Moist Soil Hot Spots May Affect Rainfall![]() While the Earth is moistened by rainfall, scientists believe that the water in soil can, in turn, influence rainfall both regionally and globally. Forecasters, water resource managers and farmers may benefit once this connection is better understood. Modeling Ocean Behavior: The Key To Understanding Our Future Climate ![]() Scientists have long recognized the importance of oceans in our climate. In fact, the unique physical characteristics of our oceans are largely responsible for making the Earth a livable environment. Greenland Ice Core Project Yields Probable Ancient Plant Remains ![]() A team of international researchers working on the North Greenland Ice Core Project recently recovered what appear to be plant remnants nearly two miles below the surface between the bottom of the glacial ice and the bedrock. India To Launch Recoverable Spacecraft In 2005 ![]() India will join an elite club of countries with the launch next year of its first recoverable and reusable spacecraft in polar orbit, the Indo-Asian News Service (IANS) reported last Friday (August 13). Science More Creative And Less "True" Than Many Believe ![]() Science is not just evidence, but intuition. It is not just procedures, but creativity. Its conclusions are not set in stone, but ever-changing and open to question as part of a dynamic social enterprise. Evolvability Could Be A Driving Force In Drug Resistance ![]() Not only has life evolved, but life has evolved to evolve. That's the conclusion drawn by two Rice University scientists who have designed a computer simulation to test the idea that evolvability - the likelihood of genetic mutation - is a trait that can itself be favored or disfavored through the process of natural selection. Whale Carcass Yields Bone-Devouring Worms ![]() Scientists studying a whale carcass in Monterey Canyon recently announced the discovery of two new species of unique worms that feed on the bones of dead whales. In the July 30 issue of Science, the researchers describe these worms, whose bodies and feeding strategies differ from those of any other known animal. |
Plant Gene Discovery Could Reduce Fertilizer Needs And Phosphate Pollution![]() Scientists at the Boyce Thompson Institute for Plant Research at Cornell University have uncovered the genes that enable plants to interact with beneficial soil dwelling fungi and to access phosphate delivered to the roots by these fungi. Cluster Spacecraft Catch Crashing Waves In Earth's Magnetic Bubble ![]() A bevy of satellites buzzing around in the Earth's magnetosphere has found at least part of the answer to a long-standing puzzle about the source of the charged particles that feed the aurora. Technology Already Exists To Stabilize Global Warming ![]() Existing technologies could stop the escalation of global warming for 50 years and work on implementing them can begin immediately, according to an analysis by Princeton University scientists. India To Launch Education Satellite Mid-September ![]() India has scheduled the launch of Edusat, the satellite dedicated to beam educational programs, for mid-September, the Indo-Asian News Service (IANS) reported Thursday. The Olympics On Animal Planet ![]() In part IV of this Olympic series, the question of how humans might compete against other species is considered. Are we so sure in our pride as a species, that our champions are the same as the planet's winners? How Topography Affects The Gulf Stream's Path ![]() Scientists have been studying the Gulf Stream in the North Atlantic Ocean for centuries but still do not completely understand the swiftly moving current's physical dynamics. One mysterious phenomenon is the path of the Gulf Stream, which does not follow a straight line, but bends, meanders, and changes from day to day. Growing Pains: T. Rex Was Teenage Giant ![]() Most teenagers have growing pains, but none probably compared to those of Tyrannosaurus rex as it ascended to adulthood more than 65 million years ago, according to a Florida State University researcher. |
