Salk Institute scientists discovered that bile acids in the liver can weaken immune cell function, making immunotherapy less effective against liver cancer. They pinpointed specific bile acids that suppress T cells and found that supplementing with UDCA reversed the effect, controlling tumor growth in mice. Since UDCA is already used for liver disease, it could quickly translate into clinical trials. Read more ›

Researchers have discovered chemical fingerprints of Earth's earliest incarnation, preserved in ancient mantle rocks. A unique imbalance in potassium isotopes points to remnants of “proto Earth” material that survived the planet’s violent formation. The study suggests the original building blocks of Earth remain hidden beneath its surface, offering a direct glimpse into our planet’s ancient origins. Read more ›

Researchers discovered how to stabilize a high-performance sodium compound, giving sodium-based solid-state batteries the power and stability they’ve long lacked. The new material conducts ions far more efficiently and supports thicker, energy-dense cathodes. Because it relies on a proven technique, it’s also easier to scale up for real-world use. This could bring safer, cheaper, greener batteries much closer to reality. Read more ›

Scientists from NASA and Chalmers University have discovered that incompatible substances can mix on Titan’s icy surface, breaking the “like dissolves like” rule of chemistry. Under ultra-cold conditions, hydrogen cyanide can form stable crystals with methane and ethane. This surprising reaction could help explain Titan’s mysterious landscapes and offer clues to how life’s building blocks formed. Read more ›

For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed delayed bursts of energy months after the initial destruction, hinting at mysterious, episodic black hole activity. This rare find reshapes understanding of where supermassive black holes reside and how they evolve. Read more ›

Long before humans built cities or wrote words, our ancestors may have faced a hidden threat that shaped who we became. Scientists studying ancient teeth found that early humans, great apes, and even Neanderthals were exposed to lead millions of years ago. This toxic metal can damage the brain, yet modern humans developed a tiny genetic change that protected our minds and allowed language and intelligence to flourish. Read more ›

Ryugu’s samples reveal that water activity on asteroids lasted far longer than scientists thought, possibly reshaping theories of how Earth gained its oceans. A billion-year-old impact may have melted ancient ice, keeping asteroids wet and influential far into solar system history. Read more ›

Researchers discovered a new field of ancient tektites in South Australia, revealing a long-forgotten asteroid impact. These 11-million-year-old glass fragments differ chemically and geographically from other known tektites. Although the crater remains missing, the find exposes a massive event once thought unrecorded, offering clues to Earth’s tumultuous past and planetary defense. Read more ›

Scientists discovered true teeth growing on the head of the spotted ratfish, a distant shark relative. The toothed structure, called a tenaculum, helps males hold onto females during mating. Genetic evidence shows these head teeth share the same origins as oral teeth, overturning assumptions that teeth only evolve in jaws. This discovery reshapes the story of dental evolution across vertebrates. Read more ›

New research reveals that Earth’s continents owe their stability to searing heat deep in the planet’s crust. At more than 900°C, radioactive elements shifted upward, cooling and strengthening the landmasses that support life. This ancient heat engine also distributed valuable minerals, giving scientists new clues for exploration and for spotting potentially habitable planets. Read more ›

Auburn scientists have designed new materials that manipulate free electrons to unlock groundbreaking applications. These “Surface Immobilized Electrides” could power future quantum computers or transform chemical manufacturing. Stable, tunable, and scalable, they represent a leap beyond traditional electrides. The work bridges theory and potential real-world use. Read more ›

Johns Hopkins scientists uncovered microscopic “nanotube” channels that neurons use to transfer toxic molecules. While this process clears waste, it can also spread harmful proteins like amyloid-beta. Alzheimer’s-model mice showed more nanotubes early on, hinting at a link to disease development. Researchers hope to one day control nanotube formation as a potential therapy. Read more ›

CO₂ ice blocks on Mars may dig gullies as they slide and sublimate in the thin atmosphere. In lab experiments, scientists recreated these eerie, worm-like movements under Martian conditions. The findings help explain unusual dune formations and deepen our understanding of how alien landscapes evolve. Read more ›

Scientists have found a way to transform hard-to-treat tumors into targets for the immune system. Using two protein stimulators, they activated strong T-cell and B-cell responses and built immune structures inside tumors that improved survival and prevented recurrence. This approach could make existing immunotherapies and chemotherapies more effective and long-lasting. Read more ›

A parasitic worm uses static electricity to launch itself onto flying insects, a mechanism uncovered by physicists and biologists at Emory and Berkeley. By generating opposite charges, the worm and insect attract, allowing the leap to succeed far more often. High-speed cameras and mathematical modeling confirmed this “electrostatic ecology” in action. Read more ›

Scientists discovered that lean pork builds muscle more effectively post-workout than high-fat pork, even with identical protein levels. Using advanced tracking techniques, they found that fat content blunted the body’s muscle-building response. The results contradict previous findings about fattier foods enhancing synthesis, suggesting that food form and processing matter. Read more ›

Korean researchers found that low-dose radiation therapy eased knee pain and improved movement in people with mild to moderate osteoarthritis. The treatment, far weaker than cancer radiation, showed real benefits beyond placebo. With no side effects and strong trial results, the approach could provide a middle ground between painkillers and joint surgery. Read more ›

Scientists discovered that specific nutrients in nematodes' diets activate stress defenses that keep their cells healthier over time. These RNAs prevent toxic protein buildup, promoting longevity and vitality. The worms fed with balanced diets lived more active, healthier lives. The findings hint that mild dietary stress could support better aging in humans as well. Read more ›

Scientists at TU Wien have uncovered that quantum correlations can stabilize time crystals—structures that oscillate in time without an external driver. Contrary to previous assumptions, quantum fluctuations enhance rather than hinder their formation. Using a laser-trapped lattice, the team demonstrated self-organizing rhythmic behavior arising purely from particle interactions. The finding could revolutionize quantum technology design.

Scientists at the University of Hawaiʻi have discovered why it rains on the Sun. Solar rain, made of cooling plasma, forms rapidly during solar flares, a mystery now solved by modeling time-varying elements like iron. The finding upends long-held assumptions about the Sun’s atmosphere and could improve predictions of space weather events. It’s a breakthrough that forces a rewrite of how we understand the Sun’s outer layers. Read more ›
