Naked mole-rat – Heterocephalus glaber

Naked mole-rat – Heterocephalus glaber – Is practically blind and has no pain. This rodent lives in East Africa. It is digging underground corridors in search of tubers and roots. For this he uses the incisors that are in front of the lips, so that the soil does not get into the mouth.
Mole-rats spend almost their entire lives underground without going to the surface. They are unusual for many reasons. Not only are they the only cold-blooded mammals, they are also resistant to cancer, aging, hypoxia and pain.
Their almost completely hairless, thick and wrinkled skin. It is insensitive to abrasions or scratches. Because Mole-rats do not have the key neurotransmitter for pain conduction (substance P).

Naked mole-rats are the longest-living rodents (they live to 30 years)

And their risk of death doesn’t increase with age. These animals have very active mechanisms repair DNA.
They also tolerate extreme hypoxia, which often occurs in narrow and stuffy underground tunnels. When there is a lack of air, mole-rats reduce life activity. They change the energy supply process (break down fructose instead of glucose). In this way they avoid brain damage.
The equally interesting is structure Social. Which resembles swarms of bees or ant colonies. Flocks of these rodents count from several dozen to 300 individuals. At the same time, only the queen and prolific male breeds. The rest are sterile and conscientiously work for the herd.

Chinese see otherwise

Chinese see otherwise – A study by Rachel E. Jack from the University of Glasgow, on 15 white Europeans and 15 Chinese people showed that the Chinese in assessing the emotions of another human being focus on the expression of the eyes, and the Europeans are looking primarily for eyebrows and lips caller. These cultural differences lead to erroneous read emotions and misunderstandings between members of different cultures.

Ig Nobel Prize – Humorous parody

Ig Nobel Prize – Known as Anti Nobel Prize is a humorous parody of the Nobel Prize. It is obtained for extraordinary, unnecessary research or inventions. In 2015. Anti Nobel in the form of pots received the study of pain we feel after being bitten by insects. It turned out that the most vulnerable places are the lips, penis and nostril. In the field of physics Anti Nobel received an international team for the length of urinating in different mammals. According to experts, the size of the animal does not matter, almost all mammals empty their bladder in approx. 21 seconds.
