How much of a risk is space junk?

The Ealing Beaver Project has found success as two new beaver kits have been born in a park in London after being reintroduced last October. Marnie visits the site to learn more about the benefits they bring - but beavers are just a drop in the river of urban rewilding. We find out what the practicalities and pitfalls of letting nature take back space in our cities are.Do you feel like your dog is watching you? You're probably right. Zoologist and broadcaster Jules Howard ponders on the human-watching acuity of our beloved pets.And our guts are not the only places where bacterial communities thrive, new research tells us that our microwaves also have a microbiome. Should we be worried?Presenter: Marnie Chesterton Producers: Ella Hubber, Sophie Ormiston and Gerry Holt Editor: Martin Smith Production Co-ordinators: Jana Bennett-Holesworth and Andrew Rhys Lewis

Today we will be going for gold in more ways than one. Inga Doak, the Head of Sustainability at The Royal Mint, reveals how the company plan to ‘urban mine’ gold from household electronic waste and turn it into jewellery. But with tens of millions of tonnes of e-waste piling up every year, the environment policy adviser at the Royal Society of Chemistry, Izzi Monk unpacks how the UK can clean up its act. Vic puts her stable boots on to visit some very pampered thoroughbred foals to find out what their poo can reveal about their future success on the racecourse. From horses to humanity, sports geneticist Alun Williams discusses how our genetic make-up could determine whether or not we are destined for gold at the Olympics. Plus, Roland Pease channels his inner child to investigate his youthful obsession with Mars as NASA looks for new microbial life on the red planet.

Space junk. It might sound like an out-of-this-world problem that we don’t need to worry about here on Earth – but is it? As we send more and more metal in the form of satellites up into space, scientists are warning it is becoming more of a risk both here – and up there. We dig into the problem and what’s being done to clean it up. Also this week, we answer a listener question about oceans and their influence on global temperatures, and we ponder the use – and sometimes abuse – of scientific language. And with the Paris Olympics well under way, how much does sex affect sporting performance?

CERN’s plans to build a bigger, faster particle collider, with a hefty 17 billion Euro price tag, are in question. Physicists Andrew Pontzen and Harry Cliff discuss if the new machine is really worth it. A place on the podium or disappointment in the Olympics can come down to the precise position of a foot or angle of the hips. Science reporter Ella Hubber visits the University of Bath to check out the motion capture tech that makes these measurements. New research suggests our close cousins, the chimpanzees, chat just as fast as humans. Professor Cat Hobaiter from the University of St Andrews tells us what chimp chats can teach us about the evolution of language. 75 years after making a groundbreaking discovery, Rosemary Fowler has finally been awarded with an honorary doctorate. University of Bristol chancellor, Sir Paul Nurse, shares how important it is to celebrate and recognise Rosemary’s achievements.Presenter: Victoria Gill Producers: Ella Hubber and Sophie Ormiston Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

Antarctica is a 'natural reserve, devoted to peace and science' - that’s according to an international treaty. But with visitor numbers at a record high, how does tourism fit into that – and what kind of impact is it having on its fragile ecosystem? We discuss whether tourists – and even scientists – should be allowed to go at all. Swimming in the Seine has been banned for more than a century because of pollution concerns. The main culprit? Human waste. We find out if it really will be safe in time. And every summer we ready ourselves for 'flying ant day' – that one day where winged ants take to the skies across Britain. Or do they?

We visit Wimbledon’s iconic Centre Court... but we’re not interested in the tennis, we want to know all about the grass. Just how important is science to cultivating the perfect playing surface? Also this week, we discuss the aims and ethics of human stem-cell-based embryo models in research after a new code of practice for the UK made headlines. And we answer a listener question about whether white paint could help tackle climate change. Send your burning science questions to [email protected].

It’s election time but over here in Science Land, we’re heading off to the seaside for our summer special. We chat seagulls with Professor Paul Graham on Brighton beach and find out why they are so misunderstood - from what we call them to why they pinch our chips. We bust some sun safety myths with dermatologist Dr Jess Felton and find out why ice cream is such a chemical marvel with chef Terri Mercieca. And we join in the festivities at the Royal Society’s Summer Science Exhibition.

Taylor Swift fans danced so hard they made the ground shake at her recent Edinburgh gig so this week we’re meeting Earth Scientists Emma Greenough and James Panton to measure the Cardiff show - and explain some Swiftie Seismology. We’re joined by the BBC’s disinformation and social media correspondent Marianna Spring and Cardiff University's Professor Martin Innes to talk the science of tracking election disinformation on social media. What’s in the election manifestos? BBC science correspondent Pallab Ghosh explains all. And Marnie dashes to Kew Gardens to meet horticulturalist Solene Dequiret, hoping to be in time to see two very foul-smelling plants in very rare bloom.
