9 latest discoveries about people

Although we have studied ourselves for thousands of years, we cannot know everything. Development science will help us unravel the mysteries of the body, intellect and human culture.

Adults have brown fat of children

Scientists have long believed that brown fat is found in children - helping to produce heat to keep them warm, will disappear as they grow. But a new study published this year in the New England Journal of Medicine demonstrates that many adults still retain children's brown fat.

This substance is good fat because it burns calories. On the other hand, researchers also found that leaner people often have more brown fat - which helps to regulate body weight better. Increasing the production of brown fat may be a new way of treating obesity.

Your skin is full of bacteria

Through the Human Biometrics Project (HPM), scientists are increasingly aware of the many bacteria that inhabit our bodies.

New research results show that there are many types of bacteria that live in different areas of our skin and have different types. The forearm is the place that contains the most types of bacteria - about 44 different types .

People who stay up late awake more than those who wake up early

Early morning people - can step out the door earlier, but at a price: they may not focus as long as people who sleep late.

The study measured the alertness of two sleeping groups after 22:30 and 1:30. The results showed that both groups had the same attention early in the morning, but late sleepers showed more concentration than early risers after 10:30. So if you wake up early naturally when dawn has just arrived, you should think twice before booking an important appointment at noon.

Can you speak into my right ear?

If you want to ask someone to do something, it might be better to say it in their right ear, instead of the left ear - a study has suggested.

Research shows that people are more focused on their right ears, so what is said is likely to be heard more by listeners. This may be due to the factor: the speech that enters the right ear is analyzed by the left brain - which is the hemisphere of the brain that processes the information expressed by words.

If you want to ask someone something, it is better to say in their right ear.

Doing many things at once can slow you down

People who do many things at a time often deal with worse jobs if they do each job independently. Research shows that people who do many things at a time will take more time, and when they want to switch between tasks, they take more time at that point.

The study also points out a lot of evidence for the discussion of certain circumstances, such as texting while driving, is really unwise, even dangerous.

Young cries are mother tongue

Even if the child is only a few days old, their cries are similar to their native language - researchers in Germany have discovered this.

For example, the cry of a French child has a higher and higher tone from the beginning to the end - a characteristic of the French language. As for the cries of children in Germany, it often starts with a distinct sound pattern of the German language.

Most young children lack vitamin D

A national study in the US showed that about 70% of children do not have the necessary amount of Vitamin D - this is indeed a shock. They blame poor diets with less vitamins and lack of sunshine.

Vitamin D deficiency can cause bone disorders such as rickets, or heart disease. So, a solution for the new year is: Let the children work more outdoors.

Living before marriage can lead to early divorce

Researchers at the University of Denver point out that living together before a formal marriage is not good. Study over 1,050 married people, 19% of them - had lived together before marriage, admitted to telling their spouses about divorce, while the group did not try to live before marriage. , only 10% ever thought of divorce.

The study also shows that people who try to live before the wedding often have a poor marriage.

Why can't we just go?

As we all know, there are many animals, such as horses or giraffes, when they are born, can teach themselves and walk after only a few hours, and humans take nearly a year to can stand on two legs.

One study showed that although some mammals seem to start walking at different stages in childhood, they actually only start at the same time the brain actually develops. So is man. It takes up to 9 months for humans to begin the biological cycle for walking, programming according to the gradual growth of the brain.
