95% success rate: This new trick lures termites straight to their death6:34 Scientists at UC Riverside have found a clever new way to outsmart termites—by turning their own instincts against them. Using a natural pine scent called pinene, which smells like food to termites, researchers can lure the pests straight toward a targeted dose of insecticide hidden in wood. The result is dramatically higher kill rates—jumping from about 70% to over 95%—without the need for wides… Hundreds of millions at risk as river deltas sink faster than rising seas6:34 Many of the world’s largest river deltas—home to hundreds of millions of people—are sinking faster than rising seas, according to a sweeping global study. Using high-resolution satellite radar maps, researchers found that human activities like groundwater pumping, reduced sediment flow, and rapid urban growth are driving widespread land subsidence across 40 major deltas. AI swarms could hijack democracy without anyone noticing6:34 AI-powered personas are becoming so realistic that they can infiltrate online communities and subtly steer public opinion. Unlike traditional bots, they adapt, coordinate, and refine their messaging at a massive scale, creating a false sense of consensus. Early warning signs—like deepfakes and fake news networks—have already appeared in global elections. Researchers warn that the next election co… This missing vitamin could stop cancer cells in their tracks6:34 Cancer cells are known for their “glutamine addiction,” but many can escape this weakness by switching to alternative fuels. Researchers found that vitamin B7 acts like a metabolic “license,” enabling this escape route through a key enzyme. Without biotin, cancer cells lose that flexibility and stop growing. Mutations in a cancer-linked gene can make this vulnerability even stronger, offering a p… This simple 3-amino acid trick boosts mRNA therapy 20-fold6:34 A trio of common amino acids may hold the key to unlocking far more powerful gene therapies. Researchers found that adding them to lipid nanoparticles can boost mRNA delivery up to 20-fold and push CRISPR editing efficiency close to 90%. The trick isn’t changing the drug—but helping cells take it in more easily. In early tests, the approach dramatically improved survival and treatment outcomes, p… These California bees are beating a killer that’s wiping out colonies6:34 A unique hybrid honeybee thriving in Southern California may hold a powerful clue to saving struggling bee populations. While U.S. beekeepers are losing massive numbers of colonies—largely due to destructive Varroa mites—a locally adapted mix of feral and diverse bee lineages is showing remarkable resilience. These bees aren’t immune, but they carry far fewer mites and are far less likely to requ… This common plant could clean microplastics from your drinking water6:34 Scientists have discovered that moringa seeds can help pull microplastics out of water, rivaling standard chemical treatments. The plant-based extract causes plastic particles to clump together, making them easier to filter away. In some conditions, it even outperformed conventional chemicals. This low-cost, natural solution could be a game-changer for cleaner drinking water, especially in smalle… Scientists stunned as bacteria rewire DNA machinery to shape cells6:34 Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once used to separate DNA has been repurposed into something entirely different: a structure that shapes the cell itself. After 200 years scientists finally crack the “dolomite problem”20.dubna After two centuries of failed attempts, scientists have finally grown dolomite in the lab, cracking a long-standing geological puzzle. They discovered that the mineral’s growth stalls because of tiny defects—but in nature, those flaws get washed away over time. By mimicking this process with precise simulations and electron beam pulses, the team achieved record-breaking crystal growth. The findin… A new force of nature is reshaping the planet, study finds19.dubna Human societies didn’t just adapt to the planet—they learned to reshape it. From early fire use to today’s global supply chains, our cultural and social innovations have unlocked extraordinary power to transform Earth and improve human life. But that progress has come with serious costs, including climate change, pollution, and mass extinction. Instead of framing this era—the Anthropocene—as pure… Scientists develop dirt-powered fuel cell that could replace batteries19.dubna Scientists have developed a fuel cell that uses microbes in soil to produce electricity. The device can power underground sensors for tasks like monitoring moisture or detecting touch, without needing batteries or solar panels. It works in both dry and wet conditions and even lasts longer than similar technologies. This could pave the way for sustainable, low-maintenance sensors in farming and en… Scientists just found a way to control electrons without magnets19.dubna A surprising breakthrough in physics could reshape the future of computing by tapping into a strange, previously untapped property of matter. Scientists have shown that tiny atomic vibrations—called chiral phonons—can directly transfer motion to electrons, allowing them to carry information without magnets, batteries, or even electricity. This opens the door to a new field known as orbitronics, w… Why two-sun planets keep disappearing scientists blame Einstein19.dubna Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars—like Star Wars’ Tatooine—are surprisingly rare, even though they should be common. New research suggests the culprit is none other than Einstein’s theory of general relativity. Think AI "knows" what it’s doing? Scientists say think again19.dubna Calling AI things like “smart” or saying it “knows” something might sound harmless, but it can quietly mislead people about what AI actually does. A new study shows that news writers are more careful than expected, rarely using strongly human-like language. When they do, it often falls on a spectrum—sometimes describing simple requirements, other times hinting at human traits. Scientists say this type of olive oil could boost brain power19.dubna Extra virgin olive oil might help protect your brain by working through your gut. A two-year study found that people who consumed it had better cognitive performance and more diverse gut bacteria than those using refined olive oil. Researchers even identified specific microbes linked to these benefits. The findings suggest that choosing high-quality olive oil could be a simple way to support brai… |
