Researchers at Stanford have developed a compact optical amplifier that dramatically boosts light signals using very little power. By recycling energy inside a looping resonator, the device achieves strong amplification with minimal noise and wide .. ...

Astronomers have spotted something surprising in the far outer Solar System--a faint, short-lived atmosphere clinging to a tiny icy world that shouldn't be able to hold one at all. The object, called 2002 XV93, is far smaller than Pluto, yet ...

Scientists have developed a breakthrough injectable biomaterial that travels through the bloodstream to repair damaged tissue from within, reducing inflammation and jumpstarting healing. In animal studies, it successfully treated heart attack damage ...

GLP-1 weight-loss drugs like Ozempic and Wegovy are often celebrated as game-changing solutions--but new research reveals a surprising social twist. People who lose weight using these medications may actually face more judgment than those who lose .. ...

Tyrannosaurs may be famous as fearsome apex predators, but new research reveals a more opportunistic--and slightly grim--side to their behavior. Using high-resolution 3D scans, a researcher identified precise bite marks on a massive tyrannosaur foot ...

Long-forgotten ancient tablets have been decoded, uncovering a mix of magic, politics, and daily life from early civilizations. Among the discoveries are rare anti-witchcraft rituals meant to protect kings and a regnal list that could point to the .. ...

A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don't exist under normal conditions. By carefully "driving" materials with timed magnetic shifts, researchers created ...

A new study suggests travel could be a surprisingly powerful anti-aging tool. By viewing tourism through the lens of entropy, researchers found that positive travel experiences may help the body stay balanced and resilient. Activities like exploring ...

A new study suggests a surprisingly simple compound could help fight Alzheimer's disease. Researchers found that arginine--an inexpensive amino acid already considered safe--can reduce the buildup of toxic amyloid proteins in the brain, a hallmark of ...

Greenland's ice sheet is now melting in ways never seen before, with extreme events becoming more frequent, widespread, and intense. Since 1990, meltwater production has skyrocketed, and most record-breaking events have occurred in recent years. ...
