We’ve been rummaging through the Inside Science mailbox to pick out a selection of the intriguing science questions you’ve been sending in, and assembled an expert panel to try to answer them.

Marnie Chesterton is joined by Penny Sarchet, managing editor of New Scientist, Mark Maslin, Professor of Earth System Science at University College London, and Catherine Heymans, Astronomer Royal for Scotland and Professor of Astrophysics at the University of Edinburgh, to get to the bottom of your scientific mysteries.

Why is the moon sterile when the earth is so full of life? Are new organisms going to evolve to eat microplastics? And did Nikola Tesla really find a way of creating free electricity?

Listen in as we try to uncover the answers.
