Researchers from around the world are measuring fine particulate matter (PM2.5) in Atlanta's air to understand its health effects and sources. The study aims to develop better instruments for measuring PM2.5 and its composition, with potential implications for controlling ozone and PM-related pollution.
The American Chemical Society's national meeting will feature discussions on topics such as environmental health risks, antibiotic resistance, and the origin of elements in the solar system. More than 5,600 papers are scheduled for presentation to an expected 12,000 scientists.
Researchers at the University of Washington developed a scale to measure air travel stress, finding that men and women experience it differently. The study suggests that anxiety and anger can trigger stress, but also highlights the importance of coping mechanisms such as relaxation skills and adaptive behavior.
Researchers find limited flow of male genes between subpopulations in India due to historically prevalent marriage system. However, they observe certain trends of haplotype sharing between upper and lower castes, suggesting rare conduits for male genes across social ranks.
Researchers have found that tiny air pollutant particles can penetrate deeper into the lungs of healthy adults, potentially threatening their health. The study suggests that these particles can move up to two times faster through the airways than previously assumed, with implications for public health and environmental regulations.
Researchers successfully eliminated an invasive South African worm that was causing deformed shells and stunted growth in California's abalone. By removing susceptible snails and using the 'epidemic threshold of transmission theory,' they were able to break the parasite's cycle, offering a new glimmer of hope for conservation efforts.
Researchers at the University of Washington have developed a new propulsion system called M2P2 that could potentially increase spacecraft speeds by up to 10 times, surpassing Voyager I's distance from Earth. The system uses a plasma chamber and electromagnetic field to harness the solar wind for propulsion.
Researchers have constructed the first complete physical map of an M. grisea chromosome, providing a crucial step towards understanding and combating the devastating effects of the rice blast fungus on global food supplies.
Researchers at Purdue University have developed a mathematical method that may speed the emergence of hard machining, which could make ultrahard metal parts like bearings and jet engine components more reliable and long-lasting. The new method promises to reduce waste, eliminate polluting oils, and minimize thermal damage.
