A large-scale animal study from 2021 revealed something interesting about yawning: Vertebrates with larger brains and more neurons tend to have longer-lasting yawns. Researchers collected data on 1,291 separate yawns from zoo trips and online videos, covering a total of 55 mammal species and 46 bird species. They found “robust positive correlations” between how long

The cloudy material that drifts from chimney-like vents in the ocean floor could harbor microscopic lifeforms scientists never even knew existed. The ridges of the ocean seabed are littered with fissures called hydrothermal vents that spew hot, deep-Earth fluids containing hydrogen sulfides, methane, and hydrogen out into the ocean. Around the warm periphery of these

The bright, white tail feathers of the otherwise inconspicuous Eurasian woodcock (Scolopax rusticola) are the most reflective on record. An international team of researchers found that the woodcock’s white patches reflected up to 55 percent of light, making their feathers around 30 percent more reflective than any other bird previously measured. Woodcocks are mottled brown

Earth’s surface is the “living skin” of our planet – it connects the physical, chemical, and biological systems. Over geological time, landscapes change as this surface evolves, regulating the carbon cycle and nutrient circulation as rivers carry sediment into the oceans. All these interactions have far-reaching effects on ecosystems and biodiversity – the many living
