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.

Selenium and sperm

Date: Nov 15, 2009

Author: David Bradley

X-Ray fluorescence microscopy reveals details of the role of selenium in spermatogenesis. The new research lends support to earlier studies and anecdotal evidence regarding this otherwise difficult to image element.

Quantitative elemental analysis of individual particles with the use of micro-beam X-ray fluorescence method and Monte Carlo simulation

Date: Nov 9, 2009

Author:

A Monte Carlo method was developed and combined with micro-beam X-ray fluorescence for the determination of the chemical composition of individual particles and was applied to a collection of glass micro-spheres,

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.

Biochemical translator nets Nobel Prize

Date: Oct 13, 2009

Author: David Bradley

Three scientists, one in the UK, one in Israel, the other in the US, are the joint recipients of the 2009 Nobel Prize for Chemistry "for studies of the structure and function of the ribosome".

Analysis of intraindividual and intraspecific variation in semicircular canal dimensions using high-resolution x-ray computed tomography

Date: Oct 12, 2009

Author:

The intraspecific and intraindividual variations in the sizes of the three semicircular canals in the right and left temporal bones of the short-tailed shrew were measured on a high-resolution X-ray computed tomography system.
