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 ...
Medical Xpress / Emotion-regulation training reduces distress and changes the brain, team reports
A five-week training intervention taught college students to better regulate their emotions in response to negative events, a new study finds. After the training, the students reported less emotional distress when viewing ...
Phys.org / Scientists 'see' nanoscale forces, providing evidence of electric fields at the air‑water interface
Bubbles are round, and we know surface tension does that. But squeeze that gas-liquid boundary into a space only a few tens of nanometers wide—could other forces be at work?
Medical Xpress / Women make up nearly 70% of the global health workforce, even as the world faces a shortage of 34 million health workers
Women have driven the expansion of the global health workforce over the past three decades, yet substantial workforce shortages remain, according to a new study published in The Lancet Public Health. Researchers estimate ...
Medical Xpress / Tsimané and Moseten peoples of lowland Bolivia demonstrate an intriguing case of epidemiological resilience
Despite widespread COVID-19 infection in the Tsimané and Moseten populations of Bolivia, the mortality rate in these remote Indigenous groups was the lowest ever recorded for any population or region.
Phys.org / 'Hidden stars' suggest that distant galaxies are much more massive than they appear
Astronomers have discovered that the most massive galaxies in the early universe contain far more small stars than expected. As a result, these early galaxies were likely much more massive than initial measurements suggested. ...
Phys.org / A single asteroid impact may explain the appearance of Mars' moon Deimos
Deimos, the smaller and outermost of Mars' two moons, is roughly oval in shape and has a deep depression at its south pole. Unlike its heavily scarred sister moon, Phobos, Deimos is covered by a loose layer of dust and rubble—a ...
Phys.org / Strain flips Hall signal in altermagnetic manganese telluride, suggesting a path to practical spintronics
Time-reversal symmetry is an exotic behavior found in systems whose internal physics looks different when running forward versus backward in time. For some time, physicists have searched for this behavior in systems with ...
Medical Xpress / Why you move—not just how often—could affect dementia risk
For years, scientists have known that regular physical activity can help lower the risk of dementia. But new USC research suggests that it's not only the amount but also the activity's context—for work or for leisure—that ...
Phys.org / Model siblings: Adolescent coping strategies influenced by birth order, study shows
Growing up as the oldest sibling of a younger brother and sister shaped the way University of Delaware associate professor Mellissa S. Gordon learned to communicate and cope with challenges. As a single parent, her mother ...
Tech Xplore / Engineers connect bacteria to create living transistors
MIT researchers have engineered bacteria that can function as transistors, allowing the team to create living "circuit boards" that can be printed onto a growth medium in a Petri dish.
Phys.org / Shackled men in 2,600-year-old Greek mass graves were likely locals, archaeologists find
In 2016, archaeologists working at the Phaleron Burial Ground, part of the ancient Attica region, uncovered an astonishing sight: three mass graves dating to the 7th and 6th centuries BCE containing the skeletons of 79 adult ...
