Researchers can spot signs of a newly identified genetic eye disease before light-sensing cells are lost by measuring how vision recovers in darkness. People with a newly identified genetic eye condition can see well for most of their lives before gradually losing peripheral vision and struggling to see at dusk or at night. The condition […]
A New Fiber Supplement Could Be a Game Changer for Millions With IBS
For people with IBS, a specially designed fiber blend could support a healthier gut without added pain or bloating, a trial alongside a low-FODMAP diet suggests. Cutting out foods that leave you bloated or in pain can bring welcome relief. For millions of people with irritable bowel syndrome, or IBS, however, a diet that eases […]
Could a Nasal Spray Stop Alzheimer’s Before Memory Loss Begins?
Protecting memory from Alzheimer’s may one day involve a nasal spray, with encouraging results in animals and evidence that its particles also protect human neurons grown in the lab. Alzheimer’s disease damages the connections that allow brain cells to communicate, threatening memory. A nasal spray containing tiny particles naturally released by cells has helped protect […]

NASA Space Telescope Meets Fiery End After Nearly 22 Years in Orbit
NASA’s Neil Gehrels Swift Observatory has returned to Earth after spending nearly 22 years in space, bringing an extraordinary mission of cosmic discovery to an end. The spacecraft reentered Earth’s atmosphere on Wednesday, more than two decades after launching in 2004. Swift was a pioneering space observatory equipped with three telescopes capable of detecting different […]
NASA’s Perseverance Mars Rover Just Drove Farther Than Any Vehicle Beyond Earth
NASA’s self-driving Perseverance rover has broken the all-time off-world driving record and is now exploring ancient Martian terrain that could hold clues to the Red Planet’s long-lost history. NASA’s Perseverance rover has set a new record for driving on another world, traveling farther across the surface of Mars than any vehicle in history. On October […]
Look Up: Three Meteor Showers, a Supermoon, and a Historic Space First Are Coming in November
November offers plenty of reasons to look up, including the Taurid and Leonid meteor showers, a close pairing of Mars and Jupiter, a remarkable milestone for NASA’s Voyager 1 spacecraft, and a bright supermoon. November Skywatching Highlights Around November 5: The Southern Taurid meteor shower reaches its peak, with the possibility of unusually bright fireballs. […]
Scientists Finally Crack a 1,600-Year-Old Roman Glass Mystery
More than 1,600 years after the Romans created the famous Lycurgus Cup, a University of Sheffield technician has found a way to reliably reproduce its extraordinary color-changing glass. A glass cup made more than 1,600 years ago has puzzled historians and glassmakers for centuries. When light reflects off its surface, the cup appears jade green. […]
Scientists Discover Something Unexpected 90 Kilometers Beneath Earth
A rock from Papua New Guinea was hotter than expected during its descent into Earth, challenging models of a process that influences earthquakes, volcanoes, and climate. Earth recycles its own surface. In regions called subduction zones, one tectonic plate, a vast slab of Earth’s outer shell, sinks beneath another as the plates collide. These zones […]
Popular Dairy Alternatives Could Be Leaving You Short of Essential Nutrients
A new study reveals that even partially replacing dairy products with plant-based alternatives could significantly reduce the intake of essential nutrients. Replacing even a modest amount of dairy with plant-based alternatives could significantly reduce essential nutrient intake, according to a new study from the University of Surrey. Researchers found that substituting just 20% to 35% […]
