A new study reveals that nearly a third of zooplankton's diet comes from land-derived organic matter. The research provides insight into the complex interactions within aquatic food webs and the role of watershed inputs.
Researchers found that portable HEPA filters reduced fine particulate matter and woodsmoke concentrations, improving endothelial function and decreasing inflammation. These findings support the hypothesis that reducing particle concentration can favorably influence cardiovascular morbidity.
Research by Dr. Sébastien Sauvé and André Lajeunesse found that antidepressants accumulate in fish tissues, affecting brain activity and potentially causing long-term harm to the Saint Lawrence River's ecosystem. The study's findings highlight the need for further research into the impact of chemical pollution on aquatic organisms.
Researchers identified miR-96 as a key regulator of auditory sensory hair cell development. The study revealed that mutations in this microRNA prevent the normal progression of hair cell development, leading to deafness. This breakthrough discovery opens new avenues for developing treatments for progressive hearing loss and deafness.
Researchers found a significant decrease in tooth decay among young American Indians who switched from sweetened soda to water, with up to 63% reduction in early stage cavities. The study suggests that promoting water as a primary drink can have a substantial impact on preventing tooth decay.
Researchers at MIT have discovered a new process relating to the way drops of water spread after striking a surface, which could help engineers design more durable condensing surfaces. The effect explains why blades used in power-plant turbines tend to degrade rapidly and need frequent replacement.
A new study found that traditional dietary surveys, relying on self-reported data, are inconsistent and can be influenced by memory impairment and digestive issues. Using nutrient biomarkers through blood tests, researchers aim to improve the accuracy of nutritional assessments and develop more effective therapies for cognitive health.
A new study reveals that the Greenland Ice Sheet experienced its highest melting event in 2010, breaking records by up to 50 days. This unusual phenomenon was attributed to extreme temperatures and reduced snowfall during the summer months, which exposed bare ice earlier than usual.
A study at Massachusetts General Hospital found that CT scans significantly improved physicians' confidence in their diagnosis, changing treatment plans for almost half of patients with abdominal pain. This resulted in reduced probable hospital admissions by 20% and lower overall costs.
UB's Pop! World uses cloud computing to make evolutionary biology visually appealing, allowing college students to understand complex mathematical concepts. The tool is scalable and adaptable, making it suitable for both undergraduate and secondary school students.
Researchers at Case Western Reserve University School of Medicine will continue studying manic symptoms in children with a renewed $7.8 million NIMH grant. The study aims to develop accurate diagnoses and predictive factors for bipolar spectrum disorders in youth.
A new Northwestern Medicine study found that 80% of NFL linemen who underwent disc surgery were able to return to play many games, suggesting that average people can also resume their active lives. After proper recovery and rehabilitation, patients can safely lift weights and engage in strenuous activities without long-term risks.
Arun Chatterjee, a professor emeritus at the University of Missouri, was elected to the American Association for the Advancement of Science (AAAS) for his groundbreaking research on Erwinia carotovora, a bacterium that causes disease in various plants. His work has shed light on the regulatory role of small RNAs in controlling protein ...
Two bacterial enzymes, AAD-1 and AAD-12, have been identified as conferring robust resistance to 2,4-D in corn and soybeans. The discovery may provide a solution to the spread of herbicide-resistant weeds, allowing growers an alternative to glyphosate.
A 12-week mindfulness meditation program shows measurable changes in brain regions associated with memory, self-awareness, empathy, and stress. Increased grey-matter density was observed in areas important for learning and memory, as well as structures linked to compassion and introspection.
A University of Manchester scientist has discovered the mechanism behind skin cells' tight binding, which could lead to new treatments for debilitating skin diseases and heart problems. The study found that glue molecules bind specifically to similar molecules on neighboring cells, creating a resilient structure.
Researchers investigate how the insula integrates affective and cognitive processes, and how neural systems develop with age. They also examine the role of vision in auditory and tactile integration, and find that vision plays a crucial role in developing this integration.
Scientists have documented elevated levels of PCBs and PBDEs in carp from eastern Lake Erie, which can disrupt endocrine systems and cause health issues. The findings highlight the lasting effects of human activity on the Great Lakes' ecosystem.
A study investigated the impact of disease-resistant genetically-modified (GM) wheat lines on insect food webs. The findings show that the differences between GM and non-GM wheat strains are similar to those found between different conventional wheat strains, suggesting no ecological problems with GM wheat.
Researchers identified specific genetic mutations that predict tumor aggressiveness and treatment response in patients with neuroendocrine pancreatic cancer. The study's findings could lead to personalized cancer therapy and improved patient outcomes.
The study reveals that industrial and traditional fishing activities are putting the monk seal and Atlantic hump-backed dolphin at great danger due to over-exploitation of resources. The researchers call for stricter regulation and monitoring of fishing practices to protect these species.
Researchers found that bee-pollinated Penstemon species have distinct genetic clusters per mountain range, while bird-pollinated species show less genetic structure across ranges. Hummingbirds facilitate gene flow among distant populations, constraining local adaptations.
Researchers at Dow AgroSciences and the University of Missouri have engineered soybean plants that can tolerate an alternative herbicide called 2,4-D, which may help slow the spread of superweeds. This new approach could reduce the need for multiple herbicides and lead to cost savings for farmers and consumers.
The human body produces a human antibiotic, beta-defensin 1, in remarkable quantities despite showing little activity against microbes under standard conditions. However, research discovered that this protein unfolds strong antibiotic activity against lactic acid bacteria and yeast under low-oxygen conditions.
