Tooth and Claw: Killer Whales Jul 07, 2025

Show notes

Investigating the black-and-white apex predator of the sea – the killer whale! Able to predate even great white sharks, this marine mammal is the largest member of the dolphin family. From tropical seas, to the Arctic and Antarctic, killer whales (or orcas) are found across the world. Living in family groups and often led by a post-menopausal matriarch, killer whales have passed on their hunting methods, which vary depending on which prey they specialise in hunting, through the generations.

Presenter Adam Hart finds out about the killer whales incredible social behaviours (such as wearing salmon as hats) and hears how a dog is helping killer whale researchers access a gold mine of information about this predator. He also hears what challenges killer whale populations are facing and why killer whales may be attacking boats off the coast of the Iberian peninsula.

Contributors:

Dr. Leigh Hickmott, whale biologist and conservationist, who is an expert on Pack Ice killer whales, and whose research uses them as indicators to assess human disturbance of marine habitats.

Dr. Deborah Giles, who is an expert on Southern Resident killer whales, based with the SeaDoc Society, a program of the Karen C. Drayer Wildlife Health Center at the UC Davis School of Veterinary Medicine.

The Life Scientific - Tim Peake Jun 30, 2025

Show notes

What's it like living underwater for two weeks? What's the trickiest part of training to be an astronaut? What are the most memorable sights you see from space? Several extreme questions, all of which can be answered by one man: Major Tim Peake.

After a childhood packed with outdoor adventures, via the Cub Scouts and school Cadet Force, Tim joined the British Army Air Corps and became a military flying instructor then a test pilot; before eventually being selected as a European Space Agency (ESA) astronaut. In 2015, Tim became the first British ESA astronaut to visit the International Space Station.

Over the course of a six-month mission, he took part in more than 250 scientific experiments and worked with more than two million schoolchildren across Europe.

In a special New Year’s episode recorded in front of an audience at London’s Royal Society, Professor Jim Al-Khalili talks to Tim about his lifelong passion for adventure, the thrill of flight and why scientific experiments in space are so important.

Presented by Jim Al-Khalili Produced by Lucy Taylor

How does heat affect our health? Jun 03, 2025

Show notes

What effect will warming temperatures have on health? One place to look for answers is Bulgaria. In the summer of 2023, Bulgaria experienced numerous heatwaves, leading to the country experiencing one of the highest rates of heat mortality in Europe. But how are these numbers calculated? How exactly does heat affect us? Who is most likely to suffer from ill health due to heat? And how can we protect ourselves in an increasingly warming world? Along with a panel of experts, Claudia Hammond will explore these questions and more with a live audience at the Sofia Science Festival in Bulgaria. Are we prepared for how rising temperatures will affect our health? This programme aims to find out.

Unstoppable: Inge Lehmann May 12, 2025

Show notes

From growing up in a progressive Denmark to studying mathematics at a gender-segregated Cambridge University, Inge Lehmann had to power through the shock of cultural change to pursue her love of mathematics. Whilst managing several seismological stations, Inge notices the peculiar readings in the data she was collecting. Was the Earth’s composition actually different to what the experts had thought?

Dr Julia Ravey and Dr Ella Hubber tell the story of Danish seismologist Inge Lehmann who used earthquakes to uncover the truth about the composition of the Earth’s inner core. With contributions from Dr Lif Lund Jacobsen and Dr Trine Dahl-Jensen.

Unstoppable: Tebello Nyokong May 05, 2025

Show notes

Born under Apartheid in South Africa, Prof Tebello Nyokong and her family uprooted their lives to escape the unequal education system enforced upon Black South Africans. After herding sheep proved she could do anything a boy could do, Tebello ended up studying science and found a love for chemistry. In the face of limited opportunities, she once again uprooted her life and took her studies oversees, but this was when she was introduced to something huge: a new, ground-breaking cancer treatment. Now Tebello is using nanotechnology to get this therapy off the ground, all while she fights to make Africa a science superpower.

Unstoppable: Kura Paul-Burke Apr 28, 2025

Show notes

This week, how Māori marine scientist Kura-Paul Burke is combining indigenous knowledge with marine science to save the oceans that are so integral to her heritage.

Growing up in 1970s New Zealand, Kura-Paul Burke faced stigma due to her Māori roots. But, after finding herself studying marine science as an adult, Kura leaned on her heritage to take on a problem where many had already failed: restoring a lost population of precious, green-lipped mussels. Discover how Māori ancestresses, tribal elders and centuries-old knowledge inspired the ingenious methods of Aotearoa's first female Māori professor of marine science.

Unstoppable: Tu Youyou Apr 14, 2025

Show notes

During a time of global political tension, the Chinese government set up a top-secret project to help communist troops in North Vietnam struggling with malaria. And tasked with this mission was young scientist, Tu Youyou. With a drive to help people after falling ill as a teenager and seeing the horrors of malaria firsthand, Tu turned to traditional Chinese medicine to look for potential treatments. And, after finding a hit, decided she should be the one to trial it...

Named as arguably the most important pharmaceutical discovery in the last half-century, winning the 2015 Nobel Prize, discover how one woman used an overlooked herb combined with modern science to ultimately save millions of lives.

Unstoppable: Purnima Devi Barman Apr 07, 2025

Show notes

Dr Julia Ravey and Dr Ella Hubber are both scientists, but it turns out there’s a lot they don’t know about the women that came before them. In Unstoppable, Julia and Ella tell each other the hidden, world-shaping stories of the scientists, engineers and innovators that they wish they’d known about when they were starting out in science. This week, the story of an Indian conservationist who combines stork preservation with female empowerment. On the banks of the Brahmaputra River in the Indian state of Assam, a young Purnima Barman discovers a love of storks whilst singing songs with her farmer grandmother. Fast forward decades later, she has created a community like no other by recruiting an army of over 20,000 village women to bring the Hargila storks from her childhood back from the brink of extinction. With their shared goal of restoring the relationship between the people and the wildlife, discover how Purnima is empowering women in the face of gender inequality.

The Life Scientific - Anna Korre Mar 25, 2025

Show notes

As the famous frog once said, it's not easy being green. And when it comes to decarbonising industry, indeed, reducing emissions of all sorts, the task is a complex one.

Fossil fuels are used to manufacture some of mankind’s most ubiquitous products, from plastics to cement to steel; and even in areas where we’re trying to improve our footprint, there are repercussions. Mining lithium for electric car batteries isn’t exactly without impact. Add to the mix stories of corporations prioritising profits, and governments focusing on short-term popular policies – and it would be easy to feel disheartened.

Professor Anna Korre says her role is to be the champion of science in this debate: providing clear evidence to help reduce environmental impacts, while allowing vital production processes to continue.

Anna is an environmental engineer at Imperial College London and Co-Director of the university’s Energy Futures Lab. Her work has led to a risk model that's now used in mining operations around the world – and her current research into underground CO2 storage could hold the key to decarbonising British industry. But as she tells Jim Al-Khalili, social and family expectations when she was growing up in her native Greece meant her successful career in engineering very nearly didn't happen...
