About Us

Spring 2008 - UCL's Lunch Hour Lecture Series is an opportunity for anyone to sample the exceptional research work taking place at the university, in bite-size chunks. Speakers are drawn from across UCL and lectures frequently showcase new research and recent academic publications. Lunch Hour Lectures require no pre-booking, are free to attend and are open to anyone on a first-come, first-served basis.

The Yin and Yang of Cellular Communication - Audio

The lecture looks at how cells in emerging multicellular organisms have evolved ways of communicating with each other. The basic ‘yes’ and ‘no’ signalling was probably mediated by release into the extracellular space of substances which were available in abundance inside the cells – purine nucleotide ATP (molecule charged with energy – excitatory Yang) and its breakdown product adenosine (molecule devoid of energy – inhibitory Yin). The lecture will use examples from current research demonstrating how this dual system of conveying information from one cell to another has been preserved during evolution. Both substances are important modulators of cellular functions still playing often opposing roles in the peripheral tissues as well as in the central nervous system.

What can Venus, Mars and Titan tell us about Earth? - Audio

Several space missions of planetary exploration are currently underway, including Venus Express and Mars Express to our planetary neighbours and Cassini-Huygens to Saturn. In this talk, we will look at some of the results from these missions. Remarkably, these distant bodies can also tell us more about our own planet. Will the greenhouse effect run away here as it has at Venus, or might severe climate change happen as at Mars? Does Titan really show us what prebiotic Earth was like? We will also look at possible future space missions to these bodies.

Toad meets T-Rex: The Evolution and Diversification of Frogs - Audio

Love them or loathe them, frogs have a place in popular culture, from ‘Kermit’ to ‘Toad of Toad Hall’. The short, tailless body, large head, and long legs give a profile that is vaguely humanoid, but frogs are optimised for leaping rather than walking, a locomotor strategy that has been highly successful. Amongst amphibians, their body plan is unique, prompting questions as to its origin and evolutionary history. Some of the answers may be found in the fossil record of frogs, dating back 250 million years to the very beginning of the ‘Age of Dinosaurs’.

Tesla and the Art of Fugue - Audio

Although the field of ‘art and science’ – the fusion of art, science and technology – has existed for at least two decades, its validity and value are still questioned, often very forcefully, by both the artistic and scientific communities. This talk will examine some of the arguments both for and against art and science, drawing on material from Tesla, the open discussion forum on art and science at UCL Computer Science Department, and Fugue, Tesla’s first project. Perhaps some of the questions will be answered; however, it is equally likely that some new ones will be asked.

The Strange Case of Hart Crane and Samuel Greenberg - Audio

One of the most striking poems in the American poet Hart Crane’s first collection, ‘White Buildings’ (1926) is ‘Emblems of Conduct’. Long after Crane’s premature death in 1932, it emerged that this poem was in fact a mosaic of lines appropriated from an almost unknown New York poet called Samuel Greenberg, who had died in 1917 at the age of 23 – and whose work would probably have disappeared altogether had it not been plagiarized by Crane. This lecture will explore the nature and implications of this theft, and make a case for the long neglected work of the ill-fated Greenberg.

The Return of Syphilis - Audio

Between the early 1980s and the late 1990s, syphilis had essentially been eradicated in the UK. There is now an outbreak of syphilis with more diagnoses each year than at any time since the 1940s. This lecture will outline the nature of syphilis and its importance. Why is syphilis still so common worldwide when it is easy to diagnose and cure? How was syphilis eradicated in the UK? Why did it return and what does this say about the sexual health of the UK?

Reconstructing a Face After Cancer Surgery - Audio

Cancer of the mouth and face affects our swallowing, our speech and more importantly our self-perception and self-esteem. Therefore, reconstructive surgery of the mouth and face touches on the deepest human feelings about identity. The surgery offers the promise of allowing patients to eat, drink and communicate again through the wide variety of facial expressions and mannerisms that most people take for granted. In a ten-hour procedure, the patient’s cancer will be removed, and a new facial “flap” will be attached to the recipient’s blood vessels and nerves. The tissues are matched for colour and type and function. In the procedure the patient’s compliance and contribution to recovery is as important as the surgery itself.

The Pleasures of Driving - Audio

Nowadays we are all very aware of some the considerable disadvantages, danger and damage caused by automobile driving. Yet people continue to drive, even when suitable alternatives exists. This talk examines some of the historical reasons as to why people like to drive, looking in particular at some of the city driving of the 1960s and 1970s, and using films like ‘The Italian Job’, ‘Duel’, ‘Vanishing Point’ and ‘C’était un Rendezvous’ to explore notions of liberation, adventure, self-awareness and risk-taking. Given this history, should we be trying to restrict driving to purely essential journeys? Conversely, could it not be that driving should be reserved purely for occasions of personal pleasure?

The Sanitary and Phytosanitary Measures (SPS) Agreement: Law, Science and Globalising Markets - Audio

The SPS Agreement is one of the most innovative and controversial aspects of the World Trade Organization (WTO). This agreement uses science as a benchmark for assessing the legality of Member State regulation and has, in high profile cases such as EC Hormones and EC Biotech, been used to condemn regulatory measures as unlawful. The agreement, and the institutions which develop and apply it, walk a precarious middle line between trade and public health/environmental protection. This lecture will examine and evaluate the operation of this agreement, both before the WTO ‘courts’ and in the more co-operative setting of the SPS Committee.

The Making of Stars and Planets - Audio

Stars are formed from the interstellar medium and yet throughout their lifetime they feed material back into it. The interaction and exchange between the stars and the interstellar medium is therefore vital to a proper understanding of the mechanisms that drive our universe. Most stars are mainly hydrogen and are very hot. The interstellar medium on the other hand is usually cold, dusty and made up of hundreds of different atomic and molecular species. A complex chemical and physical evolution must take place in the stellar environments. Astrochemistry is the subject that studies this evolution. This lecture aims at giving an overview of this relatively new subject by reviewing recent advances in astrochemistry and its relevance to other fields such as cosmology and astrobiology.
