Penn State researchers have uncovered a surprising twist in a foundational chemical reaction known as oxidative addition. Typically believed to involve transition metals donating electrons to organic ...

Potato-sized lumps of metal on the seafloor are generating oxygen, a new study has found. Scientists previously believed that oxygen was strictly formed as a byproduct of photosynthesizing plants.

Scientists have discovered a new way oxygen can form in carbon-dioxide-rich atmospheres of worlds beyond our own —- challenging assumptions about how we should search for life on other planets, and ...
