A new study found that nursing home residents have a fivefold increased risk of falling within two days of a new prescription for or an increased dose of non-SSRI antidepressants. The study suggests that staff should closely monitor these residents following a prescription change to prevent potential falls.
Scientists report that the world's forests store approximately 2.4 gigatons of carbon per year, with boreal forests accounting for nearly 22% of total stored carbon. A warming climate may reduce the capacity of forests to sequester carbon, highlighting the importance of understanding their role in the global carbon cycle.

The law allowed hospitals to hire licensed practical nurses to meet staffing requirements, helping to alleviate a severe nurse shortage.
Research from the University of Michigan Medical School found that children with public health insurance are 22% less likely to have a medical home, a model for pediatric primary care. Despite this, over 90% of publicly-insured children reported having a usual source of medical care.
Physicist Olivier Pfister and his team create 60 measurable Qmodes, a multilevel variant of entangled qubits, in a major step towards building a quantum computer. This achievement has significant implications for quantum computing, potentially revolutionizing fields such as data encryption and complex system simulations.
Researchers found that short telomeres increase emphysema risk after cigarette smoke exposure, suggesting a biological clock mechanism. Telomere length may be an inherited factor contributing to emphysema development.
Researchers at Penn Vet found a cancer drug that shrinks dog tumors and may lead to human treatment. The study discovered the same aberrant activation of a critical pathway in dogs with lymphoma as humans.
A University of Arizona-led team found that rising sea levels during the Last Interglacial Period were primarily driven by melting ice sheets, rather than thermal expansion. The study suggests that even small amounts of warming may have committed to more ice sheet melting, and sea levels will continue to rise for a long time.
A new study confirms that a low level of response (LR) to alcohol increases risk for heavy drinking and problems among adolescents. LR is related to more adverse outcomes through partial mediation by peer substance use, positive expectancies, and using alcohol to cope with stress.
A USC study reveals that empathetic responses are generated by both the sensory-motor and rationalizing parts of the brain. The research found that even individuals with physical differences can understand pain in a different limb due to automatic brain processes.
A new knowledgebase, Kbase, will integrate disparate data streams on plants and microbes to facilitate question-asking about huge datasets. This will help make progress on improved ways to generate biofuels and optimize plant yields.
Scientists have identified molecular differences between disease-indicating proteins and those that exist naturally, enabling the development of reliable diagnostic tests. This breakthrough could lead to earlier diagnosis and treatment of fatal diseases, such as cancer.
Researchers at Mayo Clinic discovered a genetic mutation in VPS35 that causes Parkinson's disease, leading to protein buildup in the brain. This finding opens up new avenues for understanding and treating the complex disease.
Researchers at UWM have discovered that propranolol, a common beta blocker, can prevent the brain from retrieving memories associated with cocaine use in animal models. This finding could lead to the development of a first-ever pharmacological treatment for cocaine addiction.
A new gene, MAN1B1, has been identified as the cause of recessive intellectual disability in five families. The gene codes an enzyme involved in quality control functions in cells, leading to faulty proteins being released into the body.
A new study found that a global payment system in Massachusetts lowered medical spending by nearly 2% while improving the quality of patient care compared to traditional fee-for-service systems. The Alternative Quality Contract (AQC) model, which includes more than a third of Blue Cross Blue Shield of Massachusetts' provider network, s...
The NASA Aura satellite measures pollution 'butterfly' formed by nitrogen dioxide (NO2) emissions from agricultural fires in central Africa. High concentrations of NO2 were detected over the Democratic Republic of Congo and northern Angola, posing a threat to air quality and health.
A team of biochemists at the University of Arizona discovered that disrupting a molecular process used by mosquitoes to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding. This approach could be used as an additional strategy in the worldwide effort to...
NASA's Aqua satellite captured clear images of Typhoon Ma-on's eye, indicating a strong storm. The typhoon has strengthened to Category Four status with maximum sustained winds at 132 mph.
Wake Forest University and Fisk University have partnered to create crystals that can accurately detect nuclear threats, radioactive material, and chemical bombs. The $900,000 grant will support research in radiation detection, leading to improved detector devices for screening cargo and passengers.
A new study by NOAA finds that strong El Niño years can lead to nearly three times the average number of storm surge events along the East Coast, with a third-of-a-foot elevation in mean sea level. Coastal communities may need to prepare for higher sea levels and more destructive storm surges.
Researchers Richard Boone and Pat Marsteller propose enhancing the NSF's GK-12 program, which has placed 10,000 graduate students in over 6,000 schools. The revamped program aims to strengthen science education for K-12 students and improve teaching skills for graduate students.
Two studies published in Appetite found that consuming in-shell pistachios reduces calorie intake by 41% and provides visual cues to control portion size. Pistachio shells offer a simple technique to fool oneself full, supporting the 'Pistachio Principle'.
Researchers at Duke University Medical Center found that donated red blood cells lose their key feature to diminish lifesaving power with storage time. This loss can lead to complications in critically ill patients, prompting a search for ways to optimize transfusion benefits and extend stored blood's shelf life.
Researchers in Argentina used fossilized insect cocoons to describe how wasps played a crucial role in consuming rotting dinosaur eggs. The study provides insight into the murky world of insect communities that thrived at the feet of gigantic dinosaurs.
A new study found that female teens who binge drink have less brain activation and worse performance on attention and working memory tasks. Male binge drinkers showed some but less abnormality compared to non-drinkers. The findings suggest that adolescent girls may be more vulnerable to the negative effects of heavy alcohol use.
Researchers found that alpha males in Kenya's baboon groups have higher glucocoricoid levels, indicating a potential cost to high social rank. The study has implications for human behavior and societal structures.
The decline of apex consumers has triggered trophic cascades, affecting ecosystem dynamics and leading to changes in vegetation, wildfire frequency, and disease outbreaks. Restoration efforts focus on reestablishing large animals, requiring large-scale approaches to conserve functional ecosystems.
A recent study published in the American Journal of Preventive Medicine found that Massachusetts health reform led to a 7.6% increase in health insurance among residents and a 4.8% decrease in those forgoing healthcare due to cost
A new study found that acute stress can increase alcohol consumption by altering its effects, while chronic stress may prolong recovery from a stressful event. The study's results suggest that using alcohol to cope with stress may actually make a person's response to stress worse.
