Turbulent era sparked leap in human behavior, adaptability 320,000 years ago

A new drill core analysis from the Smithsonian reveals a 400,000-year-old boom-bust landscape that drove early humans to abandon old tools, develop sophisticated technology, and broaden trade networks. The findings suggest climate variability was one of several environmental factors contributing to human adaptability.

Protected areas help waterbirds adapt to climate change

Protected areas facilitate wintering waterbird adaptation to climate warming, with species shifting faster inside protected areas. This suggests that protected area networks can contribute to expanding species ranges and preventing local extinctions.

Seeing no longer believing: the manipulation of online images

Researchers from Queensland University of Technology found that image editing software has the power to re-imagine history, and deadline-driven journalists lack tools to detect manipulated images. The study highlights the need for better verification tools and digital literacy to combat visual mis/disinformation online.
