Low-oxygen zones in Danish seas double in a year

The area of Danish seas affected by low oxygen levels—a problem triggered by climate change—has doubled in the space of a year, according to a university report published Friday.

How some tissues can 'breathe' without oxygen

Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells' mitochondria. Through a series of reactions called the electron transport chain, electrons are passed along in a sort ...

How bacteria survive low oxygen environments

Researchers from ITQB NOVA, in collaboration with the Institut Pasteur in Paris, have shed light on the mechanisms that allow Clostridioides difficile, a pathogen that can only grow in oxygen-free environments, to be able ...

Warming climate will impact dead zones in Chesapeake Bay

In recent years, scientists have projected increasingly large summer dead zones in the Chesapeake Bay, areas where there is little or no oxygen for living things like crabs and fish to thrive, even as long-term efforts to ...
