Guest presented by Liz Bonnin.

As the UK strives to achieve net zero by 2050, nuclear energy is looking more and more likely as a key player in reaching this goal. But it’s not just massive power plants like Hinkley point C - there’s are newer smaller reactors on the scene: small and micro modular reactors. 100 to 1000 times smaller than a conventional reactor, faster to build, and put together entirely in a factory before being shipped out, theoretically, anywhere: are micro modular reactors the future of nuclear energy or too good to be true? Dean of Engineering at the University of Liverpool, Eann Patterson, has just published a paper proposing a fleet of micro modular reactors to bear the burden of our energy load and he joins us to discuss the reality.

What came first, the chicken or the egg? Science writer, broadcaster and now egg expert Jules Howard joins us to answer this age old question. His book Infinite Life tells the story of how the egg propelled evolution – whether it’s bird, insect, or mammal.

This month, scientist Alexandra Freeman’s appointment to the House of Lords was announced. With a background in risk and evidence communication, Alexandra tells us why she applied, what she hopes to achieve, and how the public can get involved.
