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 ...

Astronomers from the George Washington University (GWU) in Washington, DC, and elsewhere have employed NASA's Chandra X-ray spacecraft to observe a pulsar wind nebula inside a supernova remnant known as CTA 1. Results of ...

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 ...

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, ...

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 ...

A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line.

University of Calgary researchers are a part of a group who just got one step closer to solving a mystery of the universe. Dr. Timothy Friesen, Ph.D., an associate professor of Physics and Astronomy in the Faculty of Science, ...

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 ...

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 ...

New research reveals a potential link between the gut microbes of a fish and global ocean processes, offering new insight into how marine ecosystems help regulate ocean chemistry and the marine carbon cycle. The study, titled ...

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.

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 ...
