It’s time for an unexpected celebration and we look to science for advice on clothes, cake and how presenter Marnie and panellists Christine and Candice can improve their singing. We also hear about the sleuths who have tracked down an animal that’s been presumed extinct for almost a century, we help a listener find the answer to whether using sunscreen is stopping him from getting vitamin d and Marnie talks to the Dog Aging Project to ask why studying healthy ageing in our canine companions can lead to better health for people too.

Presenter: Marnie Chesterton
Panellists: Christine Yohannes and Candice Bailey
Guests: Bryan Nichols, Pennsylvania State University and Matt Kaberline, founder of the Dog Aging Project.
