Salamanders regrow entire limbs. Mice, like humans, grow scar tissue instead. A study published in Science now offers a ...

Some animals can regrow lost body parts. Salamanders and frog tadpoles can rebuild entire limbs after amputation. Mammals ...

A new approach reveals unexpected ways oxygen can bind to rare metals. Iron plays a central role in how the body uses oxygen. In hemoglobin, it binds dioxygen, a pair of oxygen atoms, allowing blood ...

Hyperbaric oxygen therapy was first used to treat decompression sickness for deep-sea divers. Now, it has grown to treat many medical problems, including carbon monoxide poisoning, gas gangrene, and ...

An article published this week in The Lancet medical journal found that more than half of the world’s population lacks access to safe and affordable medical oxygen services, and most people outside of ...

Iron and oxygen bind together throughout the body. Most famously, iron binds dioxygen, or two oxygens paired with each other, in hemoglobin that transports oxygen through blood. But iron-oxo compounds ...

Learn how oxygen’s early rise could have given complex life the energy boost it needed to evolve. The story of how complex life began is largely understood, but one contradiction has never quite fit.

Patients at high risk for pulmonary complications had similar support needs at 90 days with HFNOT or standard oxygen.

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 ...
