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

As a small rocky planet, Mars is similar in many respects to the Earth and for that reason, many have thought it may harbour some kind of life. A hundred years ago, there was serious talk about the possibility of advanced civilisations there. Even in early 1970s, scientists mused that plant-like aliens might grow in the Martian soil. The best hope now is for something microbial. But the discovery that even simple life survives there or did some time in its history would be a profound one. We would know that life is not something special to Earth.NASA’s Curiosity rover has discovered that 3.7 billion years ago, there were conditions hospitable to life on Mars – a sustained period of time with lakes and rivers of water. The earlier rover Spirit found deposits of silica from ancient hot springs which some planetary scientists argue bear the hallmarks of being shaped by microbes - possibly. The next five years may dramatically advance the hunt for life on Mars. In 2020 the European and Russian space agencies will

In Lifechangers, Kevin Fong talks to people about their lives in science.Major General Charles Bolden – a former NASA administrator – talks to Kevin Fong about his extraordinary life, from childhood in racially segregated South Carolina to the first African American to command a space shuttle. He had originally hoped to join the Navy, but was unable to as an African American. Although Charles refused to take no for an answer and after much petitioning he was accepted. From there he reached for the stars.Image: Charlie Bolden, © Alex Wong/Getty Images

In Lifechangers, Kevin Fong talks to people about their lives in science.Astrophysicist and Director of the Hayden Planetarium in New York City, Neil deGrasse Tyson is well known in the US since he presented the TV series Cosmos: a spacetime odyssey. He talks to Kevin Fong about growing up in Brooklyn, becoming obsessed with the night sky and how he became a broadcaster and writer.Image: Neil deGrasse Tyson, © Cindy Ord/Getty Images for FOX

In the start of a new series of Lifechangers, Kevin Fong talks to three people about their lives in science.His first conversation is with a man better known for his life in science fiction, George Takei, the Japanese American actor who played Sulu in the TV series, Star Trek. They discuss the voyages of the Starship Enterprise and the ideas of other worlds featured in Star Trek. He talks about his own epic life journey – how his family was imprisoned when the US joined the Second World War and his campaigning against social injustice.Photo: George Takei making the Live Long and Prosper symbol, © Suhaimi Abdullah/Getty Images

Bees pollinate and can detect bombs and compose music. What would we do without them? The world owes a debt of gratitude to this hard working but under-appreciated insect. One third of the food we eat would not be available without bees, meaning our lives would be unimaginably different without them.Bee populations are dropping by up to 80% in some countries and the consequences are potentially catastrophic. The use of neonics pesticides in farming has been one of the main causes in the decline in bee numbers and now the farming world is having to take drastic action to try and reverse the trend. The situation has become so dire in some parts of China that the government set up a scheme in which humans had to pollinate plants by hand. Researchers in America have been so worried about a world without bees that they have started to develop robotic 'insects' to emulate their work. What’s causing the drop in populations and what might save them? Dr George McGavin hears from scientists and researchers in Africa

Since the birth of Louise Brown - the world’s first IVF baby - in England in 1978, many children have been born through in vitro fertilisation. IVF doesn’t work for everyone but over the last few decades basic research into human reproduction has brought about huge improvements. In the UK the Human Fertilisation and Embryology Act, passed in 1990, made it illegal for research on human embryos to be permitted beyond 14 days. In a dozen other countries, from Canada and Australia to Iceland and South Korea the 14 day limit is enshrined in law and in five others, including China, India and the US, there are guidelines that recommend that limit. Just recently researchers at Cambridge University have kept embryos alive in the lab for 13 days. They and others are calling for the limit to be extended for another one or two weeks, so they can study why early pregnancies fail. Matthew Hill reports on the issues raised by these new developments in embryo research.Image: Light micrograph of fertilized human egg cell © S

As the pace of technology moves at ever greater speeds, how vulnerable are we when making split second decisions? Kevin Fong flies with the Helicopter Emergency Medical Service, making split-second, life-or-death decisions. He examines how we can come to terms with the growing challenge of quick and accurate front line decision making.Picture: Presenter, Kevin Fong in air ambulance, Credit: BBC

