Can an attractive personality make you appear more attractive? And we find out why when women see red, women see red.

Plus, as a special summer surprise, Hannah Rowland of the Behavioural Ecology and Evolution Podcast interviews Brian Mautz at the ISBE2014 conference about his research on penis size and attractiveness.

This month, we find out how the menstrual cycle influences competition and cooperation and why women’s sexual interest takes a nosedive after childbirth. We also ask the question: what’s the point of cuddling? Does it make us feel closer to our partner, or is it just a stepping stone to sex?
