The Mass Spectrometer's Guide to the Galaxy (well, Mars)
Date: Jul 15, 2005
Author: David Bradley
Like spotting the telltale signs of a campsite in a back-country woodland, a new chemical guidebook and spectral imaging system will allow a future Martian rover to spot the signs of microbial life on the red planet.

Taking spectroscopy by surprise
Date: Jul 1, 2005
Author: David Bradley
Tracking molecular excitations is now possible using the new technique of 2D electronic spectroscopy, which means light-induced changes can now be tracked, and could sound a death knell for other conventional spectroscopic techniques.

Weighing up the new kilogram
Date: Jun 15, 2005
Author: David Bradley
A new definition of the kilogram could improve the precision of a wide range of instrumentation by providing researchers with a mass unit based on a fundamental property of a defined quantity of matter rather than the weight of an piece of platinum-iridium alloy housed in a French basement.
