A new genomic analysis suggests that human language capacity emerged at least 135,000 years ago, with regional groups spreading across the globe around 100,000 years after that. The study, which examined 15 genetic studies, provides increasingly converging evidence about the timing of geographic splits among early human populations.

Wildland firefighters hit their STRIDE

Researchers from University of Utah introduced Simulating Travel Rates in Diverse Environments (STRIDE) model to predict walking travel times with unprecedented accuracy. The model considers slope steepness, vegetation density, and ground surface roughness for efficient routes.
