Detecting water where none remains today: Neutron and X-ray tomography make it possible. In an international study conducted with the participation of the Paul Scherrer Institute PSI, researchers have brought to light macroscopic ...
Phys.org / Magnetic mystery in thorium clusters resolved by new study
Scientists from the University of Manchester's Department of Chemistry, Centre for Radiochemistry Research and Photon Science Institute, led by Professor Steve Liddle, have uncovered why a rare class of metal clusters appears ...
Phys.org / Historical DNA reveals largetooth sawfish have lost much of their genetic diversity
The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past century and a half, according to a study published in the Proceedings of the Royal Society B: Biological ...
Phys.org / Hurricane Hunter data reveal early signs of strengthening tropical cyclones
Before tropical cyclones can significantly strengthen, they generally must first become vertically aligned, with their rotating centers stacked through the atmosphere. New research using nearly three decades of NOAA Hurricane ...
Medical Xpress / Astrocytes directly regulate brain circuits that consolidate memories during sleep, study reveals
Research has shown that a good night's sleep has many benefits, including memory consolidation. How sleep enables the brain to strengthen memories is still not completely understood, but a new study published in Neuron reveals ...
Medical Xpress / Brain inflammation may cast a long dementia shadow in older survivors of encephalitis
Encephalitis is a serious condition in which an infection or autoimmune response triggers inflammation of the brain. The resulting swelling can disrupt normal brain function, causing neurological changes such as confusion, ...
Medical Xpress / Selenite changes key properties of pancreatic cancer cells in experimental models
Researchers at Karolinska Institutet report in the Journal of Experimental & Clinical Cancer Research that sodium selenite not only can damage tumor cells but also influence characteristics linked to tumor aggressiveness ...
Phys.org / Unfamiliar with rattlesnakes, blackbirds still avoid striking them while defending nests
In a rare study of snakes as nest predators, scientists found nesting birds were loath to strike rattlesnakes even though they likely had no previous experience with vipers.
Phys.org / Beyond the algorithm, online negativity takes on a life of its own as users try to stand out
It doesn't take a scientist to figure out that social media can trend toward the negative. But it might take one to figure out why. In a new paper in PNAS, professor of psychology Joshua Conrad Jackson and colleagues show ...
Medical Xpress / Ketamine and psychotherapy show promise as a combined approach to chronic neuropathic pain
Combining ketamine and psychotherapy is a safe and feasible approach with promising benefits for people experiencing chronic neuropathic pain, according to a new study by researchers at St. Michael's Hospital, the University ...
Medical Xpress / A novel intervention to potentially improve the outcome of children with malnutrition
Researchers at Baylor College of Medicine and Texas Children's Hospital have uncovered an intervention that could potentially improve outcomes for children with malnutrition, a condition that contributes to nearly half of ...
Phys.org / Four hazards converge in East Portland, where underinvestment deepens vulnerability
When it comes to compounding natural hazards like landslides, wildfires, flooding and extreme heat, where you live makes all the difference. New research from Portland State University underscores this disproportionate reality, ...
