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. ...

Scientists are using sunlight to turn plastic waste into clean fuels like hydrogen, offering a breakthrough solution to both pollution and energy challenges. While still in development, the approach could transform trash into a valuable resource for ...

For decades, relaxor ferroelectrics have powered everything from medical ultrasounds to sonar systems, yet their inner atomic structure remained a mystery--until now. Researchers have finally mapped their three-dimensional structure in unprecedented ...

After centuries of mystery, scientists are edging closer to uncovering Leonardo da Vinci's biological secrets. A massive 30-year effort has mapped his family across 21 generations, identified living male descendants, and even confirmed shared DNA ...

Artemis II proved NASA's deep space systems are ready for the next leap. Orion survived its high-speed return with improved heat shield performance and pinpoint landing accuracy, while the SLS rocket nailed its trajectory. Even the launch pad ...

Voyager 1 just powered down a nearly 50-year-old instrument to stay alive in deep space. The spacecraft is running critically low on energy, forcing NASA to make careful sacrifices to keep its mission going. Despite the shutdown, it continues to send ...

Creatine might be famous in the gym, but its real story is far more interesting. Naturally produced in the body, it helps power cells by rapidly regenerating ATP--the fuel that keeps muscles, the brain, and even the heart running during intense ...

A new study suggests depression may soon be detectable through a simple blood test--by tracking how certain immune cells age. Researchers found that accelerated aging in monocytes, a type of white blood cell, is closely tied to the emotional and ...

GLP-1 drugs like semaglutide--best known for treating diabetes and driving weight loss under the brand names Ozempic and Wegovy--may also deliver a surprising mental health boost. In a massive study tracking nearly 100,000 people over more than a ...
