New microbe discovered aboard Chinese space station

"Scientists have identified a new microbe that developed on board China's Tiangong space station, according to a new study.

The strain, officially named niallia tiangongensis, is a new variant of a terrestrial bacteria and was found in a cabin inside the space station.
The discovery holds major implications for future space missions, astronaut health, and biosecurity.
Niallia tiangongensis demonstrated noteworthy resilience to space-specific stressors, including enhanced repair from radiation damage and the ability to survive oxidative stress—factors critical for maintaining long-term spaceflight safety.
Samples were stored at very low temperatures, returned to Earth, and subjected to genomic, metabolic, and phylogenetic analysis.
Researchers found that the new strain belongs to the genus niallia in the family cyto bacillaceae, but is genetically distinct from known relatives on Earth." ms
