Editor's note

With thousands of exoplanets discovered to date, it is no wonder that so many have been classified as “habitable”. This means that they lie at the right distance from a star for liquid water to exist on their surface. While life may be able to survive on such a body if you dumped it there, we have so far been unable to determine whether it could arise there on its own. But now there’s a new method to identify planets with the right conditions for life to evolve. Paul Rimmer talks us through his research.

An orange blow-up balloon, demonstrators with faces painted vibrant orange, nicknames ranging from Agent Orange to Mango Mussolini – the colour of Donald Trump’s face has, perhaps more than anything else, characterised the humour and derision directed at the US president. Trump’s fake tan is certainly funny, but Tania Woloshyn, a historian of tanning, argues that there’s far more to his unnatural hue than meets the eye.

As Brexit day creeps closer, one issue that remains unresolved is the way that food names will be protected in Britain and the EU. This might sound like small fry when a no-deal Brexit is still on the cards. But, as Enrico Bonadio and Marc Mimler explain, the issue of protecting geographical names like champagne and feta will likely play a crucial role in trade negotiations with the EU and beyond.
