Cracking the case of the missing molecules

When scientists moved from manipulating atoms to messing with molecules, molecules started to disappear from view. Professor Kang-Kuen Ni has figured out why.

Cosmic rays may be behind life’s mirrored molecules

Radiation from space may have left a mark on early life, researchers say. It could explain chirality, or why molecules have left- and right-handed versions.

Harvard scientists use optical tweezers to capture ultracold molecules

Using precisely focused lasers that act as “optical tweezers,” Harvard scientists have been able to capture and control individual ultracold molecules – the eventual building-blocks of a quantum computer – and study the collisions between them in more detail than ever before.
