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...

Nanotyrannus: A Separate Species, Not a Young T. Rex
New research confirms that controversial dinosaur fossils belong to a separate species called Nanotyrannus, not juvenile Tyrannosaurus rex, reshaping understanding of tyrannosaur diversity in the Late Cretaceous. The study, led by Nicholas Longrich and Evan Saitta, used growth ring analysis to sh...

Scientists Unlock Secret of Ancient Maya Eclipse Predictions
The Maya repurposed existing lunar month tables in the Dresden Codex for long-term eclipse prediction, rather than creating a unique eclipse table, as revealed by a recent study. Their advanced astronomical knowledge was preserved in codices like the Dresden Codex, which contains accurate eclipse...

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...
