One of the long-standing goals being pursued by chemists has been to succeed in following and directly visualising how the structures of molecules change when they undergo complex chemical ...

A team of researchers has discovered a new chemical reaction for producing one of the four nucleotides, or building blocks, needed to build DNA. The reaction includes an unusual first step, or ...

When you get right down to the atomic scale, things happen much faster than we’re used to. That makes it hard to actually see what happens during chemical reactions, so researchers at Harvard have ...
