Topic 42: Things Humans Do and Scientists dont know why

Scientists work hard to find out everything humanly possible. They want to know why the sky is blue and why we cant understand animals, they want and need to know EVERYTHING! but that’s just not possible. There are many things that scientists don’t know and its possible that they will never know. Some of the things they don’t know is about our own bodies and minds and behaviour…

1. Blushing: There are many theories of why we humans blush. Sure it can be out of embarrassment, to cool the brain down, too much blood of in your head…but, some people can actually make themselves blush.

2. Dreams: Dreaming is fun but besides theories no one actually knows why we dream. There are many theories to cover the purpose of this phenomenon and there has been tonnes of research but they just don’t know…yet.

3. Kissing: Sure it can be gross and fun and affectionate and, well, yeah. But its not in our genes to have the need to kiss, it is thought to be an emotional need.

4. Genes: Scientists know that we have genes and why we have them, where they came from, the chemical formula, scientists know everything about them…except, why we have as many as we do. When the human genome project was completed it was expected for us to have about 50,000 and 140,000 genes, but in reality we have between 20,000 and 30,000. That might sound like a lot but its less than a grape or a tomato.

5. Consciousness: Scientists are able to explain what it is but they cant explain where is comes from. They study our brains and bodies as two spate groups then link them up to find a conclusion. The neurons in our brains are always moving and keeping us alive so where does it exactly come from…

6. Memories: We all have memories whether we like it or not but how do we access these memories.

7. Perception: It is the way we turn senses e.g. sight, smell, sound and taste into interpretation and perceive information. How does it work? scientists are really stumped on this one…

8. Movement and Reaction: Scientist understand how we move and why we move and react the way we do but how come we can do it so well?

9. Brains making the future: How can we predict the future and it comes true? How can we know what is going to happen?

10. Time: How is time represented in your brain? For example, click your fingers in front of your face. We see it in ‘slow motion’ in reality that just happened at 30 milliseconds faster than you can see.
