Dozens of Baby Squids Hawaii It was launched into space this month.
NASA sent 128 Hawaiian Bobtail squids to the International Space Station as part of its SpaceX replenishment mission on June 3. Scientists have studied how they interact with natural bacteria under low-gravity conditions.
“We have found that the symbiosis between humans and microorganisms is being confused by microgravity,” he said. Said Margaret McFaul Nai, a professor at the University of Hawaii. Now, with her college in Florida, Professor Jamie Foster wants to observe a similar phenomenon in cuttlefish..
The experiment is part of the NASAUnderstanding Microgravity in Animal-Microbe Interactions or Umami program.
Foster worked with NASA to send squids into space. Similar experiment in 2011.
Squids that grow to be around 3 inches long have bacteria in their bodies that regulate bioluminescence. In the wild, they camouflage themselves in the moon and starlight to create a glow to hide from sea predators.
According to McFall-Ngai, when an octopus hatches in the ocean, there are 4 million bacterial cells per square inch around the octopus, but among the millions of other microorganisms, the quality of bioluminescence. We are aware of the variety of specific symbiotic organisms that regulate.
An octopus will be on display at a laboratory in Honolulu on June 11, 2021. Dozens of baby squids from Hawaii are in space for research.

The human immune system also identifies beneficial bacteria from dangerous bacteria, but the process is confusing to astronauts due to stressors such as radiation and microgravity. The immune system will not function normally again until the astronaut returns to Earth. According to NASA research.
“When astronauts spend more time in space, their immune system becomes so-called dysregulated. It doesn’t work either. Your immune system doesn’t recognize bacteria easily. Sometimes they get sick. “I will,” said Foster.
Researchers are first exposing bacteria to octopuses that have hatched in a controlled laboratory environment. After 12 hours of integration of symbiotic organisms, the organism will be frozen and tested at the molecular level when it returns to Earth in July.
Understanding what happens to squid and its bacteria can improve astronauts’ health, Foster says, and send them on missions longer than NASA’s stay on the International Space Station for a year. It can be.

“There are aspects of the immune system that don’t function properly during long space flights. If people want to spend time on the Moon or Mars to get there safely, we need to solve our health problems. “
