Oxygen is a cornerstone of chemistry, largely because it is so good at building the organic molecules that make up our world. Some oxygen-based compounds called peroxides are famous for being highly ...

As a recent leap in green chemistry, scientists have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen -- at close to room temperature. By fine-tuning the structure ...

Bacterial evolution and oxygen adaptation: A timeline built from genomic, fossil, and chemical data. Colors show oxygen states: anaerobic (blue), aerobic (red), and proportion of aerobic lineages in ...

Venus' atmosphere is notoriously hellish. Its air is corrosive and hot enough to melt lead. Its billowing clouds are poisonous to humans. Sometimes, it rains acid. But researchers just discovered that ...
