Human embryos, Transit of Mercury, Fishackathon, Fat labradors

In a major advance in the field of embryology, scientists this week have kept human embryos alive in petri dishes for record amounts of time. The legal limit for keeping fertilised human embryos in the lab is 14 days, a cut-off point set in 1979. Back then, scientists were able to keep embryos alive for only a few days, meaning the limit was only a theoretical one. Advances mean that this week, in 2 papers, researchers have reached that limit. Professor Ali Brivanlou, Robert and Harriet Heilbrunn Professor of Stem Cell biology and molecular embryology at Rockefeller University is lead author on one of the papers, and Professor Bobbie Farsides is a clinical and biomedical ethicist at Brighton and Sussex Medical School. They join Adam to discuss the next steps for embryology. Should this limit curtail research?

Next Monday is the transit of Mercury. 13 times a century, Mercury passes directly between us and the Sun, and creates a pinprick shadow, a pixel of black for about 8 hours. This strange planet has no atmosphere, but a lot explosive volcanic activity. It has an eccentric orbit - meaning its distance from the sun fluctuates wildly. A Mercury year is 88 Earth days, but a Mercury day lasts almost two mercury years. David Rothery is a professor of Planetary Sciences at the Open University. He reveals how scientists study this planet and explains how, and how not to view the transit of Mercury.

Overfishing is one of the biggest threats to the health of our oceans. According to the UN, up to a third of the world's fisheries are overexploited or depleted. It is a huge complex problem with many inputs and outputs to compute. So who better to tackle it than a team of hackers? Recently, coders around the globe gathered to take on the challenge, in a 48-hour Fishackathon. Reporter Anand Jagatia went along and reports back to Adam

Most dog lovers will know that Labradors are particularly keen to eat anything, all the time, at any time. As a result, some are a bit corpulent, even obese. The cause is likely to be in their genes. A new study in the current issue of Cell Metabolism has identified that genetic basis for the perpetual hunger. Eleanor Raffan from Cambridge University, geneticist and vet, led the study. She explains to Adam how she gathered a cohort of dogs.

Are boys doing better than girls at maths and science?

Are boys doing better than girls at maths and science?

There’s a big “gender gap” between boys and girls in maths and science - that’s according to a new report out this week. Boys in England in years five and nine are now “significantly” outperforming girls in both subjects, the Trends in International Mathematics and Science Study suggests. Ben Garrod is joined by physicist Dr Jess Wade, from Imperial College London, and maths teacher and National Numeracy ambassador Bobby Seagull, to discuss the issue. Also this week, we discuss the mind-blowing effects of living in space on the human body and science journalist Caroline Steel joins us with her picks of the week’s science news, including the environmental impact of the North Sea collision and a study that suggests scientists should be cracking more jokes...

Better Than Gold: Critical Minerals

Better Than Gold: Critical Minerals

Critical minerals have hit the headlines of almost every news outlet this week as US President Donald Trump made his desires to mine them in Ukraine clear. These precious resources are a hot geopolitical bargaining chip thanks to our reliance on them in everything from mobile phones to wind turbines. This week, Inside Science unearths everything you need to know about critical minerals; what they are, why they’re critical, and what we do when there’s no more left to mine. Also this week, we come to the end of a laborious seven-year journey of collecting and identifying Scotland’s most valued Jurassic fossil. And Nature journalist Lizzie Gibney brings us her pick of the week’s science news, including moon landers and woolly mice.

AI in Science: Promise and Peril

AI in Science: Promise and Peril

This week, Google has launched a new AI tool called Co-Scientist. We hear from one researcher who has tried it out with stunning results. But how much should we trust tools like this - and what are the dangers?And what about the problem of AI generated text and images? We talk to an ‘image integrity analyst’ who hunts down fake or manipulated pictures in scientific papers. Finally, the planets of the solar system are coming into an unusual alignment. Astronomer Royal for Scotland Catherine Heymans shares how to glimpse the planetary parade.

Biotech Risks and Asteroid Anxiety

Biotech Risks and Asteroid Anxiety

Scientists gather this week to tackle emerging risks from cutting-edge biotech, echoing the landmark Asilomar conference that shaped genetic engineering safety 50 years ago. What new threats face us, and how can the scientific community stay ahead of them?Also in the programme: are you feeling asteroid anxiety? We take a closer look at the chances that ‘2024 YR4’ will hit us... We get the latest calculations on this space rock's potential collision course with Earth in 2032.And, as members of the Royal Society debate whether to expel Elon Musk from their ranks, we explore past fellows who rattled the establishment. Fellows meet next month to decide his fate.If you want to find out more about the history of genetic engineering - from the Asilomar conference to the present day - search for Matthew Cobb's series 'Genetic Dreams, Genetic Nightmares' on BBC Sounds.

US science in chaos

US science in chaos

The United States is the world’s science superpower. But right now, much of its research community is in a state of confusion.In the past few weeks, the Trump administration has issued a huge number of orders – amongst them, large funding cuts for scientific institutions. We unpick what the implications are for the country’s role on the global scientific stage.Also in the programme, we take another look at phone bans in schools. Why are the results of a recent study so different to the personal experience of teachers and students?And Britain has a new snake – and it’s apparently thriving. Where has it come from and should we be worried?To discover more fascinating science content, head to bbc.co.uk search for BBC Inside Science and follow the links to The Open University.

The World’s Biggest Iceberg

The World’s Biggest Iceberg

It’s the biggest story of recent weeks. Literally. Trillion-tonne iceberg A23a is on the move. But where is it headed and why – and what might it mean for the scientists and penguins in its path? And from a giant ‘megaberg’ to a giant pile of highly radioactive material, we find out what locking away a load of radioactive waste has in common with baking a cake. And we’re joined by science journalist Caroline Steel to guide us through this week’s science news. We’ll hear about the first study into whether banning phones in schools works, why scratching an itch might have benefits beyond just satisfaction, and the perfect formula to boil an egg... Presenter: Victoria Gill Producers: Sophie Ormiston, Ilan Goodman & Gerry Holt Editor: Martin Smith Production Co-ordinators: Jana Bennett-Holesworth & Josie HardyScience-backed boiled egg recipe:- You need two pans… and exactly 32 minutes - Keep one pan at 100 degrees Celsius (boiling) and the other pan at 30 degrees Celsius - Move the egg between the two every two minutes for 32 minutesEnjoy!To discover more fascinating science content, head to bbc.co.uk search for BBC Inside Science and follow the links to The Open University.

Climate scientist Mark Maslin and environmental psychologist Lorraine Whitmarsh discuss. Also this week, new clues about how life may have begun from a dusty space rock called Bennu, and New Scientist’s Graham Lawton brings us the science of the week, including AI’s ‘Sputnik moment’, the mice born with two fathers, and how often do unexpected discoveries happen?
