Crowd Psychology

The next Science Cafe event in Bangor (at the Fat Cat Cafe) takes place on 2nd July and features a talk by Dr Clifford Stott of the University of Liverpool in which he explores the psychology of crowds with a focus on football crowds, having been studying the phenomenon since the 1990 World Cup, and having worked with police during Euro 2004.

Pulling Faces

Not all of us are capable of pulling a full range of facial expressions. A new study led by Dr Bridget Waller of the University of Portsmouth has found that certain muscles, particularly relating to the more extreme expressions, only appear in the faces of part of the population. Dr Waller discusses the study and also how our faces compare with those of the apes.

Genetics in Merthyr

Our reporter Paul Morris visits Merthyr to find out more about the GAMY project (Genetics And Merthyr Youth) which is promoting a better understanding of our genes to the younger generation.

Null Hypothesis

Adam discusses some of the "unlikely science" with Andrew Impey from Null Hypothesis - some of the science that creeps under the radar.
