Capturing the coordinated dance between electrons and nuclei in a light-excited molecule

Using a high-speed "electron camera" at the Department of Energy's SLAC National Accelerator Laboratory, scientists have simultaneously captured the movements of electrons and nuclei in a molecule after it was excited with light. This marks the first time this has been done with ultrafast electron diffraction, which scatters a powerful beam of electrons off materials to pick up tiny molecular motions.

NASA Snow campaign wraps 2020 survey

As spring and summer temperatures return to the Northern Hemisphere, winter's snow is melting, releasing precious fresh water into Earth's streams, rivers and oceans. This annual change provides liquid water for drinking, agriculture and hydropower for more than one billion people around the world. In the future, NASA plans to use a satellite mission to measure how much water the world's winter snowpack contains, and to do that, they need to know what combination of instruments and techniques will efficiently measure this information from space.

Scientists identify chemicals in noxious weed that 'disarm' deadly bacteria

Scientists have identified specific compounds from the Brazilian peppertree—a weedy, invasive shrub in Florida—that reduce the virulence of antibiotic-resistant staph bacteria. Scientific Reports published the research, demonstrating that triterpenoid acids in the red berries of the plant "disarm" dangerous staph bacteria by blocking its ability to produce toxins.

Teleradiology enables social distancing during coronavirus disease (COVID-19) pandemic

Remote reading of imaging studies on home PACS workstations can contribute to social distancing, protect vulnerable radiologists and others in the hospital, and ensure seamless interpretation capabilities in emergency scenarios, according to an open-access article published ahead-of-print by the American Journal of Roentgenology (AJR).

COVID-19 evidence and strategies for orthopaedic surgeons

How should orthopaedic surgeons respond to the COVID-19 pandemic? A review in The Journal of Bone & Joint Surgery analyzes evidence and strategies for managing the novel SARS-CoV-2 virus—including critical lessons from past pandemics.

Low-severity fires enhance long-term carbon retention of peatlands

High-intensity fires can destroy peat bogs and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new Duke University study finds low-severity fires spark the opposite outcome.

Just a little physical activity pays big dividends to high risk breast cancer patients

Results of a comprehensive analysis of exercise and its protective role for high-risk breast cancer patients show that women who exercise not only live longer, but also are more likely to remain cancer-free after their treatment. What's more, the study suggests that even a modest amount of exercise can be beneficial.

New 3-D printing study shows promise for predictive maintenance

Army researchers have discovered a way to monitor the performance of 3-D printed parts, which tend to have imperfections that affect performance in ways traditionally-machined parts do not.

High stress related to coronavirus is the new normal for many parents, says new APA survey

Emerging evidence on genetics of schizophrenia raises hopes for new treatment targets

In recent years, genome-wide association studies (GWAS) have identified many different genetic variants associated with schizophrenia. These genetic discoveries raise the promise of developing urgently needed new treatments targeting the underlying biology and pathophysiology of schizophrenia, according to a special article in the Journal of Clinical Psychopharmacology.

Researchers collaboratively test mask effectiveness to fight spread of COVID-19

In the early weeks of the coronavirus pandemic, masks were in such short supply they were nearly impossible to find. As a result, people began creating substitute masks out of anything possible—scarves, repurposed old T-shirts, even vacuum bags.
