Summary: Diazoolefins are highly reactive compounds that rapidly lose dinitrogen, and are observed to form in reactions of N-heterocyclic olefins with nitrous oxide. They display resonance stabilization, strong ylidic character, and good thermal stability, despite the presence of terminal N-2 groups. Diazoolefins can bind metal complexes without liberating dinitrogen and are strong electron donors, while also undergoing reactions involving the N-2 group.

Summary: This study characterized the structure of Chinese yam polysaccharide (CYP) and investigated its protective effect against oxidative damage. CYP showed antioxidative activity by improving cell viability, increasing superoxide dismutase activity, reducing reactive oxygen species generation, and decreasing malondialdehyde content. The protective effect of CYP was mediated through the modulation of the MAPK signaling pathway. These findings suggest that CYP has potential applications in the food and biopharmaceutical industries.

Summary: This study systematically identifies and characterizes genes in Z. mobilis that are conditionally essential for aerotolerant or anaerobic growth, as well as generally essential genes across both conditions. Furthermore, it reveals the importance of specific genes in powering essential biosynthetic reactions and provides insights into bacterial energy coupling. This research establishes Z. mobilis as a streamlined model for alphaproteobacterial genetics and has implications in the optimization of valuable bioproduct production.

Summary: Recent studies have found that bacterial strains isolated from surface environments and transferred under ambient pressure for decades still possess piezophilic characteristics under high hydrostatic pressure. This suggests that piezophiles may not be restricted to habitats with high pressure and have developed a common adaptation strategy to cope with various stresses. Transcriptomic analysis revealed differential gene expression related to antioxidant defense, intracellular compatible solute accumulation, and membrane lipid biosynthesis, which are crucial for cells to survive under high hydrostatic pressure.

Summary: Over the past decade, sampling and genomic efforts have revealed a vast quantity and diversity of life in Earth's extreme environments, presenting a challenge in understanding the molecular basis of life in such inhospitable conditions. This review discusses the physicochemical properties of extreme environments, recent progress in extreme environmental genomics, and the current understanding of biomolecular adaptation to extreme conditions, as well as the need for methodologies adapted to extreme conditions for studying extremophiles' biomolecular structure-function relationships. Possible future directions in extreme biophysics are briefly discussed.

Summary: Deep-sea hypersaline anoxic basins (DHABs) are uniquely stratified polyextreme environments found in enclosed seas, selecting for elusive microbes potentially living below Earth's recognized window of life. Specialized microbial communities have been found in the only known athalassohaline DHABs in the Eastern Mediterranean Sea. These environments have high magnesium chloride concentrations, reducing water activity and causing extreme chaotropic stress on biomolecules. Inconsistent measurements of chaotropic activity in literature highlight the need for new methodologies in studying these environments.

Summary: Hadal trenches are the deepest and least explored ecosystems on Earth. The genetic and physiological characteristics of the obligately piezophilic bacterium Moritella yayanosii DB21MT-5 isolated from the deepest oceanic sediment at the Challenger Deep, Mariana Trench have been revealed through comparative genomic analysis. The analysis identified depth-dependent distribution of energy metabolic pathways, compartmentalization of important metabolism and use of distinct defense systems, contributing to microbial adaptation to the extreme conditions of hadal trench.

Summary: Scientists are investigating the potential habitability of several permanently cold solar system bodies, such as Mars and icy moons. In this study, 14 strains of the bacterial genus Carnobacterium were subjected to cultivation under anaerobic conditions at 2°C and a range of pressures. Eleven of the strains showed measurable growth rates at all pressures tested, extending the physical boundaries of life in extreme extraterrestrial environments.
