Researchers at Oak Ridge National Laboratory created a computer model of the Ford Explorer to simulate 35 mile per hour crash tests. The model will provide information used to assure future, lighter vehicles meet safety requirements, reducing the need for expensive actual crashes.
A team of NASA scientists disagrees with a recent study suggesting that satellite data shows no warming trend in the Earth's lower atmosphere, while surface temperature data shows a +0.12 deg C/decade increase. The disagreement is largely due to differences between satellite and surface measurements over oceans versus land areas.
Researchers have found that cidofovir, a new antiviral drug, can slow the progression of cytomegalovirus (CMV) retinitis, a common cause of vision loss and blindness in AIDS patients. The study showed that both low and high doses of the drug were effective, allowing for less frequent treatment compared to traditional options.
A team of scientists from NCAR analyzed global temperature trends obtained via satellites and surface instruments. They found that satellite data can produce spurious drops due to changes in satellite records, which can mask actual rises in global temperatures.
