Can we Control the Dark Side of the Internet? The Internet is the world's most widely used communications tool. It’s a fast and efficient way of delivering information. However it is also quite dumb, neutral, treating equally all the data it passes around the world. From data that forms scientific research papers, the wealth of social media to keep us all connected with friends and relatives, entertainment or material we would rather not see- from political propaganda to horrific violence, the I...

With the coming of the World Wide Web in the 1990s internet access opened up to everybody, it was no longer the preserve of academics and computer hobbyists. Already prior to the Web, the burgeoning internet user groups and chat rooms had tested what was acceptable behaviour online, but access was still limited. Aleks Krotoski asks whether the Web through enabling much wider use of the internet is the villain of the piece in facilitating not just entertainment and commerce, but all aspects of th...

Just how did the Internet become the most powerful communications medium on the planet, and why does it seem to be an uncontrollable medium for good and bad? With no cross border regulation the internet can act as an incredible force for connecting people and supporting human rights and yet at the same time convey the most offensive material imaginable. It has become the most useful research tool on earth but also the most effective way of delivering threats to the security of governments, the h...

Silicon is literally everywhere in both the natural and built environment, from the dominance of silicate rocks in the earth crust, to ubiquitous sand in building materials and as the basis for glass. We've also harnessed silicon's properties as a semiconductor to build the modern electronics industry - without silicon personal computers and smartphones would simply not exist. Silicon is also found widely across the universe. It is formed in stars, particularly when they explode. And the similar...

Carbon is widely considered to be the key element in forming life. It's at the centre of DNA, and the molecules upon which all living things rely. Monica Grady, Professor of Planetary Science at the Open University, explores the nature of carbon, from its formation in distant stars to its uses and abuses here on earth. She looks at why it forms the scaffold upon which living organisms are built, and how the mechanisms involved have helped inform the development of new carbon based technology, an...

From the origins of the universe, though batteries, glass and grease to influencing the working of our brains, neuroscientist Sophie Scott tracks the incredible power of lithium. It's 200 years ago this year that lithium was first isolated and named, but this, the lightest of all metals, had been used as a drug for centuries before. From the industrial revolution it proves its worth as a key ingredient in glass and grease, and as the major component in lithium ion batteries it powers every smart...

Oxygen appeared on Earth over two billion years ago and life took off. Now it makes up just over a fifth of the air. Trevor Cox, professor of acoustic engineering at the University of Salford, England, tells the story of oxygen on Earth and in space. Without oxygen, there would be no life on Earth, yet it was not discovered until late in the 18th Century. During the Great Oxidation Event, three billion years ago, cyanobacteria, thought to be the earliest forms of life on our planet, started to p...

The most beautiful and shimmering of the elements, the weirdest, and yet the most reviled. Chemist Andrea Sella tell the story of Mercury, explaining the significance of this element not just for chemistry, but also the development of modern civilisation. It's been a a source of wonder for thousands of years - why is this metal a liquid? and what is its contribution to art, from the Stone Age to the Renaissance? We look at how Mercury is integral to hundreds of years of scientific discoveries, f...

For more than 65 years we have known that smoking kills. So how can it be that a Mexican wave of tobacco use, disease and death is heading at breakneck speed towards the world’s poorest people? Millions will die of lung cancer and it is hard to grasp that this is a largely preventable disease. Uruguay in South America could hold the key to breaking this wave. Under a President who is a cancer specialist they introduced some of the most radical tobacco control policies in the world and attracted ...

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.

Robots are becoming present in our lives, as companions, carers and as workers. Adam Rutherford explores our relationship with these machines. Have we made them to be merely more dextrous versions of us? Why do we want to make replicas of ourselves? Should we be worried that they could replace us at work? Is it a good idea that robots are becoming carers for the elderly? Adam Rutherford meets some of the latest robots and their researchers and explores how the current reality has been influenced...

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...

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 wou...

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...

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 Sou...

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 ...
