Marnie Chesterton and guests mull over the saga of an AI engineer who believes his chatbot is sentient. Also, climate scientists propose a major leap in earth system modelling, that might cost £250m a year but would bring our predictive power from 100 km to 1km. And the story of a Malaysian Breadfruit species that turns out to be two separate strains - something locals knew all along, but that science had missed. Philp Ball's latest book, The Book of Minds, explores the work still to be done on our conception of what thinking is, and what it might mean in non-human contexts. Beth Singler is a digital ethnographer - an anthropologist who studies societal reaction to technological advancement. They discuss the story this week that a google AI engineer has been suspended on paid leave from his work with an experimental algorithm called LaMDA. He rather startlingly announced his belief that it had attained sentience, publishing some excerpts from interactions he has experienced with it. Prof Dame Julia Slingo this week has published a proposal in Nature Climate Change, co-authored with several of the world's greatest climate scientists, for a multinational investment in the next generation of climate models. Currently, models of the global climate have a resolution of something like 100km, a scale which, they suggest, misses some very fundamental physics of the way rain, clouds and storms can form. Zooming into 1km resolution, and including the smaller physical systems will allow scientist to better predict extreme events, and crucially how water interacts in a real way with rising temperatures in different climes. And can zooming in on taxonomy reveal insights in conservation and biodiversity? Researchers in the US and Malaysia have described a species of breadfruit that has hitherto been considered one species by mainstream science. Locals have long described them as different species, and the genetics proves that view correct. Can more local, granular knowledge help us get a better handle on the conservation status of our planet's biodiversity? Emily Bird Reports.

This week on inside science Marnie Chesterton is looking at how companies measure and account for their use of renewable energy, how politics is impacting science funding in the UK and the technology behind the Queen’s holographic stand in at jubilee celebrations. Dr Anders Bjorn from Concordia university in Montreal talks us through ‘Renewable Energy Certificates’ explaining how they can sometimes be disconnected from real-life reductions in emissions. As he explains in a paper in Nature Climate Change this week, this is a problem, with businesses buying renewable energy certificates that may, even with the best of intentions, mean that corporate estimates of how much they have transferred to renewable energy could be out by as much as two-thirds. For example, in Poland, where much of the grid is powered by fossil fuels, a company can buy RECs from energy producers in Norway, where so much of the grid is de-carbonised and users feel no need to purchase such a certificate. As neg...
Society itself and the ways we live have been transformed in 70 years of science. Marnie Chesterton, Andrea Sella, and Gemma Milne take a tour of the archive to evaluate some of the biggest hits on Inside Science's jubilee list. What did we miss? Presented by Marnie Chesterton.

Why are non-African monkeypox cases causing concern? Also, the first complete human genome from a Pompeiian cadaver, and how YouTube is aiding animal behaviourists. As cases of monkeypox appear strangely dispersed around Europe and elsewhere in the world outside of Africa, BBC health and science correspondent James Gallagher outlines to Vic the symptoms and some of the mysterious elements of this outbreak. In Pompeii, scientists have for the first time managed to sequence the whole genome of an individual killed by the eruption of Vesuvius in 79AD. Serena Viva of the University of Salento describes the site of two individual's tragic demise all that time ago, one female aged around 50 years, and a younger male, both leaning on a couch in a dining room. Geneticist Gabriele Scorrano describes how the ancient DNA (aDNA) was preserved and extracted, and how the male individual's genome was so well preserved it could be sequenced in full. As they suggest this week in Nature, there weren...
Since 2018, Nasa's InSight Mars lander has been sitting on the surface listening to the seismic rumbles of the red planet's deep interior. But this week, plans were announced to finally phase down its activity, as martian dust obscures too much of its solar panels to power it through the forthcoming winter. Jon Amos tells Vic Gill of some of its many successes, and quite why it didn't fly with a duster on board. 50 years of observations across Australia's northern tropical forests suggest yet more bad news for the climate. Trees’ mortality has, it seems, doubled since the 1980s. As Oxford University's David Bauman tells Vic, it seems to be linked to a drying of the air as temperatures rise, and if the trend is also true across the world's other moist tropical forests, they could rapidly slip from being carbon sinks, to carbon sources. Conservationists say we’re losing animal species faster today than at any point in the last 10 million years of Earth’s history. And one approach a...
