Have you ever wondered what is the driest place in the world or how to put a pear in a bottle? The results of recent scientific discoveries will help us better understand some of the interesting things in life.

Interesting discoveries surprise you

all the creatures like sugar?

Is not. The taste depends on the diet of each animal. The less the opportunity to eat sugar, the less animals like sugar. Only animals that regularly eat fruits like monkeys, gibbons, foxes, hummingbirds . are really addicted to sugar. Omnivorous species such as bears, wild boars, rats . will not be bile or ripe fruit.

Dogs are another case. Because there are ' relatives ' with wolves, dogs love to eat meat but do not refuse to eat fruit, if there is nothing else to eat. Live carnivores like tigers or lions do not love sugar. Cats do, too, but when licking a cold ice cream, it is the smell of milk that attracts it, not sugar.

Where is the driest place on Earth?

Two scrambled desert this title. It is the Atacama desert north of Chile, and the valley of McMurdo bay in Antarctica. The average annual rainfall in the world is 15mm, but there are some areas that almost never receive rain or snow. The dryness of the Atacama is due to the location between the Andes in the east, blocking the clouds and another mountain range of the west coast that does not allow Pacific mist to enter. And the Antarctic valley rarely has snow because the cold wind blows along the ice toward the coast to dry the air on its way. Atacama has dried up for the past 20 million years, the valleys of Antarctica have dried up 10 million years ago!

Artificial gravitational force?

There are many methods to create gravity like Earth's gravity . First technique: push the ship with a continuous acceleration of 10m / s. Passengers will be glued to the deck like the kind of force that sticks us into the seat when long-haul aircraft take off. Second technique: use centrifugal force .

In space, just turn a cylindrical ship around its axis as a passenger that can be fastened to the inside of the ship. It is also the force that makes clothes stick to the rotating drum of the drying unit in the washing machine.

What about therapy with light?

Light is used to treat biological rhythm disorders. The most common is seasonal debilitating (appearing before and after the winter solstice is the shortest day with the least sunshine) or sleep disorders related to the time difference. Many activities in the body follow the cycle of the internal clock such as sleep cycle, body temperature, appetite, rate of hormone secretion . but still need external signals to operate synchronized. It is the natural light that passes through the eye into an electrical signal, helping the body to integrate into the day-night rhythm. Light therapy (compensating for the lack of sunlight) reproduces consistency, by letting patients sit under artificial light every day, with adjustable spectra and intensity.

Can boiled water be drinkable?

It is not always possible to drink. If a few minutes boil enough to kill most mold, toxic algae and viruses, but some germs (such as streptocoque .) survive for more than an hour in boiling water 120 ^° C. And right at this temperature It is also not certain that neutralizing certain pathogens like clostridium botulinum can cause fatal poisoning. Some other poisonous mushrooms have resistance to 250 ^o C. And boiling has no effect on chemical toxins.

Is there a ' painful ladder '?

No and yes. Because pain cannot be measured absolutely like hearing or seeing. Moreover, the feeling of different types of pain, as well as the intensity, depends on the feelings of each person. However, health experts still create an empirical pain ranking system.

The patient then indicates the level of pain on a scale or answers a series of questions to determine the level of pain. When the patient is unable to describe, the doctor assesses the level of pain depending on the degree of facial contortions or distortion.

How to put a pear inside the bottle?

The bottle was blown into a shape around the pear? - I do have it!

In fact, people put pears in a bottle when the pears are tiny. This method protects the pears from being deep and also applies to many other fruits such as apples, grapes, plums .

If the Moon disappears?

Initially only the coastal people knew of this change: there was no big wave because there was no attraction of the Moon, the tide remained active (the Sun's impact) but decreased by two thirds of its power.

The moon helps maintain 23 degrees of tilt on the Earth's axis, and thus has consecutive seasons. When there is no Moon, the Earth may tilt 85 degrees for several hundred million years. Such messy movements will greatly affect the distribution and survival of living species.

Why are dark circles under the eyes?

Because blood flow is not good in veins around the eyes. Fatigue, alcohol consumption, improper hygiene can cause blood vessels to circulate red blood cells in clusters. At that time, dark red color accumulates under the eyes and is visible because the skin is very thin.

And the wrinkles around the eyes are caused by a lack of collagene - a fiber protein that ensures skin elasticity. With fatigue, cell activity decreases in the epidermis, leading to a decrease in the amount of collagens. See more clearly with thin skin under eyelids.

Which is the most stable substance in the universe?

Iron. At the formation stage, stars form helium gas from the melting of hydrogen nuclei. When depleted, helium reacts with carbon and oxygen. Melting continues and produces chlorine, potassium, calcium, titanium, silicium . to iron. And when only iron is left, the star fades because the molten iron with other atoms requires energy, but why not have the energy to supply. This transformation process will stop at iron and cause a new star explosion (supernova).
