A drug already used for osteoporosis blocked spinal damage in a new study
Genetic changes may set off a chain reaction that causes the spine’s natural shock absorbers to harden and deteriorate. Zebrafish with a faulty collagen-related gene developed mineral buildup and spinal fusion similar to human disc disease. Researchers were able to reduce the damage using an existing osteoporosis drug and by targeting fat metabolism. The discovery points to several exciting possibilities for future back pain treatments.
Scientists tracked 12 people in Antarctica for 10 months—what happened could shape future Mars missions
A ten-month Antarctic experiment found that astronauts may struggle not only with loneliness but also with spending too much time around the same people. Frequent contact was linked to greater tension and mistrust, while the crew increasingly divided into cultural and language-based groups.
Scientists find unexpected life on Ötzi the Iceman’s 5,300-year-old body
More than 5,000 years after his death, Ötzi the Iceman is still hosting a remarkable mix of ancient and modern microorganisms. Researchers separated microbes that lived in his body during his lifetime from those that arrived after his death, uncovering traces of his original gut bacteria and cold-loving yeasts that may have survived alongside him in the glacier for millennia.
Earth’s molten core suddenly reversed direction — and scientists don’t know why
Earth’s molten iron core unexpectedly reversed direction beneath the Pacific, revealing a dramatic change in the hidden engine that creates our planet’s magnetic field. Satellite data suggest the surge is already weakening, raising the possibility that the deep-Earth upheaval is part of a mysterious natural cycle.
Wearable ultrasound patch boosts REM sleep without drugs or surgery
A new wearable patch may help people reach REM sleep faster and remain there longer without medication or surgery. In a study of 28 participants, the device shortened the time to REM by 43 minutes and extended it by about 16 minutes. Researchers also observed signs of improved stress regulation and changes in brain circuits tied to emotion.
Scientists discover a hidden brain shift that begins around age 50
Beginning around age 50, the brain’s memory center appears to lose many of its longtime immune cells and replace them with more inflammatory ones. This surprising shift may help explain how normal aging sets the stage for Alzheimer’s disease and dementia.
New autism therapy shows surprising benefits even in adult mice
Blocking the glycine transporter SLC6A20 restored important brain signaling and improved social, communication, and repetitive behaviors in autism-related mouse models. The treatment also worked in human brain organoids and showed lasting effects in adult mice, suggesting the brain may remain more treatable later in life than previously thought.
The key to colonizing Mars may be hidden inside asteroids
Metal-rich asteroids could one day become hardware stores for Mars, supplying the materials needed to build and repair a growing colony. A new analysis shows that carefully selected asteroids may be reachable with current spacecraft technology. Some could even provide the ingredients for making rocket fuel in space, dramatically reducing the burden of hauling supplies from Earth.
Scientists rediscover lost Megalodon fossils—and reveal a 79-foot giant
Several enormous Megalodon vertebrae thought to have been destroyed in 1989 were found sitting unnoticed on a museum shelf. Their analysis strengthens evidence that the giant shark could exceed 24 meters (79 feet) in length and live for nearly a century. Researchers also estimate that its newborns may have measured an astonishing 3.6 meters (12 feet).
A star’s violent death exposed a hidden supermassive black hole
A supermassive black hole has been found lurking about 30,000 light-years from the center of its galaxy—the first dormant black hole detected so far from a galactic core. It revealed itself only after shredding a passing star and producing a brief, brilliant flare. Astronomers think it may be the remnant of a devoured galaxy or a black hole flung outward during a chaotic cosmic encounter.
Forget the sperm race: Fertilization may depend on teamwork
Millions of sperm do not always compete alone—some species send them into action as coordinated teams. A sweeping evolutionary study found that this cooperation is widespread among arthropods and has repeatedly emerged and vanished over hundreds of millions of years. The discovery challenges the classic “fastest sperm wins” story and could influence future fertility research and pest-control strategies.
A colossal magma system has been hiding beneath Tuscany
A massive magma reservoir has been detected deep beneath Tuscany, despite showing no obvious signs at the surface. Scientists mapped the roughly 6,000-cubic-kilometer body using natural ground vibrations recorded by dozens of seismic sensors. It poses no immediate danger, but the discovery reveals how enormous volcanic systems can remain hidden and could transform the search for geothermal energy and critical minerals.
