Magnetotactic bacteria align with Earth’s magnetic field using tiny internal structures called magnetosomes. This passive alignment is complemented by swimming with flagella and aerotaxis, facilitating navigation toward low-oxygen areas in aquatic environments. This article explores not only the basics but also the molecular mechanisms behind magnetically assisted navigation in bacteria.

To determine the drivers of phytoplankton biomass, we collected standardized morphometric, physical, and biological data in 230 lakes across the Mediterranean, Continental, and Boreal climatic zones of the European continent. Multilinear regression models tested on this snapshot of mostly eutrophic lakes (median total phosphorus [TP] = 0.06 and total nitrogen [TN] = 0.7 mg L −1 ), and its subsets (2 depth types and 3 climatic...

Summary The metabolism of polyhydroxybutyrate ( PHB ) and related polyhydroxyalkanoates ( PHAs ) has been investigated by many groups for about three decades, and good progress was obtained in understanding the mechanisms of biosynthesis and biodegradation of this class of storage molecules. However, the molecular events that happen at the onset of PHB synthesis and the details of the initiation of PHB / PHA granule formation,...
