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...

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?

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

It’s our Halloween special from a rain-soaked Jodrell Bank in Cheshire.

We find out what you can see in a dark, dark Halloween night sky with space-watcher and Professor of astrophysics Tim O’Brien.

Also this week, we meet some blood-sucking leeches, the horrors of pumpkin waste and could zombies ever be real?

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.

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

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.

“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?

The images beamed back to Earth of the first civilian spacewalk have prompted a very pertinent question from one Inside Science listener:

What effect is space travel having on our climate?

We're used to delving into the carbon footprint of Earth-bound travel – so this week we’re going to explore the impact of the rapidly growing space industry on our climate.

How does a rocket launch compare to a flight taking off? Do we even know the true cost yet – and if it’s significant, what might the solution be?

Also on the programme, a personal perspective from a remote island on worrying seabird declines, the results of a project to refreeze Arctic sea ice, and why new evidence unearthed about the Falkland Islands suggests it may once have looked very different...

Lab-grown meat, cultivated meat, cultured meat, in-vitro meat - whatever you call it, the industry claims it could be a game changer. Not just economically, but for feeding the planet in a sustainable way.

But is it too good to be true? And will people even eat it?

In this special episode of Inside Science, we take a deep-dive into lab-grown meat; visiting a production facility to see how it's made, hearing about the nuanced perspectives of British farmers, asking if this new industry can learn from the failings of GM foods, and trying to figure out what the true environmental costs of entirely new way of producing food really is.
