Terra spacecraft and ER-2 aircraft begin study of Southern Africa's environment
The NASA Terra spacecraft and ER-2 aircraft conducted the first synchronized scientific observations over Southern Africa as part of the six-week SAFARI 2000 initiative. The target was to measure carbon monoxide levels in the atmosphere, a major component of air pollution.
Michigan researchers receive national award
The Ovshinskys will be designated one of 12 Heroes of Chemistry by the American Chemical Society for their development of better batteries for electric cars and roof shingles that convert sunlight to electricity. They are also working on making use of hydrogen as fuel practical and affordable.
Creeping reduces quake risk on Berkeley fault, sayScienceauthors
A new model of the northern Hayward Fault in California's San Francisco Bay Area suggests that a major earthquake along that portion of the fault may be less likely than previously suspected. Aseismic creep has been relieving strain on the northern part of the fault, making a large earthquake on this segment unlikely.
The ultimate pocket protector--radiation detection made easy
A dosimeter, a portable device, detects gamma rays and neutrons to ensure workplace safety in nuclear power plants and research labs. It uses lithium isotopes to measure neutron particles and has been recognized as one of the 100 most significant technological achievements for the year 2000.
Treatment could help thousands who experience blockage after angioplasty procedure
Researchers at Penn State have developed a procedure that virtually eliminates tissue growth and subsequent blockages after angioplasty, reducing the risk by 90%. The ceramide-coated balloon catheters inhibit vascular smooth muscle cell growth, preventing arterial obstruction.
Ohio researcher receives national award
M. David Francis, an Ohio-based physical biochemist, received a national award from the American Chemical Society for his pioneering work on fluoride additives in toothpaste and pharmaceuticals.
Pittsburgh researcher receives national award
Raman Venkatesh, a chemical engineer from Pittsburgh, has developed a self-contained system called ISEP that removes perchlorate and nitrate from drinking water. The technology is cost-effective, safe, and fits into existing water-treatment plants, improving access to clean drinking water for communities.
Hopkins researchers uncover new information about tumor angiogenesis
The study identified 46 genes overexpressed in tumor endothelium, up to ten fold, and 33 genes expressed at significantly lower levels, revealing a different environment for tumor growth. The researchers believe endothelial cells are promising therapeutic targets to halt cancer cell growth.
New Jersey researchers receive national award
In 1975, medicinal chemists Miguel A. Ondetti and David W. Cushman designed captopril, the first of an innovative class of drugs controlling high blood pressure and heart disease.
Genetic program builds the pipeline that nourishes tumor growth
A genetic program has been identified that constructs the pipeline supplying blood and nutrients to colorectal tumors. This program involves a group of 46 genes known as tumor endothelial markers (TEMs), which are elevated tenfold or more in tumor endothelium.
Connecticut researchers receive national award
Two Connecticut chemists and their Croatian colleagues have been honored by the American Chemical Society for discovering a new and unusual kind of antibiotic. The team's work on azithromycin has led to the development of a commercially viable oral antibiotic that kills a broad spectrum of microbes, including those causing chlamydia.
Gigantic new telescope to unlock secrets of the universe
The Green Bank Telescope (GBT) is the world's largest fully steerable radio telescope, opening a new era of astronomical research. With its record-breaking capabilities, scientists will be able to study the universe in unprecedented detail, making groundbreaking discoveries and advancing our understanding of the cosmos.
Swiss research team receives American award
A Swiss research team led by Peter Buehlmayer has discovered valsartan, a drug controlling high blood pressure without side effects. The team's work has improved the lives of millions worldwide, offering hope for those affected by hypertension.
New conserve water educators guide now available
Montana State University has released a new Conserve Water Educators Guide to help inform others about basic water science topics with a focus on water conservation. The guide provides contemporary materials for educators, water managers, and community leaders to educate the public about water conservation.
Webster research team receives national award
Damodar Pai, John Yanus, and Milan Stolka developed a new photoconductor made from small molecules that turns light into an electrically charged template with near-perfect efficiency. Their innovation led to practical commercial devices for home and office use, making laser printers more durable and affordable.
