Is it true that one fight is poor, two fights are rich?Chinese Academy of Sciences research results: know disease by hand or become possible

Remember that nursery rhyme you sang as a child?A bucket of poor, two bucket of rich, three bucket four bucket sell tofu.In their spare time, the elders will pull the children to their side and count how many buckets and dustpans there are on their fingers.A man with ten dikes in his hand could not help but be happy.Nursery rhymes, often circulated for hundreds of years, or even thousands of years, are the summary of life experience and wisdom of ancient people.Up to now, many people are still concerned about the number of “dustpans” and “buckets” on their hands.Can the number of “fights” in one’s hand really predict one’s future, as the nursery rhyme suggests?A research team from the Chinese Academy of Sciences and Fudan University has conducted an in-depth study of the “bucket” and “dustpan” found on fingerprints and discovered some secrets.How are “bucket” and “dustpan” formed?As we all know, there are no two identical leaves in the world, and everyone’s fingerprints are different.However, after long observation, ancient people found that although fingerprints of different people are different, they can also be classified according to the grain.According to the grain characteristics of fingerprints, fingerprints are divided into bucket type, bow type and dustpan shape.From the shape of the pattern, the pattern of the bucket fingerprint to a point as the center, uniform radiation around the pattern;The bow fingerprint is raised in the middle, shaped like a bow, spreading out;Dustpan type fingerprint lines, and dustpan on the bamboo stripe some similar.The reason why bow fingerprints are not mentioned in nursery rhymes is that Chinese fingerprints are rare, while American fingerprints are dominated by the bow pattern.The essence of “bucket” and “dustpan”, in fact, is a classification of the fingerprint, then “bucket” and “dustpan” is how to form?With the help of modern technology and equipment, scientists have found that, in fact, the fetus at the age of four months, fingerprint has been formed.As the fetus grows, fingerprints become apparent and become what we see.Modern genetics believe that when a fetus reaches about 10 weeks of age, a temporary bulge develops at the fingertips.This bump is similar to the pad on a cat’s paw and is the key to forming a fingerprint.As the baby grows, this bulge contracts and folds at the interface between the dermis and epidermis.As this compression intensifies, the wrinkles become more pronounced and dense, eventually forming a fingerprint.Simply put, the size and shape of the bump on the fingertip, to some extent, determines whether a fingerprint is a “bucket” or a “dustpan”.Figure out the “bucket” and “dustpan” formation process, that fingertips on the “bucket” and “dustpan”, for humans, and what role can play?Many people, after studying physics, assume that the lines on a fingertip increase friction, but this is not true.The “bucket” or “dustpan” on the fingertip, instead of increasing friction, will reduce the friction of fingers.When your fingers come into contact with other objects, they can hold them or put them down smoothly because of friction.The scientists found that as the strength of the fingers increased, friction did not increase.Using electron microscopy, the scientists determined that the furrows on the prints had about 30 percent less contact area than flat surfaces.Because of fingerprints, the area of contact between the fingertip and the object is reduced, so is friction.However, the study also found that the furrows in the fingerprint, depending on the strength, allow the skin of the fingertip to contract more smoothly, which can play a protective role.In addition, it is because there are “bucket” and “dustpan” shape lines on the fingertip, and these lines are often on different people, with unique, fingerprint is also used as an important basis for identification.In order to identify the fingerprint more accurately, the researchers subdivided the nodes on the fingerprint, including endpoint, bifurcation point, ring point, bifurcation point and so on.In fingerprint comparison, the similarity of two fingerprints can be basically determined only by identifying these key nodes.Through the previous analysis, it is not difficult to find that fingerprints in the fetal period, has been basically formed, the number of “bucket” and “dustpan” on the fingerprint, is it a sign of the future life?Scientific studies have shown that 95 percent of fingerprints are genetic, and the remaining 5 percent is environmental.However, a team of researchers from the Chinese Academy of Sciences and Fudan University have studied fingerprints in depth and found that although they do not predict a person’s poverty, they do give off some key signals.The findings, published in the journal Cell, suggest that the apparent features of fingerprints may be linked to some genetic diseases.For example, broken palm and bow-shaped ball marks of foot toe are very easy to appear in patients with Down syndrome.Scientists believe that many genetic diseases may have some common features on their fingerprints.More data analysis is needed on the relationship between fingerprints and genetic diseases, but it also shows that if enough samples are collected, it is possible to recognize diseases by looking at your hands.Although current medical equipment is more advanced and has more functions, more equipment means more tedious and more expensive tests.If certain characteristics of fingerprints could be determined, some diseases could be diagnosed, which would greatly improve the efficiency of consultations.Nowadays, it seems that the nursery rhyme of “one bucket of poverty, two bucket of wealth, three bucket and four bucket to sell tofu” is just a vision of the future of the ancients, and there is no practical basis for the saying that the number of “bucket” and “dustpan” to discuss the rich and poor.With the deepening of fingerprint research, the relationship between fingerprint and some genetic diseases will gradually become clear, which will also become a new way for human to understand their own physical conditions.It is worth mentioning that even if the fingerprint of the skin layer is smeared off, because the mastoid line of the dermis still exists, it can not change the number of “bucket” and “dustpan” on his fingers.With the development of IT technology, fingerprints can be used to unlock mobile phones and other electronic devices, and in certain scenarios, as payment density.As a part of the human body, fingerprints can not predict the wealth of the poor like the nursery rhyme, but because of the uniqueness and stability of fingerprints, with the continuous progress of technology, the future may have a greater use.
