Researchers found high concentrations of tolyltriazoles in groundwater under an airport, causing toxicity to bacteria and aquatic life. Current regulations only monitor glycol levels, ignoring major sources of toxicity.
The UCSF report reveals significant variations in cardiovascular risk factors among different ethnic/racial groups and regions in California. High blood pressure and diabetes rates are disproportionately affecting African Americans and Hispanics, with 41.5% of African American men and 35% of African American women having high blood pre...
A new study by NHLBI shows that ultrasonography can predict the risk of heart attack and stroke in older adults, even before traditional risk factors appear. The test measures artery wall thickness, providing valuable information for early treatment and prevention.
University of Michigan astronomers have detected the cool infrared signature of dust grains and silicates within superheated gas in the center of ancient elliptical galaxies. The discovery could represent the first direct observation of how mass lost by aging stars evolves in a hot, exotic environment.
A UK allied health professor has received a patent to test the effectiveness of combining lithium salts with existing anti-viral drug agents for AIDS patients. The proposed treatment aims to reduce toxic side effects and enhance the immune system, potentially reducing the amount of virus in the body.
Physicists Daniel Kabat and Gilad Lifschytz propose tachyons as the solution to explain how black holes absorb particles without violating M-theory. Tachyons, with imaginary mass, could provide a mechanism for energy absorption, making it possible for black holes to devour matter.
The Cellular Automata Machine (CAM) brain will be built under contract by Genobyte, a company in Boulder, Colorado. It will contain nearly 40 million artificial neurons, compared to the few hundred neurons used in most other specialists in artificial intelligence.
A team of astronomers has developed a 3-D globe-like image of the Helix nebula, allowing them to inspect it from all sides. The image reveals evidence that the nebula behaves like a double-headed garden sprinkler, with each side ejecting gas at similar structures.
The CloudSat spacecraft will produce detailed three-dimensional images of vertical cloud structures, missing from current weather forecasting models. Colorado State technology also contributes to a second NASA mission studying aerosols and thin clouds, enhancing climate change understanding.
The Digital Michelangelo Project aims to create highly realistic, three-dimensional images of Michelangelo's statues, allowing for interactive viewing from any perspective. The project will also enable the restoration of damaged areas through virtual reconstruction and the creation of accurate physical replicas.
Researchers at Vanderbilt Cancer Center found that overproduction of TGF-beta contributes to tamoxifen resistance. They also discovered the importance of immune system's natural killer activity for tamoxifen's effectiveness. This discovery may lead to strategies to prolong tamoxifen response or even reverse resistance.
Researchers at Sandia National Laboratories have created a microscopic three-dimensional lattice that confines light at optical wavelengths, potentially revolutionizing the fiber-optics communications industry. The technique appears to be the cheapest and most efficient way to bend light entering or emerging from optical cables.
