Renaissance for magnetotactic bacteria in astrobiology
The ISME Journal, 2023 Capable of forming magnetofossils similar to some magnetite nanocrystals observed in the Martian meteorite ALH84001, magnetotactic bacteria (MTB) once occupied a special position in the field of astrobiology during the 1990s and 2000s.

The relevance of fungi in astrobiology research – Astromycology
Mycosphere, 2023 Since the very first steps of space exploration, fungi have been recorded as contaminants, hitchhikers, or as part of missions’ crews and payloads. Because fungi can cause human disease and are highly active decomposers, their presence in a space-linked ...

Theoretical constraints imposed by gradient detection and dispersal on microbial size in astrobiological environments [PDF]
Astrobiology, Vol. 21, No. 7, 813-830 (2021), 2021 The capacity to sense gradients efficiently and acquire information about the ambient environment confers many advantages like facilitating movement toward nutrient sources or away from toxic chemicals. The amplified dispersal evinced by organisms endowed with motility is possibly beneficial in related contexts.
