DNA treatment cuts bad cholesterol by nearly 50% without statins
Researchers have designed a new DNA-based treatment that targets PCSK9, a protein closely tied to high LDL cholesterol and atherosclerosis. Their most effective molecule reduced …
The Moon may have formed intact just hours after a giant collision
Scientists have discovered that the Moon-forming collision may have depended heavily on how hot and physically strong early Earth and Theia were. New simulations found …
Scientists finally see DNA “zip” itself together for the first time
Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge …
One sugary drink a day linked to more than double the risk …
People who drank at least one sugar-sweetened beverage a day had roughly 2.45 times the risk of gastric cancer compared with those who rarely consumed …
400,000-year-old teeth reveal a hidden link in human evolution
More than 400,000-year-old Homo erectus teeth from China may reveal a surprising link between this ancient human species, Denisovans, and some modern people. Scientists found …
Raindrops can damage paint with microscopic “lightning”
Scientists discovered that charged water droplets can damage protective coatings by releasing tiny electrical discharges when they hit a surface. The hidden effect could help …
Scientists find a bone-building switch that could fight osteoporosis
An experimental compound called AP503 significantly strengthened bones in mice by activating GPR133, a receptor that boosts bone formation while slowing bone loss. Because the …
Ozempic and Wegovy linked to nearly 40% fewer asthma attacks
Semaglutide, the drug found in Ozempic and Wegovy, was linked to nearly 40% fewer asthma attacks in a large real-world study. It was also associated …
Have we found alien life? Hundreds of scientists weigh in
Two major alien-life announcements in 2025 generated enormous excitement, but most astrobiologists remained unconvinced. Only 6.6% of surveyed experts thought possible biological molecules on K2-18b …
Interstellar comet 3I/ATLAS is bursting with methanol
Interstellar comet 3I/ATLAS contains exceptionally high levels of methanol, suggesting it formed under conditions very different from those that shaped most comets in our solar …
Devil’s Arrows: Ancient builders hauled 55,000-pound stones 11 miles for Britain’s tallest …
Britain’s towering Devil’s Arrows were built from 25-tonne stones hauled at least 18 kilometers from Brimham Rocks around 4,000 years ago. The discovery reveals an …
“Parachute science” is failing the tropics, home to more than 80% of …
Insects quietly hold much of the natural world together, yet conservation efforts are overlooking the tropical regions where more than 80 percent of insect species …
Chinese scientists find a hidden atomic structure that unlocks methane
Scientists found that a tiny atomic structure that forms on nickel oxide during methane conversion is more effective than the metallic nickel long believed to …
Geologists reveal the Americas collided millions of years earlier than thought
Volcanic rocks in Colombia are rewriting the timeline of the collision between Central and South America. Their magnetic signatures show that major tectonic deformation had …
Dark energy debunked? Cosmic acceleration may be an illusion
A new analysis of more than 1,700 supernovae is questioning whether the universe is really accelerating at all. After accounting for the ages of the …
Astronomers detect ancient hydrogen signal that could help map the Universe
Astronomers have detected an exceptionally faint hydrogen radio signal from billions of light-years away using South Africa’s MeerKAT telescope. Instead of finding galaxies one at …
Caffeine may flip an ancient cellular switch linked to slower aging
Scientists found that caffeine activates an ancient cellular energy system involved in stress resistance, DNA repair, and growth. The discovery could help explain caffeine’s links …
Scientists discover a powerful new antivenom hidden in rattlesnake blood
Researchers discovered that combinations of toxin-blocking proteins naturally found in rattlesnake blood can powerfully neutralize venom from several dangerous snake species. In lab tests, the …
Your personality may be more genetic than scientists realized
More than 1,200 genetic variants have been linked to the Big Five personality traits, and many of the same variants are also associated with health, …
Ozempic and Wegovy may have an unexpected mental health benefit
Semaglutide, the drug behind Ozempic and Wegovy, may have benefits that extend well beyond weight loss and diabetes. In a large Swedish study of nearly …
Giant new dinosaur discovered beneath construction site in Brazil
Scientists have identified a giant new dinosaur from Brazil that reached about 20 meters long and lived 120 million years ago. Its surprising evolutionary ties …
Scientists observe Einstein’s gravity in the quantum world for the first time
Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers …
The American “cheetah” wasn’t a cheetah at all
The extinct “American cheetah” was not really a cheetah at all, but a puma relative with an unexpectedly flexible lifestyle. Fossils from the Yukon suggest …
