Long‐Term Memory Updating Parallels Altered Awake and Sleep Hippocampal Replays

open access: yesAdvanced Science, EarlyView.
This study introduces a behavioral paradigm for memory updating and reveals underlying hippocampal mechanisms. Replays of place cells predict future behavioral choices during behavior and show a bias toward high‐reward locations during non‐rapid eye movement (NREM) sleep, specifically within the memory updating process.

Calhm6 Governs Macrophage Polarization Through Chp1‐Camk4‐Creb1 Axis and Ectosomal Delivery in Inflammatory Responses

open access: yesAdvanced Science, EarlyView.
Calhm6 drives M2 macrophage polarization via the Chp1‐Camk4‐Creb1 axis, suppressing inflammation through calcium‐dependent ectosomal delivery. Calhm6 deficiency enhances M1 responses, boosting bactericidal activity but exacerbating tissue damage. LPS/IFNγ upregulate Calhm6 via Irf1, while IL‐4/Stat6 inhibits it, balancing immune outcomes.

AGS3 and Gαi3 Are Concomitantly Upregulated as Part of the Spindle Orientation Complex during Differentiation of Human Neural Progenitor Cells

open access: yesMolecules, 2020
Adult neurogenesis is modulated by many Gi-coupled receptors but the precise mechanism remains elusive. A key step for maintaining the population of neural stem cells in the adult is asymmetric cell division (ACD), a process which entails the formation ...

CCDC41 Drives Oocyte Meiotic Progression by Promoting Rab11a/Rab7‐Positive Vesicle Fusion with Target Membranes

open access: yesAdvanced Science, EarlyView.
CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,

The Geometry of Layer 2/3 Cortical Sound Processing in Slow Wave Sleep

open access: yesAdvanced Science, EarlyView.
Sleep is associated with a sensory disconnection whose mechanisms remain elusive. Large neuronal population recordings in the auditory cortex revealed that, in NREM sleep, the neural code for sounds is highly similar to wakefulness, but coordinated modulations of neuron responsiveness intermittently disconnect the local cortical networks from sensory ...

Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts

open access: yesAdvanced Science, EarlyView.
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

Comment on “Sperm Injection at the Para‐Polar Body Site in Piezo‐Intracytoplasmic Sperm Injection Improves Subsequent Early Development of Bovine Embryos”

open access: yesReproductive Medicine and Biology
Piezo‐intracytoplasmic sperm injection (piezo‐ICSI) is increasingly used to reduce mechanical damage during sperm injection. In the recent study by Ashibe et al., placing the first polar body (PB) at the 2 or 4 o'clock position (“para‐PB piezo”) improved

Under‐Urine‐Adhered Supramolecular Hydrogel with Linearly Sustained Quercetin Release Facilitates Hemorrhagic Cystitis Healing via Inflammation Regulation

open access: yesAdvanced Science, EarlyView.
A supramolecular gelatin‐based hydrogel adhesive was engineered for hemorrhagic cystitis management. It provides robust wet‐tissue adhesion, rapid hemostasis, sustained quercetin release, effectively restoring the bladder barrier via anti‐inflammatory and antioxidant actions.
