Adding nitrogen to gallium indium arsenide decreases its band gap dramatically, a significant finding for advanced solar cells. The discovery explains why the material has been disappointing in solar cells so far.
A new study by Penn State researchers improves the regional climate assessment of the Mid-Atlantic Region. The research involved gathering input from over 95 stakeholders representing industry, environmental groups, government, and research organizations. Key findings highlight the importance of human health in addressing global change...
A new study by University at Buffalo exercise scientists reveals that dehydration can induce bronchospasm before exercise and exacerbate exercise-induced asthma. Researchers found that individuals with asthma are more sensitive to dehydration, leading to reduced respiratory capacity and increased difficulty during physical activity.
A standardized treatment protocol for severely malnourished children has been shown to reduce mortality rates by 47%. The new protocol includes slow rehydration, immediate feeding with locally available foods, routine micronutrient supplementation, and broad-spectrum antibiotic therapy.
Naturally occurring micro-organisms that live at the bottom of lakes and streams have been shown to convert gasoline additives, including MTBE, into harmless byproducts. The study suggests that these micro-organisms can act as a significant barrier to the entry of MTBE into surface water systems.
A University at Buffalo study found that men recovering from a heart attack who are at the highest risk of a second attack are also the least likely to participate in an exercise program. These men tend to be overweight, have high cholesterol and triglyceride levels, and smoke tobacco.
The report in Science reveals the x-ray crystal structure of MMP-2, a key target for anti-cancer drug candidates. The elucidated structure provides valuable information on the function and regulation of MMP-2, enabling the design of improved inhibitors.
New research from Washington University in St. Louis suggests that false recall in older adults with Alzheimer's is related to attention breakdowns rather than memory decline. The study found that older adults are susceptible to creating false memories, which challenges the idea of a broad general decline in all memory-related functions.
Researchers have successfully used fMRI to generate high-resolution pictures of active brain regions in monkeys under anesthesia. The technique allows for precise visualization of brain activity, challenging previous assumptions about the effects of anesthetics on brain function.
Twenty U.S high school students have been chosen to compete in the 31st International Chemistry Olympiad. They will participate in a two-week study camp at the U.S Air Force Academy before representing the US team in the global contest.
A new study by Ohio State University researchers found that people with high self-doubt focus on the difficulty of coming up with positive examples, leading to lower self-esteem. In contrast, those with low self-doubt focus on the positive experiences, resulting in improved self-regard.
The first 3D topographic images of the lunar polar regions have been revealed by Cornell University researchers, indicating potential sites for water ice deposits. The new images obtained through radar interferometry show five large craters in the south polar region that could contain significant amounts of water ice.
A landmark study assessing New York City's metropolitan area for climate change challenges has been presented by Cynthia Rosenzweig. The project pairs scientists with local governments to inform decisions on aging roads, public health, and coastal erosion.
