Phys.org / Giant crocodylians dominated the food chain in Miocene South America, fossil evidence suggests
South America was a frightening place during the Miocene. More than 10 million years ago, a vast lake covered much of the continent, home to giant turtles and crocodylians.
Phys.org / Gene-edited beagles produce no detectable major dog allergen, early tests find
Humans love dogs, but petting them can leave some people sneezing and wheezing. About 15% of the world's population lives with a dog allergy, which can increase the risk of hay fever and asthma. The main culprit is Can f ...
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 ...
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 / 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 / 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 ...
Medical Xpress / Students who view more social media use more products that often harbor hormone-disrupting ingredients
Personal care products are among the largest everyday sources of exposure to endocrine-disrupting chemicals, and high school students who follow social media influencers or watch beauty tutorials seem to use considerably ...
Phys.org / Japan aims for the moons of Mars
Japanese scientists are readying a mission to Mars' moons to retrieve samples that may unlock the origins of the solar system and life on Earth, although a rival Chinese mission aims to make it back first.
Phys.org / A small squeeze reveals new clues about an unusual kind of magnet
Researchers at Rice University have found that gently squeezing a crystal of iron sulfide can change two of its unusual properties at the same time: its tiny magnetic signal and the way electricity moves through it. The result ...
Phys.org / Flightless beetles evolved distinct snail-hunting shapes on Japan's largest island
Islands are widely recognized as natural laboratories of evolution. The ocean restricts movement among islands, allowing isolated populations to adapt to different environments and, at times, diverge into new species. However, ...
Medical Xpress / New way to help CAR-T cells fight solid tumors could change cancer treatment
For more than a decade, CAR-T cell therapy has been one of the biggest breakthroughs in cancer medicine. By reprogramming a patient's own immune cells to attack cancer, doctors have produced remarkable results against certain ...
Phys.org / Brief firearm safety talks more than double openness to out-of-home storage
A brief chat about firearm safety can sharply increase willingness among gun owners to consider temporarily storing their firearms outside the home during times of crisis, a step that could help reduce suicide risk, according ...
