Across civilizations, people independently discovered that pairing grains with legumes created complete protein profiles—whether it was rice and soybeans in Asia, wheat and lentils in India, or corn and beans in the Americas. These solutions emerged from practical experience long before modern science...
Its name comes from the Greek root chroma (meaning color), for it appears bright red when viewed during a solar eclipse. The chromosphere extends for about 2,000 kilometers (1,200 miles) above the visible surface of the Sun.How Norman Lockyer Discovered Helium (& the Chromosphere & Nature...
Ekholm also noted that carbon dioxide acted in a layer high in the atmosphere, above water vapor layers, where small amounts of carbon dioxide mattered. All of this was understood well over a century ago. The Keeling curve tracks the changing carbon dioxide concentration in the atmosphere. ...

"They don't realize what we've discovered," van Andel replied. It was 1977. Scientists had just observed life, thriving, in an oceanic ridge at the bottom of the sea for the first time. They expected a desert; they found an oasis. Bizarre fish swam through dark smoke billowing ou...
Is there evidence of persistent low-level infection or unrelenting inflammation? Part of the challenge is that researchers like us are trying to study COVID-19’s after-effects while the world is still struggling with the acute phase of the pandemic, including the new Omicron variant. ...
