Chemists have achieved a new feat in the realm of chemical design and synthesis: They've helped create the first example of a synthetic molecule, with an asymmetric oxygen atom as its centerpiece, ...

ESA’s Rosetta spacecraft has made the first in situ detection of oxygen molecules outgassing from a comet, a surprising observation that suggests they were incorporated into the comet during its ...

Dartmouth researchers have developed a cell phone-based tool that monitors tissue health by using a naturally occurring molecule to measure the oxygen level in cells. The tool could provide a simple ...

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 ...
