    Killer robots; Myths and superstitions and conservation; Science book prize nominee - Cordelia Fine; Taxidermy
    Once again, the ethical side of fully autonomous weapons has been raised, this time by over 100 leading robotics experts, including Elon Musk of SpaceX and Tesla, and Mustafa Suleyman of DeepMind. They have sent an open letter to the United Nations urging them to take action in order to prevent the development of "killer robots". The letter says "lethal autonomous" technology is a "Pandora's box", once opened it will be very difficult to close - they have called for a ban on the use of AI in managing weaponry. Gareth asks AI expert, Professor Peter Bentley from University College London, if this is the right approach or is this just an attempt to delay the inevitable? When a paper titled "Fantastic Beasts and Why to Conserve Them" is printed in the journal Oryx, we had to take a closer look. Far more than a publicity stunt, this work by George Holmes, an expert in conservation and society at the University of Leeds, covers an important point. It explores the dangers of neglecting local beliefs, myths and superstitions about the natural world, and animals in particular, when trying to come up with conservation strategies. Cordelia Fine is a professor of the history and philosophy of science at the University of Melbourne. She is the third shortlisted author of the Royal Society Insight Investment Science Book Prize. Her book "Testosterone Rex" explores the science behind gender. She argues that testosterone isn't necessarily the basis for masculinity and that there is so much more to gender than merely our biological sex. 200 years ago, taxidermy was a crucial part of zoological teaching and research, and in the days before BBC wildlife films, often the only way that many people could see strange and exotic wildlife from other lands. Lots of those early specimens are incredibly valuable, and can still be found in museums around the world, although being so old they are often in need of urgent repair. Usually this happens out of sight behind the scenes, but not so at the Grant Museum of Zoology in London, which has been doing its conservation live in the gallery for all to see, to draw attention to the art and science of taxidermy. Some of the more serious repairs get sent to taxidermy conservator Lucie Mascord in Lancashire.Produced by Fiona Roberts Presented by Gareth Mitchell.

    Antarctica's volcanoes, science book prize nominee - Mark O'Connell, US solar eclipse and 40 years of NASA's Voyager mission
    Not so much hiding in plain sight, but tucked under the ice-sheet in Antarctica are 91 volcanoes. This adds to the 47 volcanoes already known on the continent. After a graduate student posed the question,"are there any volcanoes in Western Antarctica?", Dr Robert Bingham, and colleagues, at Edinburgh University, scoured the satellite and database records to find the volcanoes. This huge region is likely to dwarf that of East Africa's volcanic ridge, which is currently the most volcano-dense region on Earth.Journalist Mark O'Connell is the second of our Royal Society Insight Investment Science Book Prize 2017 nominees. His broad-minded, yet sceptical look at the world of 'transhumanism', "To be a Machine: Adventures Among Cyborgs, Utopians, Hackers, and the Futurists Solving the Modest Problem of Death", questions how and why some of us are looking to use technology to fundamentally change the human condition. On Monday 21st of August 2017, some of the United States will go dark. This is the first total solar eclipse, visible from coast to coast in the US for 99 years. Gareth gets excited with veteran eclipse watchers, David Baron and Jackie Beucher.On the 20th of August 1977, NASA's probe Voyager 2 launched. This was quickly followed two weeks later by the launch of Voyager 1 (which was on a faster trajectory). Since then the two spacecraft have been exploring our Solar System, the Heliosphere and interstellar space. Surpassing all expectations, the probes have taught us so much about our planets, their moons and beyond. Gareth looks back at the highlights with the Voyager mission's chief scientist, Professor Ed Stone, in a celebration of the 40 year mission. Produced by Fiona Roberts Presented by Gareth Mitchell.

