Episode 332
For only the second time, the genome of an ancient Denisovan has been sequenced – thanks to the discovery of a 200,000-year-old tooth found in a Siberian cave. This ancient member of the human family has long been a mystery, so this genome is being described as a bombshell moment, revealing an early stage of Denisovan history. We explore how this reshapes our understanding about the origins of our species.
Some 95 per cent of us have a dormant virus, lurking in our bodies – waiting to strike when the moment鈥檚 right. Epstein-Barr virus causes glandular fever – also known as mono or kissing disease – but only in a small number of people. Though new evidence is showing that even dormant viruses may still cause long term health problems.
Formula E electric race cars may have surpassed their fossil fuel counterparts. From greater efficiency to faster acceleration, this is a big turning point for the sport – but they don鈥檛 have the edge on F1 cars in all areas just yet. We find out where they鈥檙e winning and where they鈥檙e falling behind – and how this could translate to better electric road cars for us.
And the legendary science writer Bill Bryson joins the team to discuss the process of revising his bestselling book A Short History of Nearly Everything. He explores some of the most fascinating (and surprising) facts he鈥檚 had to update in the 20 years since the book came out.
