Fast walking, even just 15 minutes a day, can dramatically reduce the risk of death, especially from heart disease, according to a large study involving nearly 80,000 low-income and predominantly Black Americans in the South. The findings not only affirm the well-known health benefits of walking but also highlight how pace matters and how fast walking offers a powerful, accessible tool for improving health across underserved communities.

A mysterious gut hormone may be behind many cases of chronic diarrhea, especially in people with undiagnosed bile acid malabsorption, a condition often mistaken for irritable bowel syndrome. Researchers from the University of Cambridge identified that the hormone INSL5 spikes when bile acid reaches the colon, triggering intense diarrhea. Their discovery not only sheds light on the biological cause of symptoms but opens the door to a diagnostic blood test... Read more ›

In the quest to understand how and why early humans started walking on two legs, scientists are now looking to chimpanzees living in dry, open savannah-like environments for clues. A new study reveals that these chimpanzees, despite the open terrain, still frequently climb trees to gather fruit and other foods found high in the canopy. Their behavior suggests that bipedalism may not have evolved purely as a response to ground-based... Read more ›

Scientists have cracked open a mysterious layer inside batteries, using cutting-edge 3D atomic force microscopy to capture the dynamic molecular structures at their solid-liquid interfaces. These once-invisible electrical double layers (EDLs) twist, break, and reform in response to surface irregularities phenomena never seen before in real-world battery systems. The findings don t just refine our understanding of how batteries work at the microscopic level they could fundamentally change how we... Read more ›

Scientists at Columbia Engineering have developed an injectable hydrogel made from yogurt-derived extracellular vesicles (EVs) that could revolutionize regenerative medicine. These EVs serve both as healing agents and as structural components, eliminating the need for added chemicals. The innovation leverages everyday dairy products like yogurt to create a biocompatible material that mimics natural tissue and enhances healing. Read more ›

For the first time ever, scientists have watched electrons perform a bizarre quantum feat: tunneling through atomic barriers by not just slipping through, but doubling back and slamming into the nucleus mid-tunnel. This surprising finding, led by POSTECH and Max Planck physicists, redefines our understanding of quantum tunneling—a process that powers everything from the sun to your smartphone. Read more ›

Neutrinos, ghostly particles barely interacting with matter, may secretly be reshaping the fates of massive stars. New research suggests that as stars collapse, they form natural "neutrino colliders," allowing scientists to probe these elusive particles in ways never possible on Earth. If neutrinos do interact through yet-undiscovered forces, they could cause stars to collapse into black holes instead of neutron stars, reshaping how we understand cosmic evolution. Read more ›

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto University have linked this advantage to cryptographic puzzles, showing that the same conditions that allow secure quantum cryptography also define when quantum computing outpaces classical methods.

Walking just a bit faster could be the key to aging well. Researchers found that older adults who upped their walking pace by just 14 steps per minute significantly improved their physical abilities—even those who were already frail. A new, user-friendly smartphone app helps measure walking cadence more accurately than typical devices, making this science-backed health strategy easy to adopt. By shifting from a casual stroll to a brisker walk,... Read more ›

Eggs are finally being vindicated after decades of cholesterol-related blame. New research from the University of South Australia reveals that eggs, despite their cholesterol content, aren't the dietary villains they've long been made out to be. Instead, it's the saturated fats found in foods like bacon and sausage that actually elevate harmful LDL cholesterol levels. In a world-first study, researchers showed that eating two eggs a day, as part of... Read more ›

Over-the-counter (OTC) products like St John’s Wort and omega-3s have long been touted for helping with depression, but new research reveals that 64 different OTC products have been tested in clinical trials, with varying levels of evidence. Some well-known options like St John’s Wort, saffron, and probiotics showed encouraging results, sometimes comparable to antidepressants. Others like folic acid, lavender, and lemon balm show emerging promise. Although few safety concerns were... Read more ›

Many people with dementia endure long delays—often over 3 years—before receiving a diagnosis, with even longer waits for younger patients. A global review of over 30,000 cases reveals that age, dementia type, and systemic healthcare issues like specialist access and cultural barriers contribute to these delays. Researchers call for coordinated strategies to raise public awareness, reduce stigma, and train clinicians to recognize early symptoms and streamline referrals. Read more ›

Penn State researchers have uncovered a surprising twist in a foundational chemical reaction known as oxidative addition. Typically believed to involve transition metals donating electrons to organic compounds, the team discovered an alternate path—one in which electrons instead move from the organic molecule to the metal. This reversal, demonstrated using platinum and palladium exposed to hydrogen gas, could mean chemists have misunderstood a fundamental step for decades. The discovery opens... Read more ›

Scientists at OIST have defied a foundational rule in chemistry by creating a stable 20-electron version of ferrocene—an organometallic molecule once thought to be limited to 18 valence electrons. This discovery not only challenges conventional wisdom but unlocks new chemical behaviors and redox states, potentially transforming how catalysts and materials are designed. Read more ›

Deep in Serbia's Jadar Valley, scientists discovered a mineral with an uncanny resemblance to Superman's Kryptonite both in composition and name. Dubbed jadarite, this dull white crystal lacks the glowing green menace of its comic book counterpart but packs a punch in the real world. Rich in lithium and boron, jadarite could help supercharge the global transition to green energy. Read more ›

Air pollution isn't just bad for your lungs—it may be eroding your brain. In a sweeping review covering nearly 30 million people, researchers found that common pollutants like PM2.5, nitrogen dioxide, and soot are all linked to a significantly higher risk of dementia. The most dangerous? PM2.5—tiny particles from traffic and industry that can lodge deep in your lungs and reach your brain. Read more ›

Walking 7000 steps a day may be just as powerful as hitting the much-hyped 10,000-step goal when it comes to reducing the risk of early death and disease. A sweeping global review of 57 studies shows that 7000 steps per day slashes the risk of dying early by nearly half—and brings major benefits across heart health, dementia, depression, and more. The bonus? Even walking from 2000 to 4000 steps per... Read more ›

In 2023, the world’s oceans experienced the most intense and widespread marine heatwaves ever recorded, with some events persisting for over 500 days and covering nearly the entire globe. These searing ocean temperatures are causing mass coral bleaching and threatening fisheries, while also signaling deeper, system-wide climate changes. Read more ›

A pioneering team at the University of Maryland has captured the first-ever images of atomic thermal vibrations, unlocking an unseen world of motion within two-dimensional materials. Their innovative electron ptychography technique revealed elusive “moiré phasons,” a long-theorized phenomenon that governs heat, electronic behavior, and structural order at the atomic level. This discovery not only confirms decades-old theories but also provides a new lens for building the future of quantum computing,... Read more ›
