These underground rodents are the first mammals found to actively choose air with lower-than-normal oxygen levels. Their remarkable ability to survive these conditions could offer a key model for rese ...

Marine life receives its oxygen from warm water on the ocean's surface, but if there's no mixing with the colder water sitting below, then bottom-dwelling marine life, like lobsters, are unable to ...

Researchers from the Broad Institute and Mass General Brigham have shown that a low-oxygen environment—similar to the thin air found at Mount Everest base camp—can protect the brain and restore ...

Danielle “Nellie” Bruns, an associate professor in the University of Wyoming’s Department of Zoology and Physiology, has received a five-year, $1.78 million research grant from the National Institutes ...

Rivers, streams, lakes, and reservoirs aren't just scenic parts of our landscape -- they're also vital engines for life on Earth. These inland waters 'breathe' oxygen, just like we do. But a new study ...

Long Island Sound experienced this year the lowest levels of hypoxia, or low oxygen, since monitoring of water quality began nearly four decades ago, the Long Island Sound Partnership announced.

Rivers, streams, lakes, and reservoirs aren’t just scenic parts of our landscape—they’re also vital engines for life on Earth. These inland waters ‘breathe’ oxygen, just like we do. But a new study ...
