Phys.org / Who's watching who? Otters turn their attention to humans
For many people, a trip to the zoo is a chance to watch playful otters dart through the water and chatter with one another. But while we may worry that crowds could stress the otter community, a new Australian study shows ...
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 / 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 ...
Phys.org / Mega-Earth GJ 523b is 23 times as massive as our planet—but only 2.5 times as wide
It's nearly 170 million years old. It's more than 2.5 times the size of Earth. And it's the first exoplanet discovered and cataloged by researchers with the Wisconsin Center for Origins Research (WiCOR).
Phys.org / 35-year monitoring study clarifies ecological forces behind Lyme disease risk
Tick-borne diseases are on the rise in the United States. Lyme disease is the most commonly reported, with nearly half a million people diagnosed each year. Caused by the bacterium Borrelia burgdorferi, it is most often spread ...
Phys.org / Gluons may play a central role in baryon number conservation—and matter's stability
New results from the STAR detector at the Relativistic Heavy Ion Collider (RHIC) suggest that gluons, the glue-like particles that hold quarks together inside protons, play a central role in the conservation of baryon number—an ...
Medical Xpress / Hidden immune environment uncovered in thymuses of myasthenia gravis patients
Northwestern Medicine scientists have uncovered a previously hidden immune environment in the thymus that may help drive myasthenia gravis (MG), a chronic autoimmune disease that causes muscle weakness and fatigue, mainly ...
Medical Xpress / Adults 75 and older who stopped statins had similar three-year survival, trial finds
Stopping statins in adults 75 and older with no history of heart disease or stroke does not increase the risk of death over three years compared with continuing statins, although "bad" cholesterol rose around 50% in those ...
Phys.org / Pesticides make Argentine ants go crazy, sending them roaming or clustering before workers die
Don't assume an uptick in ant activity after setting out pesticide traps means the treatment failed. New UC Riverside research shows their behavior changes as chemicals make their way through a colony.
Phys.org / Red blood cells inspire next-generation therapeutic nanocarriers
Red blood cells serve as the foundation for nanocarriers that show promise in a new study as effective and efficient vehicles for gene therapy, tumor targeting and other medical treatments. Scientists at The Ohio State University ...
Phys.org / Molecular electromagnetic sensor may enable remote-controlled gene therapy
The deoxyribonucleic acid (DNA) of living organisms contains regulatory elements that control when, where and to what extent specific genes are turned on or off. They can be co-opted to create "gene switches" that hold significant ...
Phys.org / Tiny feet on cells can sense defects and stall migration to heal wounds
Cells travel through the body both individually and in collective groups during development, wound healing and diseases such as cancer. New research from the McKelvey School of Engineering at Washington University in St. ...
