Stroke is the leading cause of disability worldwide as well as a serious public health problem. It is the world’s biggest killer along with its close cousin, ischaemic heart disease: together, they were responsible for 15 million deaths around the globe in 2015. The most common type of stroke, ischaemic stroke, occurs when a blood clot disrupts the flow of oxygen and blood to the brain. One risk factor for ischaemic stroke is atrial fibrillation, which is the most commonly undetected type of irregular heartbeat and affects around a million people in the UK. Atrial fibrillation is scarcely discussed in popular media coverage of stroke and heart disease, but new research is demonstrating its significance in figuring out how and why strokes happen.
Today on The Provocateur I talk to Fiona Malone, a PhD candidate in biomedical engineering at the Galway-Mayo Institute of Technology, to discuss the silent killer that is atrial fibrillation. Join us for a lively discussion that covers the ins and outs of atrial fibrillation, the signs and symptoms of ischaemic strokes, Fiona’s research in building 3-D stroke simulations and what (if anything) cows have to do with strokes.

In this third installment of our miniseries for LGBT History Month 2018 we turn to the issues confronted by LGBT older adults and ageing. At the moment in the United States, there are around 2.7 million LGBT people over the age of 50 and about 1.1 million over the age of 65. These numbers are likely to double by the year 2050 and as developed countries around the world face up to the challenge of an ageing population over the next few decades, the particular problems associated with LGBT ageing will come more sharply into focus.
Today on The Provocateur I talk to Tim R. Johnston, Director of National Projects at SAGE USA, to discuss LGBT older adults and ageing in the United States. We talk about what makes LGBT older populations particularly vulnerable compared with their non-LGBT counterparts, the specific needs of transgender and bisexual older adults and how LGBT family dynamics and support structures differ from non-LGBT ones. We also touch on ageism, racism and disability issues in the LGBT community and how those might impact on ageing. Finally we look to the future and consider how the experience of Millennial LGBT ageing might be distinct from the experiences of the Greatest Generation and Baby Boomers.
It is widely recognised that global inequality is a serious problem. For instance, according to a Credit Suisse report in 2015, half the world’s wealth is owned by the top 1% of the world’s population. More than 60% of humanity, or 4.3 billion people, live below the realistic minimum standard of a decent life. And yet it is also widely recognised that there are ecological limits to material prosperity. In 2017, Earth Overshoot Day – the date when human resource consumption for the year exceeds the Earth’s biocapacity for the same year – occurred on 2 August, compared with 19 December when the concept was first introduced 30 years ago. With Trump vowing to exit the Paris agreement on carbon emissions, it looks like the picture of our planet’s ecological health is also getting worse and not better. How to reconcile the objectives of development with the objectives of sound environmental policy is a complex and pressing matter. How did we get here? And what can we do about it?
On this episode of The Provocateur I talk to Jason Hickel, Leverhulme Early Career Fellow in the Department of Anthropology at LSE, to discuss how we can bridge the gap between rich and poor on a finite planet. We first talk about Jason’s interest in the subject as an anthropologist before moving on to Jason’s case for his argument that global poverty is getting worse not better. We explore the history of development politics in the era of the Washington Consensus, the limitations of GDP as a measure of growth and new strategies for development in an age of both economic and ecological crisis.

Lisbon is probably best known today as one of the cultural capitals of Europe, but it is also remembered as the victim of one of the deadliest and most powerful earthquakes ever recorded in European history. The disaster struck on 1st November 1755, registering an estimated 8.5-9.0 on the modern moment magnitude scale. It triggered fires and a tsunami, in the end claiming as many as 100,000 lives. The catastrophe was not just a literal earthquake, though; it was also a cultural earthquake, as it brought simmering religious tensions to the fore, threw Portugal’s imperial ambitions into disarray and even arguably changed the course of the Enlightenment in the latter half of the 18th century.
Today on The Provocateur I interview Ryan Nichols, associate professor of philosophy at California State University Fullerton, to discuss the cultural aftershocks of the 1755 Lisbon earthquake. We explore the historical context of Lisbon and Portugal before the earthquake; the immediate effects of the disaster on Portuguese politics and society; discussions of the earthquake by 18th-century philosophers including Voltaire and Rousseau; how Ryan’s research in the cognitive science of religion can help explain the aftermath of the quake; and the wider cultural reverberations of this episode for the history and philosophy of science.

