Horses have a vocal trick no one fully understood until now. Scientists have discovered that when a horse whinnies, it produces two completely different sounds at the same time. One is a deep tone created by vibrating the vocal folds, similar to how ...

Researchers have detected microplastics in nearly all prostate cancer tumors examined in a new study. Tumor tissue contained about 2.5 times more plastic than nearby healthy prostate tissue. Scientists say this is the first Western study to directly ...

More than 40,000 years ago, Ice Age humans were carving repeated patterns of dots, lines, and crosses into tools and small ivory figurines. A new computational study of more than 3,000 of these Paleolithic signs reveals that they were not random ...

After nearly 50 years of failed attempts and scientific speculation, chemists at Saarland University have achieved what many thought might be impossible: creating a long-sought silicon-based aromatic molecule. By replacing carbon atoms in a famously ...

Subtle changes in brain blood flow and oxygen use are closely linked to hallmark signs of Alzheimer's, including amyloid plaques and memory-related brain shrinkage. Simple, noninvasive scans may one day help spot risk earlier--by looking at the brain ...

Deep inside the Milky Way, an invisible force is quietly holding everything together -- its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, revealing surprising twists in how it flows through ...

Scientists have proposed a surprising connection between solar flares and earthquakes. When solar activity disturbs the ionosphere, it may generate electric fields that penetrate fragile fracture zones in Earth's crust. If a fault is already ...

Deep in the Congo Basin, vast peatlands quietly store enormous amounts of Earth's carbon -- but new research suggests this ancient vault may be leaking. Scientists studying Africa's largest blackwater lakes discovered that significant amounts of ...

A newly identified ichthyosaur from the UK's Jurassic Coast is rewriting part of the prehistoric playbook. Nicknamed the "Sword Dragon of Dorset," the three-meter-long marine reptile lived during a poorly understood window of evolution when major ...

Researchers are engineering bacteria to invade tumors and consume them from the inside. Because tumor cores lack oxygen, they're the perfect breeding ground for these microbes. The team added a genetic tweak that helps the bacteria survive longer ...
