More than 2,000 marine scientists have come together at the One Ocean Science Congress in Nice, France. It is a gathering that will bring marine experts from all over the world together to share the latest discoveries about the health of our seas and oceans. It is an issue at the centre of the world’s attention, because from 9th June, leaders and negotiators from 200 countries will arrive in Nice for the crucial United Nations Conference on the Oceans (UNOC3). Presenter Victoria Gill is joined by Murray Roberts, Professor of Marine Biology at the University of Edinburgh to find out what is at stake when leaders come together to work out a global plan to save our oceans from multiple threats, including climate change, pollution and overfishing. Professor Amanda Vincent from the University of British Columbia in Canada joins the Inside Science team to reveal her insights into the destruction caused by the controversial fishing practice of bottom trawling, which she explains is devastating marine life. Victoria also joins a team of acoustic marine scientists on their research boat the “We Explore” off the coast of Nice to listen for whales and dolphins under the surface. Their sound recordings reveal how animals of different species eavesdrop on each other and how to stop boat noise from drowning out whale communication. We also meet a team from a charity in Plymouth that is helping people who are living with poor mental health by prescribing ocean-based activities. Freyja Thomson-Alberts from the organisation the Ocean Conservation Trust explains why the ocean is central to our physical and mental wellbeing.Presenter: Victoria Gill Producers: Dan Welsh, Clare Salisbury, Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

Are new organisms going to evolve to eat microplastics? And did Nikola Tesla really find a way of creating free electricity?Listen in as we try to uncover the answers.Presenter: Marnie Chesterton Producers: Dan Welsh & Debbie Kilbride Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

The World Health Organisation has agreed a treaty looking at tackling the issue of future pandemics. It’s hoped it will help to avoid some of the disorganisation and competition for resources like vaccines and personal protective equipment that were seen during the Covid-19 outbreak. Victoria Gill speaks to global health journalist Andrew Green from the World Health Assembly in Geneva to ask if this will help to make the world a safer, fairer place.Marnie Chesterton visits Kew Gardens in London to speak to some of the artists and scientists behind a new installation that’s digitally recreated one of the site’s most famous trees.As it’s announced the iconic American children’s TV programme Sesame Street is moving to Netflix, Victoria speaks to the programme’s scientific advisor and Associate Professor of Elementary and Environmental Education at the University of Rhode Island, Sara Sweetman, about exactly how the likes of Elmo, Big Bird and the Cookie Monster go about informing young people about science.And Caroline Steel joins Victoria in the studio to look through the most fascinating highlights from the world’s scientific discoveries this week.

40 years ago scientists in Antarctica discovered a hole in the Ozone layer. The world acted quickly, phasing out harmful CFCs or chlorofluorocarbons. Evidence suggests the hole has been getting smaller. But in 2025, there are new pollutants threatening to slow progress. Eloise Marais is Professor of Atmospheric Chemistry and Air Quality at University College London and tells Victoria Gill about her work monitoring the impact of space travel on the Ozone layer.It's the first day of the traditional ‘bathing season’ when wild swim spots are regularly tested throughout the UK summer. Victoria asks Professor of Environmental Microbiology and Health at Lancaster University, Roger Pickup to break down the science behind our water quality classifications. And May also means wildflowers. Dr Sarah Scott is pollinator ecologist and toxicologist at Cambridge university. She has a warning that planted in the wrong place, wildflowers could be harming bumble bees.Gareth Mitchell, broadcaster and lecturer in science communication at Imperial College London is in the Inside Science studio to bring Victoria new scientific findings which will shape our future.Presenter: Victoria Gill Producers: Clare Salisbury, Dan Welsh, Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

It’s often said we know more about the surface of the Moon than we do about the Earth’s deep sea, and a new study is backing that up. Research from the Ocean Discovery League says just 0.001% of the world’s deep seafloor has ever been seen by humans.We speak to lead author and deep sea explorer Dr Katy Croff Bell and marine biologist Dr Anna Gebruk from the University of Edinburgh, to ask whether we should be making more effort to investigate our oceans.As events take place to mark the 80th anniversary of Victory in Europe Day, presenter Victoria Gill also speaks to Professor David Edgerton from King’s College London to discuss what impact the Second World War had on scientific research and innovation.We’re also joined by Penny Sarchet, managing editor at New Scientist, to look through some of the top science stories you might have missed this week. And as David Attenborough celebrates his 99th birthday with the release of his latest film Ocean, we take a trip through the archives to hear some of his finest moments from more than 70 years of broadcasting.Presenter: Victoria Gill Producers: Clare Salisbury, Dan Welsh, Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

Severe power cuts hit Spain, Portugal and parts of France this week, cutting the lights and stopping flights, trains, and ATM machines in their tracks. The Spanish grid operator has said it’s ruled out a cyber-attack, but the reason behind what happened is still unclear. We speak to Keith Bell, Professor of Electronic and Electrical Engineering at the University of Strathclyde, and David Brayshaw, Professor of Climate Science and Energy Meteorology at the University of Reading, to ask whether the UK’s power supply could be just as vulnerable to a major blackout.Presenter Victoria Gill hears about how cyborg cockroaches are being developed to try to help at disaster scenes. We’re also joined by science journalist Caroline Steel to discuss the week’s standout science news. And we find out how a critically endangered salamander, the axolotl, could hold the biological key to repairing damaged spinal cords.Presenter: Victoria Gill Producers: Clare Salisbury, Dan Welsh and Gerry Holt Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

Progress has been made in our search for alien life. So announced a team of scientists from Cambridge university last week who, using a powerful space telescope, have detected molecules which on Earth are only produced by simple organisms. All in all, it’s been a busy week for space science. And all against a backdrop of a US government request to cut NASA’s funding. The proposals would need to be approved by the Senate before any cuts are made. But scientists and journalists are asking what it could mean for the future of space science around the world. Science journalist Jonathan Amos and space researcher Dr Simeon Barber discuss.Professor of Planetary Sciences at the Massachusetts Institute of Technology Richard Binzel updates the programme on plans to learn from an asteroid called Apophis, due to fly past us in four years time. Back on Earth, or rather in it, Victoria Gill gets up close to Roman remains which show that gladiators once fought lions.

Why does the UK, an island shaped by its strong tides, still not have any major tidal energy schemes? Plans for tidal barrages in the UK seem to be regularly discussed but never come to fruition, but now a new report has suggested that a tidal lagoon should be created in the Severn Estuary to generate electricity. Guest presenter Tom Whipple speaks to Chair of the Severn Estuary Commission, Dr Andrew Garrad, about whether this will finally be the moment for tidal power that we’ve been waiting for. Also, earth scientists around the world are trying to understand why the 7.7 magnitude earthquake which struck Myanmar last weekend was just so devastating. Dr Ian Watkinson, structural geologist at Royal Holloway university, tells us about a theory that a seismic event called a ‘supershear earthquake’ took place. And a new bat is causing controversy in the baseball world! The ‘Torpedo Bat’, engineered by an MIT physicist, has helped the New York Yankees crush records in Major League Baseball.
