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

What would cuts to Nasa mean for space science?
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. And Tim O’Brien, Professor of Astrophysics at the University of Manchester joins Victoria Gill in the studio to discuss the week’s other science news.

How can science help us fight wildfires?
In the past few days, UK firefighters have been tackling wildfires across the UK. As global temperatures rise, fires are likely to increase in strength and number. We hear from Rory Hadden, Professor of Fire Science at the University of Edinburgh, and Aidan McGivern, meteorologist and weather presenter from the Met Office.Presenter Marnie Chesterton has been behind the scenes at Cambridge’s Natural History Museum with Assistant Director of the University Museum of Zoology Jack Ashby.Also, the woman who came third in the Brighton marathon in the middle of her hen weekend. We hear from Dr. Ann-Kathrin Stock, neuroscientist at Dresden University Clinics and member of the international Alcohol Hangover Research Group about the science behind hangovers and why it might not be such a good idea to run a marathon whilst hungover.And science journalist Caroline Steel has been scouring the science journals.Presenter: Marnie Chesterton
