A new radar technique is being tested to track water vapor in the lower atmosphere, helping forecasters predict storm locations and timing. The REFRACTT project uses multiple Doppler weather radars to measure changes in radar signals caused by refraction, revealing the presence or absence of atmospheric moisture.
Researchers identified an accurate method to detect coronary artery disease risk in obese individuals using stress myocardial perfusion imaging. The test can help physicians plan management strategies for patients with 'silent' disease, reducing the risk of angina, heart attack, and death.
The latest NETT results confirm that selected severe emphysema patients with upper-lobe emphysema and poor exercise capacity before surgery can benefit from surgery with improved survival rates. Long-term follow-up also shows symptom relief in some patients, but no improvement in overall survival.
A recent study published in Cell reveals that mice have two proteins working together to protect chromosome ends, suggesting rapid evolution. The findings identify the distinct functions of POT1a and POT1b proteins, which could impact human telomere biology.
Research at Yale School of Medicine found significant psychological distress among Iranians exposed to high-intensity warfare and chemical attacks. Fifty-nine percent of Sardasht residents experienced PTSD in their lifetime, with severe depressive symptoms also prevalent.
Researchers found an association between specific genetic variations and a 50-100% increased stroke risk in younger women, with particular emphasis on the PDE4D gene. The study suggests a potential genetic test to identify high-risk women who may benefit from more intensive screening and counseling.
A study found that U.S. Army soldiers deployed to the Iraq war experienced mild neuropsychological compromise, including poorer memory and sustained attention performance. The researchers suggest that these effects may persist into daily life and negatively impact occupational and psychosocial functioning.
Researchers at St. Jude Children's Research Hospital developed a mouse model that explains why gene therapy treatment caused leukemia in some severe immune deficiency patients with XSCID. The study found that the disease itself makes mice susceptible to cancer caused by gene therapy, offering hope for safe treatment.
A new study published in the Journal of Clinical Investigation found that marijuana use at conception and early pregnancy can prevent embryos from safely passing to the uterus, leading to early pregnancy failure. The study also showed that THC, a psychoactive component of marijuana, can swamp normal signaling systems, causing implantat...
A new study by UMass Lowell researchers suggests that consuming antioxidant-rich apple juice may increase the production of acetylcholine in the brain, leading to improved memory. The study found that mice fed with an apple juice-supplemented diet performed better on traditional Y maze tests.
Researchers have found that continents are significantly weaker than previously suspected, with a narrow weak zone taking up most of the deformation. This discovery explains the origin of flat-lying zones of weakness known as detachment faults, which were not previously understood.
Researchers have adapted a psychiatric test for monitoring mental abnormalities in mice, revealing a key skill impaired in humans with autism and similar illnesses. The study found that mice can learn to switch attention between tasks, shedding light on the cognitive deficits underlying human mental dysfunction.
A Hopkins study shows that combining curcumin and quercetin greatly reduces the size and number of colorectal polyps in patients with familial adenomatous polyposis. The average number of polyps dropped 60.4 percent, and the average size dropped by 50.9 percent.
Conservation assessments of endangered Caribbean sea turtles are overly optimistic due to a lack of focus on declining turtle populations on historically important nesting beaches. The study highlights the critical importance of re-establishing lost nesting sites to prevent permanent population decline.
Researchers found great apes outperforming monkeys and lemurs in problem-solving tests across multiple paradigms. This suggests a broad, domain-general type of intelligence that allows them to succeed in various situations, contradicting the theory of specialized skills.
A new study in mice reveals that marijuana use at conception and early pregnancy can cause embryos to fail to reach the uterus, resulting in early pregnancy failure. The study found that THC, a major psychoactive component of marijuana, disrupts anandamide signaling, leading to impaired fertility and ectopic pregnancies.
Scientists at St. Jude Children's Research Hospital have discovered that a key event during apoptosis occurs as a single, rapid event, rather than a step-by-step process. This finding sheds new light on how cells 'commit suicide' and highlights the importance of mitochondrial outer membrane permeabilization in regulating apoptosis.
Sixty-two percent of Hispanic adults were uninsured, with three-quarters having no health insurance due to low income. Uninsured rates for African Americans are also high, with one-third experiencing gaps in coverage during the year. These disparities affect access to care and confidence in managing health problems.
A placebo study found that brain activity during a 'placebo lead-in' phase prior to antidepressant treatment can predict clinical outcomes. The study, published in the American Journal of Psychiatry, used EEG measurements to analyze changes in brain activity and its impact on depression scores.
A Johns Hopkins study found that domestic violence during pregnancy doubles the risk of death for children in the earliest stages of life. Researchers estimate nearly 1 in 5 perinatal and neonatal deaths could be prevented with domestic violence elimination.
A large-scale study found that NYC firefighters' lung function declined by 12 years of age due to WTC dust exposure, with early arrival time-based periods showing more frequent respiratory symptoms. Researchers emphasize the importance of medical surveillance for high-risk jobs and call for better protective equipment.
Research papers explore the effects of glacier shrinkage on alpine uplift, challenge previous theories on the mantle transition zone, and use stratospheric oxygen/nitrogen ratios to constrain carbon uptake budgets by the biosphere and ocean. Mineral dust aerosol emission is also enhanced by electric forces.
A study found that TB patients underweight at diagnosis who gain less than 5% weight during the first two months of treatment have a significantly increased risk of disease relapse. This association holds even among those with abnormal chest x-rays and positive sputum cultures after 2 months of anti-tuberculosis treatment.
A phase III study found that adding topotecan to standard chemotherapy for ovarian cancer does not increase overall survival or reduce cancer recurrence. The treatment instead leads to more blood-related toxicities and infections.
Researchers found that taller, faster-growing children are more vulnerable to the effects of an obesogenic environment. The study, which surveyed 50,000 three-year-olds, showed a strong relationship between child growth and obesity.
A new study published in Obesity journal found that societal pressure on weight can discourage adults from adopting exercise and healthy lifestyle habits. The research highlights the importance of shifting focus away from specific target weights and promoting physical activity and healthy eating habits instead.
Scientists have discovered evidence of man's environmental impact at an underwater volcano, revealing lead pollution originating from Australia that traveled thousands of miles to the Mediterranean. The study highlights the growing power of using high-precision isotopic measurements as a tracing tool.
A fleet of underwater robots will work together to make detailed observations of the ocean without human aid. The project has potential implications for ocean forecasting, marine conservation, and exploration of other environments.
Researchers found that a healthier balance of omega-3 and omega-6 fatty acids can reduce prostate cancer tumor growth rates and PSA levels by 22% and 77%, respectively. The study suggests using EPA and DHA supplements to lower inflammatory response in prostate cancer development.
The Osteoarthritis Initiative (OAI) has released its first set of data, featuring images and clinical outcome information for nearly 5,000 participants at risk of knee osteoarthritis. The data will facilitate the discovery of biomarkers for development and progression of OA.
