A newly discovered handwritten manuscript of Charles T. Jackson, MD, contains instructions for the preparation and administration of sulfuric ether, information on Jackson's preferred mixture of ether and chloroform, an account of his experiments with other potential anesthetic agents, and his comments on etherizing cattle and other animals. Jackson's nine-page manuscript is believed to have been written in the autumn of 1851, around the time that he submitted his memorial on the discovery of etherization to Baron von Humboldt, and made a separate submission to the US Congress.

Many bacterial toxins exert their cytotoxic effects by enzymatically inactivating one or more cytosolic targets in host cells. To reach their intracellular targets, these toxins possess functional domains or subdomains that interact with and exploit various host factors and biological processes. Despite great progress in identifying many of the key host factors involved in the uptake of toxins, significant knowledge gaps remain as to how partially characterized and newly discovered microbial toxins exploit host factors or processes to intoxicate target cells.

Globin X is a newly discovered member of the globin family, while its structure and function are not fully understood. In this study, we performed protein modelling studies using Alphafold3 and molecular dynamics simulations, which suggested that the protein adopts a typical globin fold, with the formation of a potential disulfide bond of Cys65 and Cys141. To elucidate the role of this unique disulfide in protein structure and stability, we constructed a double mutant of C65S/C141S by mutating the two cysteine residues to serine.

Microalgae offer a compelling platform for the production of commodity products, due to their superior photosynthetic efficiency, adaptability to nonarable lands and nonpotable water, and their capacity to produce a versatile array of bioproducts, including biofuels and biomaterials. However, the scalability of microalgae as a bioresource has been hindered by challenges such as costly biomass production related to vulnerability to pond crashes during large-scale cultivation. This study presents a pipeline for the genetic engineering and pilot-scale production of biodiesel and thermoplastic polyurethane precursors in the extremophile species .

Peptide cyclization is a defining feature of many bioactive molecules, particularly in the ribosomally synthesized and post-translationally modified peptide (RiPP) family of natural products. Although enzymes responsible for N- to C-terminal macrocyclization, lanthipeptide formation or heterocycle installation have been well documented, a diverse array of cyclases have been discovered that perform crosslinking of aromatic side chains. These enzymes form either biaryl linkages between two aromatic amino acids or a crosslink between one aliphatic amino acid and one aromatic amino acid.

The ferroelectric tunnel junction (FTJ) is a competitive candidate for post-Moore nonvolatile memories due to its low power consumption and nonvolatility, with its performance being strongly dependent on the conditions for contact between the ferroelectric material and the metal electrode. The development of two-dimensional materials in recent years has offered new opportunities such as functional metal layers, which is challenging for traditional FTJ systems. Here, we introduce the newly discovered ferroelectric metal WTe as the electrode to construct WTe/α-InSe/Au ferroelectric semiconductor junctions.
