A recent study found that women have less tolerance for self-handicapping by men or women, making more negative evaluations of the behavior. Women are also less willing to excuse self-handicapping even when alternative explanations are viable, suspecting laziness and lack of motivation.
Researchers identified a complete iron-acquisition pathway in Staph. aureus, which also applies to Anthrax and Listeria. This discovery could lead to the development of new drugs to disrupt the pathway and prevent infection.
A new trial found that routine electronic fetal monitoring, known as admission cardiotocography, has no impact on infant death or moderate to severe illness rates. The practice may also increase the risk of unnecessary interventions during childbirth.
Research by the USDA Forest Service Southern Research Station sheds light on red-cockaded woodpecker conservation, revealing a preference for older pine trees with resin-rich bark. The study also shows that converting loblolly pine stands to longleaf pines can increase available food for endangered woodpeckers.
A new tool called APRA allows for detailed analysis of mRNA molecules in intact cells, revealing key interactions with the Fragile X Mental Retardation Protein (FMRP). The study provides a potential approach to develop new treatments for Fragile X syndrome, a genetic disorder that affects mental development.
Eating high-quality protein helps maintain muscle mass during weight loss efforts, burning more calories. A study found that a moderately high-protein diet resulted in greater weight loss and reduced body fat compared to a low-carbohydrate diet.
Researchers report improved left-ventricular and overall heart function in a 72-year-old man after receiving undifferentiated stem cells. The grafted scar showed the presence of well-developed skeletal myotubes with preserved contractile structure, indicating long-term viability and functional potential.
Researchers estimate that 90% of the population is gaining up to 50 extra calories a day, which can be addressed by taking an extra mile of walking each day. Closing the energy gap will also require a fundamental change in how people think about physical fitness.
Duke University researchers used a new statistical method called ordered subset analysis to identify a strong link between the GABRB3 gene and autism. By grouping patients with similar traits together statistically, they discovered a genetic risk factor that was missed by looking at the larger group.
A study found that male victims of childhood sexual abuse were more likely to become perpetrators if they experienced material neglect or lack of supervision during childhood. The risk was also increased if they witnessed violent behavior within their families.
Researchers at the University of Illinois Chicago have successfully synthesized amphidinolide T1, a highly potent compound with potential as an antitumor agent. The breakthrough, achieved through retrosynthetic analysis and sophisticated technologies, could lead to more effective cancer treatments.
A study by Duke University Medical Center researchers found that older patients undergoing coronary artery bypass surgery are more likely to suffer cognitive decline due to lowered immunity to gram-negative bacteria. Cognitive decline was particularly pronounced in patients over 60, suggesting that boosting immunity may improve outcomes.
Researchers have developed DNA scaffolding for arrays of nanoparticles, enabling the processing of large amounts of information. The technology could lead to real-time image processing and improved noise filtering, potentially even rivaling human eye speed.
Two studies found that invasive species have significantly fewer parasites than their native competitors, allowing them to outcompete and devastatingly impact native ecosystems. This advantage is due to the poor match between parasite hosts in new environments.
Researchers have created a zebrafish model that can help pinpoint genes accelerating or delaying the spread of T cell acute lymphoblastic leukemia. The model will enable testing of novel drugs against the disease, potentially leading to new treatments for cancer patients at risk.
A broad-based research program is needed to understand obesity, which cannot be easily explained by personal failing. Genes and environment interact to determine body weight, with genetic factors accounting for individual differences in weight among present time.
Satellite images from NASA's MOPITT project show high levels of carbon monoxide in regions prone to pollution, such as Southeast Asia and Australia. These images provide a new tool for monitoring air quality and tracking the spread of pollutants over long distances.
A man with kidney disease experienced severe abdominal pain after using a whirlpool in a Jacuzzi, highlighting potential health risks. The case study suggests that whirlpooling may cause mechanical injury to the kidneys, particularly under conditions like hypertension or anticoagulation.
A recent study conducted at Wake Forest University Baptist Medical Center found that weekly injections of the hormone 17-alpha-hydroxprogesterone caproate reduced pre-term birth risk by 34% in high-risk women. The treatment was also shown to be effective in African American and non-African American women.
Researchers from the University of Maryland Biotechnology Institute and Duke University discovered the genetic defect in humans and mice linked to LQT4, which affects an important adaptor protein called ankyrin-B. The defect leads to inadequate calcium regulation, causing chaotic heartbeats and potentially life-threatening arrhythmias.
Researchers discovered two enzymes necessary for mice to process three basic tastes, challenging the long-held view that distinct machinery is needed. The study also found that restoring one enzyme can selectively restore specific taste modalities.
Stanford is conducting an online self-management program for individuals with heart disease, lung disease, and type-II diabetes. The program aims to improve health outcomes by teaching participants how to manage their conditions effectively, including managing medications, exercise, and stress.
Phytoplankton communities fix carbon half as fast at pH 9, while dinoflagellates correlate strongly with high pH levels. Increased nutrient loading increases pH variability, affecting coastal ecosystems.
A new study found that providing integrated medical and health care services can reverse disparities in health outcomes between African Americans and whites. The research, published in the Journal of the American Geriatric Society, compared health status and survival rates of elderly African American and white participants enrolled in ...
Cecropin A alters bacterial gene regulation, challenging conventional thinking on its mechanism of action. The insect antibiotic's ability to evade resistance raises hope for new therapeutic agents.
A new study found that genetically modified crops in India produced yields up to 80% greater than non-Bt counterparts, while also reducing pesticide use. This breakthrough has implications for small-scale farmers in developing nations who struggle with crop losses due to pests.
Scientists found that increasing nitrogen fertilizer levels in corn hybrids boosts Bt toxin production, potentially affecting pest management. The study suggests that early-season nitrogen applications may impact the effectiveness of Bt hybrids in reducing insect damage.
A new study suggests that middle-aged mice burn fewer calories during exercise, contributing to weight gain. The researchers identified the serotonin 5-HT(2c) receptor as a potential target for therapy.
