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 […]

This Common Sleep Habit Could Be Making You Gain Weight
Even modest sleep loss may quietly lead to weight gain and raise the risk of chronic disease over time. People who reduced their nightly sleep by about 80 minutes for six weeks gained an average of one pound and spent more time being sedentary, according to researchers at Columbia University Vagelos College of Physicians and […]
World’s First Room-Temperature Quantum Material Sorts Light in an Unprecedented Way
Quantum materials could transform technologies ranging from powerful computers and highly secure communications to advanced energy systems, but one major obstacle has long stood in the way. Most quantum materials reveal their unusual properties only when chilled to temperatures near absolute zero. At room temperature, continual atomic vibrations caused by heat can overpower the fragile […]
