Adam Rutherford explores new insights into what lies at the very centre of the Earth. New research from China and the US suggests that the innermost core of our planet, far from being a homogenous iron structure has another, distinct region at its centre. He talks to the study's lead researcher Xiangdong Song and to geophysicist Simon Redfern about what this inner-inner core could tell us about the very long history of the Earth and the long suspected swings in the earth's magnetic field.Professor Andrea Sella, from University College London is a recipient of the Royal Society's Michael Faraday Prize, in recognition, like Faraday himself, of exemplary science communication to the lay public. Andrea gave his prize lecture this week, describing chemistry as one of the 'crowning intellectual achievements of our age'. How justified is the claim? What have chemists ever done for us?The sea forms the basis of ecosystems and industries, and so even subtle changes to the waters could have serious knock on effects. Dr Susan Fitzer from the University of Glasgow has been wading into Scottish lochs to study shelled creatures; they form a vital basis for marine ecosystems and the global food industry. But what effects could ocean acidification have on this vital organism?And to mark Darwin Day Adam Rutherford examines the origins of Creationism and its most recent variation Intelligent Design. Why do opinion polls in the US routinely find that about half of the population denies the truth of Darwin's theory and believes instead that humans were created supernaturally by God at some point within the last few thousand years? He hears from historian Thomas Dixon, and from Eugenie Scott, former director of the National Centre for Science Education - a US organisation committed to keeping evolution (and now climate change) in the US schools' curriculum.Producer: Adrian Washbourne.

As Helen MacDonald's "H is for Hawk" secures 2014's Book of the Year at the Costa Awards, a paper appears describing the hunting tactics of the Northern Goshawk, quite literally, from a birds' eye view. Suzanne Amador Kane of Haverford College in the US describes her work analyzing footage from tiny cameras mounted on the head of the predatory raptor.The Planck Consortium releases yet more findings from the very beginning of the universe. A new age for the very first stars confirms our best models of the universe. But analysis of the dust in our own galaxy edges out the possibility that last year's BICEP2 announcement did in fact represent evidence of inflation and the first observed primordial gravitational waves.And in the last two weeks, two giants of the twentieth century passed away. Science writer Philip Ball shares his thoughts on the lives of Carl Djerassi, father (he preferred mother) of the contraceptive pill, and Charles Townes, known as father of the Laser.Producer Alex Mansfield.

We all remember the floods across much of central and southern England this time last year, and the devastating effect they had on people's lives and livelihoods. Today, a group of researchers at Cardiff University published a report on how people's perception of climate change has evolved in the wake of the floods. To what extent has our belief in man-made climate change altered? Do we now regard last year's events as a sign of things to come? Adam Rutherford talks to Nick Pidgeon from Cardiff University's School of Psychology who led this UK wide studyEarlier this week an international group of climate scientists, geographers and ecologists met at the Stockholm Resilience Centre in Sweden to wrangle how we can practically make the best of the Anthropocene - the new geological epoch that many consider that we now find ourselves in. Gaia Vince author of Adventures in the Anthropocene, reports from the Stockholm meetingAt the UK's Satellite Application Catapult in Harwell, a project has been unveiled that seeks to offer real time data on the world's fishing fleet to help governments police illegal fishing. Pulling together data from shipping registers, satellite images, radar and ships' own transponders, Eyes on the Sea automatically scans for suspicious activity and can alert human users and allow them to see what ships are up to. The Pew Charitable Trusts hope that vessels carrying illegal cargoes can then be tracked across the ocean, and any port receiving them would know where they had been and what they had been up to.How complex cells evolved is a mystery. Current theories on the evolutionary jump, between 1 and 2 billion years ago, from life forms based on a simple prokaryote cell to the complex multiple eukaryote cells with a cell nucleus and a host of complex internal machinery, fails to explain much of what we see within animal, plant and fungi cells today. Adam talks to Buzz Baum a cell biologist at University College London who has devised a new testable model which appears to explain one of biology's most basic questions.Producer: Adrian Washbourne.
