Phys.org / Inside Europe's largest Copper Age tomb, children's bones expose an ancient health crisis hidden for 5,000 years

Nearly 5,000 years ago, respiratory infections, possibly including tuberculosis, were ravaging the children buried at Camino del Molino (CMOL), Spain. The massive circular burial cave carved into rock is Europe's largest ...

Phys.org / Evidence of cosmic-ray acceleration from a nearby supernova remnant

Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football (soccer ball) being kicked ...

Phys.org / Ohio wall lizards overcame genetic bottleneck through rapid population boom, genomes reveal

Non-native wall lizards living in Cincinnati, Ohio, have thrived against the odds thanks to an ability to expand their population more quickly than any inbreeding-amplified harmful genes could weaken their chances for survival, ...

Phys.org / Saturday Citations: Failure to launch; cellular mortality; heavy weather

Highlights from the last week of May, 2026: A key climate tipping point is disrupting the Arctic Ocean food chain (more of a lowlight, I guess). Scuba-diving tourism may not be the benefit to coral reef systems that we once ...

Phys.org / Diamond quantum sensor could reveal elusive altermagnets

For nearly a century, there were two known kinds of magnets. Ferromagnets are the classic magnets that attract metal and keep pictures stuck to the refrigerator. Antiferromagnets hide their magnetism at the atomic scale but ...

Phys.org / Are taxpayers being gaslighted by street lamp charm?

Gas streetlights might look quaint, but researchers at the University of Cincinnati say they are costly, wasteful and release toxic pollutants into the air. In two studies examining their use in Boston, Massachusetts, and ...

Phys.org / Plants hit the brakes on immunity to survive viral infections

When viruses invade a plant, you might expect an all-out immune war. But new research published in Science shows that, much like in humans, too strong an immune response can actually do more harm than good.

Phys.org / Predator-triggered orange tails may help tadpoles survive by redirecting deadly bites

Bright colors in animals are beautiful but often considered risky because they are more obvious to predators. However, conspicuous colors can also serve defensively, signaling toxicity or even luring predators away from more ...
