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 / Hollow-sphere catalyst enables greener production of 99% pure propene 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, ...
Medical Xpress / After high school, exercise collapses for one in three young adults as screens and disinterest take over
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 ...
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.
Phys.org / Sulfur-rich Mercury magmas behave differently than Earth's do
Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and sulfur-rich crust. It ...
Medical Xpress / Novel diabetic wound treatment turns cells into manufacturers
Diabetes affects more than 40 million people in the United States, according to the American Diabetes Association. For many, the chronic condition means a lifetime of pain as worsening circulation leads to nonhealing ulcers ...
Phys.org / Wafer-scale 2D magnetic films emerge thanks to a new low-defect growth technique
In a major advance, researchers at the Indian Institute of Science (IISc) have devised a method to grow high-quality 2D magnetic materials (2D-MMs) over centimeter-scale wafers. Earlier approaches in the field were limited ...
Phys.org / Quantum model explains how single electrons cause damage inside silicon chips
Researchers in the UC Santa Barbara Materials Department have uncovered the elusive quantum mechanism by which energetic electrons break chemical bonds inside microelectronic devices—a detrimental process that slowly degrades ...
Phys.org / How tiny voids could make fusion targets more stable under powerful shockwaves
Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the ...
Phys.org / Theoretical models of supernova chemistry overhauled after X-ray data from Perseus Cluster reveal key discrepancies
The Perseus Cluster is a massive galaxy cluster located in the constellation Perseus. It is one of the largest structures in the observable universe, comprising more than a thousand galaxies—equivalent to roughly a thousand ...
Phys.org / This protein-engineering breakthrough generates over 10M data points and turbocharges AI in just three days
Protein engineering is a field primed for artificial intelligence research. Each protein is made up of amino acids; to optimize a protein function, researchers modify proteins by switching out one of 20 different amino acids ...
