Laser Design Brings Attosecond Spectroscopy Closer
The field of ultrafast physics focuses on phenomena such as electron motions in molecules and atoms, which can take place on attosecond timescales. The ability to generate attosecond laser pulses would effectively permit electron motions to be "photographed."

Graphene Confines Light for Nanomolecular Sensing
Widely used for detecting larger molecules, IR absorption spectroscopy has been ineffective for detecting nanoscale molecules like proteins because mid-infrared wavelengths, around 6 µm, are much larger than the objects to be detected. This difference in scale can be overcome with graphene, which exhibits light confinement two orders of magnitude higher than other metals.
