First complete DNA sequence of methanotroph reveals metabolic flexibility, suggests mechanisms for increasing its usefulness for biotechnology
The first complete genome sequence of a methane-breathing bacterium has revealed a surprising flexibility in its metabolism, suggesting an ability to live successfully in environments previously thought to be beyond its reach. The genome sequence of Methylococcus capsulatus – a species typical of methane-breathing bacteria commonly found in soils, landfills, sediments and peat bogs – includes a full and at times redundant toolkit of genes for using methane as an energy and carbon source. Such methane-consuming microbes are called methanotrophs.
The study, to be published in the October issue of PLoS Biology and posted online this week, found an unexpected flexibility in M. capsulatus metabolic pathways, hinting that the bacterium is capable of responding to changes in its environment by functioning through different chemical pathways for using methane. That finding, if confirmed by later experiments, may increase the bacteriums potential as a biotech workhorse.

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...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
