Stirring soup with a fly swatter sounds disgusting, but why do our brains think so?
Just in time for Halloween, teens are invited to get grossed out at an upcoming Teen Science Caf茅 at 抖阴短视频 Boulder that explores the science of what happens in the brain to trigger reactions of disgust.
鈥淓www Disgusting! The Evolution and Neuroscience of Getting Grossed Out鈥� to be held Tuesday evening will include a lecture, touching and tasting stations, and other hands-on activities.听Karli Carston, a research associate from the Institute of Cognitive Science, will dig into the topic of what鈥檚 gross and why. The event, run by 抖阴短视频 Science Discovery, is free and open to teens ages 14 to 18.听
According to Carston, disgust is a biological mechanism that allows animals to avoid harmful toxins and pathogens, and also has a social, cultural and moral dimension.

In humans, the expression of disgust is recognizable from the wrinkled nose and protruding tongue, and we use these signals to learn what sort of things to avoid. Thus, what is a delicacy in one culture can be disgusting to another. Social and moral disgust also serve to reinforce social norms. Disgust provides a foundation for human morality by providing the emotional impetus to avoid certain behaviors,鈥� Carston explained.
The Teen Science Caf茅 is part of a national push to get more young people interested in science, technology, engineering and math (STEM) subjects. 抖阴短视频 Science Discovery, a STEM education outreach program, started offering science caf茅s to Colorado teenagers in 2013 as a way for them to meet and interact with 抖阴短视频 Boulder scientists in fun and informal settings.
鈥淭een Science Caf茅s provide a unique opportunity for teens to explore current STEM topics and interact with scientists and engineers in a relaxed social setting,鈥� said Stacey Forsyth, director of 抖阴短视频 Science Discovery. 鈥淭eens play an active role in managing the caf茅s, by selecting featured topics and scientists and designing cafe programs, and we try to expose students to topics they might not normally encounter in a traditional high school science class.鈥�
