A switch from predominantly undersea volcanoes to a mix of undersea and terrestrial ones shifted the Earth’s atmosphere from devoid of oxygen to one with free oxygen, according to geologists. “The ...

As antimicrobials, graphene materials (GMs) may have advantages over traditional antibiotics due to their physical mechanisms of action which ensure less chance of development of microbial resistance.

Astrophysicists outline the links between atmospheric oxygen and the potential rise of advanced technology on distant planets. In the quest to understand the potential for life beyond Earth, ...

Oxygen fills the air today, but for most of Earth’s early history it barely existed. Scientists say the atmosphere did not hold steady oxygen until about 2.33 billion years ago, during the Great ...

A research team develops manganese-based cathodes with longer lifespan by suppressing oxygen release. A research team led by Professor Jihyun Hong from the Department of Battery Engineering Department ...

Coined by astrophysics Adam Frank and Amedeo Balbi, the “oxygen bottleneck” describes the critical threshold that separates worlds capable of fostering technological civilizations from those that fall ...
