TL;DR: If chemolithoautotrophic pathways were dominant in winter and were similar to those recently reported in global ‘dark ocean’ mesopelagic waters, this process may help account for the unexplained anomalies in surface inorganic nitrogen content.

TL;DR: Psychrobacter arcticus strain 273-4, which grows at temperatures as low as −10°C, is the first cold-adapted bacterium from a terrestrial environment whose genome was sequenced, and comparative genome analysis indicated there is reduced use of the acidic amino acids and proline and arginine, which is consistent with increased protein flexibility at low temperatures.

TL;DR: It is demonstrated that, although those most likely to develop long-term COVID-19 complications are those who initially have more severe illness, even those with mild or asymptomatic courses of infection are at increased risk of long- term complications.

TL;DR: It is shown that amino-acid sequences from the open ocean are reduced in N, but increased in average mass compared with coastal-ocean microorganisms, suggesting that N limitation is a stronger selective force in the ocean than biosynthetic costs and is an important evolutionary strategy in resource-limited ecosystems.

TL;DR: Insights from initial genomics studies on both cultivated organisms and genomes accessed through shotgun cloning of environmental samples suggest that there are many unique features of these organisms that facilitate survival in high-latitude, persistently cold environments.
