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 ...

Drugs designed to clear amyloid beta from the brain--once seen as a promising path to slowing Alzheimer's--may not actually help patients in any meaningful way, according to a major review of over 20,000 participants. Even more concerning, they may . ...

Evolution seems to follow a script more often than expected. Researchers found that distantly related butterflies and moths have reused the same pair of genes for over 120 million years to produce strikingly similar warning colors. Rather than ...

Coffee doesn't just energize--it actively reshapes the gut and mind. Researchers found that both caffeinated and decaf coffee altered gut bacteria in ways linked to better mood and lower stress. Decaf even improved learning and memory, while caffeine ...
