New forms of 'dark life' discovered in strange environments
The search for dark matter has been a search for physicists for decades. While some evidence suggests that the universe could be composed of up to 85% of this invisible and undetectable form of matter, scientists still have to identify it conclusively in nature; most of the evidence is obtained from the unexplained gravitational effects that something It is exercising on the subject that we can see. Is there really dark matter or is it the theory of the four current humors?
Time will tell. Meanwhile, scientists in a different discipline are discovering evidence that other types of dark matter may be around us: living matter. According to recent discoveries in microbiology, there could be a whole branch of the tree of life composed of unknown forms of "dark life." Only a few hundred years have passed since Hooke and Van Leeuwenhoek discovered microorganisms, just imagine what we will know a few hundred more. the Really weird things.
Microbes under the microscope
Mark Miller, a biochemist at the University of California at San Diego, was recently award-winning About $ 3 from the National Science Foundation and National Institutes of Health to study these mysterious dark ways of life. According to Miller, advances in computing power have produced evidence of unknown life forms that resist being grown in Petri dishes the way other microbes can. Part of the reason why these life forms have avoided discovery is the fact that they live in exotic or almost unreachable environments, such as in deep-water vents or in the mouths of dolphins. Yuk
If you ever drop your sandwich in the mouth of a dolphin, simply consider that it's gone forever. Trust me.
Soon, Miller He saysIt is possible that we can prove conclusively the existence of these organisms through the massive collection of data made by supercomputers:
The dark life is those organisms that are not visible to the human eye and can not be cultivated successfully. It is a kind of hallucinatory. There is a set of metabolic pathways that, as a classical training biochemist, I believe are essential for life that seem to be lacking in these new organisms. And until we had these sophisticated DNA techniques available, we could not detect it either.
"This is an interesting time," adds Miller, "because DNA sequencing is cheap: you can get all the data you want, but you get so much data that you get choked on that." drowning in the croissants on live television.
Could we be about to discover completely new ecosystems of unknown organisms? Since the search for extraterrestrial life has led to focusing on microbesTherefore, this type of research will be essential to provide space agencies with the tools they need to explore new strange worlds, seek new lives and new civilizations, and boldly go where no one has gone before. Could the first contact occur in our life? Even if it's with a microbe, I'll take it as a victory.
