Wild Chimps Caught on Camera Sharing Alcoholic FruitRemote cameras in Africa have captured the first images and video of wild chimpanzees eating and sharing fermented fruit that contains alcohol.

AI Uncovers New Cause of Alzheimer’s - Neuroscience NewsResearchers have discovered that a gene previously seen as a biomarker for Alzheimer’s disease, PHGDH, actually plays a causal role by disrupting gene regulation in the brain.

Circular breathwork induces altered states of consciousness linked to improved mental healthResearchers from the Ernst Strüngmann Institute for Neuroscience, the MIND Foundation, alongside other collaborators, have found that reductions in carbon dioxide saturation during circular breathwork sessions were correlated with the emergence of altered states of consciousness. Altered states resembled those reported in psychedelic experiences and were associated with improvements in psychological well-being and reductions in depressive symptoms.

Circular Breathing Explained | Aims, Techniques and Health BenefitsCircular Breathing involves breathing in slowly with deep and full breaths and breathing out slowly and fully, without applying a deliberate pause between inhale and exhale.

The U.S. Is Reportedly Unable To Make Drones Without Components From ChinaThe United States faces a significant challenge in drone manufacturing due to its heavy reliance on Chinese components. Rising tensions over Taiwan an

Scientists 'Tattoo' Tardigrades in Nanotechnology BreakthroughA new technique has allowed researchers to tattoo patterns onto the tiny bodies of living tardigrades.

41,000 Years Ago, Humans Used Sunscreen, Clothes To Beat Deadly Solar RadiationRoughly 41,000 years ago, our planet went through a cosmic shake-up not a meteor strike or volcanic eruption, but a weakening of Earth’s magnetic fi

NASA Reveals First-of-Its-Kind Image of Mars Rover Seen From SpaceSince August 2012, a lonely robot has been traversing the rocky surface of Mars on a mission of science.

What’s Going On Inside Io, Jupiter’s Volcanic Moon? | Quanta MagazineRecent flybys of the fiery world refute a leading theory of its inner structure — and reveal how little is understood about geologically active moons.

Why Belly Fat Expands With Age, and How to Target It - Neuroscience NewsNew research uncovers that aging activates a new type of stem cell that rapidly produces fat cells, explaining why belly fat often expands in middle age.

Scientists Scanned the Brains of Authoritarians and Found Something WeirdPeople who support authoritarianism have, according to a new study, something weird going on with their brains.

Two cities stopped adding fluoride to water. Science reveals what happenedAs calls to end fluoride in water get louder, changes to the dental health of children in Calgary, Canada, and Juneau, Alaska, may provide a cautionary tale.

First atomic map of potato pathogen reveals potential infection mechanismPlants are susceptible to a wide range of pathogens. For the common potato plant, one such threat is Pectobacterium atrosepticum, a bacterium that causes stems to blacken, tissues to decay, and often leads to plant death, resulting in significant agricultural losses each year.

Female bonobos keep males in check -- not with strength, but with solidarityFemale bonobos team up to suppress male aggression against them -- the first evidence of animals deploying this strategy. In 85% of observed coalitions, females collectively targeted males, forcing them into submission and shaping the group's dominance hierarchy. This is the first study to test drivers of female dominance in wild bonobos. The study examined 30 years of demographic and behavioral data across six wild bonobo communities. The study suggests that power isn't solely determined by physical strength. It can be driven by social intelligence and coalition-building by females.

Researchers find oldest ant known to science—113-million-year-old ‘hell ant’ with scythe jawsThis fossil is 13 million years older than any ant fossil found before—and reveals a sophisticated predator that lived alongside the dinosaurs.
