Phys.org / Study finds some microbes drastically change behavior outside the lab
A new study underscores the importance of studying microbes in their natural setting rather than relying solely on laboratory research. Researchers found that a set of corn root bacteria behaved completely differently when ...
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 / 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 / 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 / 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 / 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 / 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 / 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 / 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 ...
Phys.org / Tungsten may suffer more radiation damage in fusion reactors than expected
Fusion reactors, devices that generate energy by fusing light atomic nuclei at extremely high temperatures, could contribute to ongoing efforts aimed at producing electricity more sustainably. The extreme environment inside ...
