One of Earth’s most powerful supervolcanoes is refilling with fresh magma

13:44
Deep beneath Japan’s Kikai caldera, a massive magma reservoir is refilling 7,300 years after one of the most powerful volcanic eruptions in Earth's recent geological history. Scientists used underwater seismic surveys to reveal a vast store of magma that appears to have accumulated since the ancient catastrophe. The discovery could help explain how supervolcanoes like Yellowstone and Toba rebuild…

Nearly 20% of Switzerland’s glacier ice has vanished in just five years

13:44
Switzerland’s glaciers are disappearing at an alarming rate, losing more than 5% of their ice volume in 2026 alone. Some of the country’s most famous glaciers experienced their worst melting on record, while several smaller glaciers vanished completely. Nearly 20% of Switzerland’s glacier ice has disappeared in just five years, driven by unusually snowless winters and extreme summer heat.

Dental implants can hijack your immune system, scientists discover

13:44
Researchers have uncovered a surprising reason dental implant infections often resist antibiotics: the implants themselves can contribute to the problem. Bacteria corrode titanium implants, releasing microscopic particles that hijack immune cells, trigger destructive inflammation, and accelerate jawbone loss.

Breakthrough PTSD treatment achieves 68% remission rate in clinical trial

13:44
A newly FDA-cleared PTSD treatment uses personalized brain mapping and magnetic stimulation to target abnormal brain activity, with a clinical trial reporting a 52% reduction in symptoms and 68% remission. Researchers believe the technology could transform PTSD care and pave the way for more precise treatments for other mental health conditions.

MIT scientists build a tiny robot that swims using living muscle cells

13:44
MIT engineers have built a paper-thin swimming robot powered by living muscle cells that respond to flashes of light, allowing it to swim and steer through water. The breakthrough could pave the way for tiny, self-healing biological robots capable of exploring fragile environments that ordinary machines cannot safely navigate.

Scientists discover a surprising double benefit of exercise for Parkinson’s

13:44
A seven-year study found that people with Parkinson’s disease who were more physically active experienced slower declines in memory, thinking, and movement abilities. Those exercising more than eight hours per week showed almost no average cognitive decline, suggesting that staying active may offer important benefits as the disease progresses.

Scientists discover a hidden messaging system deep inside the brain

13:44
A tiny region deep within the brain has surprised scientists by revealing a remarkably sophisticated communication system. Previously thought to broadcast the same chemical signal throughout the brain, this region actually sends targeted messages that help control learning, attention, and behavior, according to new research in mice.

A tiny defect in a crystal reveals a big quantum surprise

13:44
Researchers have solved a long-standing challenge in understanding how tiny defects in materials like diamond and silicon carbide behave when exposed to light. Their new computational method revealed a surprisingly important energy-loss mechanism in silicon carbide that scientists had previously underestimated. The finding helps explain a mystery that has puzzled researchers for years and could i…

Cambridge scientists create a $10 chip that could put a medical lab on your wrist

5:43
Cambridge researchers have created a groundbreaking $10 optical sensor that delivers the precision of laboratory equipment in a device small enough for wearable technology. It identified foods, plastics, and medicines with 100% accuracy in tests and demonstrated the ability to monitor blood glucose, alcohol, and other health markers without invasive procedures.

Nearly 3,000 exploding stars challenge our understanding of the Universe

5:43
A massive analysis of 2,884 exploding stars has uncovered new evidence that dark energy, the mysterious force accelerating the universe’s expansion, may change over time. The findings challenge a cornerstone of modern cosmology and could reshape our understanding of how the universe works.

40 years later, Chernobyl's nuclear fallout is not what scientists expected

5:43
Forty years after the Chornobyl disaster, tiny radioactive particles still linger in the soil, carrying a dangerous legacy. Using powerful X-rays, scientists discovered that some of these particles have remained surprisingly stable, trapping radioactive substances inside instead of releasing them into the environment.

Scientists discover a hidden immune weapon against deadly lung cancer

5:42
Researchers have uncovered a hidden immune defense capable of attacking small cell lung cancer, an extremely aggressive disease that often escapes conventional treatments. The specialized immune cells can recognize and destroy cancer cells even when tumors have disguised themselves from the immune system.

Millions take fish oil for brain health. A two-year study found no benefit

5:42
A surprising two-year clinical trial found that fish oil supplements successfully delivered omega-3s to the brain but failed to improve memory or protect against Alzheimer's-related brain shrinkage. Researchers suspect that getting these nutrients through a healthy diet may offer benefits that supplements alone cannot provide.

Birds are more afraid of women than men. Scientists have no idea why

14:50
Scientists have uncovered a strange pattern in urban bird behavior: Across five European countries and 37 species, birds consistently fled sooner when approached by women than men. Researchers have no clear explanation for the difference, raising intriguing questions about how birds recognize and respond to humans.

Oxford scientists discover how viruses build themselves without a blueprint

14:50
Scientists have captured virus-like particles assembling themselves step by step, revealing how a surprisingly simple process of trial and error produces complex structures with remarkable precision. The discovery uncovers a crucial molecular turning point that speeds up assembly and could lead to new ways to disrupt viruses and develop vaccines.
