The findings support the adoption of this alternative model, which combines core dimensions of personality disorder with various m...
A new study found that insomnia symptoms in middle-aged and older adults are associated with greater future use of costly health services, including hospitalization. Insomnia is common among this population, affecting over 40% of respondents, and may be a preventable indicator of poor health outcomes.
A new study found that high levels of OR noise can have a disruptive effect on a surgeon's auditory processing abilities and cause a decrease in speech comprehension. The researchers tested 15 surgeons with varying years of experience under different listening conditions, including quiet, filtered noise, background noise, and music.
A University of Michigan study found that despite strong recommendations to use decision aids, there is a lack of evidence on whether they work effectively. The researchers reviewed 73 decision aids for breast, cervical, colon, and prostate cancers but only half were evaluated for subsequent screening behavior.
Researchers at the University of Illinois Chicago have developed a method to introduce exactly four copper ions into each quantum dot, enabling fine-tuning of optical properties and production of vibrant colors. The study opens up possibilities for producing spectacular dyes with consistent results.
Researchers have successfully given graphene magnetic properties, opening up new possibilities for the development of graphene-based spintronics. This breakthrough has the potential to transform the electronics industry by adding a new dimension to traditional electronics.
Research using GBIF data found nearly two-thirds of plants and half of animals could lose more than half their climate range by 2080. Swift action to limit emissions can reduce losses by 60% and buy additional time for species adaptation.
John Heraty will study the eucharitid wasp genus Orasema, a specialized group of ant parasitoids. More than 200 species are expected to be described as part of the study, which aims to understand relationships and species boundaries.
Researchers found that markets significantly lower moral standards, with subjects willing to accept killing a mouse for money. In market conditions, people focus on competition and profits over moral concerns, leading to an erosion of moral values.
Researchers aim to explore patterns of human collaboration in creating large-scale knowledge repositories. They seek to create a 'human-genome map' of online behavior, enabling observation and improvement of social knowledge creation processes.
A University of Colorado Boulder study suggests that a tumor suppressor gene helps cells fend off stress and survive under starvation conditions. The research found that the Rb gene regulates the expression of multiple genes to help organisms survive longer when encountering starvation.
A team of scientists has sequenced the genome of the sacred lotus, revealing its powerful genetic system that repairs genetic defects and may hold secrets about aging. The research could lead to a better understanding of anti-aging mechanisms and potential applications for human health.
Researchers from the University of Pablo de Olavide suggest that the Elephant's Tomb in Carmona, Spain was originally a temple for worshipping the god Mithras. The structure features an equinox window that aligns with celestial bodies, reinforcing this theory.
Patient satisfaction increased significantly using a pharmacist-directed anticoagulation service, with notable improvements in information communication and care quality. The study found a 10.6% rise in overall satisfaction and a 29.5% increase in satisfaction with pharmacist responses.
A University of Arizona research team has identified unusual swellings within neurons caused by statin drugs, which may lead to cognitive declines. Removing statins results in the disappearance of these 'beads-on-a-string' effects, offering promise for personalized medication and therapy.
Tropical Cyclone Jamala and newborn Tropical Cyclone 01B are both intensifying in the Indian Ocean, with Jamala forecast to reach hurricane strength and make landfall on May 14 or 15 in northwestern Burma and eastern Bangladesh.
Researchers at Weill Cornell Medical College have developed an anti-cocaine vaccine that prevents the drug from reaching the brain and producing a high. The vaccine works by generating antibodies against cocaine, rendering it ineffective, and has shown promising results in non-human primates.
Research reveals that COPD patients with allergic disease experience worsened respiratory symptoms and increased risk of exacerbations. These findings suggest that addressing allergic disease may help improve respiratory health in COPD patients, according to a new study.
Researchers at MIT have identified strains of H3N2 circulating in birds and pigs that could potentially cause a pandemic if they jump to humans. Current flu vaccines may not offer protection against these strains.
A recent study uses DNA sequencing to identify five new species of lichen-forming fungi, highlighting the importance of recognizing cryptic diversity in various ecosystems. The research also provides a reference database for specimen identification, enabling more accurate and reliable species recognition.
A study finds that private Medicare Advantage plans have cost Medicare an extra $282.6 billion since 1985, with $34.1 billion overpaid in 2012. The plans' strategies include cherry-picking healthier beneficiaries and recruiting patients from the Veteran's Administration to increase profits.
Researchers at Sanford-Burnham Medical Research Institute discovered that three children with Congenital Disorders of Glycosylation had mutation-only in some cell types, raising questions about inheritance and genomic sequencing. The study highlights the importance of using multiple diagnostic tests to accurately diagnose rare diseases.
The sacred lotus genome sequencing reveals its close resemblance to the ancestor of all eudicots, a group including apple, cabbage, and soybean. The study found that duplicated genes related to wax formation and survival in mineral-starved habitats were retained, making lotus an ideal reference plant for studying other eudicots.
NASA's Aqua satellite provided satellite images of Siberian wildfires, indicating a high likelihood due to dry conditions. The MODIS instrument detected hotspots in the region, which were then mapped over satellite images for clickable analysis.
Researchers used induced pluripotent stem cells to create a disease-in-a-dish model of ataxia telangiectasia, a rare genetic disorder causing neurodegeneration and immune system failure. The study identified potential new therapeutic drugs that can increase ATM protein activity and improve DNA repair.
A new study reveals distinct characteristics between inducible and natural IL17-producing T cells, with different signals required for cytokine production. The findings suggest a specific role of Akt protein complex in regulating cytokine production by these cell types.
