A surprising new discovery suggests that tiny microbes living inside fish may be helping shape the chemistry of the world's oceans. Scientists found evidence that bacteria in the guts of marine fish work alongside their hosts to produce calcium ...

Scientists have uncovered a surprising navigation system in pigeons: iron-filled immune cells in the liver that may act like tiny magnetic sensors. Birds deprived of these cells struggled to find their way home under overcast skies, indicating they . ...

Losing weight may involve rewiring the gut and the brain at the same time. In a study of obese adults, an intermittent fasting-style diet led to significant weight loss, healthier metabolic markers, and notable shifts in gut bacteria. Brain scans ...

A new study suggests fish oil may help reduce insulin resistance even in people who aren't obese. In diabetic rats, omega-3 supplementation improved blood sugar levels, cholesterol, and inflammation by shifting immune cells into a more anti ...

As traditional chip miniaturization slows, researchers have found a way to pack more computing power into the same space by stacking silicon circuits in multiple layers. The new process uses ultra-thin silicon membranes and low-temperature ...

A new study suggests melatonin supplements may help night shift workers boost their body's DNA repair processes, potentially offsetting some of the damage linked to working overnight. The findings are early but raise the possibility of a simple ...

New DNA evidence shows that Europe's hunter-gatherers and early farmers interacted far more closely than previously thought, with women likely playing a crucial role in spreading farming across northwestern Europe. Centuries later, the arrival of ...

By stacking custom-designed silver nanoparticles like nanoscale LEGO bricks, scientists stabilized a mysterious crystal phase that had never been observed before. The material not only solves a longstanding puzzle in materials science but also ...

A specially formulated tomato-soy juice packed with natural plant compounds may help calm inflammation linked to obesity, according to a new clinical study. Healthy adults with obesity who drank the juice daily for four weeks saw significant ...

Scientists discovered that sleep deprivation damages a key brain circuit responsible for social memory, making it harder to recognize familiar individuals. In laboratory studies, caffeine restored communication between neurons in this pathway and ...
