Dame Jocelyn Bell Burnell Dec 19, 2018

Show notes

Jim Al-Khalili talks to astronomer Jocelyn Bell Burnell. Jocelyn Bell Burnell forged her own path through the male-dominated world of science - in the days when it was unusual enough for women to work, let alone make a discovery in astrophysics that was worthy of a Nobel Prize. As a 24-year old PhD student, Jocelyn spotted an anomaly on a graph buried within 100 feet of printed data from a radio telescope. Her curiosity about such a tiny detail led to one of the most important discoveries in 20th century astronomy - the discovery of pulsars - those dense cores of collapsed stars. It's a discovery which changed the way we see the universe, making the existence of black holes suddenly seem much more likely and providing further proof to Einstein's theory of gravity. Jocelyn Bell Burnell was made a Dame in 2008 and a year later became the first ever female President of the Institute of Physics. Producer: Anna Buckley.

Clive Oppenheimer on the volcanic offerings of our angry earth Dec 11, 2018

Show notes

Clive Oppenheimer has, more than once, been threatened with guns (a Life Scientific first?). He's dodged and ducked lava bombs and he's risked instant death in scorching and explosive eruptions. He studies volcanoes; science that by necessity, requires his presence at the volcanic hotspots of the world. It was at the lip of a bubbling lava crater on one of the earth's most active volcanoes, Mount Erebus in Antarctica, that he met the film and documentary maker Werner Herzog. The two became friends and went on to make a volcano movie together. Clive, who's Professor of Volcanology at the University of Cambridge, tells Jim academics and film makers share the same complementary skill set: thorough research, slick location recording and a familiarity with rejection as 9 out of 10 film pitches (or grant proposals) are turned down! As well as a forensic fascination with the dramatic impact of ancient and modern volcanism on the landscape, Clive discusses how multiple scientific disciplines are now needed to understand the complex historical, archaeological, climatological and environmental impacts of the earth's volcanic eruptions. He wades into the bitter academic row about what did it for the dinosaurs 65 million years ago: meteorite or volcanism? And he details the importance of Mount Pinatubo's 1991 eruption in the Philippines for our deeper understanding of anthropogenic climate change.

Sky at Night presenter Maggie Aderin-Pocock Dec 04, 2018

Show notes

Maggie Aderin-Pocock has been fascinated by space since she was a young child. When she was six years old she caught the bug when she saw a picture of an astronaut on the front of a book in her primary school library. As a teenager she built her own telescope.

After studying physics and mechanical engineering, Maggie worked in industrial research before returning to her first love, astronomy, when she managed the building of an instrument on a giant telescope in Chile. Now, she spends her time presenting TV programmes, in particular the BBC’s Sky at Night, and inspiring the next generation of schoolchildren to become scientists. Maggie’s come a long way since her own childhood. Her parents separated when she was four years old, and their prolonged custody battle meant she attended 13 schools in as many years. In addition, she was diagnosed as dyslexic and put in remedial classes where she wasn't ever expected to achieve academically.

Banning chemical weapons with Alastair Hay Nov 27, 2018

Show notes

Alastair Hay, now Emeritus Professor of Environmental Toxicology at the University of Leeds, is a chemist who’s had a dual career as an academic researcher and an outspoken activist and campaigner. The common theme has been the application of his knowledge to how chemicals affect our lives, in the workplace and during conflicts. Alastair Hay is best known for his work to rid the world of chemical weapons, a concern about this horrific form of warfare that goes back to the use of Agent Orange in the Vietnam War. His work culminated in the Chemical Weapons Convention, which came into force in 1997, outlawing their production, stockpiling and use.

He spent his childhood in Zimbabwe and returned to the UK when he won a scholarship from Shell to study chemistry in London in the late 1960s. After a spell working on the biochemistry of animals, including a stint at London Zoo where one of his more difficult jobs was taking blood from penguins, he moved on to studying the effects of chemicals on humans.

Jim al-Khalili talks to Alastair Hay about his love of chemistry and his shock to see that chemical weapons are still being used over twenty years after the signing of the Convention.

Formula One engineer Caroline Hargrove Nov 20, 2018

Show notes

How do you convince Formula One racing drivers that they are speeding round the race track at Le Mans when, in fact, they are sitting in a simulator in the McLaren offices in Woking? Apparently it’s all about getting the vibrations right. Racing drivers really do drive by the seat of their pants. They’re also highly attuned to the sound f the engine and instinctively associate different sounds with different speeds. When Caroline Hargrove started trying to build a driveable model of a Formula One car many thought it just wouldn’t be possible. Today, all the major manufacturers of Formula One cars use simulators to help them design faster cars and improve driver performance. Caroline talks to Jim Al-Khalili about how she stumbled upon a job in Formula One and stayed for twenty years. And why she now wants to build digital twins for human beings. Producer: Anna Buckley

Mike Stratton and cancer genes Nov 13, 2018

Show notes

When Michael Stratton was a young doctor he would diagnose cancer by studying tissue samples under a microscope. However, over the past 30 years he’s been advancing our understanding of this disease down at the level of the genes themselves, so that we are now able to read the DNA of a cancer. This had led to new diagnoses and treatments.

