Is Twitter an ephemeral technology, consisting of mundane chat about people's personal lives? Or can a study of its use help us to understand how we express our identities on and offline? Can Twitter be used for professional or academic activity, and should we try to separate our public and private digital personae? This lecture will address such questions, with the aid of slides of 140 characters and live tweets from the audience at UCL and on the internet.Authors: Claire Warwick (UCLDH), @clhw1, Melissa Terras, @melissaterras, #melissaterras (UCLDH); Claire Ross, @clairey_ross (UCLDH); Anne Welsh, @AnneWelsh (UCLDH)This lecture marks the 5th anniversary of Twitter on 21 March.

During a heart attack the cells that make up the muscle of the heart are subjected to a restricted blood supply, this is usually caused by a blood clot or a narrowing of the coronary arteries. If the blood supply is not restored quickly it will result in the death of the heart muscle, and to protect against this injury, blood clot prevention drugs, inflating balloons and artery bypass surgery are all used to restore blood flow as quickly as possible. Paradoxically, however, the very act of restoring such blood flow can also cause a significant amount of heart cells to die.In this lecture, Professor Yellon will discuss why this injury occurs, how simple techniques such as inflating a blood pressure cuff on the arm can protect the heart against such injury, and how developments in UCL’s laboratories are already benefiting patients at risk.

Is it true that juries rarely convict defendants in rape cases and are more likely to convict ethnic minority defendants than White defendants? And why can’t jurors resist going home at night and googling the defendant or tweeting about the case – against the express instructions of the judge. This lecture reveals the truth behind a number of widely held beliefs about juries in this country and examines why the internet may now be the biggest threat to our jury system.

In preimplantation genetic diagnosis (PGD), embryos are created by IVF and cells removed from these embryos for genetic analysis. Until recently, testing was solely for the disease the couple carried. The use of array-comparative genomic hybridisation and single nucleotide polymorphism arrays has entered the PGD arena. These techniques allow all chromosomes and many genes to be examined. The analysis of the whole genome prior to implantation brings ethical concerns. Will healthy couples opt for PGD to select their ‘best’ offspring?This lecture marks International Women’s Day - 8 March

Since the 'decade of the brain' in the 1990s an increasing range of previously taboo subjects have been examined by neuroscientists. These include autobiographical memory, aesthetics, love and of course consciousness itself. The rise of imaging techniques which provide engaging pictures of brain activity have added to the appeal. Of course plenty of other discplines within the arts as well as science put the brain at the heart of their project. But how effectively has neuroscience integrated these other approaches into its work? And should the direction of brain research be left to scientists anyway?This lecture marks Brain Awareness Week 14-20 March.

On 15 August 2007, six young men with origins in the Italian region of Calabria were ambushed and murdered in the German steel town of Duisburg. This was northern Europe’s St Valentine’s Day massacre, the worst ever mafia bloodbath outside Italy and the United States. Suddenly, journalists across the globe were struggling with what the New York Times called an ‘unpronounceable name’: ‘ndrangheta (en-drang-get-ah.) In the 1990s, the ‘ndrangheta placed itself in a leading position in the European wholesale cocaine market by dealing direct with South American producers. It is now thought to be the wealthiest and most powerful of Italy’s major criminal brotherhoods. But how, when, and why did it first emerge?

2011 is the 90th anniversary of the robot, first imagined as a character in a play, performed in Prague in 1921. It is also the 50th anniversary of the first use of robots in industry with the robot ‘Unimate’ for General Motors in 1961.Since the origin of robots they have undergone a number of transitions from the popular idea of the robot as a domestic, a vision popular from fiction such as the 1970's cartoon ‘The Jetsons’, to the last fifteen years imagining robots, not just for work, but to act as companions, exercise coaches for the elderly or stroke patients, and assistants for children with autism spectrum conditions.This lecture will explore the history of the robot, and how it has changed and been re-imagined in fiction and labs over the last 90s years.

When the tide is out, the Thames foreshore is the longest archaeological site in London. The remains cover a wide range of our long history and include prehistoric forests, a Bronze Age bridge, Saxon fish traps, Tudor jetties, later shipyards, watermen's causeways, and the hulks of boats, barges and ships. Our most recent study has even found evidence for bomb-strikes from the London Blitz, exactly 70 years ago. Much of this evidence is suffering from the river's increased erosion or by modern redevelopment. The Thames Discovery Programme team is training up a group of committed Londoners to survey the sites on a regular basis, recording the history on the foreshore before its washed away forever.

Unmanned robotic missions are essential for understanding the planets within our solar system. Current missions comprise of gentle landings combined with rovers to explore the local region. Due to the expense of such missions, and their sometimes unsuitability as scientific outposts, UCL’s Mullard Space Science Laboratory is developing Planetary Penetrators, which aim to land on planets at very high speed, penetrating the planet and implanting equipment just below the surface.This lecture will discuss the engineering difficulties of ensuring delicate instrumentation remains intact and operable after such high impact; and will highlight the biggest hurdle of all - convincing the space agencies to adopt the equipment in the first place! With a whole solar system waiting to be explored, in 40 minutes this talk will describe the UK Penetrator Programme - where we've been, what we've achieved and the opportunities for the future.

During World War II, Portugal was frantically trying to hold on to its self-proclaimed wartime neutrality, but was increasingly caught in the middle of the economic, and naval wars between the Allies and the Nazis. To complicate matters further, thousands of refugees, many of them Jewish, flooded into Lisbon seeking a passage to the United States or Palestine. This talk will present the little known, and yet vitally important history of the Portuguese capital, Lisbon, during World War II.This lecture marks Holocaust Remembrance Day.

Professor Alan Penn will describe the way that architects use space to sell you things. He shows how space creates patterns of movement and this brings you in contact with goods. In IKEA though, the story gets more interesting, here the designers deliberately set out to confuse you and in this way draw you into buying things that were not on your shopping list.

Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we're all hallucinating all the time; when we agree about our hallucinations, we call it "reality." Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.
