Having a fast and easy way to cut out and replace genes could revolutionise areas of biology as diverse as medicine and agriculture. And the discovery of the gene editing tool using CRISPR-cas9 makes that revolution a present reality. But the teams that revealed this gene editing tool piece by piece were not looking for anything to do with genetic engineering: instead they were curious to know more about how bacterial immunity works. Presenter Adam Hart speaks with Professor Jennifer Doudna of t...

Before the eruption of Krakatoa in 1883, nobody knew about the invisible streams of air in the middle atmosphere that are important for air travel and meteorology. Adam Hart explores the archives of the Royal Society in London to reveal a story of how global observations of the atmospheric effects caused by the ejected smoke from Krakatoa unexpectedly revealed the presence of the jet streams. Produced by Rory Galloway. First broadcast on Thursday 26 July 2018.

The coelacanth is a fish that, until 1938, was only known from the fossil record until a young South African curator named Marjorie Courtenay-Latimer found one - only just deceased - on the deck of a fishing boat. Presenter Adam Hart speaks with ichthyologists and curators who knew Marjorie, putting together the story of how a curious mind, determination and a bit of luck saved this 'living fossil' for science.

Evidence for the Big Bang at the start of the universe was discovered by accident, using technology developed to record radio waves from space, that were themselves found by accident. Adam Hart explores serendipity in radio astronomy with Professor Nial Tanvir of Leicester University, and Professor Sarah Bridle of Manchester University, in a story involving not a small amount of pigeon poo, and a persistent odd noise detected from space. Produced by Rory Galloway. First broadcast on Tuesday 24 J...

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 chatrooms 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 the...

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...

The solutions to the problem of plastic pollution and plastic waste lie in many directions. A global plan to stop littering will go a long way. But human behaviour change often needs some economic intervention. One idea by the UK government and many others around the world, is to give a little financial incentive in the form of deposits on plastic bottles, or taxation on single use plastic like coffee cups, food wrapping and plastic bags. Mark Miodownik investigates some of the scientific soluti...

Plastic waste has been a global crisis waiting to happen. To date it's estimated that around 8.3 billion tonnes of waste plastic exists. That's 25 Empire State Buildings or 1 billion elephants. Incredibly around half of this has been generated in just the last 14 years, despite mass production having begun in the 1950s. Events such as China's recent refusal to take any more "foreign rubbish" and Sir David Attenborough's graphic portrayal of the devastation that plastic waste is causing in our oc...

Plastic waste and pollution have become a global problem but is there any sign of a global solution? And how did we allow this to happen in the first place? Across three programmes, materials scientist and broadcaster, Professor Mark Miodownik, explores how we fell in love with plastic, why we've ended up with oceans of waste blighting the environment and what science and society can do about it.

Addiction specialist Sally Marlow examines the science behind addiction to find out why so many people in Britain are hooked on drugs and alcohol. Neuroscientists now have a sophisticated understanding of the networks in the brain that can pull a person towards addiction and hold them there. Changes in the brain also help to explain why it can be so incredibly hard to quit. But brains don't act in isolation, and neuroscience doesn't explain everything. Why do some people get hooked in the first ...

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.

Aged 32, science writer Frank Swain is losing his hearing. Audiologists are concerned there may be a rising tide of 'hidden hearing loss' among young people. As electronic prices have fallen, sound systems have become cheaper and more powerful. At the same time, live music events and personal music players are more popular than ever, resulting in an increase in noise-related hearing damage. In this programme, Frank asks what the future holds for people like him, part of a tech-savvy generation w...

The work of the entomologist very often involves the killing of insects in large numbers. This happens in the search for new species in the exploration of the planet's biodiversity and in ecological investigations to monitor the health of wild insect populations and the impact we are having on the environment. But the methods of entomologists have come under criticism. Last August presenter and entomologist Adam Hart was involved in a citizen science project aimed at surveying the abundance and ...

Animal senses reveal a wealth of information that humans can't access. Birds can see in ultra violet, and some fish can 'feel' electricity. But how do different species sense time? If you've ever tried to swat flies, you'll know that they seem to have super-powered reactions that let them escape before you can blink.

After a long journey, there’s nothing nicer for Katy than climbing into her own bed. It’s often the first major purchase we make when we grow up and leave home. Its significance was not lost on our ancestors. The bed was often the place where societal attitudes to sleep, superstition, sex, and status were played out, sometimes in dramatic form. So where did the bed come from, and what can this everyday object tell us about ourselves? A sleeper in early modern times believed that sleep was akin t...

Have you got one of those wine glasses that can hold an entire bottle of wine? Katy Brand does and she’s even used it for wine - albeit because of a sprained ankle, which would have stopped her from hobbling back and forth to the kitchen for refills. But if we skip back a few hundred years, the wine glass was tiny. Footmen brought their masters what was essentially a shot glass. They quaffed back their wine in one. So how did we go from those dinky little things to the gargantuan goblets we have...

The fork is essential. Even camping without one is a false economy, in Katy’s experience. Even a spork - with a spoon at one end and a fork at the other, with a knife formed along one prong - just won’t do. You need both - a fork to steady the meat and a knife to cut it with. So how did the fork come to be so indispensable? We didn’t always love the fork. Public historian, Greg Jenner, reveals how it was abandoned for the chopstick in Ancient China, and greeted with scorn in Western Europe when ...
