Researchers discovered that people who experience boredom often have more anxiety and depression. To cope, individuals can shift towards left brain activity, engaging themselves in activities like reading or planning meals.
Scientists have identified a marine bacterium that can break down the polysaccharide ulvan from sea lettuce into fermentable monosaccharides. This discovery opens up new possibilities for biotechnological exploitation of ulvan, particularly in the agrifood and cosmetics industries.
A new Portland State University study demonstrates how planting more vegetation, using reflective materials on hard surfaces, and installing green roofs can help cool urban heat islands. The research found that these solutions can make a significant difference in reducing temperatures, even when applied in combination.
A comprehensive study of MS patients found that gadolinium deposition occurs early in the disease, but does not have a clinical impact. However, male patients showed more deposition than female patients, which may be related to dosage based on weight.
A new Y-shaped synthetic consortium achieves 21 g/L butanol yield, exceeding theoretical value by 85%. The consortium's adaptability and stability enable efficient simultaneous utilization of mixed sugar ratios and aeration conditions.
A recent study published in Journal of Climate confirms that the Tibetan Plateau plays a key role in enhancing East Asian summer monsoon circulation under global warming. The study found that enhanced latent heating over the plateau stimulates cyclone anomalies, leading to stronger southerly winds in East Asia.
Scientists analyzed oxygen isotopes in stalactites and stalagmites from 39 caves worldwide to understand past groundwater recharge. The study found that cave drip water oxygen composition varies between cool and warm climates, providing insights into climate variability and water resources.
Researchers at UMass Lowell have discovered that eggshell particles can increase bone cells' ability to grow and harden, potentially resulting in faster healing. The technique uses crushed eggshells in a hydrogel mixture to support bone growth, offering a sustainable alternative to traditional methods.
Researchers discovered that the Venus flytrap's tactile sensors respond to minute pressure stimuli, converting them into electrical signals that cause the trap to close. The plant has evolved smaller traps to detect the smaller forces generated by lightweight mosquitoes.
A USC study tracked prescription opioid and heroin use in teens over time, finding that those who used painkillers to get high were more likely to start using heroin by high school graduation. The study suggests a link between nonmedical opioid use and later heroin use among youth.
A new study reveals that age-related and noise-induced hearing losses affect the brain's sound processing differently. Researchers found that mild noise-induced hearing loss causes similar processing impairment as moderate to severe age-related hearing loss.
Researchers from Columbia University and Harvard are collaborating on a $1 million project to advance ultracold chemistry, enabling the study of previously inaccessible molecular species and reactions. The team aims to create a range of molecules using metal attachment and laser cooling techniques.
Researchers at Tel Aviv University have made a breakthrough discovery in genetic sex selection, allowing for the production of only female offspring in mammals. The study uses a CRISPR-protein approach to guide gene editing, eliminating male embryos while leaving females unaffected.
A new study found that nearly two-thirds of pneumonia patients in Michigan hospitals received excessive antibiotic prescriptions, with most written during the discharge process. This over-treatment can lead to physical side effects and does not improve patient outcomes.
A new international consensus document provides guidelines for the conduct of magnetic resonance imaging studies after a myocardial infarction. The main outcome measure recommended is absolute infarct size, with scanning timing between 3 and 7 days post-infarction.
Researchers developed a novel method to identify patients at high risk of HIV infection, which can benefit from preexposure prophylaxis (PrEP) strategies. The algorithm analyzed electronic health records and successfully distinguished between patients who did or did not acquire HIV, with high precision.
A study by the University of Saskatchewan found that medicinal cannabis oil containing CBD and THC can reduce or end seizures in children with severe, drug-resistant epilepsy.
