Problematic use of marijuana among adolescents and adults increased after legalization of recreational marijuana use, according to a new study from NYU Grossman School of Medicine and Columbia University Mailman School of Public Health.Researchers developed a tool called Geneva (short for Genetic Evasion), which automatically learns to circumvent censorship. Tested in China, India and Kazakhstan, Geneva found dozens of ways to circumvent censorship by exploiting gaps in censors' logic and finding bugs that the researchers say would have been virtually impossible to find manually.A new video game framework brings together two well-studied approaches to educational software in order to keep multiple players engrossed in the learning experience while fostering collaboration and problem solving. The framework is one of the first to integrate narrative-centered learning and collaborative learning techniques, laying the groundwork for future efforts in the field.Bitcoin, Ethereum, Litecoin and Monero -- the names of digital-based 'cryptocurrencies' are being heard more and more frequently. But despite having no physical representation, could these new methods of exchange actually be negatively impacting our planet? It's a question being asked by researchers who are investigating the environmental impacts of mining cryptocurrencies.A research collaboration has achieved exaflop performance with a deep learning application used to model subsurface flow in the study of nuclear waste remediation.A new study which combines measurements from nearly 1,400 drinking water wells across North Carolina estimates that more than half of the wells in the state's Piedmont region contain levels of cancer-causing hexavalent chromium in excess of state safety standards. The prediction is based on a model of geology and chemistry.One million species are threatened with extinction, many of them already in the coming decades. This unprecedented loss of biodiversity threatens valuable ecosystems and human well-being. But what is holding us back from putting conservation research into practice?New research has explored the growing uncertainty faced by children aged 0-8 years in disaster zones, such as bushfires, finding that early childhood teachers hold a vital role in supporting children dealing with trauma.A child's temperament appears to be affected by the early stages of their life. Researchers have found children who were born very preterm (under 32 weeks gestation) or very low birthweight (under 1500g) had similar temperamental difficulties in controlling their impulses, to children who experienced institutional deprivation.Children who experience maltreatment, such as neglect or physical or sexual abuse, are more likely to engage in delinquent and offending behaviors in adolescence and young adulthood, according to a new study.Scientists argue that public debate about the role of soil carbon in battling climate change is undermining the potential for policymakers to implement policies that build soil carbon for other environmental and agricultural benefits.The implementation of the 2013 American College of Cardiology/American Heart Association Guideline on the Treatment of Blood Cholesterol has been linked to improved overall cholesterol levels for American adults, especially those on cholesterol lowering medications, according to a new study.In research that validates what many parents and educators suspect, students whose grades are below average could boost their exam results if they devoted less time to Facebook and other social networking sites.New research reveals that brand-name drug discount cards are leading to higher health care spending in Canada -- increased costs that are ultimately passed on to patients.Mosquito nets designed to prevent malaria transmission are used for fishing which may devastate tropical coastal ecosystems, according to a new scientific study. The researchers found that most of the fish caught using mosquito nets were smaller than a finger and potentially collect hundreds of individuals.Free Internet access must be considered as a human right, as people unable to get online -- particularly in developing countries -- lack meaningful ways to influence the global players shaping their everyday lives, according to a new study.New research comprehensively examined the brain development of young boys and girls. Their research shows no gender difference in brain function or math ability.A new study suggests that such conflicts of interest disclosures have no impact on journal reviewers, even when the authors of submitted papers did, in fact, report conflicts. The study also found that reviewers' evaluations of different facets of research quality, such as methods, conclusions and objectivity, were similarly unaffected by COI disclosures.The US economy will continue to expand for a 12th consecutive year in 2020, but by only about 2% and struggling to remain at that level by year's end. Indiana's economic output will be more anemic, growing at a rate of about 1.25%, according to a forecast.Scientists from a variety of fields highlight key ways institutions and funding agencies can help address sexual harassment and gender bias in the STEM workplace.
