Cadmium accumulation in the shoots and roots of 93 weed species
Date: Aug 4, 2008
Author:
The cadmium contents of the shoots and roots of 93 weed species were determined by inductively coupled plasma optical emission spectroscopy and atomic absorption spectrometry, to determine the best species for cadmium phytoremediation.

Listening to tomographic tales
Date: Jul 15, 2008
Author: David Bradley
Researchers in the USA and The Netherlands have pieced together a picture of the most exquisite of molecular machines using electron-microscopic tomography. The team has for the first time obtained a three-dimensional structure of the gossamer-like filament of proteins found within the inner ear that gives us our sense of hearing and balance.

Soft test for hard water
Date: Mar 15, 2008
Author: David Bradley
An inexpensive, reusable, and portable hard water sensor based on a fluorescing strand of DNA could be possible thanks to research in Spain. The technology compares well in accuracy with complexiometric titration and atomic absorption spectroscopy but with none of their limitations.
