Seventeen studies coauthored by Gregg Semenza have been retracted, corrected, or raised for concern, and 15 more are currently under investigation.

To avoid the negative effects of ambient oxygen, researchers must grow cells in precise conditions.  

Discover reasons for avoiding low oxygen levels in cell cultures.

The first evidence of biologically produced elemental carbon inspires more questions than answers.  

Injecting oxygen-generating algae into tadpoles allows brain activity to continue in the absence of oxygen, researchers find.

Researchers find a widespread decline in dissolved oxygen levels in lakes, which is known to reshape ecosystems.

Researchers show that both mice and pigs are capable of oxygenating their blood via the colon—a capacity that, if shared by humans, could be leveraged in the clinic to minimize the need for mechanical ventilation.

Blue sharks don't dive as deeply in low-oxygen waters—which become more prevalent as oceans warm—effectively pushing them into areas of high fishing pressure.

In humans, higher oxygen levels during ventilation are tied to an altered bacterial composition in the lungs, and mouse experiments show a causative link.

For the Physiology or Medicine award, Peter Ratcliffe, William Kaelin, and Gregg Semenza are credited with figuring out molecular and genetic responses to oxygen levels.

The resilient rodents switch to fructose metabolism in order to survive for up to 18 minutes in anaerobic conditions.

By making oxygen more available, a benign bacterium can provide better growth conditions for a virulent one, according to a study.

Scientists make oxygen-filled microbubbles designed to increase tumor sensitivity to radiation.

New research uncovers previously unappreciated insights into the evolution of the well-studied energy-producing process.

Researchers have developed fast-dissolving particles that may one day prevent organ damage or death by instantly infusing oxygen into the blood.

A rare peek inside the subterranean home of the naked mole-rat

What can a twentysomething naked mole-rat tell us about fighting pain, cancer, and aging?

Scientists discover that ancestors of the unicellular fungi can synthesize essential biomolecules with only trace levels of O₂.

The fundamental question of how cells sense oxygen has implications for embryogenesis, cancer, stroke, diabetes, and other ischemic diseases.
