Work on Atom Trapping and Cooling Gets a Warm Reception in Stockholm
An atom at room temperature zips around at thousands of kilometers per hour. A hit by a single photon barely fazes it. Yet somehow, researchers have harnessed radiation forces to slow atoms to a few centimeters per second and trap them in place. For that feat, this year's Nobel Prize in Physics has been awarded.
Optical Frequency Measurement is Getting a Lot More Precise
A new trick for the repeated halving of optical frequency intervals now permits the measurement of optical atomic transitions with unprecedented accuracy.
New Results Suggest X‐Ray Emission is a Common Property of Comets

Ancient Stardust in the Laboratory
As it collapsed to form the Solar System, material in the solar nebula was churned up and homogenized. But not everything was lost in the mix …
The Foundation of the Silicon Age
The transistor was the product of basic research with a clear technological goal, but although the new technology was anticipated, its revolutionary impact was not.
The Moses of Silicon Valley
How did the epicenter of the semiconductor industry come to be located in California, a continent away from New Jersey, where the transistor was invented and most of the fundamental semiconductor technology was developed?
