Scientists at Scripps Research have uncovered a molecular “switch” that appears to fuel the damaging brain inflammation seen in Alzheimer’s disease. They found that a protein called STING becomes chemically altered in a way that keeps the brain’s immune system stuck in overdrive, harming the connections between nerve cells.

Melanoma may not become steadily more dangerous with age as scientists once assumed. In a surprising discovery, researchers found that cancer spread was lowest in young mice, surged in middle-aged mice, and then dropped again in very old mice. The key appears to be a special type of immune cell that helps keep cancer dormant and prevents it from spreading.

Great apes appear to build friendships much like humans do. By studying grooming behavior, researchers discovered that chimpanzees and bonobos form close inner circles along with wider networks of weaker social connections. Chimpanzees focus on a few trusted partners and become more selective with age, while bonobos maintain a more egalitarian social style.

Scientists have developed a solar desalination system that turns seawater into drinking water without creating environmentally damaging brine. Special laser-textured metal panels use sunlight to evaporate water while automatically moving salt deposits away from the working surface, preventing clogging. The process was successfully tested with water from three oceans and can recover nearly all salts as solids. Those leftover materials could even become a source of valuable lithium for batteries.

Researchers have developed a compact quantum detector that makes terahertz radiation much easier to detect. A specially designed metasurface funnels incoming energy into tiny active regions, greatly strengthening the electrical signal produced. The approach boosted efficiency by roughly 20 times compared to earlier designs and could pave the way for more practical THz devices in healthcare, communications, and scientific research.

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 carbonate, a mineral that plays an important role in ocean health and carbon storage. For years, researchers believed fish handled this process on their own, but the new findings point to a hidden partnership between fish and microbes.

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 rely on Earth’s magnetic field for guidance. The discovery could solve a decades-old mystery about animal navigation and reveal an unexpected connection between immunity and sensing the environment.

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 also revealed changes in regions tied to appetite, cravings, and self-control. The results suggest the gut microbiome and brain may work together to influence weight-loss success.

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-inflammatory mode.

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 manufacturing techniques to overcome a major obstacle that has long blocked the production of true 3D chips.

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 strategy to help reduce long-term health risks associated with night shift work.

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 Bell Beaker migrants triggered another sweeping population transformation that extended all the way to Britain.

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 exhibits promising quantum properties at room temperature.

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 reductions in several key inflammatory proteins in their blood, while a control tomato juice did not produce the same effect.

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 reversed the memory deficits caused by lost sleep. The effect was remarkably targeted, helping the impaired circuit recover without overstimulating normal brain function.

A new room-temperature quantum device uses twisted light to entangle photons and electrons, overcoming one of the biggest hurdles in quantum technology. The breakthrough could pave the way for smaller, cheaper quantum systems with applications ranging from secure communications to future AI and computing platforms.

Scientists at Stanford may have uncovered a hidden reason our brains decline with age. Studying the ultra-short-lived turquoise killifish, researchers discovered that the cellular machinery responsible for building proteins begins to jam and malfunction over time. Tiny structures called ribosomes start colliding and stalling while reading genetic instructions, triggering a chain reaction that leads to faulty proteins and harmful clumps linked to diseases like Alzheimer’s.

Using cannabis edibles and alcohol together may make drivers far more impaired than either substance alone, according to new research from Johns Hopkins. Even more concerning, common field sobriety tests often failed to detect the cannabis-related impairment.

Scientists have discovered Labrujasuchus expectatus, a bizarre crocodile relative that looked more like an ostrich-like dinosaur than anything resembling a modern crocodile. It walked on two legs, had tiny arms, and sported a toothless beak—an unexpected combination for a member of the crocodile lineage.

A newly discovered raptor-like dinosaur from Patagonia is changing how scientists think about ancient predators. Named Kank australis, the 70-million-year-old dinosaur appears to have hunted fish much like modern herons, using a long, flexible neck and specialized vertebrae adapted for swift, precise movements.
