A new study finds that alcohol-related injuries among underage youth and young adults are shaped by the density and types of alcohol outlets in neighborhoods. Off-premise outlets, such as take-out establishments and bars, are linked to higher injury rates, including accidents, assaults, and traffic crashes.
A new supplement provides essential reference and set of tools for evidence-informed health policymaking. The series addresses four broad areas and contains 17 support tools from renowned experts.

The study collected data from 3,005 older adults across the US, finding that men tend to have more positive attitudes towards sex and are more likely to be sexually active. The research also highlights the importance of promoting positive social relationships in older age.
Researchers found that physicians' bedside exams did a better job than CT scans in predicting which patients would need to return to the operating room to treat complications such as bleeding. The low-cost, simple exam appears to be superior to routine CT scans in determining return to the operating room.
Researchers have developed a new technology called 'T-rays' that can penetrate through opaque dry materials without causing harm. This breakthrough could lead to new security measures, such as detecting weapons or drugs concealed on a human body, as well as medical applications, including material studies and biology.
A new study suggests that medical liability concerns may be driving doctors to overprescribe antibiotics in healthcare settings. The research found a strong correlation between antibiotic use and attorney density in European countries, but no such link with physician density.
A new study finds that alcoholics can improve their postural sway with prolonged sobriety, but the improvement may not fully erase the problem of instability. Researchers found that stabilizing factors such as turning on a light or walking with feet apart can help improve standing stability in sober alcoholics.
A team of researchers has developed a new method to produce bioglass nanofibers, which can be used to regenerate bone tissue. The laser spinning technique allows for the production of flexible and continuous nanofibers with a nanometric structure, enabling the proliferation and spread of bone cells.
According to a new study, autism disorders have become more common among American children, with a prevalence rate approaching 1 percent among 8-year-olds. The study found a 57 percent increase in spectrum-disorder cases compared to four years earlier.
A recent study found that genetic factors contribute to both alcohol and marijuana use, with shared genetic influences contributing to dependence symptoms. The research used a large annual survey of high-school students and found strong evidence for a genetic component to marijuana use and dependence.
A team of researchers has made a breakthrough discovery about the defective protein that causes cystic fibrosis, understanding its special relationship with pH levels inside cells. By regulating acid-base balance, the protein controls salt transport and cell survival, offering hope for developing new therapies to restore function.
A study published in Alcoholism: Clinical & Experimental Research found that bourbon causes worse hangovers, but impairment in task performance is similar to vodka. Researchers recruited heavy drinkers and tested their sleep patterns, self-report symptoms, and neurocognitive measures after consuming bourbon or vodka.
Researchers at Université de Montréal discovered that recalling celebrity faces decreases with age, but accessing biographical knowledge via their name remains unaffected. This semantic memory test could become a crucial tool to identify individuals at risk of developing Alzheimer's disease.
The guide highlights key infection risks faced by transplant recipients, including pet ownership, food safety, and travel plans. It provides advice on how to minimize exposure to potential sources of infection and reduce the risk of respiratory, waterborne, and food-borne illnesses.
A new newsletter highlights health care utilization patterns among older Asian minorities and perceived job discrimination among older workers. The Gerontological Society of America emphasizes the need for research to resolve barriers in seeking health care for minority elders.
Scientists are studying the physical processes of ice formation in insects to understand why some survive freezing while others don't. The research found that insects that freeze at consistently higher temperatures have adaptations that allow them to control ice formation, implying cellular or biochemical level adaptations.
Research links BRCA1 gene mutations to lower ovarian response rates in women undergoing fertility preservation treatments for breast cancer. Women carrying the mutated gene are more likely to experience infertility due to decreased egg production.
Researchers explore the development and morphology of insect-mimicking spots on the flower petals of a South African beetle daisy. The study found that these spots are composed of three types of epidermal cells, each spanning four fused petal lobes, and are influenced by UV reflectivity and anthocyanin pigment.
Researchers at Washington University have developed a sensor that can detect and measure single nanoparticles using an ultra-high-Q microresonator. The sensor exploits the phenomenon of whispering-gallery mode resonance, where the light wave interacts with the particle on the ring's surface.
A study from Université de Montréal and Douglas Mental Health University Institute found that 10-15% of women experience maladaptive eating behaviors, which can lead to binge eating, bulimia, and excessive exercise. The study also revealed a link between problematic eating habits and self-rated health.
The W.M. Keck Foundation has completed its 11-year Distinguished Young Scholars Program, awarding nearly $55 million to 54 young scientists who have gone on to publish pioneering work and assume leadership positions in their fields. The program provided flexible funding support to young investigators.
Lowell Observatory Director Eileen Friel has been selected as an AAAS Fellow for her contributions to the astronomical community. She is recognized for her diligence in mentoring young scientists through the Research Experiences for Undergraduates program.
A Commonwealth Fund survey found nearly half of young adults (19-29) are uninsured at some time, with key transition times like graduation posing significant risk. The majority support reforms that make health insurance more affordable and protective.
A study published in the December 2009 issue of HeartRhythm found that only half of eligible heart failure patients received implantable cardioverter-defibrillators (ICDs) to prevent sudden cardiac death. The study also revealed wide variations in ICD use, with certain patient groups more likely to receive the devices.
Researchers at Texas A&M University have discovered a potential new approach to slowing the spread of cancer by modifying the structure of malignant cells. By understanding how signals alter the cytoskeleton, they may uncover new targets for treatment.
Researchers at Binghamton University identified three key regulators required for biofilm formation, which could lead to new treatments for chronic infections. Biofilms are implicated in over 80% of chronic inflammatory and infectious diseases, and conventional antimicrobial treatments are often ineffective.
Research suggests that commercially marketed raisin bran cereal causes significantly higher levels of acid in dental plaque than plain bran flakes or unsweetened raisins. Conversely, unsweetened raisins do not increase plaque acidity when added to bran flakes.
