Scientists may have solved why the length of Earth’s day changes by a few milliseconds over decades. Subtle shifts in the inner core appear to tug on the mantle, revealing a surprisingly dynamic world...
NASA and SpaceX could launch four astronauts to the International Space Station on October 1, with the Dragon spacecraft reaching orbiting outpost less than nine hours after liftoff. Crew-13 will join...
CosmoCube will use the far side of the Moon as a shield from Earth’s radio noise to search for a faint signal from the universe before the first stars existed. The suitcase-sized satellite could revea...
Yellow-morph green sea turtles in the Galápagos surprised scientists by staying remarkably close to home instead of making the long journeys typically associated with sea turtles. Satellite tracking s...
Scientists have discovered a stem cell that appears to serve as a master source for tendon and ligament cells throughout the body. In lumbar spinal stenosis, these cells become unusually active and ma...
Scientists have discovered a new tick-borne virus in China that causes flu-like illness and may account for previously unexplained cases of fever, fatigue, digestive problems, and low platelet counts....
People with diabetes reported better quality of life after days when their glucose stayed largely within a healthy range, even when levels fluctuated more than usual. The unexpected finding suggests t...
A new study suggests coffee may influence mood and brain function by changing the activity of microbes in the gut. Both caffeinated and decaf coffee were linked to lower stress, depression, and impuls...
Spaceflight may dramatically change the gut within weeks, causing bacteria to break down more protein as food moves more slowly through the intestines. The shift could help explain astronaut constipat...
A beautifully preserved fossil from Mongolia’s Gobi Desert has solved a mystery that puzzled paleontologists for nearly 40 years. Tamirkhan balcarceli shows that zhelestids were not early relatives of...
JWST has revealed that young planetary systems lose their planet-building gas through a changing mix of powerful jets, molecular winds, and radiation-driven outflows. As the disks age and their gas di...
A compound the body can make after eating pomegranates, walnuts, and some berries improved measures of heart function by up to 80% in animal models of a difficult-to-treat form of heart failure. Uroli...
