Last week, a girl who was born deaf had her hearing restored following gene therapy. In the US, the first commercial gene therapy for sickle cell disease has just begun. And Great Ormond Street Hospital has found great success in their trials and a gene therapy for children lacking an immune system. Gene therapy is clearly having a moment. But how do these groundbreaking therapies actually work? And will they ever be truly accessible to everyone? Geneticist Professor Robin Lovell-Badge answers all. Also this week, atmospheric scientist Laura Wilcox answers an interesting listener question about the effect volcanoes can have on the weather and sticks around to dig into the connection between aerosols and weather in different regions. The exhibition “Bees: A Story of Survival” opened at the World Museum in Liverpool this month. Part of the show explains the how honeybees communicate through vibration. Physicist Martin Bencsik, who collected and studies these vibrations, plays us a few and explains their meaning. And did you get a chance to see the auroras that covered a large part of the Northern Hemisphere last weekend? The intense solar activity that caused them has some people alarm. Jim Al-Khalili, who has written a science fiction novel based on the concept, talks what is protecting us from solar flares and what could go wrong.
