We’ve been rummaging through the Inside Science mailbox to pick out a selection of the intriguing science questions you’ve been sending in, and assembled an expert panel to try to answer them. Marnie Chesterton is joined by Penny Sarchet, managing editor of New Scientist, Mark Maslin, Professor of Earth System Science at University College London, and Catherine Heymans, Astronomer Royal for Scotland and Professor of Astrophysics at the University of Edinburgh, to get to the bottom of your scientific mysteries.Why is the moon sterile when the earth is so full of life? 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

Does the pandemic agreement make the world safer?
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.

Will the Hole in the Ozone Layer Close?
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

The mysteries of the ocean floor
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

How vulnerable is our power supply?
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
