A major addition to chemists' toolkit for building new molecules

Chemists at Scripps Research have solved a long-standing problem in their field by developing a method for making a highly useful and previously very challenging type of modification to organic molecules. The breakthrough ...

Investigating the rise of oxygenic photosynthesis

About 2.4 billion years ago, at the end of the Archean Eon, a planet-wide increase in oxygen levels called the Great Oxidation Event (GOE) created the familiar atmosphere we all breathe today. Researchers focused on life's ...

Comet inspires chemistry for making breathable oxygen on Mars

Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason—we humans need molecular oxygen (O2) to breathe, and space is essentially devoid of it. Even on other planets with ...

Chemical engineers explain oxygen mystery on comets

A Caltech chemical engineer who normally develops new ways to fabricate microprocessors in computers has figured out how to explain a nagging mystery in space—why comets expel oxygen gas, the same gas we humans breathe.
