Very few discoveries truly revolutionise the way we look at the world.
However, the discovery of the structure of DNA is one of them. And it was on this day in 1953, that the structure of DNA was published in the journal Nature.
This discovery is often seen as controversial, not due to its scientific content, but the fact that the work was largely attributed to one team; Watson and Crick.
This work was published at the same time in a number of papers in Nature by three teams: Watson and Crick; Wilkins, Stokes, and Wilson; and Franklin and Gosling.
The key break through for Watson and Crick’s work came from Rosalind Franklin who studied DNA using X-ray crystallography, but this was largely unacknowledged at the time. In 1962 Crick and Watson, along with Wilkins, received a Nobel Prize for their discovery. Rosalind had died four years earlier so was not eligible for a Nobel Prize.
So to ensure that we celebrate all their work today, I thought I would bring to your attention a recent innovation, which would not have been possible without this major discovery.
A team of scientists and engineers from the University of Chicago (UChicago) and the Massachusetts Institute of Technology (MIT), US, have developed a new spectroscopy method that could prove useful in developing the next generation of anti-viral treatments.
The team used synthetically designed shape-shifting molecules which are able to resemble natural DNA bases, but can convert into a different molecular structure by repositioning their hydrogen atoms on nitrogen and oxygen atoms.
