Lasers tackle radioactive waste
Iodine-129, which has a half-life of 15.7 million years, has been transmuted into a lighter isotope with a half-life of just 25 minutes
First light for attophysics
Physicists have used an attosecond X-ray source to directly measure the decay of an electron cloud in an atom for the first time

Ultrafast electron diffraction shapes up
Now Ahmed Zewail and co-workers at the California Institute of Technology have developed a method of ultrafast electron diffraction that can resolve both the structure of a molecule and its dynamics d...
Water transfers energy at ultrafast rate
As a water molecule is excited by the laser pulse, it can only drop back to a less excited state by releasing the excess energy. This energy causes the O-H bonds to stretch and vibrate. As the bonds v...
