Dr Chris Smith and the Naked Scientist team present the latest science news, analysis and breakthroughs.

In this week's episode... we discuss a future proof Covid jab that combats variants that don’t even exist yet, signs that antimatter does obey the rules of gravity and why one doomsday scenario is predicting we’re all going to wiped out in 250 million years’ time when plate tectonics give us a new super continent.
