Neanderthals; Plague; Wind Tunnel; Music Timing; Stem Cells

We now know that Neanderthals and our ancestors interbred over 40,000 years ago. Recent research has shown that most people of European or East Asian descent carry a small percentage of Neanderthal DNA - about 2%. But two new papers this week examine some of the physical characteristics we may have got from the genes of our ancient cousins. They include some disease susceptibilities and hair and skin characteristics, which may have helped our forebears survive in northern climes.

There have been many sensationalist headlines in the news this week suggesting that the deadly bubonic plague could return, when really, it never went away. And while it can still be deadly, it can be treated early with antibiotics. In the Middle Ages the Black Death is thought to have killed up to half of the European population and so too did the Justinian Plague 800 years earlier. Now scientists have compared these two plague genomes to find that they were both caused by distinct strains of the same bacterium, Yersinia Pestis. Knowing how the pathogen evolved in the past is crucial to our understanding of possible future strains of plague. Lead author Dr David Wagner from the University of Arizona tells Dr Adam Rutherford that it's very unlikely the plague will return on a mass scale.

It's a windy Show Us Your Instrument this week - Prof Konstantinos ('Kostas') Kontis, Professor of Aerospace Engineering shows us around his wind tunnel. It's used to help develop more effective plane wings, helicopter rotors, and wind turbine blades, but cyclist Sir Chris Hoy has also been a test sample. Glasgow University is currently building a hypersonic wind tunnel, which can test air flow at speeds of up to Mach 10.

We all unconsciously synchronise our movements and researchers at the University of Birmingham have shown how professional musicians make tiny adjustments in their playing to keep time with their colleagues. Alan Wing, Professor of Human Movement in Psychology tells Adam how this research about minute synchronisation is helping to inform how robots can be designed to interact with humans.

Stem cells can become any other cell in the body from nerve to bone to skin, and they are touted as the future of medicine. Embryos are one, often ethically charged, source of stem cells and in 2006 Nobel prize winning research showed that skin cells could be "genetically reprogrammed" to become stem cells. These were called induced pluripotent stem cells. Scientists in Japan have now shown, in mice, that this previous painstaking method of making the versatile cells can be replaced by little more than a short dip in acid. Professor Chris Mason from University College London tells Adam that this major breakthrough could be faster, cheaper and possibly safer than other cell reprogramming technologies.

Biotech Risks and Asteroid Anxiety

Biotech Risks and Asteroid Anxiety

Scientists gather this week to tackle emerging risks from cutting-edge biotech, echoing the landmark Asilomar conference that shaped genetic engineering safety 50 years ago. What new threats face us, and how can the scientific community stay ahead of them?Also in the programme: are you feeling asteroid anxiety? We take a closer look at the chances that ‘2024 YR4’ will hit us... We get the latest calculations on this space rock's potential collision course with Earth in 2032.And, as members of the Royal Society debate whether to expel Elon Musk from their ranks, we explore past fellows who rattled the establishment. Fellows meet next month to decide his fate.If you want to find out more about the history of genetic engineering - from the Asilomar conference to the present day - search for Matthew Cobb's series 'Genetic Dreams, Genetic Nightmares' on BBC Sounds.

US science in chaos

US science in chaos

The United States is the world’s science superpower. But right now, much of its research community is in a state of confusion.In the past few weeks, the Trump administration has issued a huge number of orders – amongst them, large funding cuts for scientific institutions. We unpick what the implications are for the country’s role on the global scientific stage.Also in the programme, we take another look at phone bans in schools. Why are the results of a recent study so different to the personal experience of teachers and students?And Britain has a new snake – and it’s apparently thriving. Where has it come from and should we be worried?To discover more fascinating science content, head to bbc.co.uk search for BBC Inside Science and follow the links to The Open University.

The World’s Biggest Iceberg

The World’s Biggest Iceberg

It’s the biggest story of recent weeks. Literally. Trillion-tonne iceberg A23a is on the move. But where is it headed and why – and what might it mean for the scientists and penguins in its path? And from a giant ‘megaberg’ to a giant pile of highly radioactive material, we find out what locking away a load of radioactive waste has in common with baking a cake. And we’re joined by science journalist Caroline Steel to guide us through this week’s science news. We’ll hear about the first study into whether banning phones in schools works, why scratching an itch might have benefits beyond just satisfaction, and the perfect formula to boil an egg... Presenter: Victoria Gill Producers: Sophie Ormiston, Ilan Goodman & Gerry Holt Editor: Martin Smith Production Co-ordinators: Jana Bennett-Holesworth & Josie HardyScience-backed boiled egg recipe:- You need two pans… and exactly 32 minutes - Keep one pan at 100 degrees Celsius (boiling) and the other pan at 30 degrees Celsius - Move the egg between the two every two minutes for 32 minutesEnjoy!To discover more fascinating science content, head to bbc.co.uk search for BBC Inside Science and follow the links to The Open University.

Is 1.5 still alive?

Is 1.5 still alive?

1.5C. It’s THE number we talk about when we talk about climate change. But what does 1.5C actually mean now – and as the world saw record-breaking heat last year, does it even matter anymore? Climate scientist Mark Maslin and environmental psychologist Lorraine Whitmarsh discuss. Also this week, new clues about how life may have begun from a dusty space rock called Bennu, and New Scientist’s Graham Lawton brings us the science of the week, including AI’s ‘Sputnik moment’, the mice born with two fathers, and how often do unexpected discoveries happen?

Next-gen batteries and 'dark oxygen'

Next-gen batteries and 'dark oxygen'

Following a devastating fire at the world’s largest lithium-ion battery plant, Inside Science probes the present and future of a technology we rely on every day. Lithium-ion batteries were a technological breakthrough, powering everything from mobile phones to electric vehicles, but as funding is poured into researching alternatives, are we on the verge of something safer, faster, and more efficient?Also this week, we learn about the “dark oxygen” potentially being produced in the deep ocean and friend of Inside Science, Anjana Ahuja, brings us her favourite science stories of the week, including a new material described as ‘chainmail on steroids’ and contagious urination.Presenter: Marnie Chesterton Producers: Ella Hubber, Sophie Ormiston & Gerry Holt Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth To discover more fascinating science content, head to bbc.co.uk search for BBC Inside Science and follow the links to The Open University.
