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.

The climate cost of war

The climate cost of war

As conflicts in the Middle East and Ukraine continue to dominate the news, many Inside Science listeners have been in touch with the same question: What is the carbon footprint of war? How significant is the impact – and is it crass to even talk about it? We’re joined by Benjamin Neimark from Queen Mary University in London. Also this week, we chat to the incoming DG of Europe’s particle-smashing facility Cern, what have we learnt by defrosting an extinct big cat and, the beetle that could ruin Christmas...

Nuclear medicine shortages and Jane Goodall on COP29

Nuclear medicine shortages and Jane Goodall on COP29

A shortage of medical isotopes used to detect cancer has experts concerned that the shortfall could be delaying diagnosis and could even be costing lives. Exactly what these nuclear medicines are and how they are made is key to understanding the national scarcity. So, we’re going back to basics and learning all about medical isotopes. We also speak to world-famous conservationist and primatologist Jane Goodall who, now aged 90, continues to travel the globe campaigning to protect the natural world. Dame Goodall reflects on a life of studying our closest living animal relatives, chimpanzees, and as COP29 gets under way, speaks about the “closing window of time” to turn the tide on climate change and nature loss. Also this week, we answer the listener question “Why don’t we just throw nuclear waste into volcanoes?” and can Marnie spot AI vs real poetry?

COP29: Are climate summits working?

COP29: Are climate summits working?

This year is set to be the world’s hottest on record, likely shattering the aspiration to limit global warming to 1.5C above pre-industrial levels. So where does this leave COP29, the upcoming UN climate conference in Azerbaijan? This week Inside Science is asking, are climate summits really working? What is the point of them - and are they doing enough? Joining Marnie Chesterton to discuss this are: - Joanna Depledge, expert on international climate negotiations at the University of Cambridge - Mark Maslin, climate change professor from University College London (UCL) - Jim Watson, professor of energy policy, also from UCL Presenter: Marnie Chesterton Producers: Ella Hubber, Sophie Ormiston & Gerry Holt Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth If you want to test your climate change knowledge, follow the links on this page to The Open University to take a quiz.

Whatever happened to graphene?

Whatever happened to graphene?

Twenty years ago this week two physicists at the University of Manchester published a ground-breaking paper describing the extraordinary qualities of graphene. The thinnest and strongest material known to exist – and better at carrying electricity than any metal – its discovery was hailed as revolutionary. But two decades on, it doesn’t seem to have changed the world, or if it has, it is doing so very quietly. So, what happened? We go on the trail of graphene, meeting Nobel Prize winner and Godfather of Graphene Andrew Geim, and learning what it has – and hasn’t – done and what might be next... Also this week, how to kill an asteroid and we talk the “other” COP with chief scientific adviser to the government, Dame Angela McLean.

Are our carbon sinks failing?

Are our carbon sinks failing?

The Earth’s natural carbon sinks absorb half of our pollution. But now, they appear to be collapsing. Why is this happening – and will we be able to reach our climate goals without them?Also this week, why a psychologist won the Nobel Prize in Physics, the culprit behind the second biggest mass extinction event, and does playing video games make you smarter?Presenter: Marnie Chesterton Producers: Sophie Ormiston, Ella Hubber, Anna Charalambou Editor: Martin Smith Production Co-ordinator: Andrew Rhys Lewis BBC Inside Science is produced in collaboration with the Open University.

Should we bring back extinct animals?

A woolly mammoth by 2028.That’s the bold claim from US company Colossal Biosciences, who say research is under way that will make this possible.But even if we have the technology to bring back a long dead species, should we? We hear the arguments for and against de-extinction.Also this week, what will Europa Clipper find when it heads to one of Jupiter’s icy moons and how to win a Nobel Prize.

Could coal shut-down mark new era for energy?

Could coal shut-down mark new era for energy?

“That’s the end of coal in the UK for electricity.” The UK’s last coal-fired power station has closed, ending Britain's 142-year reliance on coal. But what difference will the closure of Ratcliffe-on-Soar make – and could it mark a new dawn for clean energy? After 20 years of research into microplastics and headline upon headline on their potential harms, how much do we really know about these tiny particles? Also this week, Marnie turns lab rat for a navigation experiment, and why are we all so obsessed with Moo Deng?
