Chemists design new molecule, with oxygen as the star of the show      (via sciencedaily.com) 

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, that remains stable and nonreactive -- despite this type of molecule's tendency in nature to be touchy and short-lived. What makes this feat unique is that the new molecule is chiral, which means it has a non-superimposable mirror image.
