On this day back in 1802, Germain Hess was born in Switzerland. Hess would go on to do important work in the field of thermochemistry, the part of chemistry concerned with energy changes in chemical reactions. His work led to the eponymous Hess’s law, explained in the graphic above. Hess also analysed the mineral silver telluride, which was named Hessite in his honour. […]

Here in the UK, a completely un-British heatwave finally came to a thundery end last weekend. Having already looked at the chemistry behind the smell of rain, here’s a look at some of the science behind thunderstorms. How does lightning happen, what gives it its blue-violet tinge, and what does it have to do with plant growth?
Volcanic eruptions can be unpredictable and destructive. In the latest edition of Periodic Graphics in Chemical and Engineering News, we investigate the types of lava produced in volcanoes and the gases ejected during eruptions. Click here to view the full graphic on the C&EN site.
“Spinach is a good source of iron” – a myth, but a surprisingly persistent one. The story behind the myth and the chemistry that debunks it are fascinating. Here we look at both, as well as the chemical explanation behind the ‘spinach teeth’ phenomenon.
It’s the World Cup final between France and Croatia today! Here’s an updated version of the chemistry of football shirts post, taking a look at the polymeric materials that make up a shirt.
