25 November 2015 There is a long history of debate about biological sex differences and their part in determining gender roles, with the 'biology is destiny' mantra being used to legitimise imbalances in these roles. The tradition is continuing, with new brain imaging techniques being hailed as sources of evidence of the 'essential' differences between men and women, and the concept of 'hardwiring' sneaking into popular parlance as a brain-based explanation for all kinds of gender gaps. But the field is littered with many problems. Some are the product of ill-informed popular science writing (neurotrash) based on the misunderstanding or misrepresentation of what brain imaging can tell us. Some, unfortunately involve poor science, with scientists using outdated and disproved stereotypes to design and interpret their research (neurosexism). These problems obscure or ignore the 'neuronews', the breakthroughs in our understanding of how plastic and permeable our brains are, and how the concept of 'hard-wiring' should be condemned to the dustbin of neurohistory. This talk aims to offer ways of rooting out the neurotrash, stamping out the neurosexism and making way for neuronews. Gina Rippon is Professor of Cognitive NeuroImaging in the Aston Brain Centre at Aston University. She has a background in psychology and physiology and uses brain imaging techniques such as Magnetoencephalography (MEG), functional Magnetic Resonance Imaging (fMRI) and electroencephalography (EEG) to investigate the relationship between patterns of brain activation and human sensory, cognitive and affective processes. Most recently her work has been in the field of developmental disorders such as autism. She has served as President of the British Psychophysiology Society (now the British Association of Cognitive Neuroscience). She also writes and speaks on the use of neuroimaging techniques In the study of sex/gender differences, recently featured in the BBC Horizon programme "Is your Brain Male or Female?". She is additionally involved in activities around the public communication of science, particularly in challenging the misuse of neuroscience to support gender stereotypes, and in work to correct the under-representation of women in STEM subjects. She has recently been appointed as an Honorary Fellow of the British Science Association.

7 October 2015 Water may seem the most ordinary of substances – it pours from our taps and falls from the sky – but you would be surprised at what a profoundly strange substance it is. It bends the rules of chemistry and defies easy scientific understanding. Without this rebel behaviour, however, none of us would exist. Alok Jha will change the way you look at water – showing how it has shaped life on earth, and how this molecule connects you and everyone else to the birth (and death) of the universe. Alok Jha is the science correspondent for ITV News. Before that, he did the same job at the Guardian for a decade. He has reported live from Antarctica and presented programmes for BBC TV and radio.

2 September 2015 There's been a trend recently for some eminent scientists to write off philosophy as a discipline which fails to meet the criteria for scientific enquiry. This is a bit of a puzzle for some philosophers, who didn't actually realise that they were supposed to be doing scientific enquiry in the first place. And anyway, say the philosophers smugly, these scientists are working with some pretty questionable epistemological principles. This is all quite sad, because science and philosophy are both brilliant and they'd both be even more brilliant if they could talk like grown-ups. But at some point, too many philosophers and scientists seem to have just stopped listening to each other. In response to this problem, this lecture is one of a pair (the other one being 'Why philosophers should listen to scientists') which are intended to get a better dialogue going between the two disciplines than has existed of late. Charlie Duncan Saffrey is a philosopher, writer and stand-up comedian who has studied at the universities of Liverpool, Warwick and Sussex, and this year he is a visiting lecturer at the University of Westminster. He is the founder and host of 'Stand-up Philosophy', a live philosophy night which brings comedians, philosophers and experts together to answer philosophical problems. He lives in East London with some actors and a small collection of seashells.

10 June 2015 The media love to sensationalise the dangers of illicit drug use, whilst downplaying or even ignoring the harms from legal drugs. Suzi takes us on a trip through the current scientific understanding of the harms, and also potential benefits of recreational drugs, both illegal and legal. Dr Suzi Gage is an Epidemiologist at the University of Bristol, investigating associations between substance use and mental health. When not staring at spreadsheets full of ones and zeros she writes the Sifting the Evidence blog on the Guardian website, and has a small obsession with synthesizers.

