Scientists find natural compounds that hit COVID-19 from every angle4:01 A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts—blocking the virus from entering cells, disrupting its replication, and even dampening harmful inflammation. Unlike many antivirals that target just one part of the vir… Eating eggs could cut Alzheimer’s risk by 27%0:50 Eating eggs might do more than just start your day—it could help protect your brain. Researchers found that people 65 and older who eat eggs regularly have a significantly lower risk of developing Alzheimer’s disease, with daily or near-daily consumption linked to up to a 27% reduction. Even modest egg intake showed benefits, suggesting that small dietary changes could make a meaningful differenc… Webb space telescope finds a giant galaxy that doesn’t spin0:50 Astronomers using the James Webb Space Telescope have spotted something that shouldn’t exist—at least not so early in the universe. A massive galaxy, formed less than 2 billion years after the Big Bang, appears to have no rotation at all, a trait usually seen only in much older, evolved galaxies. This challenges current theories that young galaxies should still be spinning from their formation. This strange planet pair shouldn’t exist, but it does23:15 A bizarre planetary pairing 190 light-years away is challenging everything astronomers thought they knew about how worlds form. A “lonely” hot Jupiter — typically found without nearby companions — is sharing its system with a smaller mini-Neptune tucked even closer to the star, a setup once thought nearly impossible. New “Trojan horse” obesity drug supercharges weight loss in early tests13:08 Researchers have created a next-generation obesity drug that works like a “Trojan horse,” using GLP-1/GIP signals to slip a powerful metabolic enhancer directly into target cells. In mice, it outperformed existing treatments—curbing appetite, increasing weight loss, and improving blood sugar levels. Because the extra drug acts only where it’s needed, it can be used at much lower doses, potentiall… Scientists discover why Ozempic works better for some people13:08 Some people taking Ozempic-like diabetes drugs may be getting dramatically better results for a surprising reason: why they overeat in the first place. A year-long study in Japan found that people who tend to eat because tempting food looks or smells irresistible were much more likely to lose weight and improve blood sugar levels on GLP-1 medications. But people who eat mainly in response to stre… Scientists find a way to stop dangerous belly fat as we age12:03 Aging doesn’t just add fat—it redistributes it in risky ways, pushing more into the abdomen where it can harm health. Scientists found that testosterone plays a key role in this shift. In older women recovering from hip fractures, a testosterone gel combined with exercise helped prevent the usual rise in dangerous visceral fat. The result could point to a powerful new strategy for improving recov… Scientists accidentally discover DNA that breaks the rules of life9:55 A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers stumbled upon a bizarre genetic code in a microscopic pond organism. Instead of following the near-universal “rules” of life, this newly identified protist rewrites how genes signal their end. This unexpected discovery challenges long-held assumptions about how genetic tran… People once risked everything just to keep their hats on9:55 Centuries ago in England, hats weren’t just accessories—they were statements of power and rebellion. Refusing to remove a hat could challenge authority, even in courtrooms and before kings. People valued their hats so deeply that robbery victims sometimes begged to keep them over money. In a world where going bareheaded signaled poverty or madness, hats shaped identity, respect, and even family d… Your DNA may predict your future success more than your upbringing9:55 A new twin study suggests your genes may play a bigger role in your future success than your upbringing. Researchers found that IQ, which is largely genetically influenced, strongly predicts education, career, and income. Even twins raised in the same household diverged based on genetic differences. The findings hint that life outcomes may be more hardwired than many people expect. This town found clean energy deep inside old coal mines5:09 Cumberland, B.C. is reimagining its coal mining past as a clean energy opportunity. Water trapped in abandoned mine tunnels could be used in a geothermal system to heat and cool buildings efficiently and with minimal emissions. The project could lower energy costs, support new development, and attract businesses. It’s a striking example of turning industrial leftovers into a sustainable community… Scientists finally solve 40-year-old physics puzzle about how things grow5:09 In a major breakthrough, scientists have experimentally confirmed a universal growth law in two dimensions using a quantum system of fleeting light–matter particles. The finding strengthens the idea that wildly different processes—from crystals to living systems—may all follow the same hidden rules. Scientists reverse diabetes in mice with lab-grown insulin cells5:09 Scientists in Sweden have taken a major step toward a potential cure for type 1 diabetes by developing a more reliable way to create insulin-producing cells from human stem cells. These lab-grown cells not only respond strongly to glucose but were also able to restore blood sugar control when transplanted into diabetic mice. NASA captures wild swirling clouds and rare arctic storm over Alaska5:09 Southern Alaska’s winter finale delivered a spectacular atmospheric display, captured by a NASA satellite. Cold Arctic air flowing over warmer ocean waters created long bands of clouds, swirling vortex patterns, and even a compact polar storm with powerful winds. As the air traveled offshore, it evolved into increasingly complex cloud formations. The result was a dramatic, ever-changing sky that … NASA just tested a powerful new thruster that could send humans to Mars5:09 A powerful new electromagnetic thruster has taken a major step forward after a successful high-energy test at NASA’s Jet Propulsion Laboratory. Fueled by lithium vapor and driven by intense magnetic forces, the experimental engine reached record-breaking power levels—far beyond anything currently used in space. Glowing hotter than molten lava and firing inside a specialized vacuum chamber, the th… |
