In just one afternoon, scientists used a nanoparticle “megalibrary” to find a catalyst that matches or exceeds iridium’s performance in hydrogen fuel production, at a fraction of the cost.

A Mediterranean-style diet was linked to lower dementia risk, especially in people with high-risk Alzheimer’s genes. The strongest benefits were seen in those with two APOE4 copies, showing diet may help offset genetic vulnerability. Researchers say food may influence key metabolic pathways that protect memory and cognitive function.

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This finding bridges the “RNA world” and “thioester world” theories and suggests how life’s earliest peptides may have formed.

Using cannabis to self-medicate comes with hidden dangers—new research shows these users face higher paranoia and consume more THC. Childhood trauma further amplifies the risks, especially emotional abuse, which strongly predicts paranoia.

James Webb has revealed that the Butterfly Nebula hides a complex mix of gemstone-like crystals, fiery dust, and unexpected carbon molecules. The discovery may rewrite how we understand the chemistry that seeds planets and life itself.

Whale sharks in Indonesia are suffering widespread injuries, with a majority scarred by human activity. Researchers found bagans and boats to be the biggest threats, especially as shark tourism grows. Protecting these gentle giants may be as simple as redesigning fishing gear and boat equipment.

In Taiwan’s forests, researchers discovered a clever hunting trick by the sheet web spider Psechrus clavis. Instead of immediately devouring captured fireflies, the spiders allow them to glow in the web, luring other insects, sometimes even more fireflies, into the trap. Experiments with LED lights confirmed this eerie strategy: webs lit with firefly-like signals attracted up to ten times more prey.

While superconducting qubits are great at fast calculations, they struggle to store information for long periods. A team at Caltech has now developed a clever solution: converting quantum information into sound waves. By using a tiny device that acts like a miniature tuning fork, the researchers were able to extend quantum memory lifetimes up to 30 times longer than before. This breakthrough could pave the way toward practical, scalable quantum computers that can both compute and remember.

Scientists have discovered that waxworm caterpillars can break down polyethylene plastic, one of the most common and persistent pollutants on Earth. These “plastivores” metabolize plastic into body fat within days, offering a striking potential solution to the global waste crisis. But there’s a twist: on a plastic-only diet, the caterpillars weaken and die quickly.

Researchers propose that the U.S. could safely drop adult tetanus and diphtheria boosters, saving $1 billion annually, since childhood vaccinations provide decades of protection. Evidence from the U.K. shows that skipping boosters has not led to higher disease rates.

WISPIT 2b, a gas giant forming around a young Sun-like star, has been directly imaged for the first time inside a spectacular multi-ringed disk. Still glowing and actively accreting gas, the planet offers a unique opportunity to study planetary birth and evolution.

Deep beneath the Pacific Ocean, a bright yellow worm thrives where no other animals dare, in toxic hydrothermal vents saturated with arsenic and sulfide. By cleverly turning these poisons into a golden mineral once prized by Renaissance painters, the worm neutralizes the deadly threat and survives in one of Earth’s most hostile habitats. Scientists say this unusual “fighting poison with poison” strategy could change how we think about life’s resilience in extreme environments.

Ancient forests may have fueled a deep-sea oxygen boost nearly 390 million years ago, unlocking evolutionary opportunities for jawed fish and larger marine animals. New isotopic evidence shows that this permanent oxygenation marked a turning point in Earth’s history — a reminder of how fragile the ocean’s oxygen balance remains today.

Bumble bees aren’t random foragers – they’re master nutritionists. Over an eight-year field study in the Colorado Rockies, scientists uncovered that different bee species strategically balance their intake of protein, fats, and carbs by choosing pollen from specific flowers. Larger, long-tongued bees seek protein-rich pollen, while smaller, short-tongued species prefer carb- and fat-heavy sources. These dietary preferences shift with the seasons and colony life cycles, helping bees reduce competition, thrive together, and maintain strong colonies.

Researchers have developed a blueprint for weaving hopfions—complex, knot-like light structures—into repeating spacetime crystals. By exploiting two-color beams, they can generate ordered chains and lattices with tunable topology, potentially revolutionizing data storage, communications, and photonic processing.

Researchers in Germany have unveiled the Metafiber, a breakthrough device that allows ultra-precise, rapid, and compact control of light focus directly within an optical fiber. Unlike traditional systems that rely on bulky moving parts, the Metafiber uses a tiny 3D nanoprinted hologram on a dual-core fiber to steer light by adjusting power between its cores. This enables seamless, continuous focus shifts over microns with excellent beam quality.

Hydrogen fuel cells could power cars, devices, and homes with nothing but water as a byproduct—but platinum’s cost holds them back. Chinese researchers have now unveiled a breakthrough iron-based catalyst that could rival platinum while boosting efficiency and durability. With its clever “inner activation, outer protection” design, this new catalyst not only reduces harmful byproducts but also shatters performance records, potentially paving the way for cleaner, cheaper, and more practical hydrogen energy.

Even sharks’ famous tooth-regrowing ability may not save them from ocean acidification. Researchers found that future acidic waters cause shark teeth to corrode, crack, and weaken, threatening their effectiveness as hunting weapons and highlighting hidden dangers for ocean ecosystems.

Knee osteoarthritis is a major cause of pain and disability, but routine X-rays often do more harm than good. New research shows that being shown an X-ray can increase anxiety, make people fear exercise, and lead them to believe surgery is the only option, even when less invasive treatments could help. By focusing on clinical diagnosis instead, patients may avoid unnecessary scans, reduce health costs, and make better choices about their care.

Astronomers have discovered a giant Saturn-sized planet orbiting TOI-6894, the smallest star ever known to host such a world. The finding overturns long-held theories suggesting that tiny, low-mass stars lack the material needed to form or keep giant planets.
