Slow orbital changes caused pulses in Earth's oxygen cycle 500 million years ago, which spurred explosions of animal life.

The ocean is a vast and complex web of intertwined systems. Chemistry, currents, temperature and nutrients all ebb and flow, each feeding back into the others. A multinational research team, led by UC ...

A research team from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (NIGPAS), along with collaborators, has found that long-term orbital variations occurring over ...

Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth – and it could help assess which other planets can develop ...

Recent studies and warnings from NASA have sparked global concern about the long-term sustainability of Earth’s oxygen supply. The implications of a diminishing oxygen reserve are profound, ...

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 ...

Our closest planetary neighbor Venus keeps leaking carbon and oxygen into space, mystifying scientists. Carbon and oxygen, among other gases, are being stripped from Venus' atmosphere after being ...
