Supercontinuum generation and soliton dynamics milestone achieved

A research team led by Fetah Benabid, University of Bath, has observed for the first time the simultaneous emission of two resonant dispersive waves by optical solitons (waves that maintain their shape while traveling at ...

Probing question: What is a molecular clock?

It doesn't tick, it doesn't have hands, and it doesn't tell you what time of day it is. But a molecular clock does tell time -- on an epoch scale. The molecular clock, explained S. Blair Hedges, is a tool used to calculate ...
