This month, I find out that penguins can’t tell the difference between savoury and sweet. I also chat with Sonia Van Wijk from The Université de Sherbrooke in Quebec, Canada, about what makes a male tree swallow attractive to a female who's on the look-out for more than one partner. And in the Scientific spark, I talk to social network whizz Damien Farine, from the University of Oxford, about his path into science.
