Mathematicians Reveal Eating Behavior Bees


Mathematicians of the Queen Mary School of Mathematical Sience, Rainer Klages and Lars Chittka of the School of Biological and Chemical Science, UK revealed that bees have a unique fly patterns.

Both scientists are observing the behavior of bees while foraging. The results were published in the journal Physical Review Letters this month.

Bees are known to have visited some flower nectar. Occasionally visited by some direct interest to get it. Researchers tested how predators influence such behavior.

"In mathematics, we treat the bees as random objects moving toward the target which is also distributed at random," Klages said as quoted by the site Physorg, Friday (03/02/2012) then.

Snake scales


Scales is key to the snakes in a move that can prevent slipping while on slippery surfaces. Hamid concluded Marvi, a biologist from the Georgia Institute of Technology in Atlanta, USA, after doing research tekait functions snake scales.

In the first experiment, Marvi anesthetize snakes are moving and tilting motion of the surface so that the snake fell off. Meanwhile, a second experiment, Marvi disturb the snake's motion to be dropped without him sedated.

In each experiment, Marvi measure the angle and the coefficient of friction is created between the scales and the surface motion. The results showed that the coefficient of friction when the serpent realized 2-fold greater than when anesthetized snakes.

"When the snake did not realize, no controls, no response, no sensory system. But when the snake came to, he could feel. I'm moving so I had to do something. There is an active mechanism involved," said Marvi told New Scientist , Friday (03/02/2012).
