Monolithically‐Integrated van der Waals Synaptic Memory via Bulk Nano‐Crystallization

Advanced Science, EarlyView.
Monolithically‐integrated van der Waals synaptic memory is presented via bulk nano‐crystallization, which overcomes the conventional limitations of 3D device integration technologies. Furthermore, bipolar resistive switching (LRS/HRS) dynamics is spatially resolved with conductive atomic force microscopy, scanning‐transmission electron microscopy, and ...

Enhanced Protein Synthesis and Hippocampus‐Dependent Memory via Inhibition of YTHDF2‐Mediated m6A mRNA Degradation

Advanced Science, EarlyView.
YTHDF2‐mediated m6A mRNA decay critically regulates learning and memory. Its forebrain‐specific knockout in mice impedes degradation of m6A‐modified mRNAs, enhancing hippocampal synaptic transmission, protein synthesis, and memory. Conversely, hippocampal YTHDF2 reintroduction or SEMA4B reduction reverses this enhancement, while its overexpression ...
