Engineering New‐to‐Nature Biological Pathways for β,γ‐Alkanediol Synthesis

Advanced Science, EarlyView.
β,γ‐Alkanediols are value‐added chemicals to be used as functional solvents, biofuels, and cosmetic components. This work demonstrates a carboligation‐mediated approach for synthesis of linear chain β,γ‐alkanediols in Escherichia coli, namely, hexane‐2,3‐diol (2,3‐HDO) and pentane‐2,3‐diol (2,3‐PDO). The engineered E. coli cells produce 152.2 mm (17.98

Two fatal cases of plague after consumption of raw marmot organs

Emerging Microbes and Infections, 2020
Marmots are an important reservoir of Yersinia pestis and a source of human plague in Mongolia. We present two fatal cases of plague after consumption of raw marmot organs and discuss the distribution of natural foci of Y. pestis in Mongolia.

Epizootic Activity of Natural Plague Foci in the Territory of the Russian Federation in 2014 and Prognosis for 2015

Проблемы особо опасных инфекций, 2015
. Isolated were 128 plague agent strains: from rodents and lagomorphs - 24, 103 - from bloodsucking arthropods. One strain was obtained from a patient in the territory of Gorno-Altaisk high-mountain natural plague focus.

Wafer Scale III‐Nitride Deep‐Ultraviolet Vertical‐Cavity Surface‐Emitting Lasers Featuring Nanometer‐Class Control of Cavity Length

Advanced Science, EarlyView.
A DUV‐VCSEL strategy featuring the nanometer‐class control of the cavity length is proposed in the DUV optoelectronic framework based on GaN templates. After the sapphire removal, a self‐terminated etching technology is developed, whereby the cavity length can be accurately determined by epitaxy instead of the fabrication process. As such, a record low

Regulating Zinc Anode Interface with an Environmental Biomass‐Derived Additive for Long‐Lifespan Aqueous Batteries

Advanced Science, EarlyView.
A biomass‐derived additive synthesized from chitin, 3‐acetylamino‐5‐acetylfuran (3A5AF), resolves key stability issues such as uncontrolled dendrite growth, hydrogen evolution reaction, and corrosion of zinc anodes by reconstructing the solvation structure of the electrolyte and protecting the anode interface. ABSTRACT Aqueous zinc‐based batteries face

Systematic Engineering of Proteases in Saccharopolyspora Spinosa Reveals Synergistic Enhancement of Spinosad Biosynthesis via Substrate Flux Optimization

Advanced Science, EarlyView.
ARTP mutagenesis yielded Saccharopolyspora spinosa mutant D184 with improved extracellular nitrogen utilization. An integrated workflow of protease genetic manipulation, multi‐omics, and rational synergy design pinpointed a pepP‐clpP‐htpX synergistic triangular combination.
