New research shows that poor sleep could make the brain appear years older than it really is. Using MRI scans and machine learning, scientists found a clear link between unhealthy sleep patterns and accelerated brain aging.

Flu detection could soon be as simple as chewing gum. Scientists have created a molecular sensor that releases a thyme-like flavor when it encounters influenza, offering a low-tech, taste-based alternative to nasal swabs. Unlike current tests that are slow, costly, or miss early infections, this method could catch the flu before symptoms appear.

Billions of years ago, Earth’s atmosphere was hostile, with barely any oxygen and toxic conditions for life. Researchers from the Earth-Life Science Institute studied Japan’s iron-rich hot springs, which mimic the ancient oceans, to uncover how early microbes survived. They discovered communities of bacteria that thrived on iron and tiny amounts of oxygen, forming ecosystems that recycled elements like carbon, nitrogen, and sulfur.

A massive NIH-backed study reveals that COVID-19’s toll on smell may be more widespread and lasting than most realize. Even patients without noticeable symptoms often performed poorly on scent tests, raising safety and health concerns. Because smell loss can signal deeper neurological issues, experts are calling for routine testing and exploring new treatments.

A massive quake struck Calama, Chile, in 2024, surprising scientists with its unusual depth and destructive power. Unlike typical deep quakes, it broke past thermal limits and triggered an intense “thermal runaway” rupture. Researchers say the event challenges long-held theories and highlights the need for improved monitoring and preparedness. Their findings could shape how we predict and respond to future seismic threats worldwide.

New lunar samples from the far side reveal it formed from cooler magma than the near side, confirming the Moon’s interior is not uniform. Researchers suggest fewer heat-producing elements on the far side explain the difference. Theories range from ancient cosmic collisions to Earth’s gravitational pull. These discoveries bring us closer to solving the Moon’s long-standing “two-faced” mystery.

In 2020, California’s Creek Fire became so intense that it generated its own thunderstorm, a phenomenon called a pyrocumulonimbus cloud. For years, scientists struggled to replicate these explosive fire-born storms in climate models, leaving major gaps in understanding their global effects. Now, a new study has finally simulated them successfully, reproducing the Creek Fire’s storm and others like it.

Penn researchers found that psilocybin can calm brain circuits tied to pain and mood, easing both physical suffering and emotional distress in animal studies. The compound works in the anterior cingulate cortex, bypassing injury sites and offering a dual benefit for pain and depression. Unlike opioids, psilocybin is non-addictive and may provide relief lasting weeks.

Scientists confirmed that pianists can alter timbre through touch, using advanced sensors to capture micro-movements that shape sound perception. The discovery bridges art and science, promising applications in music education, neuroscience, and beyond.

Gaslighting, often seen as a form of manipulation, has now been reframed by researchers at McGill University and the University of Toronto as a learning process rooted in how our brains handle prediction and surprise. Instead of merely being explained through outdated psychodynamic theories, this new model highlights how trust and close relationships can be exploited by manipulators who repeatedly undermine a person’s confidence in their own reality.

A team in Sweden has unraveled the hidden structure of a promising solar material using machine learning and advanced simulations. Their findings could unlock durable, ultra-efficient solar cells for a rapidly electrifying world.

A 430-million-year-old fossil has rewritten leech history, showing they are at least 200 million years older than previously believed. Unlike today’s bloodsucking leeches, their ancient ancestors likely hunted small marine animals using a tail sucker rather than piercing skin.

Swiss glaciers lost nearly 3% of their volume in 2025, following a snow-poor winter and scorching summer heatwaves. The melt has been so extreme that some glaciers lost more than two meters of ice thickness in a single season. Scientists caution that the decline is destabilizing mountains, raising risks of rock and ice avalanches. Long-term monitoring efforts are now more critical than ever.

BMJ Group has pulled a widely reported apple cider vinegar weight-loss study after experts uncovered major flaws in its data and analysis. Attempts to replicate the results failed, and irregularities raised questions about the trial’s reliability. The authors admitted mistakes and agreed to the retraction, while editors stressed the importance of transparency and warned against citing the discredited findings.

Zeaxanthin, best known for eye health, has been found to boost the tumor-killing power of T cells. Researchers showed it strengthens T-cell receptors, enhances immune signaling, and improves the effects of immunotherapy. Found naturally in foods like spinach and peppers, it’s safe, accessible, and now a promising candidate for cancer treatment trials.

Fresh analysis of Cassini data has revealed new complex organic molecules inside ice grains spewing from Enceladus. These discoveries strengthen the case that the moon’s underground ocean hosts chemistry similar to life’s building blocks on Earth. Scientists now believe Enceladus could be habitable, and plans are underway for a European mission to sample its surface and jets.

Fungi may have shaped Earth’s landscapes long before plants appeared. By combining rare gene transfers with fossil evidence, researchers have traced fungal origins back nearly a billion years earlier than expected. These ancient fungi may have partnered with algae, recycling nutrients, breaking down rock, and creating primitive soils. Far from being silent background players, fungi were ecosystem engineers that prepared Earth’s surface for plants, fundamentally altering the course of life’s history.

A new AI tool called DOLPHIN exposes hidden genetic markers inside single cells, enabling earlier detection and more precise treatment choices. It also sets the stage for building virtual models of cells to simulate disease and drug responses.

A powerful new AI tool called Diag2Diag is revolutionizing fusion research by filling in missing plasma data with synthetic yet highly detailed information. Developed by Princeton scientists and international collaborators, this system uses sensor input to predict readings other diagnostics can’t capture, especially in the crucial plasma edge region where stability determines performance. By reducing reliance on bulky hardware, it promises to make future fusion reactors more compact, affordable, and reliable.

Scientists have found a way to supercharge the immune system’s T cells by blocking a protein called Ant2, essentially rewiring how these cells generate energy. This metabolic reprogramming makes them more resilient, faster, and deadlier against tumors.
