Genetic Impacts on the Structure and Mechanics of Cellulose Made by Bacteria
A genetic mutation in a protease of a cellulose‐overproducing evolved bacterium significantly affects the proteome, structure, and mechanical properties of bio‐fabricated cellulose pellicles. By overexpressing synthase proteins that build the cellulose‐forming biological machinery of the cell, the evolved bacterium generates dense, stiff, and strong ...

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance
This study employs three synapse‐specific endocannabinoids (eCB) probes to monitor dynamic eCB release, activate CB1Rs and knockdown 2‐AG biosynthesis enzymes in glutamatergic anterior basolateral amygdala ‐ ventral hippocampus (aBLA–vHPC) circuit. At aBLA–vHPC circuits, activation of CB1Rs reduce anxiety avoidance, and knockdown of eCB biosynthesis ...

A Subcircuit in the Suprachiasmatic Nucleus Generates Wakefulness
This study identifies a sub‐circuit within the circadian pacemaker suprachiasmatic nucleus (SCN) that promotes arousal. This sub‐circuit is labeled by the clock output molecule mWAKE, which suppresses its excitability in a time‐dependent manner. mWAKE‐expressing cells in the SCN (SCNmWAKE cells) project to the subparaventricular zone (SPZ) to mediate ...

Acidosis Forces Fatty Acid Uptake and Metabolism in Cancer Cells Regardless of Genotype
This study demonstrates that biological acidosis, commonly observed in tumors and ischemic conditions, actively promotes the protonation of fatty acids, thereby facilitating the uptake of their neutral forms. Consequently, the preference for lipid metabolism in acid‐exposed cells does not arise from genetic reprogramming that prioritizes lipids as the ...

Flame‐Retardant Ionogel Enabled by Lignin Molecular Networks for Fire Rescue
Wearable sensors for harsh, high‐temperature, fire‐prone environments face challenges in heat resistance and stability. This study introduces a flame‐retardant, waterproof glycol lignin ionogel (GLI) with a robust 3D network, exceptional tensile strength, strong adhesion, biocompatibility, eco‐safety, and dual temperature‐motion sensing, even after ...

A nanofabrication method enabling the direct growth of plasmonic nanostructures are presented on suspended tapered optical nanofibers via Blurred Electron Beam Induced Deposition (BEBID). By defocusing the beam to reduce mechanical stress, BEBID achieves sub‐20 nm precision and structural control, enabling directional scattering and light–matter ...
