Athletes with asthma face increased risk of symptoms due to high minute ventilation and poor air quality during exercise. Individualized management plans are crucial to comply with anti-doping regulations.
The New Zealand mud snail is outcompeting native species, altering food chains and ecosystems in the Great Lakes. Research suggests the snails can survive being frozen for short periods, making control difficult.
Scientists at the University of California, Davis have developed a simple and inexpensive process to directly convert cellulose into furan-based biofuels. This method surpasses previous conversions, offering a promising solution for sustainable energy production.
A study published in the Journal of Computational Neuroscience found that brain cells processing visual information adjust their filtering properties to make sense of incoming data. The researchers discovered that odd-symmetric components induce systematic changes across the population of neurons in the V1 area of the visual cortex.
Researchers discovered insects use air bubbles to survive underwater, but find limits to depth and surface area. The study found bugs can dive as deep as 30 meters without bubble rupture.
A team of scientists discovered that mirid bugs possess a 30 times thicker coating than blowflies, which disrupts the glue's adhesive powers, allowing them to escape. The unique greasy layer prevents the glue from forming discrete blobs, instead running like a fluid over the surface.
Researchers have shown that early treatment for Hepatitis C virus (HCV) within the first months following an infection develops a rapid poly-functional immune response against HCV. This finding suggests that early treatment can restore immune response and help eliminate the virus rapidly, contributing to the development of new treatments.
A new study funded by the Economic and Social Research Council argues that hope is essential for effective HIV prevention strategies. People with hope are more likely to adopt realistic plans and engage in protective behaviors.
Researchers at UCLA and Intrinsic LifeSciences have developed the first method to directly measure hepcidin, a hormone that regulates iron absorption. The new blood test will help clinicians diagnose conditions like anemia of chronic disease and hemochromatosis more efficiently.
Researchers at Wake Forest University Baptist Medical Center are launching a study to investigate the impact of mistrust in medical care on Latino HIV patients' mortality rates. The study aims to understand cultural and social factors contributing to this disparity.
The MIBBI initiative brings together grassroots standardisation groups to create a unified framework for high-throughput biology. By sharing minimal information standards, researchers can increase data reproducibility and analysis power.
A phase I/II study found that intrabone administration of unrelated cord-blood cells increased the number of patients who could receive hematopoietic stem-cell transplantation. The technique reduced the incidence of graft-versus-host disease, a common complication of allogeneic transplants.
A study found a link between genetic variation in the CHRNA5 gene, initial smoking experiences, and current smoking habits. Smokers were eight times more likely to report pleasurable first cigarettes, suggesting that genetics may play a role in nicotine addiction.
A study published in the American Journal of Clinical Nutrition found that consuming oily fish at least once a week may reduce the risk of age-related macular degeneration (AMD) by 50%. Researchers associated high levels of omega-3 fatty acids with lower AMD risk, particularly those above 300mg per day.
A paper by F. Stuart Chapin III and colleagues presents policy strategies for sustainable management of Alaskan boreal forests in response to climate change, integrating ecological and social sciences. The award recognizes the research's contribution to sustainability science.
Researchers found that nearly 60% of tree species in Guam rely on native birds for seed dispersal, which could have significant impacts on forest ecosystems. The study suggests that the loss of native bird species due to invasive brown tree snakes may lead to reduced tree populations and altered ecosystem dynamics.
Researchers found that dopamine strengthens the 'go' circuit and weakens the 'stop' circuit in the brain, leading to compulsive behavior and addictive tendencies. The study also shows how Parkinson's patients' reduced dopamine levels lead to frozen motor skills.
Research finds that PSA screening can lead to delayed diagnosis and more aggressive cancer outcomes for obese men. The study suggests that alternative screening methods or lower threshold for worrisome PSA levels may be necessary for this population.
A new study found that referees tend to award more points to tae kwon do competitors dressed in red than those dressed in blue. The researchers discovered a split-second bias toward red-clad athletes when competitors are evenly matched in skill.
Research suggests that increased testosterone in male mice increases their ability to transmit diseases, driving transmission through close social contact. The study found that treated mice made significantly more contacts with both males and females than untreated mice, leading to a higher risk of disease spread.
A recent study by Harvard researchers found that coronary CTA is more cost-effective than current tests for diagnosing low-risk women with acute chest pain. The study suggests that CT angiography can reduce total healthcare costs by $380 and emergency department costs by $410 compared to standard care.
