An underground river of magma and thousands of tremors have been observed across the Reykjanes peninsula in Iceland. We speak to the scientists monitoring the Fagradalsfjall volcano who explain how this might be ushering in a new era of huge volcanic activity in the country. Sir Chris Whitty, Chief Medical Officer for England and Sir Patrick Vallance, former Chief Scientific Adviser to the UK government are due to appear at the Covid-19 Inquiry next week. It’s the next stage of the public inquiry that began proceedings in July last year. Now it’s focussing on the key questions surrounding how science and the scientific community informed government strategy before, during and after the pandemic. BBC Health Reporter Jim Reed has been attending the inquiry and explains what we know from the evidence that’s been given so far – and what to expect next week. David Quammen discusses his book ‘Breathless: The Scientific Race to Defeat a Deadly Virus’. It's a thriller-style narrative revealing how scientists responded to the coronavirus pandemic. It’s our final shortlisted book for the Royal Society Science Book Prize. The winner will be announced next week.
