The molecular mechanisms behind circadian rhythms

The first of this year’s Nobel Prizes in Science was announced today! This year’s prize in physiology or medicine was awarded to Jeffrey C. Hall, Michael Rosbash, and Michael W. Young for their research into the molecular mechanisms behind circadian rhythms more

Detecting gravitational waves from black hole collisions

This year’s second Nobel Prize in the sciences was awarded today. The prize for physics was awarded to researchers who contributed to the observation of gravitational waves, ripples in space-time that were originally created by colliding black holes over a billion years ago. more

Revealing the structures of biomolecules with cryo-electron microscopy

The last of this year’s Nobel Prizes, the Nobel Prize in Chemistry, was awarded today. This year’s prize went to the development of cryo-electron microscopy, a technique that allows the structures of biomolecules to be revealed where other techniques fail. It also gives scientists insights ... more

A Guide to Acids, Acid Strength, and Concentration

Even if you’re not a chemist, you’ll doubtless remember learning about acids back in school. They’re routinely described as strong or weak, concentrated or dilute. But what’s the difference between a strong acid and a concentrated acid? Explaining that is a little trickier than it sounds; i ... more

Developing Cheaper Lab-on-a-chip Devices with 3D Printing

Today’s graphic takes a look at the research of Sarah Hampson, a PhD student from Loughborough University who’s currently investigating 3D printed lab-on-a-chip devices and their potential to be used for disease diagnosis or particle analyser chips. more

Nanotechnology Day & Everyday Uses of Nanotechnology

October 9 is National Nanotechnology Day in the US, as it’s 10/9 in the American date format (and one nanometre is 10–9 metres). This month’s edition of Periodic Graphics in C&EN takes a look at a selection of the nanotechnology that’s already made its way into our everyday lives. more

The Chemistry of Cold Medicines

Having been struck down by a cold over the past few days, I was reminded of this old edition of Periodic Graphics, which looks at the chemistry of cold medicines. I’m definitely grateful for a number of these right now! more

A Brief Guide to Doping in Sports

The Rio Olympics are underway, and after a build-up that’s already been marred by the Russian doping scandal, officials will be on the look-out for athletes trying to gain an edge by using performance-enhancing drugs. What types of drugs will they be looking for, and why might athletes be t ... more

The Chemistry of Cannabis & Synthetic Cannabinoids

In recent years, there’s been an increase in the number of media reports on users of synthetic cannabinoids. Commonly referred to by names such as ‘Spice’ or ‘K2’, the most recent reported case involved five UK students being hospitalised after use. But what are the chemicals present in ‘sp ... more

World Diabetes Day

Here’s a mini-graphic taking a quick look at what diabetes is, and the differences between the three main types. more
