Summary: This work presents the resistive switching characteristics of the TaOx-based conductive-bridge random-access memory (CBRAM) for neuromorphic engineering. The device can operate as both volatile and nonvolatile memory by controlling the Cu filament inside the TaOx film. It shows potential for short-term memory and long-term memory applications.

Summary: This study reveals that the regulation of c-di-GMP levels and colony morphology in Pseudomonas aeruginosa can follow different evolutionary paths. The delayed switching of c-di-GMP levels in response to fluctuating environmental conditions may provide a unique opportunity to close the gap between short-term phenotypic and long-term genetic adaptation.

Summary: In this paper, a synaptic transistor with a floating-gate (FG) node and an amorphous InGaZnO (IGZO) channel layer is proposed. The device emulates the neuroplasticity functions of both short-term memory (STM) and long-term memory (LTM) through the control of the amplitude and the number of input pulses. The STM occurs when the input amplitude is relatively small (< 9 V) by ion movement in the gate dielectrics, and the LTM occurs when the input amplitude is relatively large (> 10 V) by storing electrons in the FG. Increasing the number of input pulses allows for longer information storage. The FG IGZO synaptic transistor could be a promising device solution for brain-inspired computing systems.

Summary: This study introduces a Pt/Ta2O5/HfO2/TiN memristor with enhanced resistive switching behavior induced by inserting a HfO2 layer, demonstrating the influence of construction and destruction of oxygen vacancies in the HfO2 film on device performance. The low-power response of analog conductance changes with different dynamic synaptic characteristics was shown by adjusting pulse parameters, indicating valuable insight for optimizing synaptic performances in futuristic neuromorphic applications.

Summary: Wheat photosynthetic heat tolerance can be quantified using minimal chlorophyll fluorescence to measure the critical temperature. We investigated the intraspecies variation and plasticity of wheat T-crit under elevated temperature and found it to be unrelated to global patterns of interspecies heat tolerance. The observed genotypic variation and plasticity suggest that T-crit could be a useful trait for phenotyping wheat photosynthetic heat tolerance.

Summary: Research shows that mice lacking the Arc gene do not exhibit deficits in hippocampal long-term potentiation (LTP), indicating that Arc is not necessary for LTP in the hippocampus.

Summary: Memory consolidation is promoted by both sleep and wakefulness, but their effects on hippocampal and nonhippocampal representations differ. Sleep consolidation involves event-context binding, while wake consolidation tends to strengthen context-independent representations.

Summary: Acute social isolation in adult male rats results in social memory loss, accompanied by significant changes in the expression of specific mRNAs and proteins in the medial amygdala, a brain structure crucial for social memory. Upon regrouping, memory returns and most molecular changes are reversed, but some genes associated with neurodegenerative diseases remain modified for at least a day longer, suggesting that acute social isolation and rapid resocialization can induce significant changes to neuronal networks, some of which may be pathological.

Summary: Operations on high-dimensional fixed-width vectors can distribute information from multiple vectors over a single vector of the same width. Key-value pairs can be encoded into a single vector using multiplication and addition, and the superposition vector formed in this way can be queried for approximate values. An associative memory, which requires less memory and computing compared to a superposition vector, can be used to store and recall state-dependent behavior by brains.

Summary: Colibactin, a bacterial genotoxin produced by E. coli strains harboring the pks genomic island, induces cytopathic effects and may contribute to the pathogenesis of colitis. It can cause DNA breaks, cell cycle arrest, and apoptosis, leading to chronic impairment of tissue integrity. The expansion of E. coli in patients with inflammatory bowel diseases further supports this hypothesis.
