Phys.org / Do narcissists ruin relationships over time? A six-year study suggests a more complex pattern
New research from Michigan State University challenges the popular assumption that narcissists gradually damage their relationships over time.
Phys.org / Iridium's hidden surface chemistry may change how hydrogen and chlorine are made
Iridium is a key component in many electrochemical technologies used for chemical transformations. These include producing hydrogen fuel from water, manufacturing chlorine from seawater for use as a disinfectant and extracting ...
Medical Xpress / SARS-CoV-2 delta and omicron BA.2 show clustered spike D614 reversions. What it could mean for surveillance
Researchers from University of Tsukuba and Institute of Science Tokyo have identified nonrandom patterns in the emergence of spike D614 reversions in publicly available SARS-CoV-2 genomic data. Analysis of publicly available ...
Medical Xpress / Intermittent fasting positively affects female hormones in PCOS, study finds
Polycystic ovary syndrome, or PCOS, affects as many as 18% of all childbearing-age women. The condition occurs when a woman's body produces too much of a group of hormones called androgens, chiefly testosterone. Menstrual ...
Medical Xpress / Study reveals sharp vision comes from single cone cells in the fovea
The human eye can see with exceptional detail, allowing people to read fine print, recognize faces across the room, and take in the features in nature. Scientists have long debated how this sharp vision works at the cellular ...
Medical Xpress / The challenge of delivering evidence‑based medicine in children's care
It is easy to overlook the fact that over 90% of medical treatments are not backed by strong evidence. People can find it frustrating—even infuriating—when a review concludes that the evidence for a treatment is too weak ...
Medical Xpress / Longer weekly home-visit rehabilitations linked to improved activities of daily living in older adults
In aging societies, the role of home-visit rehabilitation (HR)—which provides physical, occupational, and speech therapy in patients' homes—is becoming increasingly important for supporting independent living. Although previous ...
Phys.org / The secrets of black holes and the Higgs mass could be hidden in a 7-dimensional geometry
One of the greatest mysteries of modern physics, the "black hole information paradox," might have finally found an elegant solution, and the answer could also reveal the origins of the mass of fundamental particles.
Phys.org / The most pristine star yet found in the known universe
An unusual team of astronomers used Sloan Digital Sky Survey-V (SDSS-V) data and observations on the Magellan telescopes at Carnegie Science's Las Campanas Observatory in Chile to discover the most pristine star in the known ...
Phys.org / Unexplained sky flashes from the 1950s: Independent analysis supports their existence
Historical observations from an observatory in Germany have now independently verified evidence for brief, mysterious flashes of light in the night sky, first picked up by an American astronomical survey in the 1950s. Through ...
Phys.org / Terraforming Mars: Modeling engineered aerosols to warm the planet
Whenever humans arrive on Mars, they're going to find it a difficult place to exist. Mars is cold, with an average surface temperature of -55°C; temperatures can plunge to -125°C with dust storms lasting months; its atmosphere ...
Phys.org / Tiny African fish caught climbing to the top of a 50-foot waterfall
For over half a century, people in Central Africa have told tales of the fish seen climbing waterfalls, but these claims have never been officially confirmed. Now, these fish have finally been caught on camera, studied more ...
