Nature - Fruit fly uses calculus, or something like in its mental calculation. Oh, the Math co-processor is in its wings

It is not just the discovery, I was also amazed at the techniques used by scientists in the experiment.

According to the article:- 

Neurons near the wings, part of what is called the haltere circuit, do the computations and send signals to the wings to correct the problem.

 The wings of fruit flies beat about 250 times a second.Disturb a fly’s flight in an extreme way, Dr. Cohen said, and “within three wing beats that sucker has recovered completely.”

I did not know this - Fungus in our mouth that protects from other fungus

According to the Article:

A little-known fungus called Pichia lives in healthy mouths and may play an important role in protecting us from an infection caused by the harmful fungus Candida. 

The other fascinating thing is it was able to inhibit other fungus that causes disease," Ghannoum says, including Aspergillus and Fusarium.
