Sir Fraser Stoddart, who taught chemistry at Northwestern and won the Nobel Prize in 2016, died at the age of 82.

Some molecules respond to light in a matter of seconds. In the case of this dithienylethene compound, ultraviolet light triggers a ring-forming reaction, turning the colorless solution deep red.

Using heavy water, the researchers could also selectively introduce deuterium atoms along with chlorine. The weightier hydrogen isotope is useful for probing reaction mechanisms, as well as studying ...

Activating agents enable the efficient preparation of organozinc complexes from zinc metal and organohalides, but their mechanisms had been obscured by the heterogeneous nature of these systems.

Wherever astronomers look, they see life’s raw materials—and hints at answers to one of the great mysteries of science.