    European heatwave and climate change, Eugenia Cheng, Next generation batteries for electric cars, Joseph Hooker exhibition.
    The current heat wave in Europe is proving deadly. High day and night temperatures, coupled with high humidity, can be a very dangerous combination. A new study has calculated the risk of deadly heat on a global basis, and shown that between 48% and 74% of the world's population will be subjected to life-threatening heat and humidity for at least 20 days a year. Ed Hawkins, Professor of Climate Science at the University of Reading, discusses the findings. Gareth also asks BBC weatherman, Darren Betts, whether the recent wave of climate trend animations, or gifs, doing the rounds on social media, are a helpful tool in communicating climate change risks.Professor of Mathematics, Eugenia Cheng, is one of the shortlisted authors for the Royal Society Insight Investment Science Book Prize 2017. She talks Gareth through the inspiration for her book "Beyond Infinity: An expedition to the Outer Limits of the Mathematical Universe".The UK Government announced last week that it was aspiring to remove all petrol and diesel vehicles from roads by 2040. Current battery technology relies on lithium-ion batteries. Are lithium, and the other metals required for batteries, sustainable for a totally electric transport system? And do they have the charge capacity to make them a reliable alternative to fossil fuels? Dr Billy Wu, of the Dyson School of Design Engineering at Imperial College London, goes through the alternatives and the next generation of battery technology.To mark the 200th anniversary of the birth of one of Victorian Britain's most important scientists, Joseph Hooker (1817-1911), Kew Royal Botanic Gardens is holding an exhibition titled Joseph Dalton Hooker: Putting plants in their place. It's a fascinating selection of his photographs, journals and paintings. Gareth is taken on a tour by the curators - historian Professor Jim Endersby of the University of Sussex and Galleries and Exhibitions Leader at RBG Kew, Maria Devaney. They explain how as a tireless traveller and plant collector, Hooker was the founder of modern botanical classification and a close friend of Charles Darwin.Produced by Fiona Roberts Presented by Gareth Mitchell.

    Gene-editing human embryos, Spaceman's eyes, Science book prize, Sexual selection in salmon
    Hypertrophic cardiomyopathy is the heart condition that can lead to seemingly super-fit athletes collapsing with heart failure. It affects one in 500 people, and is a heritable disorder. Scientists using the precise gene-editing technique, Crispr CAS 9, have identified one of the genes responsible for the disease and 'fixed' it. This is in very early stage human embryos, prior to implantation. Dr. Fredrik Lanner at the Karolinska institute, is a leader in this field and he describes the work as purely at the experimental stages, but the team have managed to overcome various issues with the technique. Despite the obvious benefits of being an astronaut... exploring new worlds, seeing Earth from space, and of course the glory and fame, it can take a real toll on the body. Astronauts' skeletons and muscles deteriorate in zero gravity, their immune system weakens, and they experience nasal congestion and sleep disturbance. Many symptoms persists once they're back on Earth. But, there's another to add to the list, space flight-associated neuro-ocular syndrome or SANS. Ophthalmologist at Houston Methodist Hospital, Dr Andrew Lee explains that the build-up of fluid in the brain can squeeze the eye and optic nerve and lead to visual disturbance and even vision loss. The shortlist for the Royal Society Insight Investment Science Book Prize 2017 has just been announced. Adam pesters judge Claudia Hammond for the name of the winner (she doesn't tell!) and discusses the criteria for this £25,000 prestigious award. The top 6 books will be featured over the next 6 weeks on BBC Inside Science.Sexual selection - who you decide to have babies with - is usually decided at the dating stage. But the choice does not have to stop at copulation. Post-mating sexual selection is a thing. Mechanisms such as sperm competition, and cryptic female choice, can happen after sex, but before the sperm fertilises the egg. It's not just an internal thing either, it happens in 'external fertilizers', where eggs are laid, and then fertilized by the male sperm outside the female's body, like come fish do in water. Professor Neil Gemmell, at the University of Otago in Dunedin in New Zealand, has been studying just such processes in Chinook salmon. His findings are surprising and could inform us about human reproduction and fertility.Produced by Fiona Roberts.
