Science: Nuclear War Threat, Climate Change, Coronavirus Origins

As the war in Ukraine intensifies, Vladimir Putin raised Russia’s nuclear readiness level. The team discusses what this means about the likelihood of nuclear war. They also explore the unfolding humanitarian crisis in the country.

The latest Intergovernmental Panel on Climate Change report is out, and it focuses on impacts, adaptation and vulnerability. We hear from Swenja Surminski, head of adaptation research at the Grantham Research Institute on Climate Change and the Environment.

New studies into the start of the coronavirus pandemic are confirming what we’ve long suspected – that the virus originated at the Huanan food market in Wuhan. The team discusses the latest findings.

Moles – the animals that make holes in your lawn – are non-binary. Just one of a number of amazing facts to come out of the new book ‘BITCH: A Revolutionary Guide to Sex, Evolution & the Female Animal’. Hear from the author Lucy Cooke, who is challenging the sexist basis of much of the thinking about female animals. 

Stonehenge may have been built as a giant calendar. Though the claim itself isn’t new, the team explores a new theory from the archaeologist Tim Darvill which explains how it would’ve worked.

Science: Saving Children From Cancer, Greenhouse Gases, SpaceX Missions

Children with some of the most aggressive forms of cancer are being saved by a personalised medicine treatment programme in Australia. The Zero Childhood Cancer Program has saved more than 150 children who would’ve otherwise died. The team shares a moving interview with one of the parents. 

Lichens evolve even more slowly than you might think. The team examines new research into the abundant Trebouxia genus of lichen which appears to take around a million years to adapt to changing climate conditions.

Enhanced weathering – using ground-up rocks to draw carbon dioxide out of the atmosphere – is one of a number of technological carbon capture solutions being tested to try and mitigate against global warming. The team speaks to Professor David Beerling of the University of Sheffield, one of the scientists in the UK leading the development of this technique.

SpaceX has a suite of three missions planned to launch in its Polaris programme. The first aims to take its Dragon crew capsule higher into orbit than anyone has flown since the Apollo moon missions. The team shares what we know so far.

And they find out whether adult human brains can actually grow new neurons. Spoiler: it doesn’t look good.

Science: Tonga Volcanic Eruption, Roaming Genes Of Reindeers, Pterosaurs

Scientists scramble to understand the devastating Tongan volcano eruption, and modelling how societal changes might alter carbon emissions.

In this episode:

00:46 Understanding the Tongan eruption

On the 15th of January, a volcano in the South Pacific Ocean erupted, sending ash into the upper atmosphere, and unleashing a devastating tsunami that destroyed homes on Tonga’s nearby islands. Now scientists are trying to work out exactly what happened during the eruption — and what it means for future volcanic risks.

08:49 Research Highlights

The genes associated with reindeers’ roaming behaviour, and how fossilised puke has thrown up new insights into pterosaurs’ stomachs.

11:29 Modelling societal changes to carbon emissions

A team of researchers have modelled what humans might do in the face of climate change, and looked at how societal, political and technological changes could alter future emissions.