Mike Stratton’s first foray into genetics culminated in the discovery of the BRCA 2, one of the main genes involved in hereditary breast cancer. Following this painstaking detective work he and the Institute for Cancer Research became embroiled in a patent dispute with his collaborators. And at the beginning of the 21st century, he set himself the hugely ambitious goal of identifying all the mutations in DNA that led to every type of cancer. His critics said it was a crazy idea, but Mike and his colleagues at the Sanger Centre, just outside Cambridge have done it.

Detective of the mind Dr Suzanne O'Sullivan Nov 06, 2018

Show notes

Suzanne O'Sullivan has been described as “a detective of the mind”. She’s a neurologist who helps some patients with the strangest of symptoms, from so-called ‘Alice in Wonderland’ seizures to those suffering from temporary blindness or paralysis, and that turn out to originate in their subconscious minds. By the time these people get to see Dr Suzanne O’Sullivan they’ll often have been to many specialists, undergone a range of tests and given a variety of diagnoses. Suzanne’s an expert on epilepsy, and the unusual ways that seizures can manifest themselves, who currently works at University College Hospital in London and for the Epilepsy Society. As well as diagnosing and treating patients, Suzanne has also written books about some of her most memorable, and frankly bizarre, cases. Her first book, It’s All in Your Head, which won the Wellcome Book prize in 2016, describes many of her case studies involving patients whose illnesses are psychosomatic. But, she argues that this is an area of medicine that has not been studied deeply enough yet. After all, for the patients themselves, these debilitating symptoms are all too real.

Noel Fitzpatrick on becoming a supervet Oct 30, 2018

Show notes

For all his success as a Supervet on TV and as a pioneering orthopedic surgeon, Noel Fitzpatrick insists that his life has been full of failures. He didn’t enjoy studying for his specialist vet exams and spent ten years working as an actor before setting up his veterinary practice, Fitzpatrick Referrals. Determined to offer animals access to medical treatments and facilities that are more commonly reserved for humans, he has pioneered several new surgical procedures for small animals, specialising in spinal injuries and creating bionic limbs. The prosthetic leg he made for a German shepherd dog Storm was the first of its kind, inspired by the method that was used to rebuild the arm of one of the victims of the 7/7 bombing in London. And he built the world’s first prosthetic paws for a cat called Oscar whose feet had been crushed by a combine harvester. Now he’s on a mission to break down the barriers between human and veterinary medicine so that both animals and humans can benefit from cutting edge research, without the need to do experiments on animals.

Jacqueline McGlade on monitoring the environment from space Oct 23, 2018

Show notes

An ecologist who fell in love with computing, Jacqueline McGlade pioneered the use of satellites study the state of the global environment. Today thanks to programmes like Google Earth, we can see the surface of the earth in great detail. But when Jacqueline was a student, earth observation satellites were used for weather forecasting and not much else. Early in her career, she used satellite images to study fish populations, thinking it would be useful to know not only how many fish were in the sea but where they were likely to be. Few believed such an ambitious undertaking would be possible but, after a spell in Silicon Valley, Jacqueline found a way. The moving maps she created changed the way oceanographers and fishermen viewed the sea. In the early 1980s, she started trying to model the global climate using some of the earliest supercomputers and a roomful of un-networked PCs. As Executive Director of the European Environment Agency, she introduced monitoring systems for a range of environmental indicators and insisted that the information provided by Europe’s first earth observation satellite should be made available to everyone for free. She retired from her latest job, as chief scientist to the United Nations Environment Programme last year and now lives in a mud hut in the Masai Mara, having married a Masai chief.

Rachel Mills exploring the sea floor Jun 19, 2018

Show notes

Professor Rachel Mills is a marine geochemist who studies the sea floor and hydrothermal vents, where water erupts from the earth's crust at 360 degrees. The thick plumes emit many metals such as copper, gold, iron and rare earth minerals that are deposited on the sea bed. Rachel's career has taken her all over the world and 4km deep under the ocean in small submersibles. These journeys are exciting and terrifying as samples are taken to understand how the metals travel many thousands of miles. The metals are involved in creating nutrients that supply the ocean's food chain and control carbon uptake. There is also a lot of interest in mining the valuable deposits but can this be done without upsetting the ocean's eco-system?
