Responding to your science questions

From why men have nipples to how gravity slingshots work, we put your science questions to our expert panel.

This week, we’re letting you run the airwaves. Victoria Gill puts your science questions to Catherine Heymans, Astronomer Royal for Scotland and Professor of Astrophysics at the University of Edinburgh, Mark Maslin, Professor of Earth System Science at University College London, and Penny Sarchet, Managing editor of New Scientist.

If you’ve ever wondered why men have nipples, how gravity slingshots work, or whether photosynthesis could solve our energy problems, that’s all on this week’s BBC Inside Science.
