Phys.org / Einstein Probe catches rare X-ray flash from an exploding star

Astronomers have linked an X-ray flash discovered by the Einstein Probe to a known type of supernova with unusual features that point to the birth of an ultra-dense, rapidly spinning magnetar. The paper outlining this finding ...

Phys.org / Centuries-old physics test could help detect millicharged particles

Theoretical physicists have long predicted the existence of millicharged particles (mCPs), hypothetical particles that carry a very small electric charge. These particles are expected to interact very weakly with ordinary ...

Phys.org / Active particles could make stable glasses stronger without catastrophic brittle failure

The strongest glasses have an Achilles' heel that causes them to fail catastrophically when pushed past their limit. They do not bend or stretch, as all damage concentrates into a single plane and the material fails in an ...

Phys.org / Black hole star: Astronomers discover a brand-new type of astrophysical object

Astronomers at MIT and elsewhere have spotted an extremely bright red spot in the early universe. The object resembles an enormous star, roughly the size of our solar system. But it also is putting out 100 billion times more ...

Medical Xpress / Wearable smart patch could automatically deliver aid during a fentanyl overdose

A patch smaller than a penny could one day save the lives of people experiencing a fentanyl overdose—even when no one else is there to help. Researchers in Virginia Tech's Department of Biological Systems Engineering have ...

Phys.org / Why AI training can backfire for older workers

Employers are increasingly investing in training to prepare their employees for artificial intelligence (AI). Training budgets are growing, and "upskilling" has become a common response to rapid technological change.

Medical Xpress / Trouble focusing when upset may signal anxiety and depression symptoms in youth

How a child focuses when upset is far more revealing about their mental health than how they focus when calm, according to FIU psychologists. In a new study published in Journal of Psychopathology and Behavioral Assessment, ...

Phys.org / Topical clove oil for canine sarcoptic mange promises faster, plant-based treatment

Canine sarcoptic mange (scabies) is a skin condition in which microscopic mites (Sarcoptes scabiei) infest dogs' skin. The condition is contagious and zoonotic and can be difficult to detect. If left untreated, it can cause ...

Phys.org / Early-universe plasma may have stopped dark photons from heating cosmos

A new paper published in Physical Review Letters reveals that a leading dark matter candidate—the hypothetical "dark photon"—would not have heated the early universe as previously thought. The finding opens a vast region ...

Phys.org / Neptune's tiny moons tell the story of Triton's destructive capture

Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all ...

Medical Xpress / New obesity definitions reveal ill health more accurately than body mass index

Traditionally, obesity has been classified primarily using BMI, a measure of weight relative to height that provides limited information about whether excess fat is actually affecting a person's health. BMI levels have historically ...

Medical Xpress / High-speed microscopy reveals electrical activity across the brain

Within the brain, neurons compute by generating electrical impulses. These signals travel throughout neurons, which are in turn connected in vast networks that control brain functions such as sensory perception, memory formation ...
