Climate Change: How Oxygen Deficiency Changes Metabolic Processes in the Ocean
A new study reveals how sulfur compounds are metabolized under oxygen-deficient conditions – and which microorganisms are responsible.
For Most US Drivers, EVs Offer Emissions Benefits and Cost Savings
Despite regional variability in climate, electricity sources, congestion, and the wide variation in individual driving patterns, electric vehicles generate less greenhouse gas emissions and do not cost more than comparable gas-powered vehicles for drivers and vehicle fleet owners in most parts of the United States, according to a new study...
As the Planet Warms, Why Is the Upper Atmosphere Cooling?
While our emissions are trapping heat near the surface of the Earth, they are having the opposite effect in the upper atmosphere.
Lab-Grown Algae Removes Microplastics From Water
Professor Susie Dai has engineered special algae to remove and reuse harmful microplastics from wastewater.

Scientists say this algae could remove microplastics from drinking water
Researchers created a special kind of algae that can grab microscopic plastic pollution out of water almost like a magnet. The algae produce limonene, an orange-scented oil that helps them bind to water-repelling microplastics, forming easy-to-remove clumps. As a bonus, the algae also clean wastewater while growing.
This strange giant dinosaur may change what we know about Jurassic titans
A bizarre new giant dinosaur discovered in Argentina is giving paleontologists a fresh look at how Jurassic titans evolved in the Southern Hemisphere. Bicharracosaurus dionidei stretched about 20 meters long and carried a strange mix of features seen in both Diplodocus and Brachiosaurus relatives. Scientists believe it could represent the...
Scientists discover hidden chemical signature that could reveal alien life
Scientists may have found a powerful new way to hunt for alien life — not by searching for specific molecules, but by looking for hidden patterns in how those molecules are organized. Researchers discovered that living systems leave behind a kind of chemical “fingerprint” in the statistical distribution of amino...
A supervolcano nearly wiped out humanity 74,000 years ago, but humans did something incredible
The Toba supereruption 74,000 years ago was so massive it may have plunged Earth into years of darkness and cold, leading some scientists to believe humanity nearly went extinct. Yet archaeological evidence from Africa and Asia suggests early humans were far more resilient than once thought. Instead of disappearing, some...
