Around 1550, life on Rapa Nui began changing in ways long misunderstood. New research reveals that a severe drought, lasting more than a century, dramatically reduced rainfall on the already water-scarce island, reshaping how people lived, ...
Methane levels in Earth’s atmosphere surged faster than ever in the early 2020s, and scientists say the reason was a surprising mix of chemistry and climate. A temporary slowdown in the atmosphere’s ability to break down methane allowed the gas ...
Forests around the world are quietly transforming, and not for the better. A massive global analysis of more than 31,000 tree species reveals that forests are becoming more uniform, increasingly dominated by fast-growing “sprinter” trees, while ...
A common iron mineral hiding in soil turns out to be far better at trapping carbon than scientists realized. Its surface isn’t uniform — it’s a nanoscale patchwork of positive and negative charges that can grab many different organic ...
Researchers have found a surprising way to turn sunflower oil waste into a powerful bread upgrade. By replacing part of wheat flour with partially defatted sunflower seed flour, breads became dramatically richer in protein, fiber, and ...
Tiny marine plankton that build calcium carbonate shells play an outsized role in regulating Earth’s climate, quietly pulling carbon from the atmosphere and helping lock it away in the deep ocean. New research shows these microscopic engineers are ...
Pumas returning to Patagonia have begun hunting mainland penguins that evolved without land predators. Scientists estimate that more than 7,000 adult penguins were killed in just four years, many of them left uneaten. While the losses are dramatic, ...
Arctic sea ice helps cool the planet and influences weather patterns around the world, but it is disappearing faster than ever as the climate warms. Scientists have now developed a new forecasting method that can predict how much Arctic sea ice will ...
A new study reveals that chemicals used to replace ozone-damaging CFCs are now driving a surge in a persistent “forever chemical” worldwide. The pollutant, called trifluoroacetic acid, is falling out of the atmosphere into water, land, and ice, ...
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 ...
Researchers have found that manganese, an abundant and inexpensive metal, can be used to efficiently convert carbon dioxide into formate, a potential hydrogen source for fuel cells. The key was a clever redesign that made the catalyst last far ...
As demand for critical metals grows, scientists have taken a rare, close look at life on the deep Pacific seabed where mining may soon begin. Over five years and 160 days at sea, researchers documented nearly 800 species, many previously unknown. ...
