Researchers at UCLA found that traumatic brain injury increases risk of Parkinson's disease, with a moderate injury causing a 15% loss of nigrostriatal dopaminergic neurons. Exposure to the pesticide paraquat doubles this risk and accelerates neuronal degeneration.
The molecular structural basis for severe head deformities and ambiguous sex organs in babies born with Antley-Bixler syndrome has been revealed, suggesting that riboflavin therapy may reverse enzyme defects. The study also found that the enzyme NADPH-cytochrome P450 reductase plays a crucial role in human syndromes.
A recent study published in Pediatric Research found that mothers with a higher pre-pregnancy body mass index (BMI) have fatter babies with more fat in their liver cells. The researchers measured the amount of fat in 105 babies' livers and bodies, finding increased liver cell fat and total fat across all BMI ranges. This study suggests...
Scientists have discovered a new binding site on the most common subtype of nicotinic acetylcholine receptors, which could lead to the development of better medicines for psychiatric disorders. The findings challenge existing scientific ideas and provide a general mechanism that applies across the receptor family.
The University of Kentucky Sanders-Brown Center on Aging is receiving over $7 million from the National Institute on Aging to continue its research and clinical initiatives focused on treating Alzheimer's disease. The funding will support ongoing programs, including telemedicine services, brain donation, and outreach efforts.
A new report from Berkeley Lab scientist shows that oil-degrading microorganisms played a significant role in both the Exxon Valdez and BP Deepwater Horizon spills. The study found that mobilizing these microorganisms rapidly can minimize the risk and impact of future oil spills.
A new collection of research articles focuses on physical activity and sport participation across the lifespan, exploring its benefits for mental, physical, emotional, and social health. The book features contributions from scholars in eight countries and four continents.
A recent study by McGill University researchers found that biodiversity is essential for maintaining multiple ecosystem services across different years, places, and environmental conditions. The study suggests that many species are needed to maintain ecosystem services, rather than just a few, and highlights the importance of conservin...
A recent study published in American Political Research found that English language ads had a greater impact on Latino voter turnout compared to Spanish language ads. The study also showed that English language materials drew in a broader voter demographic and were effective across all levels of Latino voters.
A study by UCSD researchers reveals a rapid increase in hookah use among California youth aged 18-24, with most users smoking with friends. Hookah is perceived as a safer alternative to cigarettes despite being less healthy, prompting calls for laws to ban hookah lounges.
A new study from the University of Alberta found that combining metformin with exercise does not provide additional benefits for glucose control. In fact, it may trigger a counter-regulatory response in the body, leading to increased glucagon levels and reduced glucose control after exercise.
Researchers will use genome-wide association studies to identify genetic variants associated with diseases, enabling the adjustment of patient medications and prevention of diseases. The eMERGE network has already identified genetic variants linked to dementia, cataracts, type 2 diabetes, and more.
A new study from Temple University found that medical examiners and appointed coroners are less likely to underreport suicides compared to elected coroners. This suggests that insulation from public pressure can lead to more accurate suicide reporting.
Researchers at Stanford University have developed a new method to detect sunspots forming deep inside the sun, allowing for up to two days' warning before solar storms. The method uses acoustic waves generated by turbulent plasma and gases, and has been successfully tested four times.
Soil nitrogen can remove pollutants from the atmosphere by forming hydroxyl radicals, which oxidize and wash out pollutants. The amount of nitrous acid released depends on soil acidity and water content.
A meta-analysis predicts that cities will expand by 590,000 square miles globally by 2030, threatening biologically diverse areas. Rising incomes in China drive half of urban land expansion, while population growth drives expansion in India and Africa.
A new study found that a combination of minocycline and EDTA can prevent bacterial infections in dialysis patients using catheters, improving patient outcomes. The treatment reduced the risk of infection by half compared to traditional heparin use.
Researchers have discovered a potential treatment for cancer of the immune system, targeting the Epstein Barr virus receptor EB12. The discovery was made by mapping the bio-antenna molecule and creating a blueprint of a tiny molecule that can bind to the B cell EB12 receptor, blocking its activation.
Experts warn that climate-related damage to nation's infrastructure is on the rise, with potential costs exceeding $2 trillion. The summit identifies key initiatives for next five years, including assessing vulnerable infrastructure, developing risk assessment tools, and improving stakeholder dialogue.
The University of Southampton has received £17m funding to support its world-leading nutrition and respiratory research facilities. The National Institute for Health Research has allocated £7.3m to the Respiratory Biomedical Research unit, while the Nutrition, Diet and Lifestyle Biomedical Research Centre will receive £9.6m.
People with metabolic syndrome have a 55% increased risk of developing kidney problems, especially lower kidney function. Preventing and managing metabolic syndrome through healthy diet, exercise, and weight loss may help prevent kidney disease.
U of A researchers explore hypothetical economic models that suggest oil producers should pay attention to emerging alternatives. If an alternative resource becomes more economically attractive, oil producers may have to adjust to make sure they don't hasten their own obsolescence.
Researchers at Stanford University discovered that Toxoplasma-infected male rats exhibit altered brain activity in response to cat urine, suggesting a manipulation of fear and attraction pathways. The parasite benefits from this alteration, as infected rats become less fearful and more drawn to cats.
Researchers have discovered how malaria parasites camouflage themselves from the immune system of pregnant women, allowing them to go undetected. This finding has significant implications for developing a vaccine to protect expectant mothers from maternal malaria.
Tropical Depression 8 is expected to produce heavy rainfall across Honduras, Guatemala, and Belize, with total accumulations of 3-5 inches possible. Isolated areas may see up to 8 inches, posing a risk of flash flooding and mudslides.
