Looking healthy is vital to an attractive appearance. But how do we judge a person's healthiness? We find out how face shape and colour influence our perceptions of health, and revisit the idea of limbal rings: a part of the eye that gives away our health and age.

The Eyes Have It: Limbal Rings and Attraction
What Makes a Healthy Face?

The eye is the window to your... health? The eye on the left has an exaggerated limbal ring. Modified from Joanna Malinowska/freestocks.org

Earlier this year I posted a bonus episode featuring contributions from students in my undergraduate seminar here at Basel University. It proved to be one of the more popular episodes of the podcast. This semester I taught a masters level class on the evolutionary psychology of mate preference and, again, gave the students the task of summarising the research papers they found most interesting for a special bonus episode. As before, most of the students are not native English speakers, nor have they recorded audio before. I am super grateful they agreed to be a part of the podcast (especially after I freaked them out by telling them how many people listened to the previous bonus episode!).

Do Women’s Faces Change Color Over the Menstrual Cycle?

I and my collaborators photographed women multiple times over their cycle and analysed patches of cheek skin for colour changes. Image modified from a photo by Alix Klingenberg.

Stay out of the sun! New research suggests that the skin colour change associated with sun tanning isn't as attractive as the effects of eating carotenoid-rich fruits and vegetables, like tomatoes, pumpkins, and spinach. 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.

Scoff the orange, but scoff it in the shade: new research by Carmen Lefevre shows that the skin colour we get from eating carotenoid rich foods is more attractive than the colour we get from tanning.

Stephen Merchant's stand up act is based on his apparent inability to win over women. But new research by Mary Cowan suggests that people's ideas about what constitutes a GSOH are more flexible than we previously thought. So keep plugging away, Smerch!

New research shows that The Voice's format is right for the wrong reasons: by concealing the contestants from the judges, the judges aren't influenced by appearances, but also, by preventing the contestants from seeing the judges, performances aren't given an unfair boost.

Example images from Stephen's paper that got the Guardian's commenters all flustered. The face in the middle shows the natural skin colour. The faces on the left show the effect of sun tanning, while the faces on the right shows the effect of eating more carotenoids. Participants thought the carotenoid colour looked healthier.
