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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
