A major study suggests that when you eat could play a key role in staying lean. People who fast longer overnight and start their day with an early breakfast were more likely to have a lower BMI years later. Scientists think this is because eating earlier aligns better with the body’s internal clock. But skipping breakfast as part of intermittent fasting didn’t offer the same advantage—and may eve…

Scientists searching for air pollution clues stumbled onto something unexpected: toxic MCCPs drifting through the air for the first time in the Western Hemisphere. The likely source—fertilizer made from sewage sludge—points to a hidden route for contamination.

Scientists have achieved the unthinkable by stabilizing a highly reactive molecule in water, confirming a decades-old theory about vitamin B1’s role in the body. The breakthrough not only solves a scientific mystery but could revolutionize greener chemical manufacturing.

Losing your sense of smell might signal Alzheimer’s far earlier than expected. Scientists found that immune cells in the brain actively destroy smell-related nerve fibers after detecting abnormal signals on their surfaces. This damage begins in early stages of the disease, well before cognitive decline. The discovery could help identify at-risk patients sooner and improve treatment timing.

Putting on weight earlier in life may be more dangerous than previously thought. Researchers found that early adulthood obesity significantly raises the risk of premature death, especially from major diseases like heart disease and diabetes. The longer the body carries excess weight, the greater the damage appears to be. Interestingly, cancer risk in women didn’t follow this pattern, suggesting o…

Researchers have uncovered why a rare blood clotting disorder can occur after certain COVID-19 vaccines or adenovirus infections. The immune system can mistakenly target a normal blood protein (PF4) after confusing it with a viral protein. This triggers clotting in extremely rare cases. The breakthrough means vaccines can now be redesigned to avoid this reaction while staying effective.

A common eye-health nutrient, zeaxanthin, may also help the body fight cancer more effectively. Scientists discovered it strengthens T cells and enhances the impact of immunotherapy treatments. Found in everyday vegetables and supplements, it’s safe, accessible, and shows strong potential as a cancer therapy booster. Human trials are the next step.

A breakthrough in microbiome research could change how colorectal cancer is detected—no colonoscopy required. Scientists used AI to map gut bacteria at an unprecedented level of detail, revealing subtle microbial patterns linked to cancer. By analyzing simple stool samples, their method identified 90% of cases, rivaling one of medicine’s most trusted diagnostic tools.

Alzheimer’s isn’t just one problem—it’s a tangled mix of biology, aging, and overall health. That’s why drugs targeting a single factor have fallen short, even as new treatments show modest benefits. Scientists are now pushing toward multi-pronged strategies, from gene editing to brain-cell rejuvenation and gut health interventions. The goal: stop treating Alzheimer’s as one disease and start tac…

Scientists have proposed a surprising new way to detect gravitational waves—by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different directions, leaving behind a detectable signature. The effect doesn’t change how much light atoms emit, which is why it’s gone unnoticed until now. If confirmed, this approach could lead to ultra-compact d…

A strange new kind of superconductivity has been uncovered in uranium ditelluride (UTe2), where electricity flows with zero resistance—but only under extremely strong magnetic fields that should normally destroy it. Even more surprising, the superconductivity disappears at first and then dramatically reappears at even higher fields, earning it the nickname the “Lazarus phase.”

Perovskite solar cells shouldn’t work as well as they do—but they do. Scientists have now discovered that defects inside the material actually help, creating networks that separate and guide electric charges efficiently. Using a novel imaging method, they revealed hidden structures acting like charge “highways.” This insight could unlock even more powerful, low-cost solar cells.

A new chip design from UC San Diego could make data centers far more energy-efficient by rethinking how power is converted for GPUs. By combining vibrating piezoelectric components with a clever circuit layout, the system overcomes limitations of traditional designs. The prototype achieved impressive efficiency and delivered much more power than previous attempts. Though not ready for widespread …

A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers propose a bold twist: dark matter might not be a single particle at all, but a mix of two different types that must interact with each other to produce detectable signals.

Dragonflies may see the world in a way that pushes beyond human limits—and surprisingly, they do it using the same molecular trick we evolved ourselves. Scientists discovered that these insects can detect extremely deep red light, even edging into near-infrared, thanks to a specialized visual protein strikingly similar to the one in human eyes. This ability likely helps them spot mates mid-flight…
