Summary: In order to develop therapeutic strains, researchers have modified Escherichia coli Nissle (EcN) to express antibiotics, toxin-degrading enzymes, immunoregulators, and anti-cancer chemotherapies. To achieve high expression of recombinant genes, landing pads and genetic circuits have been developed to control gene expression in the EcN genome. These tools were successfully applied to EcN SYNB1618, a strain used for phenylketonuria treatment, resulting in higher activity compared to the original strain.

Summary: This study presents a methodology and dataset for examining compound wind and solar energy droughts, as well as the first standardized benchmark of energy droughts across the Continental United States (CONUS) for a 2020 infrastructure. The results show that compound wind and solar droughts have distinct spatial and temporal patterns across the CONUS, and the characteristics of energy droughts are regional. The study also finds that compound high load events occur more often during compound wind and solar droughts than expected.

Summary: This paper provides insights into the optimal configuration of CSP plants with different penetrations of wind power by proposing an unconstrained optimization model. The results suggest that large solar multiples and TES are preferred in order to maximize profit, especially when combined with high penetrations of wind and photovoltaic plants. Additionally, the study demonstrates the economy and feasibility of installing electric heaters (EH) in CSP plants, which show a linear correlation with the penetration of variable energy resources.
