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 / 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 / Early hardship may shape how oxytocin influences altruism
While humans are inherently social beings, they can interact and connect with others in very different ways. For instance, while some people tend to be more altruistic, others are less prone to helping their friends, acquaintances ...
Phys.org / Copper's surprising melting behavior provides insights into future fusion design
Future fusion power plants aim to recreate the heart of a star here on Earth to power our future energy needs. While the core fusion plasma will burn at hundreds of millions of degrees, the surrounding structural components ...
Medical Xpress / States enact emergency orders on kratom while awaiting federal rules
States are moving faster and further than federal regulators to get kratom off store shelves, with some banning the herb outright while a pending federal rule targets only one of its chemicals.
Phys.org / Stellar explosions come into focus with new nuclear reaction measurements
In two separate papers published in Physical Review Letters, researchers investigated the nuclear reactions that take place inside supernovae and X-ray bursts—two of the universe's most powerful explosions. Together, the ...
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 / Brain receptors may act as biological brakes on chronic pain after nerve injury
Deep at the base of the brain, a tiny cluster of nerve cells serves as the body's natural pain reliever, dialing down pain signals traveling up the spinal cord. But nerve damage can flip this system into a hyperactive engine ...
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 / World off-track on nearly every food system goal, latest assessment reveals
The latest study from the Food Systems Countdown Initiative (FSCI) reveals the stark reality of where global food systems transformation stands: for most indicators on health, environment, livelihoods, governance and resilience, ...
Medical Xpress / Flexible brain circuits can switch between different tasks
As we move through everyday life, our brains engage in a huge variety of cognitive tasks. For example, during a grocery run, we might have to recall the items for a recipe, remember where the clerk said the flour was located ...
Phys.org / Two eyeless shrimp-like species found in Japan's groundwater are new to science
Researchers have identified two new species in the genus Bogidiella, small shrimp-like amphipods that live in subterranean aquatic environments, from cave waters on the Ryukyu Islands, a subtropical island chain in southwestern ...
