Rosalind Franklin was born on this day in 1920. Her contributions to the discovery of the structure of DNA were key; she took photos of DNA s structure using X-ray crystallography, and it was these photos which informed the work of Watson and Crick s model of DNA s structure. Sadly her contributions were not fully recognised until after her death, and she did not share in the award of the Nobel Prize for the discovery of DNA s structure as the prize is not awarded posthumously.
Here’s the weekly summary of both new chemistry research and studies that have been in the news. This week features research on how a polymer pulley system could make silicon anodes in lithium batteries workable, a 3D printed flower that uses the shape memory of a polyurethane polymer to bloom when exposed to light, and more. As always links to further articles and original research papers are provided below.

Hanging in the wardrobes of our flat, alongside our clothes, are a couple of small bags of dried lavender. Like many others, we keep them there to ward off clothes moths, but while offhandedly discussing this a couple of weeks ago I realised that I had absolutely no idea if there was scientific evidence to back up this repellent effect. So, I did what any good scientist would, and started a quest to find out whether lavender s anti-moth powers were the real deal, or as scientifically holey as the moth-eaten clothes it claims to ward against!
