Summary: Metal anodes are highly desirable for next-generation batteries due to their high capacity and low potential. However, challenges such as dendrite growth and volume change hinder their practical applications. This study demonstrates the use of organic and inorganic hybrid interfaces to achieve stable electrochemical performance for Li- and Na-metal anodes. The optimized thicknesses of the nanoalloy interfaces differ for Li- and Na-metal anodes, and the mechanical stability of the interfaces influences the electrochemical performance. This research establishes a fundamental understanding and connection between mechanical properties and electrochemical performance for alkali-metal anodes.

Summary: Archaeal glycerol dibiphytanyl glycerol tetraethers (GDGT) are unusual membrane lipids found in Archaea, including extremophiles. Interest in studying their biophysical properties and biosynthesis is high, but limited access to pure samples has hindered progress in this area. This study reports a concise synthesis method for archaeal tetraether lipid parallel GDGT-0 and derivatives with different polar groups for self-assembly.

Summary: This study presents a novel chemoenzymatic approach to reconstitute lipid membranes, optimizing phospholipid formation in a cell-free system. The one-pot synthesis of membrane-bound vesicles was achieved, as well as the synthesis of noncanonical sphingolipids. The coupling of gene expression with membrane lipid synthesis could lead to the generation of proteoliposomes, advancing the bottom-up generation of synthetic cells.

Summary: The study demonstrates rapid de novo formation of biomimetic liposomes in water using dual oxime bond formation between two alkyl chains and a phosphocholine head group. Membranes can be generated from non-amphiphilic, water-soluble precursors at physiological conditions using micromolar concentrations of precursors. Functional membrane proteins can be reconstituted into synthetic oxime liposomes from bacterial extracts in the absence of detergent-like molecules.

Summary: Archaea, one of the three fundamental domains of life, possess unique lipids in their cell membranes which provide stability and enable the formation of various membrane structures. The complex nature of archaeal lipids makes their chemical synthesis challenging, but efforts are being made to develop simplified synthetic routes. Understanding archaeal lipids can shed light on the survival mechanisms in extreme environments and the origins of cellular life.

Summary: In cells, membrane lipids are formed by enzymatic reactions. However, it is unclear if similar lipids could have spontaneously formed without enzymes at the origin of life. This study reports the unexpected chemoselective O-acylation of 1,2-amino alcohol amphiphiles in water directed by Cu-(II) and other transition metal ions. The results suggest that simple mechanisms for aqueous esterification may have been prevalent on earth before the evolution of enzymes.

Summary: This study systematically characterizes the interaction of DNA with lipid sponge droplets, demonstrating a strong size dependence for DNA functionalization. Shorter DNA molecules efficiently partition into the lipid sponge phase and can direct DNA-templated reactions to droplets. This system opens new opportunities for DNA-encoded functions in lipid sponge droplets.
