developmental biology has resulted in the birth of a new field, evolutionary developmental biology, or "evo-devo." Open-Air Experiment Could Deflate Hopes Forests Will Alleviate Global Warming 
Seattle - Feb 16, 2004A futuristic Duke University simulation of forest growth under the carbon dioxide-enriched atmosphere expected by 2050 does not reinforce the optimism of those who believe trees can absorb that extra CO2 by growing faster, said a spokesman for the experiment. |

The Role Of Gas Hydrates In Carbon Cycling And Environmental Change
Houston - Feb 16, 2004 As mankind pumps more and more carbon into the atmosphere, those studying global climate change are becoming increasingly interested in the fate and consequences of all that extra carbon. At the same time, new findings about poorly understood compounds called clathrate hydrates � ice-like substances formed by water, methane and other gases located just beneath the ocean floor � show that science has long oversimplified the processes of carbon cycling on Earth. Carbon Fertilization May Be Flimsy Weapon Against Warming
Seattle - Feb 16, 2004A growing body of evidence questions calculations by the Intergovernmental Panel on Climate Change that the land will automatically provide a significant, long-term carbon "sink" to offset some of the effects of greenhouse gas emissions. Human Evolution At The Crossroads: Integrating Genetics And Paleontology 
Seattle - Feb 16, 2004Advances in genetics during the last decade not only have influenced modern medicine, they also have changed how human evolution is studied, says an anthropologist from the University of Illinois at Urbana-Champaign. Intelligent Design: The New 'Big Tent' For Evolution's Critics
Seattle - Feb 16, 2004Since the advent of Darwinism in the mid-19th century, a variety of movements have jousted for the intellectual high ground in the epic evolution versus creationism debate. At one end of the spectrum reside the "naturalistic evolutionists" who argue that life neither requires nor benefits from a divine creator. Astronomers Unravel A Mystery From The Dark Ages 
Cardiff - Feb 11, 2004Scientists at Cardiff University, UK, believe they have discovered the cause of crop failures and summer frosts some 1,500 years ago � a comet colliding with Earth. The team has been studying evidence from tree rings, which suggests that the Earth underwent a series of very cold summers around 536-540 AD, indicating an effect rather like a nuclear winter. Researchers Pinpoint Brain Areas That Process Reality, Illusion
by Tony FitzpatrickSt. Louis - Feb 11, 2004 Marvin Gaye wailed in the '60s hit "Heard it through the Grapevine" that we're supposed to believe just half of what we see. Biomedical engineer Daniel Moran, Ph.D., and University of Pittsburgh researchers, have identified areas of the brain where reality and illusion are processed. Researchers Determine Reason For Deadly Spread Of 1918 Influenza 
Chevy Chase - Feb 11, 2004The explosive spread of the influenza virus during the 1918 pandemic that killed some 20 million people worldwide was likely enabled by the unique structure of a protein on the virus's surface, researchers are reporting. The newly determined structure of the viral protein reveals that the 1918 strain of influenza underwent subtle alterations that enabled it to bind with deadly efficiency to human cells, while retaining the basic properties of the avian virus from which it evolved. |
Dinosaur Fossil Record Points To 500 Plus Undiscovered Speciess
by Tony FitzpatrickSt. Louis - Feb 11, 2004 A graduate student in earth and planetary sciences in Arts & Sciences at Washington University in St. Louis has combed the dinosaur fossil record from T. Rex to songbirds and has compiled the first quantitative analysis of the quality and congruence of that record. Comets Spread Earth-Life Around Galaxy, Say Scientists 
Cardiff - Feb 11, 2004If comets hitting the Earth could cause ecological disasters, including extinctions of species and climate change, they could also disperse Earth-life to the most distant parts of the Galaxy. It's A Stirring Tale Of Bacterias
by Mari N. JensenTucson - Feb 11, 2004 Poetry in motion are not words usually applied to bacteria. But when researchers at the University of Arizona looked into a petri dish, that's what they saw. Groups of bacteria streamed through the fluid, creating an ever-changing pattern of swirls and blips visible to naked eye. In a bacterial ballet, the tiny organisms seemed to be moving through the fluid of the dish in coordinated fashion, almost like flocking in birds or schooling in fish. San Diego Unveils Pilot Project For Automated Monitoring Of Animal Behavior
San Diego - Feb 11, 2004Computer scientists and animal care experts at the University of California, San Diego (UCSD) have come up with a new way to automate the monitoring of mice and other animals in laboratory research. Columbia To Establish Government Biological Information Site
New York - Feb 11, 2004Columbia University Senior Research Scientist Robert Worrest, who will direct the development of the new NBII northeast information node, has more than 25 years of ecological research and assessment experience related to environmental change and variability. Scientists Report First Sequencing Of Environmental Genome
Berkeley - Feb 11, 2004In the first triumph of a field dubbed "environmental genomics," scientists at the University of California, Berkeley, in collaboration with the Joint Genome Institute, have for the first time sequenced the genomes of the most abundant members of a community of organisms - not one at a time, but simultaneously. Pollution Might Be Main Cause Of Most Coral Reef Die Off 
Harbor Branch - Feb 11, 2004Scientists agree that coral reefs are in an alarming global state of decline. However, determining the main cause or causes of this decline has proven a much more contentious issue. |
