Sun 28 February, 9:30am-6:00pm

Our huge weekender is back with a full double dose of fascinating science from a vast variety of fields. Where did HIV come from? Can psychedelic drugs cure depression? How do poisons work in the body? Experts present their research in the theatre alongside a venue-full of stands from top universities, giving you a chance to put professors in the hot seat and get practical with interactive demos.

FREE to enter the venue and visit the stands. Talks in the theatre £9 / £6 for a day pass online or cash on the door (see BIG SCIENCE SATURDAY for Saturday listings). Recommended ages 16+. Some talks will include topics of an adult nature.





28 Arsenic 10:15am Dr Kathryn Harkup: A is for Arsenic: The Poisons of Agatha Christie
Whodunit expert Agatha Christie used poison to bump off her characters more often 
than any other murder method – but how is it that some compounds prove so deadly in
such tiny amounts? Christie fan and chemist Dr Kathryn Harkup investigates the 
poisons the murderer used and how they kill.
 Dr Kathryn Harkup completed a doctorate on her favourite chemicals, phosphines, and went on to further 
postdoctoral research before realizing that talking, writing and demonstrating science appealed a bit more than
hours slaving over a hot fume-hood. / @rotwangsrobot
28 HIV 11:30am Professor Adam Eyre-Walker: The Origins of HIV
AIDS, the disease caused by the virus HIV, is still one of the most deadly human 
diseases. But where did it come from? Has it always been in humans, or did it just 
jump into humans from another species? Find out what we know about HIV and what it 
means to us. 
Professor Adam Eyre-Walker is an Evolutionary Biologist at the University of Sussex. He is particularly 
interested in evolution at the molecular level, how it occurs and what it can tell us about the organisms that 
DNA inhabits.
28 Bacon and Eggs 12:45pm University of Sussex, Genome Damage and Stability Centre: Bacon and 
Eggs: The Journey to Cancer
All humans start off from a single fertilised cell, which duplicates itself to create the 
many trillions of cells contained within an adult human. But sometimes the duplication 
goes wrong – and this can lead to cancer. Is it all doom and gloom? Hopefully not in 
this light-hearted exploration of the science of cancer.
 The Genome Damage and Stability Centre is part of the School of Life Sciences, University of Sussex.
2:00pm Steve Parker: Evolution: The Whole Story
Unfortunately Steve has had to withdraw for family reasons. So instead:
sp corner 2.00pm Very Short Introductions

Quick debate, sharp comment, rapier-swift riposte, needle wit: the art of debate is given a brush-up with targets John Haig, so-called probability pundit and Peter Coles, cosmology know-it-all, among others. So what if they have best-selling books published by Oxford University Press. Doesn’t stop the rest of us from tearing into them. Come and pick holes, or at least try.

28 psychoactive 72dpi 3:15pm Dr Robin Cahart-Harris & Prof Anil Seth: Psychedelics in Neuroscience 
and Medicine
New research using psychedelic drugs to understand the brain could lead to new 
treatments for mental disorders such as depression. Dr Robin Carhart-Harris will 
describe his research with these unusual compounds. @RobinCarhartHar
28 Cheats and Deceits 4:30pm  Martin Stevens: Nature’s Cheats and Deceits: How Animals and Plants 
Exploit One Another
It’s not just humans that will cheat and deceive each other given the chance – deceit 
exists across the natural world. From sneaky cuckoos to carnivorous plants, with a few fancy-dress insects thrown in for good measure, this is a journey into the subterfuge of 
the natural world. 
Martin Stevens is Associate Professor of Sensory and Evolutionary Ecology based in the Centre 
for Ecology and Conservation, University of Exeter. His research focuses on animal behaviour, coloration, and 
vision, across a wide range of animals, including fish, birds, insects, crabs, and primates. / @SensoryEcology


ALL DAY Cutting Edge: The Science Of Tooth Replacement
Many animals are able to continuously replace their teeth throughout life. This is achieved by populations of stem cells that reside in adult jaws. Adult human teeth also contain stem cells but rather than generating new teeth, these are required to repair tooth damage. Could these human tooth stem cells be used in some way as a source of cells to generate new teeth? From Kings College London.

The discovery of the Higgs Boson was a momentous occasion – but what’s next for the ATLAS experiment at the Large Hadron Collider? Discover how physicists are looking at matter on the smallest scale; delving deep into the secrets of dark matter and supersymmetry… From particle physics groups at University of Sussex, University of Birmingham and ICTP-Udine INFN. / ATLAS at CERN / @CERN
