Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a problem that’s limited imaging and display technologies for years. By harnessing the power of radiation directionality and engineering bilayer metagratings with unique symmetry properties, they’ve decoupled these two variables for the first time. Their precise nanofabrication techniques allow for ultra-flat, highly aligned structures that selectively reflect light only at specific angl Read more ›

A massive spike in young children accidentally ingesting nicotine pouches has alarmed poison control researchers, with a 763% rise reported between 2020 and 2023. Unlike other nicotine products, these pouches have quickly become the most dangerous form ingested, often leading to hospital visits. Experts say appealing packaging and flavors are part of the problem and they're pushing for tougher safety measures, including childproof storage and flavor bans. Read more ›

Imagine a star powered not by nuclear fusion, but by one of the universe’s greatest mysteries—dark matter. Scientists have proposed the existence of “dark dwarfs,” strange glowing objects potentially lurking at the center of our galaxy. These stars might form when brown dwarfs absorb enough dark matter to prevent cooling, transforming into long-lasting beacons of invisible energy. A specific form of lithium could give them away, and if detected, these... Read more ›

A 2.35-billion-year-old Moon rock that fell to Earth in Africa is rewriting what we know about lunar volcanism. This rare meteorite, studied by UK scientists and unveiled at a major geochemistry conference, reveals that the Moon was volcanically active far longer than previously thought. With a unique chemical makeup and an age that bridges a billion-year gap in Moon rock samples, it suggests the Moon had internal heat sources that... Read more ›

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have likely been stripped of their dark matter by the Milky Way’s gravity and hidden from view. If spotted by next-gen telescopes like the Rubin Observatory’s LSST, they could solidify our understanding of the Universe’s structure and deliver a stunning validation of... Read more ›

Movement helps your mood, but it's not one-size-fits-all. Exercising for fun, with friends, or in enjoyable settings brings greater mental health benefits than simply moving for chores or obligations. Researchers emphasize that context — who you're with, why you're exercising, and even the weather — can make or break the mood-boosting effects. Read more ›

Postmenopausal women struggling with weight loss may find a powerful solution by combining the diabetes drug tirzepatide with menopause hormone therapy. A Mayo Clinic study revealed that this dual treatment led to significantly greater weight loss than tirzepatide alone. Women using both treatments lost 17% of their body weight on average, compared to 14% in those not using hormone therapy—and nearly half achieved dramatic 20%+ weight loss. Read more ›

Aging men aren't just battling time—they're up against rising blood sugar. New research reveals that subtle increases in metabolic markers like glucose have more influence on declining sexual health than age or testosterone levels alone. The findings, based on a 6-year study of otherwise healthy men, show that even below-diabetes-level sugar changes can impair sperm mobility and erectile function. But there’s good news: lifestyle choices and medical support could help... Read more ›

In a striking new study, the anti-obesity drug tirzepatide, known as Mounjaro and Zepbound, not only triggered significant weight loss in obese mice but also slashed breast cancer tumor growth. The research, presented at ENDO 2025, links body fat reduction to better cancer outcomes, suggesting that these next-generation weight-loss drugs might offer unexpected benefits beyond metabolic health. With traditional dieting often falling short, this dual-action approach could reshape how doctors... Read more ›

For centuries, we’ve imagined Neanderthals as distant cousins — a separate species that vanished long ago. But thanks to AI-powered genetic research, scientists have revealed a far more entangled history. Modern humans and Neanderthals didn’t just cross paths; they repeatedly interbred, shared genes, and even merged populations over nearly 250,000 years. These revelations suggest that Neanderthals never truly disappeared — they were absorbed. Their legacy lives on in our DNA,... Read more ›

A cat named Pepper has once again helped scientists discover a new virus—this time a mysterious orthoreovirus found in a shrew. Researchers from the University of Florida, including virologist John Lednicky, identified this strain during unrelated testing and published its genome. Although once thought to be harmless, these viruses are increasingly linked to serious diseases in humans and animals. With previous discoveries also pointing to a pattern of viral emergence...

A surprising new study has uncovered over 200 misfolded proteins in the brains of aging rats with cognitive decline, beyond the infamous amyloid and tau plaques long blamed for Alzheimer’s. These shape-shifting proteins don’t clump into visible plaques, making them harder to detect but potentially just as harmful. Scientists believe these “stealth” molecules could evade the brain’s cleanup systems and quietly impair memory and brain function. The discovery opens a... Read more ›

A major breakthrough in Maya archaeology has emerged from Caracol, Belize, where the University of Houston team uncovered the tomb of Te K'ab Chaak—Caracol’s first known ruler. Buried with elaborate jade, ceramics, and symbolic artifacts, the tomb offers unprecedented insight into early Maya royalty and their ties to the powerful Mexican city of Teotihuacan. Read more ›

Adopting a physically active lifestyle at any stage of adulthood significantly lowers your risk of dying from any cause, especially from cardiovascular disease. A sweeping analysis of 85 studies confirms that those who stay active consistently reduce their mortality risk by 30–40%, while even those who become active later in life enjoy a 20–25% reduction.

A university student on a fossil-hunting field trip in Dorset made a stunning discovery: a 145-million-year-old jawbone belonging to a previously unknown mammal species with razor-like teeth. With the help of CT scanning, 3D printing, and expert analysis, the fossil was revealed to be Novaculadon mirabilis, a multituberculate that lived alongside dinosaurs. This is the first find of its kind from the area in over a century, and the fossil’s... Read more ›

Even in a warming climate, brutal cold snaps still hammer parts of the U.S., and a new study uncovers why. High above the Arctic, two distinct polar vortex patterns — both distorted and displaced — play a major role in steering icy air toward different regions. One sends it plunging into the Northwest, while the other aims it at the Central and Eastern U.S. Since 2015, the westward version has... Read more ›

Scientists at ETH Zurich have broken new ground by generating over 400 types of nerve cells from stem cells in the lab, far surpassing previous efforts that produced only a few dozen. By systematically experimenting with combinations of morphogens and gene regulators, the researchers replicated the vast diversity of neurons found in the human brain. This breakthrough holds major promise for studying neurological diseases like Alzheimer’s and Parkinson’s, creating more... Read more ›

A team of researchers has discovered that a protein called cypin plays a powerful role in helping brain cells connect and communicate, which is crucial for learning and memory. By uncovering how cypin tags certain proteins at synapses and interacts with the brain’s protein recycling system, scientists are opening doors to possible treatments for Alzheimer's, Parkinson's, and traumatic brain injuries. This breakthrough could be the first step toward boosting brain... Read more ›

A team at Scripps Research has created a microchip that can rapidly reveal how a person's antibodies respond to viruses using only a drop of blood. This game-changing technology, called mEM, condenses a week’s worth of lab work into 90 minutes, offering a powerful tool for tracking immune responses and fast-tracking vaccine development. Unlike earlier methods, it needs far less blood and delivers more detailed insights, even revealing previously undetected... Read more ›
