First stars, Life on Mars, Climate update, Control of CRISPR, Jamestown forensic genetics
Adam Rutherford and guests discuss 2018 in space, climate science and genetics and listeners' questions. Dr Emma Chapman of Imperial College chooses the discovery by the EDGES telescope of the first stars as her highlight of the year and answers a question from Evgeniy Osievskyi about searching for life on Mars in lava tubes. Dr Tamsin Edwards of Kings College London talks about the international approach to keeping global warming below 1.5 degrees and explains the processes going on in the ocean when it absorbs carbon dioxide in response to a query from Derek McComiskey. Pete Stokes asks if the scientific community could come up with a global and hopefully binding agreement to control CRISPR gene editing on humans. Adam and Professor Turi King of Leicester University discuss this possibility. Looking back at 2018 Turi picks the role of forensic genetics in finding the Golden State killer in the US. Looking ahead to 2019, Emma is hoping for more insights into the very early universe and into dark matter and dark energy, Tamsin is getting ready to research the role of ice sheets in sea level rise and Turi is applying genetic genealogy to find out if a skeleton found at Jamestown, the first permanent British colony in America, is really that of the Governor of Virginia, Sir George Yeardley.

BBC Inside Science > Gene-edited twins, Placenta organoids in a dish, When the last leaves drop

Claims by a Chinese scientist that he has gene-edited human embryos, transplanted them producing genetically edited twins, who will pass on these changes to their offspring, has the scientific community outraged. The work, which was carried out in secret, has not been officially published or peer reviewed, but if the claims are to be taken seriously, this work severely flaunts international ethical guidelines at many levels...

BBC Inside Science > Fish Farming and Climate Change, Gigantic Fungus, Robot Swarms, Gaming in Schools, Drones

Wester Ross Fisheries says over half the salmon at one of its sites have been wiped out because of high seawater temperatures. This highlights yet another damaging effect of climate change, at a time when aquaculture is playing an ever-greater role in feeding us all. Professor of Food Security at the University of Stirling, Rachel Norman, discusses the challenges of farming fish in the age of climate change with Gareth Mitchell...