2 September 2014 This isn't just a simple talk; it's a call to arms. Every day, we hear claims about what is good for our health, bad for the environment, how to improve education, cut crime, and treat disease. Some are based on reliable evidence and scientific rigour. Many are not. These claims can't be regulated; every time one is debunked another pops up – like a game of whack-a-mole. So how can we make companies, politicians, commentators and official bodies accountable for the claims they make? If they want us to vote for them, believe them, or buy their products, then we should ask them for evidence, as consumers, patients, voters and citizens. The Ask for Evidence campaign has seen people ask a retail chain for the evidence behind its MRSA resistant pyjamas; ask a juice bar for the evidence behind wheatgrass detox claims; ask the health department about rules for Viagra prescriptions; ask for the studies behind treatments for Crohn's disease, and hundreds more. As a result, claims are being withdrawn and bodies held to account. This is geeks, working with the public, to park their tanks on the lawn of those who seek to influence us. And it's starting to work. Come and hear what the campaign is going to do next and how you can get involved.

22 July 2015 Homeopathy is one of the most widely debunked forms of alternative medicine – yet homeopathic remedies adorn the shelves of respected pharmacies and are funded by taxpayers on the NHS. How big of a problem is this? Using information and personal experiences gathered during his last 6 years of campaigning against homeopathy, Michael Marshall will highlight how much money is spent on homeopathic remedies, how this gives undeserved credibility to homeopathy, how such remedies can lead to genuine harm and what you can do to help. Michael Marshall is the Project Director of the Good Thinking Society and the Vice President of the Merseyside Skeptics Society. He regularly speaks with proponents of pseudoscience for the Be Reasonable podcast. His work has seen him organising international homeopathy protests and co-founding the popular QED conference. He has written for the Guardian, The Times and New Statesman.

6 May 2015 From developing theories and defining natural laws, science is a human construct. How does it work? What can it solve? How do you think science works? What does being a scientist mean to you? Dr Sylvia McLain talks about the history of science and its culture and the rise and fall of theories and laws and discusses what science means to us in the modern age. Dr Sylvia McLain is a biophysicist at the University of Oxford, runs a research group in the Biochemistry Department and teaches at St. Peter's College. She has an undergraduate degree in Zoology, a Masters in Education and a PhD in Chemistry. She is a failed house cleaner and fast-food server, and spends her spare time reading far too much and being altogether far too opinionated.

14 January 2015 Science and medicine have transformed our lives immeasurably, and never in history have they been more central to our lives and well-being. Yet despite this, there is often a glaring disconnect between the findings of actual science and media reporting of such topics, and consequently there is often a needless chasm between public perception and the evidence on many contentious topics. This can lead to needlessly adversarial and counter-productive discourse of everything from vaccination to climate-change. In this talk, physicist and science journalist Dr. David Robert Grimes discusses the frequent problems in reporting science from misunderstandings to bad statistics to false balance, and discusses the factors that influence this and how such problems can be remedied. Dr. David Robert Grimes (@drg1985) is a physicist and writes regular opinion and analysis pieces on scientific issues for the Irish Times and the Guardian science, and is a regular panelist on science issues on radio and television. He is joint-recipient of the 2014 Maddox Prize for Standing up for Science.

1 October 2014 The James Webb Space Telescope, a collaboration between space agencies in the US, Europe and Canada, will succeed the Hubble Space Telescope as the foremost space telescope in 2018. Its unprecedented size, sensitivity and suite of instruments will revolutionise our view on the Universe, from showing us how the very first galaxies formed to revealing the atmospheres of planets outside our own solar system, where life may be forming. Sarah Kendrew will give an overview of the mission and the exciting science it will do after launch. She'll talk about where the mission is right now, from her personal involvement in one of JWST's 4 instruments, MIRI. Sarah Kendrew is an astronomer at the University of Oxford. She works on optical and infrared instrumentation for the observatories of the future, and researches how stars form in the Milky Way Galaxy.

2 July 2014 The Alpha Course runs in 162 countries and has been attended, according to their website, by 25 Million people. Over a 9 week period, students are guided through Christian theology ostensibly to “Explore the meaning of Life”. Simon Clare, an unabashed atheist, signed up to his local course in Brighton, wondering if his faithlessness would be challenged. Spoiler: He wasn't converted but he was surprised at what he learnt about faith. The new Archbishop Of Canterbury, Justin Welby, found his faith at the home of the Alpha Course and his election suggests that the Alpha model of spreading the word is now at the heart of Christianity's struggle for survival. As well as giving an overview of the course from biblical history to singing in tongues, Simon will discuss what atheists can learn from the Alpha Course. Simon Clare runs Horsham Skeptics in the Pub and is a founder member of the South East Skeptics Society.
