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.

Sans Forgetica – Font that improves memory

Sans Forgetica – Font that streamlines memory – Australian researchers from the RMIT University (Royal Melbourne Institute of Technology) have found that our brain reads the fonts that it already knows more quickly, such as Arial or Times New Roman. By which, however, it remembers less content contained in a given text. Therefore, in collaboration with ethologists, psychologists and professor of typography, they have developed a font that is harder to read. Sans Forgetica called it – which in translation means more or less “without forgetting”.
The letters have gaps, are slightly tilted to the left and are in contradiction with the typical way of reading. Deciphering them requires more effort from the brain. Which activates the gray cells and forces you to stop at each word for a little longer. It improves memory and allows you to learn about 7% more information!

Deadly plants – Which are the most poisonous

Deadly plants – Although some of them look completely harmless, they can contain a cocktail of toxic substances. Venom developed so that no one could prevent them from growing. Plant poisons have a different effect on the human body. They most often attack the nervous system, respiratory organs, heart, liver, digestive system or kidneys. They can also affect muscle function, cause brain damage and even lead to death.

List of the most poisonous plants:

VR may cause vomiting – Because of motion sickness

VR may cause vomiting – Because of motion sickness – In order to fully enter the virtual reality,
one has to deceive not only the eyes but also the other senses. This is also the reason why
many virtual reality users can cause problems with motion sickness. Then the impressions
received by the liar do not agree with the visual stimulus. In motion sickness,
the eyes see that the body is not moving, and that the labyrinth registers continuous motion,
tilting and acceleration, in the case of nausea caused by virtual reality is quite the opposite.
Eyes see the perfect simulation of space, covering the entire field of view.
However, the brain does not record any motion signals from the labyrinth or other senses.
In both cases there is a sensual dissonance that causes malaise, dizziness, fatigue,
and even vomiting.

Old age mental activity – Number of neurons

Old age mental activity – number of neurons

Old age mental activity – number of neurons – The decrease in mental activity in old age
was attributed to the decreasing with age, the number of brain cells.
Neurologists from universities in Boston and Washington, however, proved.
That almost all of the 10 billion cells used while thinking, they are active even in 80-year-olds.

Alcoholism effects – Repairing damaged neurons

Alcoholism effects – repairing damaged neurons – Scientists from Wurzburg in Germany
found that damage to brain cells caused by excessive alcohol consumption can be repaired only partially.
They note that in the interest of alcoholics is the fastest return to sobriety. Longer heavy drinking
causes brain regeneration proceeds with great difficulty.

Impact hair thinking – Hair arranged in the left side

Impact hair thinking – Hair arranged in the left side – Researchers from the University of Bonn
have discovered that only a small part of the population. Hair around the crown arranged to the left.
They proved that the hair arranged in the left side may have a similar effect on the functioning of the brain
as writing with left hand. Thus confirming the theory that describes the stacking of hair left
almost exclusively left-handed persons.

Men and women brains weight differences

Men and women brains weight differences – Researchers under the direction of Paul Farmer
of Harvard Medical School in the US have shown that the size of certain parts of the brain in women
is different from the same part of the brain in men. The frontal lobe in which the center of
decision-making and problem-solving, weighs more in women than in men. More space is also an area responsible for short-term memory and spatial orientation.

Physical exercises beneficial effects

Physical exercises beneficial effects – Have a positive impact on the level of neurotrophic factor BDNF,
which promotes growth, improves communication and survival of neurons. A diet rich in healthy fats,
for example. Omega-3 fatty acid, nourishes the brain tissue, where fat plays a key role – creates
a sheath cellular and myelin.

Brain Map – Computer atlas of the biochemistry

Brain Map – American scientists have provided online computer atlas of the human brain. The project cost approx. $ 55 million. During the development of the atlas was examined and mapped the biochemistry of two brains of adults. With the obtained data it shows that human brains combines 94% rotation-similarity. Atlas is similar to the multi-purpose GPS system – the brain identifies landmarks in 1000 based on over 100 million data points each biochemistry and genes that reveal in it. Atlas is available at www.brain-map.org.
