Berylliosis: X-ray clues to lung disease

New clues as to why inhalation of dust containing the group II metal, beryllium, causes a deadly immune response in the lungs of some people have emerged from X-ray diffraction, genetic, molecular binding and electrostatic studies. The research shows that a single amino acid change present in one lung protein, HLA-DP2, creates a pocket able to bind beryllium and sodium ions simultaneously and trigger the often lethal allergic disease berylliosis.

The molecular structures of fresh and used lubricating motor oils have been investigated by X-ray absorption fine structure spectroscopy measurements.

UV protection racket: X-ray revelations

The molecular building blocks of DNA absorb ultraviolet light strongly and so one might imagine that sunlight damage them all beyond repair, yet it does not. Now, scientists have used ultrafast X-ray Auger probing of photoexcited molecular dynamics to help them to understand the critical "relaxation response" that apparently protects DNA and the genetic information it encodes, from ultraviolet damage.

The 1962 book, Fifty Years of X-Ray Diffraction, dedicated to the International Union of Crystallography on the occasion of the commemoration meeting in Munich, July 1962, by P.P. Ewald (editor), and numerous crystallographers has been digitized and put on the web as a free site by the ICU.

In this article, the late Ron Jenkins, formerly of the International Center for Diffraction Data provides a brief but comprehensive overview of modern X-ray techniques.
