Put on some safety goggles as Dr Chris Smith and the Naked Scientist team ignite your bunsen burners with the hottest science news stories, analysis and breakthroughs.

We investigate the rising number of Covid cases across Europe, why’s it happening, and where does the UK stand? Plus, why is NASA on a collision course with an asteroid?

And as we strive for better sustainability, we investigate the strengths of one of our oldest, and most environmentally-friendly building materials… wood!

Scientists turn antibiotics into double edged swords that also activate the immune system to fight superbugs, and should the government turn to Covid Plan B now?

And as the World Health Organisation convenes a new team to investigate the origins of COVID-19, and whether it in fact did come from a lab, we look at why scientists would want to engineer deadly viruses in the first place.

Harry Lewis and the panel tackle the science questions you've been sending in, including whether William Shatner is strictly now an astronaut?
