Welcome to Eastbourne Sceptics in the Pub.
At Sceptics in the Pub local and national experts in their field present and then discuss a topic in a friendly and relaxed environment...a pub!
The common theme for all the talks is scepticism (or skepticism if you prefer), which in broad terms means bringing a scientific, evidence based approach to examine common beliefs and misconceptions. You can find out more about skeptics here.
We charge £3.00 for tickets to cover running costs and speakers travel expenses. Tickets go on sale online (with an additional booking fee) a few weeks before the next event or may be purchased at the door on the night.
We hope you will come and have a drink with us.

What's the talk about?
Modern biology is rewriting our understanding of genetics, disease and inheritance.
There are lots of situations where two things that are the same at the DNA level are different in appearance and behaviour. These tell us that there is more to life than just the genetic code, and they are known as epigenetic phenomena.
Think of a caterpillar and a butterfly, or a slipper limpet that can change its sex as an adult shellfish. Identical twins become more dissimilar as they age, despite sharing an identical DNA script. The differences can even be as extreme as one twin developing a serious disease while the other remains completely healthy.
Scientists are starting to understand how these epigenetic differences are created and maintained. The process depends on a complex set of chemicals that our cells add to our genes. These chemical changes controls how genes are expressed, so that the same genetic code can create different outcomes. They can also have unexpected effects.
For example, epigenetics is very significant to human health and disease and may have a role in a wide range of conditions from chronic diseases such as rheumatoid arthritis and schizophrenia, to drug addiction and to the long term effects of abusive or neglectful childhoods. It is also known to be important in cancer.
Sometimes, epigenetic effects may even be passed on from parent to child. Children born to mothers who have lived through starvation may have increased susceptibilities to various diseases later in life. Animal studies have suggested that fear itself may be passed down to offspring.
