DNA 65 years on: light switch molecules to diagnose disease

It’s 65 years since Watson and Crick published their world-changing paper on the structure of DNA – a discovery they and Rosalind Franklin made using a technique called X-ray diffraction. To mark the anniversary we spoke to Dr James Hall, who uses the same technique today to study molecules which light up when they detect damaged DNA. This could pave the way for future diagnostic tests for diseases such as cancer.
