When we imagine lunar colonies, they mimic cities in a small scale and have sweeping vistas that include the Earth hanging above the horizon, but, that’s a great way to get cancer super fast since we still don’t know how to protect ourselves from cosmic radiation.

Is Happiness Actually Contagious?

When Jess Phoenix, geologist and Congressional candidate, fell in love with studying volcanoes, she began trekking all over the world to watch them erupt.“If you’re a volcanologist, you want to be there when everyone else is running away,” she explains.

Does Your Brain Force You To Stereotype?

This week, we are covering stereotypes: why do they exist, why does it seem so hard to get rid of them, and how did they become such a big part of who we are? For the first episode of this five-part series, Trace will be discussing: does our brain force us to stereotype? Stereotyping is actually something our brains are constantly unconsciously doing. Obviously, making sweeping generalizations is a bad thing to do. But what the brain initially intended stereotyping to be was a way to help us interact socially in a more efficient manner. Our brain developed a filing system to store pretty much anything we absorb (whether it is true or not) into similarities. Everything that can be viewed, heard, read, smelled, tasted, or touched is interpreted first through the temporal lobe of our brains, which processes sensory input into meaning. Then it moves to the anterior temporal lobe, which stores knowledge about people and social groups. From there, it movies to the dorsal medial prefrontal cortex, which supports the formation of impressions which are then used in the inferior frontal gyrus, which decides if the situation is safe or not. As this complex pattern bounces around inside our brain, we make predictions in ways that are supposed to make us comfortable in the world. Stereotyping is merely a byproduct of this system; they're essentially "brain shortcuts" that help us conserve energy. We don't just do this with people, either: we do it with objects, too. When we see a fork, for example, can tell what it's made of, what it feels like, and what its purpose is... without even touching it. Imagine how tedious it would be if you had to learn what a fork was every time you sat down for a meal? Unfortunately, brain didn't take into consideration is that--unlike utensils--categorizing people can hurt people's feelings. Do you think you don't stereotype? Chances are that you do. Trace explains why. <a href="http://testtube.com/testtubeplus/">TestTube Plus</a> is built for enthusiastic science fans seeking out comprehensive conversations on the geeky topics they love.
