There is some politics in this week's email. Normally I avoid including political stories. This week, the stories are in because people following @BotanyOne on Twitter are sharing them and because they have some relevance to botany.Next week's issue should be with you around the same time next week, but it might be a bit shorter than usual. I'll be away on holiday for most of the week, and while I think I have the news scanning system working there's a possibility it'll crash once I walk out of the door.Until next week, take care, Alun (webmaster@botany.one)
