Scientists Witness Decision-Making in the Brain for the First Time
Neuroscientists have mapped the complete brain activity of mice during decision-making, capturing over half a million neurons and revealing that choices emerge from widespread coordination across many regions, not a single area. The study used implanted electrodes to monitor 95% of the brain volu...

Fasting Diet Triggers Dynamic Brain Changes
A study found that an intermittent energy restriction (IER) diet led to significant weight loss and dynamically altered both gut microbiome composition and activity in brain regions related to appetite and addiction. The research highlights a two-way communication between the gut and brain, where...

Human Eye Resolution Far Exceeds Previous Estimates
At typical living room distances, the human eye cannot fully resolve the pixel density of 4K or 8K TVs, making a standard 2K screen potentially comparable in visual experience for many consumers. The study found that the eye's resolution limit is higher than the traditional 60 pixels per degree, ...

Easter Island Statues Built by Small Clans, 3D Model Reveals
New 3D modeling of the Rano Raraku quarry suggests the moai were carved by decentralized family groups, not a single unified society, around 800 years ago. This digital reconstruction provides a comprehensive, shareable record of the site, allowing detailed virtual study of carving styles and ina...

Dogs Learn New Words by Eavesdropping on Owners
Some gifted dogs can learn new object names simply by overhearing casual conversations between their owners, a process known as fast mapping that was previously considered a primarily human trait. These dogs create and recall detailed multisensory mental records of objects, using features like ap...
