This week (12-18 November) is #RealTimeChem Week! For the unaware, #RealTimChem is a chemistry community on Twitter that encourages chemists to tweet about their chemistry. As in previous years, I put together the banners to promote this year’s event which has the theme #Chem4Life. As part of it, chemists in the community will be celebrating the chemistry you come across every day – so it’s worth checking out even if you’re not a chemist yourself!

Pregnancy has been in the news over the past month, with a royal baby back in October and the usual smattering of celebrity pregnancies. The inspiration for this post, however, originated a little closer to home; let’s just say that, in around 6 months’ time, my wife and I are going to be entering a fun new world of sleep deprivation! Pregnancy brings up a whole host of science and chemistry questions, the first of which is: how do pregnancy tests work?

Autumn is here, and for most of us, it’s a time of beauty as the leaves cascade through an array of hues before pirouetting down from the trees. If you have to travel by train, however, you might tire of ‘leaves on the line’ being the supposed cause of train delays. It turns out to be more than just a flimsy excuse – and particular chemical reactions are partly to blame.

Most plants get nutrients from the soil. But Venus flytraps prey on insects to get what they need. This month’s edition of Periodic Graphics in Chemical & Engineering News looks at how these carnivorous plants molecularly lure and trap their prey. View the full graphic on the C&EN site.
