An Amide-Based Gel Polymer Electrolyte for Li-O2 Batteries: Advancing Towards Practical Li-Air Batteries
This study introduces an amide-based gel polymer electrolyte (GPE) for Li-O2 batteries, optimizing monomer and plasticizer ratios to enhance electrochemical stability and cyclic performance. The GPE addresses sluggish kinetics and anode corrosion, enabling operation under atmospheric conditions, and demonstrating significant durability for practical Li-air batteries.

• Year-to-year variability in LDL and total cholesterol was tied to risk for dementia and cognitive decline in older adults. • Variability in triglycerides and HDL was not linked to risk for cognitive decline. CHICAGO — High year-to-year cholesterol variability was linked to increased risk for cognitive decline and dementia among older adults, a speaker reported.

AbstractThe complex biological mechanisms underlying human brain aging remain incompletely understood. This study investigated the genetic architecture of three brain age gaps (BAG) derived from gray matter volume (GM-BAG), white matter microstructure (WM-BAG), and functional connectivity (FC-BAG). We identified sixteen genomic loci that reached genome-wide significance (P-value < 5×10−8).

2.2. Biological Fermentation Methods 2.2.1. L-Cysteine Biosynthesis in E. coliIt is well known that in most microorganisms and plants, L-serine is the precursor substance for the synthesis of L-cysteine. The biosynthetic pathway of L-cysteine has been widely reported after many years of research [4,27,28]. In gut bacteria, L-serine is synthesized via a three-step pathway from the glycolytic intermediate 3-phosphoglycerate, and L-cysteine is synthesized via a two-step pathway from L-serine [28].

Editor’s summaryYeast cells have a transcriptional toggle switch that leads them to die by one of two fates: One causes death by nucleolar decline, the other by mitochondrial decay. By rewiring this transcriptional switch into a negative-feedback loop, Zhou et al. were able to cause yeast cells to oscillate between the two states and increase their life span by 82% (see the Perspective by Salis).
