Boaty McBoatface in Antarctica, Aeroplane biofuels, Bakhshali manuscript, Goldilocks zones
The submarine famously named Boaty McBoatface is deployed this week for its first mission to examine a narrow submarine gap in the South Atlantic. Mike Meredith of the British Antarctic Survey tells Adam Rutherford how this research into the behaviour of deep water at this crucial point in the oceans will help us answer key questions about global ocean temperature flows.Some close-quarter flying in the wake of a jet has provided new insights on reducing aircraft pollution. Richard Moore at NASA Langley in Virginia describes how he's taken to the skies to measure gasses emitted by new biofuels to assess their impact in reducing carbon soot particles, aircraft contrails and climate-changing cloud formations across the skyAngela Saini visits the Bodleian Library in Oxford where the Bakhshali manuscript which contains possibly the very first graphical representation of the number zero is finally being carbon dated so we can better understand its scientific importanceAnd the habitable zones around stars in our the universe just got a whole lot bigger. Lisa Kaltenegger of the Carl Sagan Institute reveals how the presence of volcanoes pumping out hydrogen has a significant warming effect on planets, and increases the range of the so called Goldilocks Zone Producer: Adrian Washbourne.

Rise of the Robots: 3. Where is my mind?
From Skynet and the Terminator franchise, through Wargames and Ava in Ex Machina, artificial intelligences pervade our cinematic experiences. But AIs are already in the real world, answering our questions on our phones and making diagnoses about our health. Adam Rutherford asks if we are ready for AI, when fiction becomes reality, and we create thinking machines.

Rise of the Robots: 1. The history of things to come
The idea of robots goes back to the Ancient Greeks. In myths Hephaestus, the god of fire, created robots to assist in his workshop. In the medieval period the wealthy showed off their automata. In France in the 15th century a Duke of Burgundy had his chateau filled with automata that played practical tricks on his guests, such as spraying water at them. By the 18th century craftsmen were making life like performing robots. In 1738 in Paris people queued to see the amazing flute playing automaton, designed and built by Jacques Vaucanson.With the industrial revolution the idea of automata became intertwined with that of human workers. The word robot first appears in a 1921 play, Rossum's Universal Robots, by Czech author Carel Chapek.Drawing on examples from fact and fiction, Adam Rutherford explores the role of robots in past societies and discovers they were nearly always made in our image, and inspired both fear and wonder in their audiences. He talks to Dr Elly Truitt of Bryn Mawr College in the US about ancient and medieval robots, to Simon Shaffer, Professor of History of Science at Cambridge University and to Dr Andrew Nahum of the Science Museum about !8th century automata, and to Dr Ben Russell of the Science Museum about robots and workers in the 20th century. And Matthew Sweet provides the cultural context. Show less

Earth's Earliest Life, The Benefits of Pollution, Sexuality and Science and New ideas on Evolution
The World's oldest sedimentary rocks reveal traces of our earliest ancestors. New analysis shows life forms existed more than 3.7 billion years ago which were very similar to those found in our deepest oceans today, microbial life around hydro thermal vents. Some pollution might be good for the world oceans. New finding from China show how iron oxide pollution from power generation and industry has been turned into a source of nutrients for phytoplankton - by interacting with other chemical pollutants. The researchers say this is increasing the ability of the ocean to lock up atmospheric carbon dioxide and so reduce the impact of man made greenhouse gasses. They query whether reducing this kind of pollution could have a negative impact. This week The Royal Society celebrated LGBT history month and 50 years since the partial decriminalisation of homosexuality in England and Wales Rory Galloway meets Sir Dermot Turing, the nephew of renowned computer scientist Alan Turing, to discuss Alan’s Legacy for LGBT scientists today, and we look at the continued impacted of homophobia in science. And we hear about a new test for ideas in Evolution. This involves recreating the ancestors of fruit flies. The findings have overturned an established theory on genetic inheritance in these alcohol tolerant flies.

The perils of fake science news, The neanderthal inside us, What The Beatles really sang - statistically speaking
A woolly story about resurrecting mammoths raises serious questions for medical ethics. News of a scientist's plan to resurrect mammoths has spread around the world. However the story is largely untrue. We look at how this kind of 'fake science news' story can impact on perceptions of real medical research - some times with negative consequences. Almost all Europeans and Asians carry Neanderthal genes. Until recently these were thought to have little impact on us today, but new research shows they may be involved with determining height and aspects of both our physical and mental health. And what were Lennon and McCartney really thinking when they wrote their hit songs? Thanks to the number crunching power of computer algorithms the emotional content of 23 years worth of their compositions have been analysed. The results are both startling and for Beatles fans perhaps a little unsurprising.

Science and cyber security, Dinosaur babies, Winston Churchill and level crossings
Testing cyber security with science. The UK now has a new National Cyber Security Centre. However there is very little scientific evidence against which to test the detection of cyber attacks and effectiveness of measures to prevent them. We ask what is needed to turn cyber security into a more scientific discipline.Winston Churchill and Aliens. Throughout his life Churchill maintained a strong interest in scientific developments and wrote widely on subjects from quantum mechanics to nuclear energy. Newly discovered papers show he also had an interest in the potential for life on other planets.Dinosaurs and egg laying. A new fossil find revealing a dinosaur with an unborn baby suggests live births may have occurred many years earlier than previously thought. Turn off at level crossings. New research suggests personal messages about the impact of engine fumes on health may be the most effective way of persuading drivers to switch off their engines at level crossings.
