Single-celled microbes underpin all life on Earth, and even complex organisms like humans retain a surprising amount of their microbial heritage. Life began when free molecules became encapsulated in a lipid membrane and transformed into a self-replicating entity. Subsequently, multiple cells came together, forming a remarkable symbiosis that ultimately led to all complex, eukaryotic, cells and laid the foundations for multicellular life.

Understanding this microbial legacy has some surprising implications, such as explaining why some antibiotics have unwanted side effects.

Imaging is used every day in medical healthcare, and the likelihood is that if you go to hospital that you will receive an X-ray, ultrasound or CT scan. With increasing reliance on complex imaging and the NHS now at breaking point, this lecture asks whether we have become too reliant on imaging and if so, how that manifests in today’s healthcare.

This lecture assesses the potential advantages and disadvantages of such a system and what the potential solutions might be.

Financial intermediaries, like banks, mutual funds and brokers, who connect investors to firms (who need finance), have existed for thousands of years. Because they control a scarce resource, information, these intermediaries are expensive. Platforms, like crowdfunding platforms (organised meeting places for investors to meet firms) offer an alternative. Today's technological revolution is all about the competition between centralized intermediaries and decentralized platforms.

This lecture discusses the technological innovations that are responsible for this competition: crypto, big data, and AI.

This lecture looks at the development of juries in the common law world, addressing key questions about the role of juries in England and Wales today. 

Juries in modern English law are mainly used in criminal trials, civil trials, and coroners’ inquests, and the English jury system differs from other common law jurisdictions, some of which use juries more, less, or not at all. What are the strengths and weaknesses of the jury system, and do jury trials or bench trials deliver fairer outcomes?

Planet Venus is a hellish place and seemingly hostile to life, although recent measurements claimed the detection of biogenic signatures. Less than a billion years ago, Venus’s atmosphere underwent a dramatic runaway greenhouse effect rendering it likely to be uninhabitable.

This lecture will consider what can be learned about the possibility of catastrophic climate change on Planet Earth, in the light of thermodynamics and of what has happened to Earth’s twin, Venus.

How can we understand the war in Ukraine in the light of European history over the past century? Is Putin a '20th-century Hitler' as some have called him? What are his aims, and how do they compare with those of the Nazis during the Second World War? Why are the Ukrainians resisting the Russian invasion so fiercely?

This lecture attempts to explain the nature of the current conflict by setting it in its historical and geopolitical context.

Britain has one of the richest of all pagan heritages in Europe, defined as the textual and material evidence for its pre-Christian religions. The island is possessed of monuments, burial sites and a range of other remains not only from several distinct ages of prehistory, but also from three different major historic cultures.

This lecture will look at what we know of prehistoric worship, focusing on Stonehenge and the bog body known as Lindow Man, to examine the difficulties of interpreting evidence for ritual behaviour for which no textual testimony survives.

The emergence of the global Internet challenged the notion that states have sovereignty over what their citizens see and hear, and what they can say. Governments around the world shut or slow down internet access for political and security reasons, and prohibit the online publication of undesirable content. How are they able to do this, when so much of the world’s internet infrastructure is outside their control? And what are the prospects for future regulation of our online interactions?

No one has been left untouched by COVID-19. Many individuals have been left with the physical and mental health consequences of the virus- now known as long Covid.

This lecture looks at the medical issues, and the new therapies and treatments that are emerging. Those not physically infected by the virus continue to experience the broader impact of the virus; the increasing social inequalities and loss of employment, education and loved ones.

Most summers Tudor and Stuart monarchs took their court on an extended progress round the home counties staying at their own palaces and the houses of their courtiers. The cost and impact of hundreds of people, their horses and servants, was considerable; for the aristocratic hosts a royal visit was a momentous event.

This lecture draws on new research to reveal who they benefited, their impact on the economy, the landscape and on architectural ambition.
