A University of Michigan-led research team is launching a two-year study to examine whether prisoners of war experience 'post-traumatic growth' after their traumatic experiences. The study aims to determine if POWs develop positive changes in self-perception, interpersonal relationships, and philosophy of life compared to control groups.
A new study found that 16% of insured individuals who use inhaled beta-agonists for short-term asthma relief overuse their medication, while 63% who use inhaled corticosteroids for long-term relief underuse them. The study also revealed a gender bias, with women more likely to underuse and men more likely to overuse.
A new study found that a sharp decrease in solar wind density caused Earth's magnetosphere to balloon to more than 100 times its normal volume, reaching nearly to the moon. The event, dubbed "The Day the Solar Wind Ran Out of Gas," was rare and only seen a few times since satellites began measuring solar wind 35 years ago.
A study found that antidepressant use increased with age, particularly among women, suggesting improvements in detection and treatment of mental health disorders. Women were 70% more likely to use antidepressants than men, regardless of age.
NASA scientists presented new findings on ozonesonde data, glaciers, Mars impact features, Landsat-7 mission performance, tropical landscapes, and more. The results include insights into ozone layer changes, ice stream movements, and buried impact basins on Mars.
Researchers found that genetically modified Bt corn releases the insecticidal toxin into the soil through its roots, posing a risk to beneficial insects. The toxin was shown to retain its insecticidal activity for 234 days and can affect soil communities in unknown ways.
A study by UMass researcher Robert S. Feldman found that convincing lying is associated with good social skills, particularly among older adolescents and those with high social competence. This suggests that being a better liar can make someone more popular, but only when controlling nonverbal behavior.
Scientists have developed a new technique using ice-penetrating radar to study long-ago changes in West Antarctic ice streams. This allows them to look at changes much farther back in time, indicating possible fluctuations in the stability of the massive West Antarctic Ice Sheet.
The Landsat 7 spacecraft has acquired over 50,000 scenes of the Earth's surface, providing detailed images of natural disasters, unique weather patterns, and glacial changes. The satellite's data will support global change research and inform decision-making about environmental issues.
A new study suggests that a diet without vitamins A and E may help cancer patients by reducing the size of brain tumors and inducing oxidant stress in cancer cells. This could lead to improved outcomes for those undergoing chemotherapy or radiation therapy, as antioxidants can prevent cancer cells from self-destructing.
Researchers at Purdue University are developing a new type of environmentally friendly fuel cell that generates about 20 times more electricity per pound than car batteries. The cell produces electricity through chemical reactions between hydrogen peroxide and aluminum.
African nations can become more prosperous and politically stable by pooling their energy resources through regional electric power grids, according to Purdue University industrial engineers. Cheaper and more widely available electricity would spur industrial and economic growth in regions of southern and western Africa.
Researchers use Canadian Radarsat satellite data to uncover tributaries feeding giant ice streams, changing understanding of Antarctic ice sheet dynamics. High-resolution radar maps reveal complex patterns and fast-flowing glaciers, shedding light on the continent's past and potential sea level rise
Researchers have identified a gene called Mre11 as a critical component of the regulatory network that cells activate in response to DNA damage. This discovery explains how mutations in Mre11 can cause ataxia-telangiectasia, a genetic disorder characterized by progressive nerve and muscle loss and increased susceptibility to cancer.
A study of 700 street youth found that geographic mobility and high-risk behaviors contributed to the spread of HIV among young people. The majority of those infected were male, aged 23-25, with high levels of unprotected sex, prostitution, and intravenous drug use.
Researchers compared local and remote aerosol measurement techniques to better understand their chemistry and physics. The study used a combination of ground-based instruments and satellite lidar to analyze pollution levels and their impact on climate change.
Scientists identify key lipids essential for proper myelin sheath formation, providing new insights into myelin biology and multiple sclerosis. The discovery sheds light on the molecular mechanisms underlying nerve sheath abnormalities.
A study of over 15,000 people found that residents of the South consumed the most produce daily, while those in the Northeast had the lowest intake. African Americans and college graduates also showed higher consumption rates, highlighting the need for tailored messages to promote behavior change.
Researchers at Purdue University are developing a silicon detector, Si3, to analyze subatomic particles and test the widely accepted standard model of physics. The detector will help investigate why the universe is predominantly made of matter rather than antimatter.
