Are embryos made from skin cells the future of fertility treatment?

Scientists in the US have, for the first time, made early-stage human embryos by manipulating DNA taken from people's skin cells and then fertilising them with sperm. It’s hoped the technique could overcome infertility due to old age or disease. Marnie Chesterton is joined by Dr Geraldine Jowett from the University of Cambridge and Emily Jackson from the London School of Economics to discuss the science behind the research, and the ethical and legal issues it could raise. We also look back at th...

Does warm weather mean more rats in UK towns and cities?

Summer heatwaves and missed bin collections have created panic in the press that rat numbers in the UK are increasing. We ask Steve Belmain, Professor of Ecology at the Natural Resources Institute at the University of Greenwich for the science. This summer Wales became the first country in the UK to ban plastic in wet wipes, with the other nations pledging they will do the same. Over the past few weeks there’s been work to remove a giant mound of them, known as ‘Wet Wipe Island’ on the Thames in...

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 tradition...

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 an...

Is this finally the moment for UK tidal power?

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 fo...

Is everything we know about the universe wrong?

For the last week or so, the world of physics has had just one conversation. Have we found a new way of understanding the universe? And if so, what does this mean for our understanding of how we all came to exist – and even our fate? These big questions were prompted by new data from the Dark Energy Spectroscopic Instrument team at the Kitt Peak National Observatory in Arizona. To explain what was found, whether it’s right and just how excited we should be, we’re joined by astrophysics professor...
