Medical Xpress / Newly found immune cells link strep throat to psoriasis
A common strep throat infection can trigger guttate psoriasis by altering the behavior of key immune cells, according to a new study from Karolinska Institutet published in eBioMedicine. The findings suggest how an infection ...
Phys.org / Impact-formed glass provides evidence of cosmic collision in Brazil about 6 million years ago
For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth's surface. These structures, named geraisites ...
Phys.org / New catalyst unlocks aluminum's ability to switch between oxidation states
Aluminum's journey has been remarkable, going from being more expensive than gold to one of the most widely used materials, from beverage cans to window frames and car parts. Scientists from the Southern University of Science ...
Phys.org / Is teasing playful or harmful? It depends on a number of factors
Picture this: A group of girls are sitting at a table in the lunchroom when a boy walks by. One girl turns to another girl and laughingly says, "Oh, isn't that your boyfriend? You should go kiss him!"
Phys.org / How one genome creates two distinct fungal bodies
Creatures that can change from one form to another are a staple of science fiction: Think werewolves and Transformers. Nature, too, has its shapeshifters, such as dimorphic fungi. While scientists have known for some time ...
Phys.org / NASA moon rocket hit by new problem, putting March launch with astronauts in jeopardy
NASA's new moon rocket suffered another setback Saturday, putting next month's planned launch with astronauts in jeopardy.
Phys.org / Quantum trembling: Why there are no truly flat molecules
Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a ...
Medical Xpress / Intermittent fasting doesn't have an edge for weight loss, but might still work for some, research shows
Intermittent fasting has become a buzzword in nutrition circles, with many people looking to it as a way to lose weight or improve their health.
Phys.org / Phonon lasers unlock ultrabroadband acoustic frequency combs
Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency combs, which consist of equally ...
Medical Xpress / Why chronic pain lasts longer in women: Immune cells offer clues
Chronic pain lasts longer for women than men, and new research suggests differences in hormone-regulated immune cells, called monocytes, may help explain why.
Phys.org / Nanoengineers realize an on-chip excitonic hyperlens
When light passes through materials, it typically changes direction and bends in predictable ways. This change in direction, known as refraction, is caused by a change in the speed of light as it enters a new medium. In some ...
Phys.org / Massive ceramics haul from a 14th-century shipwreck reveals Singapore's trading past
Singapore was a thriving trading hub hundreds of years before popular narratives depicted it as a quiet fishing village, according to a study of the cargo of a centuries-old shipwreck. Sometime during the middle of the 14th ...
