Researchers found that lab rats are willing to help set their partner free

If you had to choose between helping a tortured friend out of their misery & getting 1 million dollar all for yourself, which one would you choose? We all know that a lot of people out there will choose money.

However, Inbal Ben-Ami Bartal from the University of Chicago had discovered that rats are able to learn and willing to set-free their cage-mate. And unlike most human, this rat seems willing to help even when it got nothing in return.

The researcher even try to distract the rat by using chocolate but the rat still keep it focus to save the trapped cage mate.

However, lab rats helping each other weren’t actually a new discovery. Back in 1959, Russell Church, a psychologist had train a rat to press a lever to get food. The psychologist then connects the lever to another cage that contains another rat.

If the first rat pushes the lever, it will get the food but the rat in the other cage will get a painful electrical shock. What happen next is amazing, after realizing that the lever that it push will cause painful electrical shock to the other rat, the first rat simply avoid the lever.

Russell Church then published his discovery in a paper called “Emotional reactions of rats to the pain of others”.

In 2006, Dale Langford from McGill University had made another similar research and she gets more evident that rats feel empathy.

What she did is she put a couple of rats together for two weeks before separating them. One of the rats is puts inside of a cage, and the other rat is outside of the cage. The rat can free his trapped partner by pushing against a restraining door and tipping it over. After about a week of learning how to do that, the rat successfully set his partner free.

These two experiment show that rat can feel empathy and willing to take action to help each other.

How real-life samurai warrior look like

After watching some samurai films, I figure you might be interested in knowing how a real-life samurai warrior actually look like. So here are some pictures of them. From these pictures, we can see that they not only use sword as their weapon, but also bow and some sort of customized spear. I personally think the real-life samurai warrior didn't look as cool as the one in the movies. But they do look brave and strong tho.
