Melting Antarctic ice may weaken a major carbon sink

Melting ice from West Antarctica once delivered huge amounts of iron to the Southern Ocean, but algae growth did not increase as expected. Researchers found the iron was in a form that marine life could not easily use. This means more melting ice does not automatically boost

The genetic turning point that made backbones possible

Scientists have uncovered a surprising genetic shift that may explain how animals with backbones—from fish and frogs to humans—became so complex. By comparing sea squirts, lampreys, and frogs, researchers found that key genes controlling cell communication began producing many

Sound machines might be making your sleep worse

Sound machines may not be the sleep saviors many believe. Researchers found that pink noise significantly reduced REM sleep, while simple earplugs did a better job protecting deep, restorative sleep from traffic noise. When pink noise was combined with outside noise, sleep

Reading the moon's diary, one speck of dust at a time

Magnetism on the moon has always been a bit confusing. Remote sensing probes have noted there is some magnetic signature, but far from the strong cocoon that surrounds Earth itself. Previous attempts to detect it in returned regolith samples blended together all of the rocks in

What's the point of a space station around the moon?

The Lunar Gateway is a planned space station that will orbit the moon. It is part of the NASA‑led Artemis program. Artemis aims to return humans to the moon, establishing a sustainable presence there for scientific and commercial purposes, and eventually reach Mars.
