New findings about the human body

For centuries, humans have not been able to confirm the discovery of the secret of the human body. And indeed, below are the 'shocking ' discoveries on the body that no one would have expected.

1. The face is full of . spiders

In 2014, scientists had a discovery of 'shock' when using large energy electron microscopes, enough to carefully examine every pore on the human face. They saw clearly the creatures as shown below.

These " spiders " are actually parasites Demodex brevis, living parasites in the sebaceous glands in the face pores . And according to the study, Demodex brevis is present on 100% of the participants.

The parasite has a very short life cycle, so they proliferate at an extremely fast rate , millions of individuals lay eggs and die. However, this also comes with an increase of sebum.

There have been many theories, many believe that rosacea - rosacea - a skin disease that causes skin rash and swelling may be caused by our immune system 'over-body' too much. This parasite species.

2. The bacteria in your intestines make you 'obese' more and more

The development of medicine tells us that the intestinal tract of humans consists of a lot of bacteria - also called microflora - that are beneficial for life.

Recently, however, scientists have more fully approached the ' utopian' possibilities that bacteria can do. As a result, these bacteria are seen as an important part equal to the liver or pancreas .

The intestinal bacteria contribute to regulating metabolic processes, supporting the immune system and fighting some diseases. They have a small number, up to 100 trillion cells in each person, accounting for 1-2 kg of total body weight.

However, not all bacteria are good. Some recent studies suggest that some types of intestinal bacteria have evolved and affected the vagus nerve - nerves that link the brain and intestines - that we always crave for Certain foods, which are specifically sugar and high-fat foods.

By secrete chemicals that affect the nervous system, stimulate appetite, increase the sense of satisfaction when being met, do these bacteria also make our diet more healthy, leading to the possibility of obesity or diabetes. However, according to scientists, the impact of bacteria will not be enough if you stand firm and follow a strict diet.

3. Find new parts in . knees

We always think that the knee is like a hinge, allowing people to stand on the ground. But in fact, the knee is a complicated machine , which causes the knee surgery to have a high failure rate and most of them leave sequelae.

In 2013, two Belgian knee surgeons questioned human knowledge about knee surgery. They discovered that the knee had another ligament in a very discreet position.

In fact, the mysterious ligament theory was introduced in 1879 by a French doctor named Paul Segon. He even asserted that he had found a mysterious ligament at the knee but failed to prove it, causing the theory to be dismissed soon.

After being demonstrated by Belgian doctors, this ligament called anterolateral ligament , helped make knee surgery more promising. However, this also causes scientists to ask: how many parts of the body have not been discovered?

4. Detecting stem cells in human teeth

Understanding stem cells is always a human desire, since only one cell can form any part of the body, including organs . Knowing stem cells means saving millions of people who are looking to the organ market.

Until now, stem cells were known only in embryos, but access had many social moral obstacles. Today, scientists discovered that they were able to access stem cells from cells inside adult teeth.

This finding almost rejects the long-held notion that stem cells grow only in one line, ie from stem cells to other cells, instead of vice versa. When observed, the nerve cells in the tooth somehow reverse the process of becoming stem cells.

After noticing the same phenomenon occurring in rats, the researchers performed a laser burning experiment, stimulating stem cells to quickly repair damaged teeth. This may help human science to new pages, with the potential to master stem cell technology from human teeth.

5. The brain has a switch

When hit hard on the head, people can lose consciousness. However, until recently, scientists have not been able to explain this phenomenon.

By 2014, a study found that there is actually a switch right inside our brain - that is, the basal ganglia (claustrum). This was discovered by accident when experts studied epilepsy. When the electric current acts on the basal ganglia, the patient falls into an unconscious state.

Once again, the patient regains consciousness, with a little memory remaining before being 'turned off' . This finding may open up a lot of research potential in medicine, especially about sleeping and sleeping problems.