Astronomers have captured the first image of Sagittarius A*, the gargantuan black hole at the centre of our galaxy. Dr Ziri Younsi, University College London, shares what it took to capture a picture of a supermassive black hole that is 26,000 light-years away and from which (almost) nothing, not even light, can escape. The world’s largest and most powerful particle accelerator, the Large Hadron Collider, is restarting after three years of upgrades. Roland Pease visits the European Particle Physics Laboratory, CERN, to see how things are going, and looks back on some of the team's past successes. Also, how do you investigate the mysterious deaths of the world’s biggest fish when their bodies sink without trace? That’s the quandary facing marine scientists who’ve been trying to figure out what exactly is killing whale sharks. Freya Womersley, UK Marine Biological Association, shares how satellite tracking technology is helping us solve the mystery. And finally, what’s in a name?...
With the cost of living spiralling, many are probably thinking more about the price of food than lithium, titanium, copper or platinum. But the volatility in the global market for these materials - partly because of the pandemic and geopolitical unrest - is causing 'chaos' in the technology supply chain. Elizabeth Ratcliffe, Royal Society of Chemistry, tells Vic that many of us are unwittingly stockpiling these precious metals in our homes, in our old phones and defunct computers, because we don't know what to do with them. Reporter Samara Linton visits N2S, a company in Bury St Edmunds which has found a way to recycle the precious metals and other scarce elements in discarded circuit boards using bacteria. This week more evidence that spring is springing earlier, as Vic heads to what might be the most studied woodland in the world: Wytham Woods in Oxfordshire. Ella Cole, Oxford University, explains how climate change is causing birds to lay eggs three weeks earlier than they did in...
This week, we begin with a disturbing medical mystery. Since the start of the year, almost 200 children worldwide have fallen ill with hepatitis—or liver inflammation—without any apparent cause. Most of the children are under five, and nearly half of the cases were in the UK. Vic Gill asks clinical epidemiologist Deepti Gurdasani, Queen Mary University of London, what we do and don't know about these rare cases. Also on the programme, with a huge tidal range, Wales and the west coast of England have become the focal point for a new generation of tidal power plans. So, is the tidal energy revolution finally happening? Roger Falconer, Emeritus Professor of Water and Environmental Engineering at Cardiff University, and Andrew Scott, CEO of Orbital Marine Power, which has demonstrated a working tidal stream turbine - called O2 - off Orkney, share their insights. And fancy eating an insect burger? Or how about adding seaweed smoothies or mycoprotein meatballs to your diet? Fellow BBC s...
Victoria Gill and guests ask why does scientific communication matters in society and how it might be done better, with Sam Illingworth, Berry Billingsley and Ozmala Ismail. The climate crisis and Covid-19 have shown over the recent years the importance of reliable, relatable, transparent and trusted science communication. But just like science itself, it comes in different forms and takes different approaches. Always keen to keep you up to date, BBC Inside Science takes a moment to discuss good practice and how it might be done better. Dr Oz Ismail is a dementia researcher who also finds time to do stand-up, public engagement and a podcast called Why Aren’t You A Doctor Yet? Sam Illingworth is an Associate Professor at Edinburgh Napier University who investigates science and communication between disciplines. He is also a poet and writer, and has a podcast called The Poetry of Science. And Berry Billingsley is Professor in Science Education at Canterbury Christchurch University. E...
Could magic mushrooms be the key to a revolution in treating depression? Professor David Nutt, director of the Imperial Centre for Psychedelic Research, thinks so. He tells Vic Gill about recent research suggesting that psilocybin - the psychedelic compound found in magic mushrooms - triggers rewiring of the brain in people with treatment-resistant depression. Vic Gill speaks with trial participant Steve Shorney who was diagnosed with depression 30 years ago. Nanobodies. That's the name scientists have given to the tiny antibodies found in the blood of camelids like llamas, alpacas and camels. Reporter Samara Linton heads to Berkshire to meet the llamas whose nanobodies were recently found to neutralise the Covid-19 virus. We hear from Professor Gary Stephens, University of Reading, who is responsible for the llamas' safety and well-being, and Professor James Naismith, director of the Rosalind Franklin Institute which is carrying out the pioneering research with engineered nanobodie...
