A group of researchers have created an unusual material -- a soft crystal made of molecules known as a catenanes-- that behaves in a novel way that could be used in applications such as films that ...

In 2016, experts writing in Nature listed seven breakthroughs in how we process chemicals that could change the world for the better. We believe we’ve just ticked one of those off the list. We found a ...

Earth’s radiation can send some molecules spinning or vibrating, which is what makes them greenhouse gases. This infographic explains how relatively few heat-trapping molecules can have a planetary ...