Ever wished you could miss an entire cold dark winter like bears or dormice? Kevin Fong explores the possibilities than humans could hibernate. This ability could help us recover from serious injury or make long space flights pass in a flash.The first report on human hibernation in a medical journal was in the BMJ in 1900. It was an account of Russian peasants who, the author claimed, were able to hibernate. Existing in a state approaching "chronic famine", residents of the north-eastern Pskov region would retreat indoors at the first sign of snow, and there gather around the stove and fall into a deep slumber they called "lotska". No-one has ever found these peasants but there is serious research into putting humans into suspended animation, for long distance space travel or for allowing the body to recover from major injury.The greatest clues into how to pull off hibernation comes from the American Black Bear. Dr Kevin Fong, an expert in trauma medicine, talks to Dr Brian Barnes, Director of the Institute o

Internet shopping continues to rise worldwide. That means a lot more delivery vans on the streets of our towns and cities. Those vans and trucks, often powered by dirty diesel engines, are contributing to air pollution problems that can cause significant increases in premature death and great discomfort for people suffering from heart and lung conditions.As part of the BBC’s So I Can Breathe season Tom Heap sets out to find innovative solutions. Could drones or robots be the answer? Could we cut out the middle man and use 3D printers to create everything we want at home? Perhaps it is simply a matter of converting all those vans to electric or gas power or even carrying out the majority of home deliveries by bike. With the promise of ever-quicker delivery times the search for a solution becomes ever more urgent if we are to prevent our consumer addiction becoming an air pollution crisis on every doorstep.(Photo: Tom Heap.

Frank Swain can hear Wi-Fi.Diagnosed with early deafness aged 25, Frank decided to turn his misfortune to his advantage by modifying his hearing aids to create a new sense. He documented the start of his journey three years ago on Radio 4 in 'Hack My Hearing'.Since then, Frank has worked with sound artist Daniel Jones to detect and sonify Wi-Fi connections around him. He joins a community around the world who are extending their experience beyond human limitations.In 'Meet the Cyborgs' Frank sets out to meet other people who are hacking their bodies. Neil Harbisson and Moon Rebus run The Cyborg Foundation in Barcelona, which welcomes like-minded body hackers from around the world. Their goal is not just to use or wear technology, but to re-engineer their bodies.Frank meets the creators of Cyborg Nest, a company promising to make anyone a cyborg. They have recently launched their first product - The North Sense - a computer chip anchored to body piercings in the chest, which vibrates when it faces north.But it

Two challenges for the team today involving singing and navigating. The Melodic Mystery "Why is my mother tone deaf?" asks listener Simon, "and can I do anything to ensure my son can at least carry a tune?" Hannah admits to struggling to hold a tune and has a singing lesson with teacher Michael Bonshor, although it doesn’t go quite to plan. We meet Martin who hates music because he has the clinical form of tone deafness, known as amusia. Just as people with dyslexia see words differently to other people, if you have amusia you don't hear melodies in the same way. Adam talks to music psychologist Dr Vicky Williamson from Sheffield University who studies Martin, and others like him, to try and discover why their brains operate differently.The Lost Producer In our second case, we investigate why some people have a terrible sense of direction. It’s the turn of Producer Michelle to be put to the test to try improve her poor navigational skills. Prof Hugo Spiers from University College London examines Michelle’

Neal Shepperson asks, "What determines left or right handedness and why are us lefties in the minority?"One in ten people are left-handed, but where does this ratio come from and when did it appear in our evolutionary past?Hannah talks to primatologist Prof Linda Marchant from Miami University about why Neanderthal teeth could hold the answer.Prof Chris McManus from University College London tells Adam about his quest to track down the genes responsible for whether we're right or left handed.But does left-handedness affect people’s brains and behaviour? Some researchers point to a link between left-handedness and impairments like autism or dyslexia. Others claim that lefties are more creative and artistic. So where does the answer lie? The team consults Professors Sophie Scott, Chris McManus and Dorothy Bishop to find out the truth about left-handers.If you have any Curious Cases for the team to investigate please email curiouscases@bbc.co.ukPicture: Left handed child, credit: Diarmid Courreges/AFP/Getty Imag

