Slime mold recorded on ISS
The single-celled creature grows and moves.
Mold is a powerful enemy for its hosts. It is quite difficult to get it out. And when you think that you have overcome it, then it appears in the most unexpected places at home. It is known that there is a slimy mold on the ISS, where it got thanks to a spacecraft, Chronicle.info reports with reference to Channel 24.
Physarum polycephalum slime mold looks like mold. So similar that for a long time he was considered her. But over time, slime molds won a kind of independence – they were no longer considered mold and were taken from the kingdom of mushrooms. They now have their own taxonomic group, Amoebozo, which belongs to the Unikonta mega-group of eukaryotes. So yes, there are more than just plants, animals and mushrooms.
How the slime mold got to the ISS
Physarum polycephalum is neither an animal, nor a plant, nor a fungus. Mucus consists of one cell and many nuclei. The creature also has about 720 articles.
The unique slime mold has no brains, but is capable of & # 171; acceptance & # 187; simple solutions and has primitive memory. The single-celled creature grows and moves.
Therefore, it is not surprising that this slime mold is ideal for the original school experiment that reached the height of the International Space Station.
Orbital School Experiment
< p>If you tear off a piece from Physarum polycephalum, then a new Physarum polycephalum will grow out of it. The scientists did just that. Several of these & # 171; pieces & # 187; sent to the ISS along with the Cygnus CRS NG-16 spacecraft, which docked with the station on August 12, 2021.
Now on the ISS one slime mold will be fed with cereals, and the other will starve. Scientists want to see what both Physarum will do in zero gravity. Where will they go? How will they grow? In what direction will they grow when there is no & # 171; bottom & # 187; and & # 171; top & # 187 ;?
At the same time on Earth, thousands of French schools will conduct an identical experiment. Students will receive & # 171; pieces & # 187; all the same Physarum polycephalum, the particles of which went into space.
Almost simultaneously 350,000 schoolchildren and astronauts of the International Space Station will begin observing organisms. Some will eat their fill, others will receive less food.
The experiment aims to popularize science among schoolchildren. Great scientific discoveries are not expected from him. But scientists hope that observations of different approaches to adaptation of slugs in space and on Earth will help answer some important questions of the formation of life.
