Scientists studying thousands of rats discovered that gut bacteria are shaped by both personal genetics and the genetics of social partners. Some genes promote certain microbes that can spread between individuals living together. When researchers ...

More than 200 years ago, Count Rumford showed that heat isn't a mysterious substance but something you can generate endlessly through motion. That insight laid the foundation for thermodynamics, the rules that govern energy, work, and disorder. Now, ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University of Iowa researchers found that unwanted photons produced by lasers can be canceled out by carefully tuning the light itself. ...

Scientists at MIT and Stanford have unveiled a promising new way to help the immune system recognize and attack cancer cells more effectively. Their strategy targets a hidden "off switch" that tumors use to stay invisible to immune defenses--special ...

Scientists exploring Romania's Haeg Basin have discovered one of the densest dinosaur fossil sites ever found, with bones lying almost on top of each other. The K2 site preserves thousands of remains from a prehistoric flood-fed lake that acted like ...

A deadly hospital fungus that resists nearly every antifungal drug may have an unexpected weakness. Researchers discovered that Candida auris activates specific genes during infection to hunt for nutrients it needs to survive. This insight came from ...

A new imaging technology can distinguish cancerous tissue from healthy cells by detecting ultra-weak light signals. It relies on nanoparticles that bind to tumor markers, making cancerous areas easier to identify. The system is far more sensitive ...

When we watch someone move, get injured, or express emotion, our brain doesn't just see it--it partially feels it. Researchers found eight body-like maps in the visual cortex that organize what we see in the same way the brain organizes touch. These ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction--an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in this atomic system reveals a deep universality in ...

Your eyes may reveal when your brain is working overtime. Researchers found that people blink less when trying to understand speech in noisy environments, especially during the most important moments. The effect stayed the same in bright or dark ...
