 Most people in the world dream of equality and justice. Let’s see what each of us will get if everything is divided equally. 2 liters of petroleum per day for one person 177 grams of wool 21 centimeters of railway track 1018 centimeters of roads 100 bananas 56.6 kilograms of cardboard and paper 36.9 kilograms of meat 23.3 grams of gold 269 grams of soap 107 kilograms of wheat 808 cigarettes per year for one person 1125 grams of coffee 4 liters of pure alcohol 2 condoms 25.8 kilograms of mineral fertilizers 5.63 kilograms of magazines And the worst part is, 738 discarded plastic bags.

How does alcohol effect on human DNA?

Изображение
English scientists determined that acetic aldehyde, which is the byproduct of ethanol fission in the body, can cause permanent damage of DNA. Also, it was shown that cells have two mechanisms which protect them from the ravages of acetaldehyde.  Due to special enzymes the toxin splits out, but if it’s not enough and acetaldehyde, by accumulating, begins to damage DNA, the second mechanism takes effect and recovers DNA thanks to Fanconi anemia proteins. But if there are not enough Fanconi proteins in the body, an organism, including DNA, suffers permanent damage.  The same thing happened when alcohol was tried on pregnant mice. It’s a proof of the fact that drinking is capable of leading to the accumulation of such a large amount of acetaldehyde that it’s enough for the disruption of protection mechanisms.  The data obtained calls for a fresh look at the mechanisms due to which alcohol has a devastating effect on an organism.  That’s why alcohol consumption gives rise

Facts that you probably don't know

5 little-known but very interesting scientific facts: 1) It turns out that not only birds build nests. Gorillas do that, too. They make nests of curved branches and soft foliage and sleep in them. 2) Red juice which comes out of steak while frying it actually isn’t blood, but myoglobin, so to speak, the close relative of blood. When steak appears on the counter of a supermarket, it doesn’t comprise even a drop of blood. 3) As a rule, the wool of household pets doesn’t become the reason of allergy. It is usually caused by their saliva or the particles of dead skin. If you wash your pets more often, your allergy will disappear. 4) When you hold a sea shell to your ear, you think that you can hear the waves of the sea, but in fact, you listen to the noise of blood running through your veins. You can also do that thing with the help of an ordinary teacup. 5) Dolphins don’t drink water. They meet their need for the liquid through food which they eat. As you can see, there are a

A notebook from the future

“Plantbook” probably can be called the most unusual concept of notebook. Its creators are Koreans named Hyerim Kim as well as Seunggi Baek. They astonished the world of technologies by their imagination.  Their “Plantbook” has a flexible display and touch-sensitive keyboard and it can form a tube! It can be charged, using both solar energy and water. It sounds unbelievable, but in addition this gadget produces oxygen! There is a green loop in the form of a leaf at one end of the notebook which displays a battery level.  A lot of investors have already been interested in this device, since it’s not only the first promising fashionable up-to-date technology but it’s also intended to concern about nature and its ecology.

The lightest material in the world

This material is a novelty in the world of modern technologies. Its creators are the researchers of Zhejiang University (China). This material was given the name graphene aerogel.  The world of science was impressed by both appearance and characteristics of the aerogel, since it has extremely low density which is 16 milligrams per cubic centimeter.  You can easily place quite a big piece of this unique material on the surface the petals of a flower.  The graphene aerogel can absorb different liquids at high speed like a sponge. It’s quite possible that precisely this material will be used to pick up oil spills in the future.

Why do some people get bitten by mosquitoes more frequently than others?

The color is clothing  As it turns out, mosquitoes closely follow fashion trends and prefer to fly towards people wearing the clothes of a certain color. Of course, with regard to fashion, it was a joke, but these insects are really attracted by people wearing dark clothes.  Movements  If you actively move and wave your hands, you don’t keep insects away and, in contrast, intensively attract them. Body heat Mosquitoes pick up even slight difference in body heat and bite the warmest man. It appears that you will draw more attention to your body after physical training. Also, pregnant women and sick people whose temperature is above normal are usually at risk.  Carbon dioxide  Mosquitoes can detect the source of carbon dioxide at a distance of 50 meters. For example, pregnant women breathe out 21% more carbon dioxide than other people. Children, on the contrary, will attract these insects not so much, since they exhale less carbon dioxide than adults.  Alcohol
