5 questions without answers about the human body

In recent years, the science industry has experienced great leaps and bounds. Our understanding of the human body has a better view than before. However, we do not fully understand all the issues surrounding the human body, even though we ourselves exist. Science recognizes that there are still many mysteries and new things to be discovered on the human body.

Why do people have fingerprints?

Although people are aware of the usefulness of fingerprints to help pinpoint someone, but scientists still cannot explain why at each finger of humans there are fingerprints. However, gradually, scientists also gradually discovered the abnormalities in their research.

They began their studies from genetic disorders called adermatoglyphia. This study was conducted with a number of families who were fingerprints free. After a while, the study showed that except for the unusual sign of sweating more than usual, these people seemed perfectly normal. The hope is that, by studying genetically modified families will eventually lift the mysterious veil of fingerprints.

The role of probiotics for the human body

If you've ever seen yogurt advertising you've probably heard of the phrase probiotics. People have always believed that probiotics play an important role, helping to improve their overall health. Meanwhile, yogurt companies seem to have found other benefits from probiotics. The truth is that this is a beneficial bacteria that lives in your intestines. Scientists have also begun to study the benefits of beneficial bacteria and conduct research on each type of bacteria. They believe that if science can answer all the questions about the benefits of each beneficial bacteria, it will mean the answer to how to treat the disease. This mysterious explanation may be a long journey, and is still a question mark.

Why have different blood groups

The first blood group was discovered about 20 million years ago. Until now, through a long period of research, scientists have not yet elucidated the activity of each blood group, and what is the fundamental difference between blood groups.

Scientists have predicted that blood type is related to disease, because the research process shows some interesting links. Some say that it is difficult to understand each blood type, and it is possible that blood group development is a way to fight disease. In short, this is still a hypothesis for scientists and all humans.

The brain can still function after being beheaded

This is like a bizarre story to scare young children, but in fact, scientists do not know for sure when the brain stops working after being beheaded. In many experiments that have been conducted, only Gabriel Beaurieux's research has yielded a clear phenomenon. After naming many times a man was beheaded, his eyes remained open and able to focus around looking for a short time until he completely closed his eyes. Doctors concluded that some human functions remained active for 30 seconds after being beheaded, and they could not explain it to the end.

Why do we have three ear bones?

A Stanford researcher named Sunil Puria showed that reptiles and birds have only two ear bones, while mammals have three ear bones. However, no scientist has found the cause of this.

According to Puria's research, people listen in many ways. First, we hear the sounds passing through the ears, and also hear the movements of the strings made through the bones in the skull. The concern in Puria's hypothesis is why people with third-ear bones are related to a strange disease called 'simicurcular canal dehiscence'. This disease can lead to a decrease in tissue in the ear canal, causing the listener to lose focus and not be aware. Puria said that the third ear bone works to minimize the risk of this disease. According to him, further research is needed to discover this secret.
