Oceania is a unique continent due to its large content of truly unusual endemic species. This can be seen in the presence of animals as extravagant hooves, kookaburra or pink fish with their hands. Yeah, yeah, fish with your hands!
Compared with the bird's mammals, the birds whose songs the devil resembles human laughter or fish, whose fins allow them to walk at the bottom of the sea, Tasmanian devil It may seem very normal. But for that basketball The size of a small dog with a wide head, thick tail and black hair hides a large number of attractions that make it an animal worth living between platypus and fish with hands.
Species to be protected
It is said that Tasmanian devil so it was a cross the first European colonizers, which he compared with the devil for frightening gills which is broadcast every night during hunting. You can find it in the past throughout Australia, there is currently only one wild populae in the region island of Tasmania, located in the south of the country. This population has also fallen sharply in the last two decades curious infectious tumor, which affects yours face and passes through to the rest of the body until it causes death.
I was discovered in 1996 and since then it is estimated that he ended up with 80% of the population of the Tasmanian demon. In the end, it would be possible to turn off the series, if it were not, because it was strange that some of them have the capability to resist disease, a surviving tumor that finally stops treatment as if it were cold. This fact required the attention of a group of scientists from University of Washington, which he published in 2016 in Ljubljana Nature of communication a study describing the investigations carried out with these purses. Finally, this week, a new publication of the same team is analyzing genetic causes of this rebellion.
Especially rare are infectious tumors. Indeed, except facial tumor which destroys the Tasmanian demons, there is only evidence of two others: benign, which affects dogs, and another similar to leukemia that attacks mussels and mussels. However, these people do not suffer from this tumor, does not mean that their study can not be beneficial for us. In fact, according to researchers, some genes that appear to be involved in the Australian regression of the devil's tumor are common in humans, so that in the future his study could lead to development drugs that help fight cancer.
Milk to fight superbugs
The simple fact that they can provide essential keys for understanding the mechanisms involved in tumor regression already makes this animal a very interesting species. But the thing does not stop there, because your milk He also has a lot to teach scientists.
Some peptides present in milk have an interesting bactericidal effect
More specifically, it is very useful as a weapon in one of the most bitter battles that has had to fight man through its history: the fight against superbugs. According to the Spanish Agency for Medicinal Products and Health Products, 3000 people every year in Spain they die because of these bacteria that have developed their ability over time resist the attack of antibiotics. It is therefore crucial to discover alternative methods to combat them even before the disaster is even greater. Many researchers focus their work on searching Bactericidal substances in nature, which is often generated plants and animals typical for the most fortified cities in the world. And among them, of course, our friend could not be missed Tasmanian devil. This marsupia application was discovered in 2016 by a team of researchers from University of Sydney, with the analysis of some peptides present in milk.
Like in the other basketball players, offspring Tasmanian devil are born at a very early stage of development and theirs the first days of life, which in its case, within a bag which are found in the body of women. It does, too, with your own immune system without complete development, are constantly exposed to possible external infections that it causes bacteria or fungi. It is therefore very important that the milk that your mother has with her is a "mysterious ingredient" to help them fight. This power is in milk peptides, which are the masses of amino acids present in the milk of all mammals, with very uneven distribution. In fact, human milk contains only one, while it is from these animals You can have up to six.
After checking your antimicrobial potentialThese Australian scientists could synthesize the peptides in the laboratory and then test them on cultures of various bacteria. More specifically, they gave very good results Staphilococcus aureus multifunctional, superbug par excellence, as well as in Enterococcus resistant to vancomycin.
Of course, the Tasmanian devil is quite a lot FreakBut what would people do without them?