Listener Paul Don asks: "I'm wondering what's the feasibility of terraforming another planet ie Mars and if it is possible to do the same thing with something like the moon? Or, why isn't there already a moon-base? Surely that is easier."Dr Adam Rutherford and Dr Hannah Fry consider moving to another planet, and discover what challenges they would need to overcome to live in space. They consult engineer Prof Danielle George from the University of Manchester and Dr Louisa Preston, UK Space Agency Aurora Research Fellow in Astrobiology. Adam also hears about attempts to recreate a Martian base on a volcano in Hawaii. He calls Hi-Seas crew member Tristan Bassingthwaighte, who has just emerged from a year of isolation.The Bad Moon Rising “A teacher I work with swears that around the time of the full moon kids are rowdier in the classroom, and more marital disharmony in the community," says Jeff Boone from El Paso in Texas. “Is there any biological reason why the moon's phases could affect human moods and behaviou

Two cases today for Drs Adam Rutherford & Hannah Fry to investigate, involving strength and weight.The Portly Problem"Why do we have middle aged spread?" asks Bart Janssen from New Zealand. In this episode we ponder the science of fat, from obese mice to big bottoms.Why do we put on weight in middle age? And are some types of fat better than others? Hannah meets Prof Steve Bloom at Imperial College, London to discuss why pears are better than apples when it comes to body shape.And Adam talks to Dr Aaron Cypess from the National Institutes of Health in Maryland, who has created a 'fatlas' - an atlas that maps fat inside the body. The Strongest Substance"What is the strongest substance in the universe?” asks Françoise Michel. “Some people say it is spider web, because it is stronger than steel. Is it iron? Is it flint? Is it diamond because diamond can be only be cut by diamond?" Adam and Hannah put a variety of materials, from biscuits to toffees, under the hammer to test their strength. In their quest to

"Is there any such thing as nothing?" This question from Bill Keck sparked a lot of head scratching. Dr Adam Rutherford and Dr Hannah Fry first consider the philosophy and physics of nothing. As Prof Frank Close, author of Nothing: A Very Short Introduction explains, nothing has intrigued great thinkers for thousands of years, from the Ancient Greeks to today's particle physicists. Otto Von Geuricke, the Mayor of Magdeburg in Germany, invented the artificial vacuum pump in the 17th Century and presented spectacular displays to demonstrate the awesome power of nothing. Cosmologist Andrew Pontzen helps Hannah search for nothing in the depths of space and inside the atom. However, as they find out, recent discoveries in subatomic physics have proved that nothing is impossible.Undeterred, the team continue the hunt for nothing by turning to mathematics. The story of zero is fraught with inspiration, competition and controversy. Banned in Florence and hated by the Church, zero had a rocky road to acceptance after

There's a new light of hope in the Middle East. It's a scientific experiment called SESAME - intended to do world-class science and bring together researchers from divided nations. Its members include Palestine and Israel, Pakistan and Iran, Jordan, Egypt, and more. First conceived in the late 1990s, it has just seen the first spark of electricity flow through its high-vacuum steel pipes, last week, and first science should follow soon. The BBC’s Roland Pease paid his second visit to the SESAME campus just as the final pieces were being put in place, and met some of the key players, and heard their hopes.Picture: Sesame with presenter Roland Pease and Herman Winnick, copyright Noemi Caraban

The incoming administration of President Trump has frightened many in the international environmental community. The result of US election in November was announced during the 2016 Marrakech UN Climate Change Conference, a meeting where most delegates were working to deliver on the promises of the previous Paris accord. Instead, a new US direction seemed to have emerged, with some in the new US cabinet going so far as to suggest the US should withdraw altogether from Paris, scrap the US’s own Clean Power act, and re-open coal mines. Roger Harrabin explores whether the Climate Deal is dead, and whether the EU and other countries, such as China and India, might follow the Trump suit and relax their low-carbon initiatives.Image: Republican presidential nominee Donald Trump holds a sign supporting coal during a rally at Mohegan Sun Arena in Wilkes-Barre, Pennsylvania on October 10, 2016, credit: Dominick Reuter/AFP/Getty Images
