New Synthesis Process Enhances Sustainable Small Molecule Use

Researchers at Ruhr University Bochum, Germany, have discovered a new synthetic pathway with which they can produce a specific organic compound from the simple molecule carbon monoxide (CO), namely anionic ketenes. These were previously only known as reactive intermediates, and therefore couldn’t be used as defined reagents. The Bochum-based researchers produced anionic ketenes that were so stable that they could be isolated. Unlike previous methods, which can produce higher-value compounds from simple molecules, this approach doesn’t require any expensive or…

Chlamydiae: How Intracellular Bacteria Evolve and Adapt

Despite being intracellular symbionts, some chlamydiae could gain important genes through gene transfer from other bacteria. All chlamydiae today live inside the cells of hosts ranging from amoeba to animals. A team of scientists from the University of Vienna and the Wageningen University & Research found that the ancestor of chlamydiae likely already lived inside host cells, but that chlamydiae infecting amoeba evolved later in ways unexpected for intracellular bacteria. The study published in Nature Microbiology is an important step…
