Ci Newsletter #22: Acne, tomatoes, & alcohol-free beer
After an (unintentional) summer break, the Ci newsletter is back! This issue has the chemistry word on whether to keep your tomatoes in the fridge or not, a look at how alcohol-free beer is made, and an overview of medicines used to treat acne.
Tomatoes: to fridge or not to fridge?
It's tomato season here in the UK, and if you've been growing a glut of your own, you might be wondering where the science stands on whether you should store your tomatoes in the fridge or not. You'll be pleased to hear that chemistry has the answer, as this graphic from the archives explains.
How is alcohol-free beer made?
Alcohol-free beer is of increasingly good quality compared to even a decade ago. But how is it made? This latest graphic looks at the different methods used.
The chemistry of acne treatments
A wonderful flashback to some of the molecules of my teenage years for this month's edition of Periodic Graphics in C&EN. This graphic takes a look at what causes acne in the first place, and some of the medicines prescribed to treat it.

Tomorrow (26 August) is National Dog Day, and if you've ever wondered what causes the smell of wet dog, this graphic has the answer. If you prefer your smells slightly more palatable, on 3 September it's International Bacon Day, and this graphic from the archives takes a look at the compounds that give bacon its aroma.
