Fragmentary bones from Brazil reveal a new Triassic reptile close to the lineage that preceded dinosaurs and crocodiles. Some 240 million years ago, long before dinosaurs dominated the land and modern crocodiles emerged, their distant relatives were undergoing a crucial stage of evolution. Fossils found in Brazil’s Rio Grande do Sul state have now revealed […]
190-Year-Old Museum Specimen Solves a Pangolin Mystery
New DNA analysis and a reconstructed family tree could help protect it from poaching. On a museum shelf in London, a pangolin specimen collected nearly 190 years ago held genetic evidence that could change how conservationists track one of the world’s most heavily trafficked mammals. Pangolins are medium-sized mammals found only in Africa and Asia. […]
Scientists Built a Programmable Chip That Can Slow Light on Command
New technology enables light to be stored, delayed, and controlled within a single photonic chip, with potential applications in low-power optical computing for AI servers and next-generation optical communication systems. Light moves quickly enough to transmit enormous amounts of information, but that speed creates a problem when a computer needs to hold, delay, or synchronize […]

Astronomers Detect an Atmosphere on a Potentially Earth-Like World
This discovery marks a major milestone in the search for life on worlds beyond our solar system. A faint stream of helium escaping from a distant rocky world has revealed something astronomers had never clearly detected before: an atmosphere around an Earth-like planet in another star’s habitable zone. The result is the strongest evidence so […]
The Backyard “Silly Sprinkler” That Cracked One of Physics’ Biggest Puzzles
Quirky backyard sprinklers helped scientists solve a decades-old mystery about how flowing water makes objects spin. Every summer, lawns across the country come alive with “silly sprinklers,” colorful devices with looping and spiraling tubes that send water spraying in unexpected patterns. Although they may look like simple backyard toys, mathematicians have now used their unusual […]
Magnetic Nanoparticles Restore Movement in Mice With Parkinson’s-Like Symptoms
Researchers have developed a magnetic method for influencing deep-brain circuits without permanently implanted electrodes. A magnetic field may offer a new way to reach circuits buried deep within the brain without permanently implanting electrodes. An international research team injected magnetic nanoplatelets into a targeted brain region and used them to improve movement problems in mice […]
