Focus on X-rays: No more data sacrifice
Date: Jun 1, 2012
Author: David Bradley
The equivalent of a new pair of spectacles has come in the form of an advanced method for analysing the so-called "discarded" X-ray data from a crystallographic study. The analytical technique could help improve structural studies on biopolymers including proteins and nucleic acids.

Complex answer: Finding hepatitis C antivirals
Date: Apr 1, 2012
Author: David Bradley
Hepatitis C is a chronic infectious disease that afflicts some 170 million people worldwide, causing chronic liver disease and liver cancer. Chemists at the University of California, San Diego have finally obtained the first high- resolution crystal structure of a compound that binds to the genetic material of the hepatitis C virus and blocks its replication.
