[ad_1] Cannabis has been cultivated as an oil-seed and fibre crop for millennia in East Asia. Little is known, however, about the early use and eventual cultivation of the plant for its psychoactive and medicinal properties. Despite being one of the most widely used psychoactive drugs in the world today, there is little archaeological or…
[ad_1] Under the JST-SENTAN program (Development of System and Technology for Advanced Measurement and Analysis, Japan Science and Technology Agency), the joint development team of Prof. Naoya Shibata at the University of Tokyo and JEOL Ltd., has developed a revolutionary electron microscope that incorporates newly designed magnetic objective lenses, and achieved direct, atom-resolved imaging of…
[ad_1] Governments have a wide variety of policy options at their disposal to respond to the growing threat of antimicrobial resistance, but many of these approaches have not been rigorously evaluated, according to a new study published this week in PLOS Medicine by Susan Rogers Van Katwyk of the University of Ottawa, Canada, and colleagues.…
[ad_1] If you’ve ever come out of a bad relationship and decided you need to date someone different from your usual “type,” you’re not alone. However, new research by social psychologists at the University of Toronto (U of T) suggests that might be easier said than done. A study published today in Proceedings of the…
[ad_1] Doctors could soon get some help from an artificial intelligence tool when diagnosing brain aneurysms — bulges in blood vessels in the brain that can leak or burst open, potentially leading to stroke, brain damage or death. The AI tool, developed by researchers at Stanford University and detailed in a paper published June 7…
[ad_1] Increasing severity of sleep-disordered breathing and sleep disruption are associated with epigenetic age acceleration, according to preliminary results of a new study. Results show that each standard deviation increase in the apnea-hypopnea index, a measure of sleep-disordered breathing severity, was associated with the equivalent of 215 days of biological age acceleration. Similarly, each standard…
[ad_1] Researchers from Tokyo Metropolitan University have successfully found two distinct mechanisms by which foams can collapse, yielding insight into the prevention/acceleration of foam rupture in industrial materials e.g. foods, cosmetics, insulation, stored chemicals. When a bubble breaks, they found that a collapse event propagates via impact with the receding film and tiny scattered droplets…
[ad_1] Preliminary results from a new study suggest that sleep disturbances are associated with mental health problems among survivors of a natural disaster even two years after the event. The researchers surveyed survivors two years after the 2010 earthquake in Haiti. Results show that 94% reported experiencing subsequent insomnia symptoms after the disaster. Two years…
[ad_1] Muscle decline caused by ageing and certain diseases could be dramatically slowed by stopping a chain reaction that damages cells, new research shows. The study revealed the previously unknown steps by which dysfunction of mitochondria — the so-called “powerhouses” of cells — harms muscle health and leads to atrophy (wasting away). The research team,…
[ad_1] For birds, differences in personality are a function of both age and experience, according to new research by University of Alberta biologists. The study examined the red knot, a medium-sized shorebird that breeds in the Canadian Arctic and winters in North Western Europe. The researchers studied 90 birds over a two year period, comparing…
