Is Sparkling Water Bad for Your Teeth? New Research Has a Clear Answer
A new wave of studies finds that plain, unflavored sparkling water does not meaningfully damage tooth enamel under typical drinking conditions—but flavored and sweetened carbonated varieties are a different story.
Brain Hits a Biological Phase Shift Between 50 and 75, Study Finds
Researchers at the New York Genome Center used single-cell RNA sequencing to discover that the brain undergoes a concentrated biological phase transition between ages 50 and 75, driven by a dramatic shift in its immune cell population — a finding that challenges decades of neuroscience.
Ancient Shipwreck With 650 Amphorae Found Intact Off Andros After 2,400 Years
A 2,400-year-old merchant vessel carrying an estimated 600 to 650 intact amphorae has been discovered on the Aegean seabed off the Cycladic island of Andros, Greece's Ministry of Culture announced — one of the most significant ancient shipwreck finds in the region in recent years.
Falcon 9 Reaches Orbit in 9 Minutes: How 24 Starlink Satellites Are Deployed
Every Starlink launch from Vandenberg's SLC-4E follows the same compressed arc: nine minutes from ignition to 24 satellites circling Earth at 17,500 mph. The Starlink 17-52 mission — SpaceX's 90th in this operational context — reveals why polar orbits demand California's coast and what happens physically during that ascent.
How Snakes Lost Their Legs: An 80-Million-Year-Old Fossil Shows the Transition
A rare 80-million-year-old fossil preserves the anatomical blueprint of snake limb loss in unprecedented detail, showing which structures had already disappeared and which skeletal hallmarks of modern snakes were already in place — offering the clearest window yet into how lizards became snakes.
Eight Months in Space Ages Astronaut Bones a Decade — Half Never Fully Recover
A NASA astronaut and two cosmonauts returned to Earth after 241 days on the ISS, capping a mission that reveals how long-duration spaceflight compresses roughly a decade of skeletal aging into six months — with bone loss that, in half of studied astronauts, had not fully reversed even a year after landing.Load More
