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.
