A new discovery may explain why so many people abandon cholesterol-lowering statins because of muscle pain and weakness. Researchers found that certain statins can latch onto a key muscle protein and trigger a tiny but harmful calcium leak inside muscle cells. That leak may weaken muscles directly or activate processes that slowly break them down, offering a long-sought explanation for statin-related aches.

Scientists have identified a newly recognized threat lurking beneath the ocean’s surface: sudden episodes of underwater darkness that can last days or even months. Caused by storms, sediment runoff, algae blooms, and murky water, these “marine darkwaves” dramatically reduce light reaching the seafloor, putting kelp forests, seagrass, and other light-dependent life at risk.

Scientists are taking a closer look at monk fruit and discovering it’s more than just a sugar substitute. New research shows its peel and pulp contain a rich mix of antioxidants and bioactive compounds that may support health. Different varieties offer different chemical profiles, hinting at unique benefits. The work could shape how monk fruit is used in future foods and supplements.

A massive international brain study has revealed that memory decline with age isn’t driven by a single brain region or gene, but by widespread structural changes across the brain that build up over time. Analyzing thousands of MRI scans and memory tests from healthy adults, researchers found that memory loss accelerates as brain tissue shrinkage increases, especially later in life. While the hippocampus plays a key role, many other brain regions also contribute, forming a broad vulnerability rather than isolated damage.

Earth’s oceans reached their highest heat levels on record in 2025, absorbing vast amounts of excess energy from the atmosphere. This steady buildup has accelerated since the 1990s and is now driving stronger storms, heavier rainfall, and rising sea levels. While surface temperatures fluctuate year to year, the ocean’s long-term warming trend shows no sign of slowing.

A new study reveals that alpha brain waves help the brain decide what belongs to your body. Faster rhythms allow the brain to match sight and touch more precisely, strengthening the feeling that a body part is truly yours. Slower rhythms blur that timing, making it harder to separate self from surroundings. The findings could improve prosthetic design and immersive virtual experiences.

Some people get drunk without drinking because their gut bacteria produce alcohol from food. Researchers have now identified the microbes and biological pathways behind this rare condition, auto-brewery syndrome. Tests showed patients’ gut samples produced far more alcohol than those of healthy people. In one case, a fecal transplant led to long-lasting symptom relief.

Despite longstanding guidelines, many dementia patients are still prescribed brain-altering medications that can raise the risk of falls and confusion. A new study shows that while prescribing has decreased overall, people with cognitive impairment remain more likely to receive these drugs. In many cases, there was no documented medical justification. The results suggest that medication safety remains a serious concern in dementia care.

A damaging cotton virus thought to be a recent invader has actually been hiding in U.S. fields for nearly two decades. New research shows cotton leafroll dwarf virus was present as early as 2006, quietly spreading across major cotton-growing states long before it was officially identified. By reanalyzing old genetic data with modern tools, scientists uncovered a hidden history of the virus’s spread—including its first confirmed appearance in California and even traces in animal feed.

Researchers studying cyanobacteria from hot springs in Thailand have discovered a new natural UV-blocking compound with impressive antioxidant power. Unlike conventional sunscreens, it’s biocompatible and potentially safer for both people and the environment. The molecule is produced only under UV and salt stress and uses a unique biosynthetic pathway never seen before. This could help drive a new generation of eco-friendly sunscreens and skincare products.

A generative AI system can now analyze blood cells with greater accuracy and confidence than human experts, detecting subtle signs of diseases like leukemia. It not only spots rare abnormalities but also recognizes its own uncertainty, making it a powerful support tool for clinicians.

Childbirth depends not just on hormones, but on the uterus’s ability to sense physical force. Scientists found that pressure and stretch sensors in uterine muscles and surrounding nerves work together to trigger coordinated contractions. When these sensors are disrupted, contractions weaken and delivery slows. The discovery helps explain stalled labor—and could one day lead to better ways to manage childbirth.

Scientists have pulled back the curtain on one of the most extreme solar regions seen in decades, tracking it almost nonstop for three months as it unleashed powerful space weather. By combining views from two spacecraft—one near Earth and one orbiting the Sun—researchers followed a massive active region as it grew, twisted, and ultimately triggered the strongest geomagnetic storms since 2003.

At extreme pressures and temperatures, water becomes superionic — a solid that behaves partly like a liquid and conducts electricity. This unusual form is believed to shape the magnetic fields of Uranus and Neptune and may be the most common type of water in the solar system. New high-precision experiments show its atomic structure is far messier than expected, combining multiple crystal patterns instead of one clean arrangement. The finding reshapes models of icy planets both near and far.

Honey bees can normally keep their hives perfectly climate-controlled, but extreme heat can overwhelm their defenses. During a scorching Arizona summer, researchers found that high temperatures caused damaging temperature fluctuations inside hives, leading to population declines. Smaller colonies were hit hardest, experiencing the most severe swings. As global temperatures rise, heat waves could pose a growing threat to bees and the pollination they provide.

Scientists tracking Earth’s water from space discovered that El Niño and La Niña are synchronizing floods and droughts across continents. When these climate cycles intensify, far-apart regions can become unusually wet or dangerously dry at the same time. The study also found a global shift about a decade ago, with dry extremes becoming more common than wet ones. Together, the results show that water crises are part of a global pattern, not isolated events.

Scientists at Tufts have found a way to turn common glucose into a rare sugar that tastes almost exactly like table sugar—but with far fewer downsides. Using engineered bacteria as microscopic factories, the team can now produce tagatose efficiently and cheaply, achieving yields far higher than current methods. Tagatose delivers nearly the same sweetness as sugar with significantly fewer calories, minimal impact on blood sugar, and even potential benefits for oral and gut health.

MIT engineers have developed a pill that can wirelessly report when it’s been swallowed. Inside the capsule is a biodegradable antenna that sends a signal within minutes of ingestion, then safely dissolves. The system is designed to work with existing medications and could help doctors track adherence for high-risk patients. Researchers hope it will prevent missed doses that can lead to serious health consequences.

Plastic pollution is not just in oceans and soil. Scientists have now found enormous amounts of microscopic plastic floating through urban air, far exceeding earlier estimates. Road dust and rainfall play a major role in moving these particles through the atmosphere. The findings suggest the air may be one of the most important pathways for plastic pollution.

Some antibiotics stop bacteria from growing without actually killing them, allowing infections to return later. Scientists at the University of Basel created a new test that tracks individual bacteria to see which drugs truly eliminate them. When tested on tuberculosis and other serious lung infections, the method revealed big differences in how bacteria tolerate treatment. The findings could lead to more precise therapies and better predictions of treatment success.
