Hi Dear Followers,

How are you? Are you following the Olympic games ? Maybe you are in Rio watching and participating live. In any case, I wish you a nice time. I like watching athletism…Let's see what Usain Bolt will do in the 100 m and 200 m.

Let me know what are your favorite sport watching or doing. I would love to know!

This Olympic mood inspired me to write about a study from the University of Cardiff. A team led by Professor Roger Whitaker showed that the large human brain is a result of constantly sizing up each other.

Their study was focus on cooperation. It is a fundamental human trait and they were to understand more about it.

The team proposed that evolution favors those who prefer to help out others who are at least as successful as themselves.

The study was made by computer scientists and I must admit it is not my strong suit. As a molecular/ cellular/ biochemist, I find this research project interesting for social purposes.

On way of sizing up each other is sport. Could sport competition be a important activity to increase our collective brain size ?

You can read more on the article in Scientific Reports. Let me know what you think.

We can always learn :)
