An artificial-intelligence approach created at the University of North Carolina at Chapel Hill Eshelman School of Pharmacy can teach itself to design new drug molecules from scratch and has the potential to dramatically accelerate the design of new drug candidates.
Vermont recently moved to extend the jurisdiction of its juvenile courts from age 18 to 20, and three other U.S. states (Connecticut, Illinois, and Massachusetts) are considering similar proposals. This comes amid growing awareness that 18- to 25-year-olds are a developmentally distinct group that should be treated differently by the justice system. New research examined juvenile justice in Europe, where most countries have special laws or procedures for this age group; the findings can inform U.S. policymakers.
CHAMPAIGN, Ill. -- Seismic waves are helping researchers uncover the mysterious subsurface history of the Tibetan Plateau, possibly lending insight to future earthquake activity in the region.
ANN ARBOR, MI - Nearly a third of older adults have received a prescription for an opioid pain medicine in the past two years, but many of them didn't get enough counseling about the risks that come with the potent painkillers, how to reduce their use, when to switch to a non-opioid option, or what to do with leftover pills, a new poll finds.
BUFFALO, N.Y. - Stimulant medications are an effective treatment for Attention-Deficit/Hyperactivity Disorder (ADHD). In the classroom, parents and teachers say that medications like methylphenidate (MPH) can reduce symptoms and improve behavior.
Although stimulants have been in use for decades to treat ADHD in school-aged children, just how they work hasn't been clear. But the results of a new study in the Journal of Child Psychology and Psychiatry is filling in critical gaps about the role of improved cognitive functions.
The financial costs of flooding in Canada's maritime region could spike by 300 per cent by the end of the century if steps are not taken to address the impacts of climate change.
A study done by researchers at the University of Waterloo looked at the Halifax, Nova Scotia area, a region hard hit by recent riverine flooding. The team, made up economists, geographers and political scientists, merged data on flood probability, climate change and financial payout information from the insurance/re-insurance market and used the information to develop a forecast.
A new drug discovery system allows scientists to specifically target members of an important family of enzymes, called phosphatases, which were previously considered mostly "undruggable".
Scientists from the Medical Research Council (MRC) Laboratory of Molecular Biology, in Cambridge, UK, demonstrated the capabilities of the new system by identifying a molecule that could successfully target a phosphatase to reduce the accumulation of Huntington's disease-associated proteins in the brains of mice.
Findings from a Rochester Institute of Technology study provide further evidence that the outskirts of spiral galaxies host massive black holes. These overlooked regions are new places to observe gravitational waves created when the massive bodies collide, the authors report.
The study winds back time on massive black holes by analyzing their visible precursors--supernovae with collapsing cores. The slow decay of these massive stars creates bright signatures in the electromagnetic spectrum before stellar evolution ends in black holes.
A plant's defense systems help each other. When one system fails, another one can - at least in part - take over.
Researchers at the Norwegian University of Science and Technology 's (NTNU) Department of Biology have been collaborating with colleagues from Imperial College London and The Sainsbury Laboratory to discover more about how plants defend themselves. Their results have been published in the 26 June 2018 issue of Science Signaling.
Identifying the danger
Scientists at the U.S. Department of Energy's Ames Laboratory have discovered an earlier unknown discontinuous magnetoelastic transition in a rare-earth intermetallic. The mechanism of the material's changing magnetic state is so unusual, it provides new possibilities for discovery of similar materials.
Materials that possess magnetoelastic phase transitions are highly sought after for a number of developing technologies, including caloric heating and cooling systems. Materials that display this property are rare, and are thought to be exclusively transition metal-based.
