...the team to create a system where multiple sensors placed around a wildfire will continuously send input such as temperature, wind direction and speed, and the moisture in grass and sticks to a high-end research computer known as a supercomputer. The supercomputer will use the mathematically based wildfire ...Study marks increased trends in infectious disease occurrences in our oceans
...study in recent years. With rising human stresses placed on the environment, understanding disease dynamics is vital to conserving marine ecosystems, warn the authors. Environmental factors such as global change could have complex effects on disease, and they recommended that future research look more clos...Oldest known evidence of cat taming found in Cyprus, researchers report in Science
...dicated someone had dug a small pit or grave, then placed the cat inside and rapidly covered it. Both skeletons are positioned symmetrically, with their heads to the west, though Vigne doesn't know if this was done intentionally. "I am not completely convinced that the common orientation of the skeletons m...Better techniques needed to predict earthquake hazards, UC study finds
..." To try to overcome this problem, the researchers placed several seismic monitoring stations at each campus in boreholes up to 100 meters (330 feet) deep three times the depth of typical geophysical studies and collected data on small earthquakes from local faults as well as regional seismic events. They...Scientists question reports of massive ant supercolonies in California and Europe
... ants taken from different nests often fought when placed side by side in an experimental vial. But in California, the scientists found that ants rarely engaged in combat, even if they were collected from nests hundreds of miles apart. Why would workers in Argentina exhibit intercolony aggression but...Physics tip sheet #41 - April 5, 2004

A source generated waves on one side of the cylinders, and the researchers observed the pattern of waves on the opposite side. At certain wave frequencies, negative refraction caused the waves to form...For the sake of land and climate, coaxing soil to soak up carbon

...m. "It inhibited viral growth, even at a low dose, placed minimal demands on the intracellular resources of the host cell and was effective when introduced either before or during the infection cycle." One other important finding, he adds, is that the strategy created no obvious way for the virus to develop...National Foundation For Cancer Research names UCSD's Webster Cavenee NFCR Fellow
