  • 906 - World’s oldest forest fossils

    The world’s oldest fossilised forest was uncovered in Somerset last week. We head to palaeobotanist, Dr Christopher Berry’s, lab at Cardiff University to learn about these cladoxylopsids. They lived 390 million years ago and although they are not the ancestors of today’s trees, they reveal some extraordinary evolutionary secrets.

    Also, Marnie speaks to Dr Chris Thorogood of the University of Oxford Botanic Gardens about his new book Pathless Forest: The Quest to Save the World’s Largest Flowers. Called “Rafflesia” plants and found in the remotest parts of South East Asia, their flowers burst from the rain forest floor the size of pumpkins and are critically endangered. Chris talks of his world of extreme fieldwork and hair-raising expeditions, braving leeches, lizards and lethal forest swamps, to discover the rarest of rare blooms.

    Plus, the Wildlife Trust’s Making Friends with Molluscs campaign starts today, and I’m sure many gardeners will declare this an impossible task! We visit some allotments in Bristol to find out how people are managing slug and snail populations. And chat to Brian Eversham from the Trust of Bedfordshire, Cambridgeshire and Northamptonshire, who explains why these garden creatures should be considered our friends, not foes.

    And finally, Dr Stewart Husband from last week’s programme returns to answer more of your burning questions about your tap water.

  • 905 - Human Consciousness: Could a brain in a dish become sentient?

    As the field of neuroscience advances, scientists are increasingly growing brain tissue to study conditions like autism, Alzheimer's and Zika virus. But could it become conscious? And if so, how far away is that scenario?

    Wind, changing water temperatures and salt are all factors known to control ocean currents. But new research suggests there's another element in the mix. When sea monkeys amass, the thousands of swimming legs can create powerful currents that mix hundreds of meters of water.

    Whenever a baby is born, we ask whether it's a girl or a boy. But when it comes to puppies, the question is often about the breed, especially with mongrels. And when we think we know what it is, we make assumptions about how that dog will behave. For instance, if you think there's some golden retriever parentage, you may expect it to be good at playing fetch. But do our perceptions of dog breeds change the way it behaves? That's the question of a new citizen science project called MuttMix, which asks you to guess the ancestry of various mongrels.

    Finally, Charles Dickens is known as one of the best novelists of the Victorian era but a new exhibition is questioning whether he should be also known as a man of science. Dickens campaigned for paediatrics and his powers of description lead to a new conditions being medically recognised. The exhibition will be at the Charles Dickens Museum and it opens in May.

  • 904 - Plastic-eating bacteria, Foam mattresses for crops, The evolved life aquatic, The Double Helix

    A breakthrough for closed loop plastic recycling? Two years ago Japanese scientists discovered a type of bacteria which has evolved to feed on PET plastic - the material from which fizzy drink bottles are made It was isolated at a local recycling centre. An international team has now characterised the structure of the plastic-degrading enzyme and accidentally improved its efficiency. John McGeehan of the University of Portmouth led the team and talks to Adam about where the discovery may lead.

    If you can't recycle plastic, you can re-use. Sheffield University chemist Tony Ryan is working to convert old polyurethane foam mattresses into hydroponic allotment beds so that people at a Syrian refugee camp in Jordan can grow their own crops. Roland Pease reports.

    How southeast Asian sea nomads evolved the life aquatic.

    The Double Helix, fifty years after its 1968 publication. Biologist and historian Matthew Cobb and science writer Angela Saini discuss the place of James Watson's compelling and controversial memoir in the annals of popular science writing. His account of the discovery of the DNA's structure was unlike any science book that had come before. Does it stand the test of time and what of its blantantly sexist treatment of the gifted X-ray crystallographer Rosalind Franklin? Her work was crucial to Crick and Watson's 1953 model of the DNA molecule.

  • 903 - Pesticides in British Farming

    A few weeks ago, Inside Science featured an item on neonicotinoids and the negative impact these pesticides have on insects like honey bees. The discussion turned to alternatives, including organic farming. Many listeners wrote in about some issues that went unchallenged. So this week, Adam returns to the subject to get into the nuts and bolts of both organic and conventional farming.

    Next week sees the launch of a NASA mission called TESS. The Transiting Exoplanet Survey Satellite is surveying the brightest stars near Earth and looking for habitable planets. Roland Pease reports.

    Traditionally, the move from Bronze Age to the Iron Age is estimated to be around 1200 BCE. But recent excavations of smelting sites in Uttar Pradesh in India suggest that this date might be a few centuries late and that it might even originate in Asia. Adam visits The Rutherford Appleton Laboratory in Oxfordshire to see how a particle accelerator is revealing the details of the Indian Iron Age.

    Our ancestors bore a very prominent brow ridge, which scientists think was a symbol of dominance. Modern humans, however, have lost this ridge in favour of a flatter forehead. Why? Dr Penny Spikins and her colleagues think the answer lies in social interaction and in particular, the ability to raise your eyebrows.

  • 902 - Stephen Hawking Tribute

    Adam Rutherford presents a special tribute to the science of Stephen Hawking. He is joined by Fay Dowker, a former PhD student of Hawking and now a professor of theoretical physics at Imperial College, Professor Carlos Frenk, a long-time colleague and friend and fellow physicist and science communicator Professor Brian Cox. They look at the scientific legacy of Stephen Hawking and the role that his work played in bringing us a step closer to a single grand theory that explains how the universe works.
