Stuffed crackers are as addictive as cocaine, scientists say

A study conducted in the United States compared the reaction of rats to ingestion of Oreo crackers and drugs such as cocaine and morphine. The wafer was used in the study to test the effect of high calorie foods with high sugar concentration. Neuroscience professor Joseph Schroeder and some of his students have found that eating Oreo, one of the most famous stuffed crackers in the United States, can activate more neurons in the pleasure-associated brain region than taking drugs.

With the dominance of the use of fire and the great growth of their populations, man began to increase the frequency of burnings in these environments, as well as changing the time of occurrence of natural burns.

Some common forces in nature

Force weight It is the force with which the earth attracts the bodies. When a body is in free fall, it increases approximately 10 m / s every second. As we have seen, the magnitude that measures the variation in body velocity as time goes by is acceleration. We have seen that the acceleration of gravity has a value of: The value of the acceleration of gravity is not the same for all the stars in the universe.

Thermal inversion

An interesting phenomenon in the atmosphere is that of thermal inversion, when the action of air pollutants can be greatly aggravated. It works like this: Normally, the air near the ground surface is in constant vertical movement due to the convective process (convection currents). Solar radiation heats the surface of the ground, which in turn heats the air that bathes it; This hot air is less dense than cold air, so hot air rises (upward vertical movement) and denser cold air goes down (vertical downward movement).

Histology

Histology (from Greek: hydton = tissue + logos = studies) is the science that studies biological tissues, from their formation (origin), structure (differentiated cell types) and functioning. But what is fabric? The body of a multicellular organism is made up of different cell types that specialize in performing various functions.
