Younger children and teens often have built-in opportunities to stay active through gym class, sports, and extracurricular activities. But after high school, those structured options often disappear. And many young adults ...
Medical Xpress / Suicide prevention measures can help AI better protect young users
Suicide prevention approaches are key to making sure conversational AI is safe for youth, argues a commentary in the Canadian Medical Association Journal. The adoption of AI chatbots by youth as a source of mental health ...
Medical Xpress / Transparency needed in addressing physician sexual misconduct, say researchers
A new study on physician misconduct using publicly available data on 208 physicians involved in cases of sex- or gender-based violence, harassment, or discrimination found gaps in how physicians were monitored and sanctioned. ...
Medical Xpress / Largest US study finds teen cannabis use linked to slower cognitive development
Researchers from University of California San Diego have found that teenagers who begin using cannabis show slower gains in thinking and memory skills as they grow. The study, published in Neuropsychopharmacology, analyzed ...
Phys.org / Atlantic current shows two-decade decline across four deep-ocean monitoring sites
A paper published in the journal Science Advances is adding to the growing body of research showing that the Atlantic Meridional Overturning Circulation (AMOC) is weakening. In this new study, instead of relying mainly on ...
Phys.org / These blazing blue explosions may be born when a compact dead star slams into a Wolf-Rayet star
Luminous fast blue optical transients (LFBOTs) are among the universe's brightest and fastest explosions but their origin is not completely understood. A new study takes a closer look at the galaxies they occur in, offering ...
Medical Xpress / Robust flu protection may rely on B cells that are long-lived residents in the lungs
Deep in the lungs, resident memory B cells stand guard against influenza reinfection—but whether they remain there may depend on how strongly they are signaled through their own receptors. New research using an animal model ...
Tech Xplore / Engineered wood provides solar power even after the sun goes down
While sustainable solar energy can potentially meet our global power needs, it has one major flaw. When sunlight disappears, solar panels stop generating electricity. The problem is that while they do an excellent job of ...
Medical Xpress / Cardiorespiratory fitness may cut dementia, depression and psychosis risk

Tech Xplore / Fusion power may never be cost-competitive with renewables, study warns
Fusion power plants are sites at which electricity could be generated via a process known as nuclear fusion, which entails the merging of two atomic nuclei into a single heavier nucleus. This process is known to generate ...
Phys.org / Hollow-sphere catalyst enables greener production of 99% pure propane at room temperature
The world's appetite for propene (propylene) is growing faster than the chemical industry can keep up. This petrochemical product powers the production of acrylonitrile, propylene oxide, high-velocity fuels, and, most importantly, ...
Phys.org / A light-controlled 'muscle' could give synthetic cells a new way to move
Engineers interested in creating artificial cells to deliver drugs to unhealthy parts of the body face a key challenge: for a cell-like system to move, change shape, or divide, it needs a way to generate force on command.
