A mysterious creature without a brain can help scientists study the mechanism of tissue regeneration.

According to the British BBC website.com, a strange yellow organism with the external characteristics of both a fungus and an animal was recently exhibited in a Paris zoological park. It is known that the unique type of mucous mold of Physarum polycephalum has almost 720 floors and is described by scientists as one of the unexplored secrets of nature. So, a creature is able to heal itself in two minutes if cut in half, endowed with the ability to think in the complete absence of the brain, and can also detect and digest food even in the complete absence of eyes, mouth and stomach.

Can mold think?

Although Physarum polycephalum maynot to cause at first glance any special interest due to their unicellular structure with a residual amount of DNA and proteins, biologists were able to prove that this unique type of mold is endowed with intelligence that allows Physarum polycephalum to make decisions and overcome artificially constructed obstacles. In 2001, a team of Japanese researchers divided the mold sample into several separate fragments that were evenly spaced around the perimeter of the maze. After several hours, the mold grew, connecting with its disparate fragments and, having reached the pieces of food left by the researchers, was able to crawl out of all the dead ends of the maze. Researchers noted that the mucus was not only able to successfully circumvent the obstacles of the maze, but was able to concentrate on the most efficient and fastest path in order to achieve the nutrients provided by scientists.

In other words, the study was able to show thatSome molds have a primitive intelligence that allows Physarum polycephalum to recall and analyze events. In addition, the experience helped to establish that the studied type of mold also has a unique ability to learn, despite the complete absence of the brain, which once again confirms the fact that the nature around us can be much more interesting than we could imagine to suggest.

The ability to regenerate mold cells to help study the mechanism of regeneration

The ability to regenerate most livingacquired the organisms of our planet about 500 million years ago, when the so-called Cambrian period dominated the Earth. Despite this, tissue regeneration occurs in completely different ways in creatures that have received any damage to the body, and, in addition to mold, we can observe its most striking manifestations in the organisms of worms and some reptiles. However, do not underestimate the person in whose body bone tissue that grows together after a fracture, hair, nails, and even some organs such as the liver and skin are capable of physiological regeneration.

Scientists believe that as livingcreatures, the ability to regenerate gradually loses its strength and significantly weakens. So, if a lizard is capable of autotomy (intentionally depriving itself of a tail) in case of danger, then a person, unfortunately, will not be able to restore a lost limb. But what if we should try to study the mechanism of regeneration of lower beings in order to understand the mechanisms of work of our own body? Well, according to Science magazine, US researchers believe that creatures with the ability to regenerate, including the unique type of mold Physarum polycephalum found, can really help humanity learn this very useful mechanism, once allowing us to make a real breakthrough in medicine .
