Have you ever that yawning has yet to be scientifically explained? WELL NOT ANYMORE!!! Today, scientists cracked the code of the mythical yawn. As you all may very well know (I’m talking to those late night studying students or workaholics) yawning is associated with sleep or boredom. However, you may not know that yawning may also be done in the anticipation of important things or stress. And I’m just here to say that some people think that yawning takes in more oxygen, however that is quite untrue.
OKAY. The new part is that scientists have performed research which points towards the belief that yawning is to “cool” the brain. Basically, taking that huge gulp of air helps to regulate the temperature in your brain. Scientists also discovered a pattern which supports this hypothesis. They did their research in Arizona and Vienna, where scientists recorded the amount of people yawning in the summer and winter. It turns out that yawning occurred much more frequently in temperatures around 20 degrees Celsius. This then shows that people tend to yawn in certain temperatures. I never really noticed it myself, but I do tend to yawn a lot more in than winter than when I’m kicking my sheets around on a hot summer night.
We’re talking about this literally. There isn’t really any science to help you guys if you’re going through some hard times. Sorry.
ANYWAY! Let’s talk about what scientists have done recently! These guys have now successfully engineered tissue which beats, just like hearts. This has been done, not only in labs, but has been implanted in animals as well. So with this wonderful new technology, millions of people with heart problems could seek successful treatment.
Trick is, like MOST research, it is not completely yet and does not completely resemble the human heart. Early versions of this tissue fell apart where as human heart tissue is elastic. It simply just isn’t as easy as sticking on more tissue to a heart like we do with skin. Hopefully, in the future scientists combine whatever technology they have to complete this method of heart transplanting.
I’ve been watching quite a bit of Brain Games lately, on National Geographic. That is some wacky trippy stuff man!
