Phys.org / Fulfilling friendships linked to better health and well-being across 22 countries
Fulfilling friendships and close social relationships are strongly linked to excellent physical and mental health, finds a substantial global study published in the Journal of Mental Health.
Phys.org / Theoretical framework expands directional light control beyond ordered crystal structures
A research team has developed a new theoretical framework that can suppress light scattering in certain directions while enhancing it in others, even in irregularly arranged materials. The work extends research on controlling ...
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 / More than half of hippocampal synapses vanish, yet mouse memories remain intact
How do we remember the distant past? For decades, scientists have believed synaptic potentiation—the adaptive strengthening of our brain's cellular connections—to be the key to memory retention. Researchers from the Okinawa ...
Phys.org / Climate change decided who ruled as top predator 35 million years ago
An international team of researchers from Belgium, France, Switzerland, Spain and the U.S. has reconstructed the evolution of body mass in carnivorous mammals during the Paleogene—a crucial window in the diversification of ...
Phys.org / Cosmic filaments help set first limits on dark matter's decay into gravitons
Composing some 85% of the universe's total mass, dark matter betrays its presence only through gravity, unlike ordinary matter. Yet through new research published in Physical Review D, a team led by David Dunsky of New York ...
Phys.org / First evidence of Neanderthal bone tool use in Romania discovered
Deep in the Vârghiș Gorges, tucked away in the dark recesses of a cave, researchers have found the first evidence that Neanderthals used bone tools in Romania.
Medical Xpress / Always finish your antibiotics? Longer is better? Outdated ideas about antibiotics are common, study says
"Always finish your antibiotics" is no longer considered medical best practice for all conditions. Surprised? You're not alone.
Phys.org / Mutation hotspots help 'friendly' viruses outmaneuver the bacteria in your gut
Every 15 minutes, someone in the U.S. dies from a drug-resistant superbug. A few decades from now, antibiotic-resistant bacterial infections threaten to become the leading cause of death worldwide, outpacing cancer.
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 / Breast cancers can recruit bone cells to increase tumor growth
Researchers at WashU Medicine have shown that cells originating in bone and best known for their role in bone formation are recruited to primary breast tumors, where they become cancer-associated fibroblasts, a type of cell ...
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.
