A Generative AI‐Assisted Piezo‐MEMS Ultrasound Device for Plant Dehydration Monitoring

open access: yesAdvanced Science, EarlyView.
This study introduces a complementary metal–oxide–semiconductor (CMOS)‐compatible wearable piezoelectric micromachined ultrasound transducers (PMUTs) that sandwiches the leaf (PMUT–Leaf–PMUT, PLP) and employs generative artificial intelligence for real‐time analysis.

Additive Manufactured Magnetoelectric Wireless Retainer as the Periodontal Remodeler for Post‐Orthodontic Tissue Reconstruction and Relapse‐Inhibition

open access: yesAdvanced Science, EarlyView.
Orthodontic relapse persists as a 120‐year challenge, as traditional retainers fail to remodel tissue, causing lifelong dependence. This study demonstrates a flexible magnetoelectric retainer (FMOR) enabling wireless periodontal remodeling. FMOR cues shift periodontal ligament cell (PDLC) paracrine signaling, promoting M2 macrophages, osteogenic ...

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance

open access: yesAdvanced Science, EarlyView.
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

open access: yesAdvanced Science, EarlyView.
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 ...

Label‐Free Single‐Molecule Immunoassay

open access: yesAdvanced Science, EarlyView.
Label‐free single‐molecule immunoassay (LFSMiA) enables ultra‐sensitive and wide dynamic range protein detection in whole blood samples. LFSMiA features real‐time single‐molecule imaging by plasmonic scattering microscopy, background reduction by a 2‐step sandwich assay, minimizing matrix effect by dynamic tracking of single binding events, and ...

Healable Dielectric Elastomer Actuator With Premature Breakdown Warning Function for Information Transmission Encryption and Human‐Machine Interaction

open access: yesAdvanced Science, EarlyView.
An integral healable dielectric elastomer actuator (ISDEA) with a premature breakdown warning function is prepared based on the combination of electroluminescent dielectric elastomer and transparent compliant electrodes. Several ISDEAs are combined to construct soft anti‐counterfeiting labels and soft intelligent keyboards, expanding their potential ...
