An article in Journal of Applied Microbiology investigates how bacteria respond when they are subjected to environmental alterations, such as those of space stations, which feature lowered effects of gravity.
“Intra-specific differences in bacterial responses to modeled reduced gravity” by
Paul W. Baker and Laura G. Leff describes differences in bacterial responses to reduced gravity and how for some species, bacteria from the International Space Station (ISS), potentially are adapted to the unique environmental conditions of that system.
As bacteria are important residents in water systems, including those of space stations, examination of responses to conditions like microgravity may offer significant insight into the factors that influence bacterial distribution. In this study, water system bacterial isolates from the ISS were compared to other isolates from corresponding type strains of the same species. Reduced gravity was modeled using clinorotation. The findings suggest that conditions on the ISS might have favoured bacteria that were able to thrive under the unusual environmental conditions of this habitat. Responses to reduced gravity, coupled with impacts of other features (such as radiation resistance and the ability to persist under very low nutrient conditions), may contribute to the success of these water system bacteria.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