Pain is arguably one of the most central features of human experience. Many of us routinely experience pain in our lives, from the smallest cut to the most traumatic injury. Chronic pain, too, poses a serious challenge to our public health institutions. Philosophers have even argued that pain is morally bad: John Stuart Mill, for one, famously described happiness as “pleasure and the absence of pain”; the purpose of government, Mill thought, was to maximise the former and minimise the latter. Yet some individuals spend their entire lives feeling absolutely no pain at all and scientists are hoping to discover a breakthrough painkiller through analysing the genetic mutations that make people unable to feel pain.
This week on The Provocateur I talk to Domnhall Iain MacDonald, a PhD student in neuroscience at UCL, to discuss the biology of pain. Among other things, we cover the biological usefulness of pain to humans; whether non-human animals feel pain and the ethics of testing painful sensations on animals; and the latest frontiers in clinical pain research.
It is difficult to overstate the impact that technology has had on us, transforming our ways of life and making us more connected than ever before. Where once you had to take days or months to reach the other side of the world, now you can fly from London to Hong Kong in a matter of hours. Where not so long ago in human history we could only rely on candlelight, now artificial lighting is so ubiquitous that we take them for granted. The demand for ever faster connectedness is having unprecedented effects on our circadian rhythms: jet lag is perhaps the best known example of one way in which the body clock gets disrupted, but the problems associated with electricity are arguably even greater, precisely because our 24/7 society is completely dependent on it in order to function. Body clock disruption has been implicated in a whole range of diseases, from depression to cancer, so it is now more urgent than ever before that scientists try to understand the mechanisms of the body clock, so we are in a better position to fix it when it does go wrong.
In this episode of The Provocateur I talk to Aarti Jagannath, a research fellow at the Nuffield Department of Clinical Neurosciences at the University of Oxford, to help us unravel the mysteries of the body clock. We discuss the fundamentals of the body clock and what happens when it gets disrupted in a whole range of scenarios, from shift work to divers undergoing decompression to students pulling the occasional all-nighter. We also talk about the ways in which neuroscientists are trying to figure out how to reset our natural circadian cycle and even how some biologists are coming up with innovative treatments that exploit the body clock to better target cancer cells.
It is difficult to find someone whose life has not been touched in some way by cancer and indeed ‘the big C’ is probably one of the most well-known public health concerns. Ever since American scientists officially declared war on cancer in the 1970s, millions of lives have been saved through increased awareness, early detection and vast amounts of investment into research and development. But it seems we are no closer to the original target of eradicating cancer by the 2020s. According to the National Cancer Research Institute, the disease continues to kill more than eight million people worldwide every year, with 60 per cent of new cases occurring in the Global South. Overall cancer deaths are expected to increase by 60 per cent by 2030, largely due to an ageing global population. There is some hope however, as researchers around the world are racing to find the Holy Grail of cancer biology: a completely foolproof cure.
This week on The Provocateur I am joined by Ross Keller, a PhD candidate in Biomedical Sciences at Penn State College of Medicine, to discuss the ways in which he and other cancer biologists are pushing the boundaries of what is possible in the fight against cancer. We first briefly talk about what cancer is before going on to cover the traditional weapons used to tackle cancer, the ways in which cancer can outwit us and the startling new frontiers in cancer treatment. Ross has also written an excellent blog series covering the War on Cancer: the first part can be read here.
Climate change is almost never far from the environmental news agenda and the question of how to transition to a low-carbon economy in the face of an impending peak oil crisis is a serious problem for public policy. Solar power has often been touted as an answer, but its image is plagued by common perceptions that it is either expensive or inefficient or even both.
Today on The Provocateur I talk to Dr Jon Major, an EPSRC Research Fellow at the University of Liverpool, whose research aims to solve both these issues at once. Using the unique properties of a particular semiconductor called cadmium telluride, he and his team hope to develop solar cell technologies that are both cost-effective and also extremely energy efficient. Among other things, we discuss the nuts and bolts of how solar cells actually work, developments in solar technology since the 1950s, the incredible uses of solar power in developing countries and what the future may hold for solar power as a real low-carbon breakthrough.
While prejudice on the basis of sexual orientation is still widespread throughout the world, in recent decades laws have been enacted in various countries banning so-called conversion therapy: (typically) psychological attempts to change individuals’ sexual orientation from homosexual or bisexual to exclusively heterosexual. Advances in neuroscience in the not-too-distant future could mean that conversion therapy could be delivered in a ‘high-tech’ manner, for example by administering a drug that could rewire the neurochemical signals in our brains.
This possibility brings with it a raft of ethical issues and today on The Provocateur I talk to Brian Earp, Research Fellow at the Uehiro Centre for Practical Ethics at Oxford University, to broach these issues. We discuss the possible harms of conversion therapy and whether neuroenhancement-based conversion therapy in particular produces any distinctive harms, explore arguments in favour of the practice and touch on some policy implications.

Many of you will probably have come across meditation and mindfulness programmes at some point in your careers, especially those of you who are (former) students. But one of the problems with modern meditative practices in the West, argues Daniel Kharlas, is the fact that they are mostly depersonalized and so lack the ability to give patients the individual empowerment they need to change their lives for the better.
In this episode, I talk to Daniel, a masters student in Psychology at the University of Western Ontario in Canada to discuss the power of meditation. We discuss the effects of meditation on social and psychological wellbeing and the ways in which the digital revolution is transforming meditation through the rise of personalized apps. Daniel also offers some personal tips on being a better meditator and even coaches me through a short mindfulness routine you can try at home.
