Regulatory crystallography
Date: Jan 1, 2010
Author: David Bradley
The structure and function of a chromatin regulator in yeast has been determined using X-ray crystallography. The structure provides new insights into epigenetics and may ultimately represent a target for the development of pharmaceutical therapies for a whole range of diseases.

Crystal first for enzyme
Date: Dec 15, 2009
Author: David Bradley
For the first time, researchers have used X-ray crystallography and NMR to directly visualize an enzyme in its low and higher-energy state and demonstrated the crucial role of interconversion between these states for catalysis. The study offers up new molecular sites as potential drug targets.

17th century mathematics and 21st century materials
Date: Nov 1, 2009
Author: David Bradley
Nanoparticles can self-assemble into quasicrystalline structures, according to researchers in the USA. The newly discovery structures could provide useful insights into how such non-periodic, and yet ordered, that lie half way between amorphous solids and regular crystals can arise.
