Article Synopsis
  • Lithium metal electrodes in rechargeable batteries face issues like high reactivity and significant volume changes, leading to degradation in performance over time.
  • A new approach introduces a super SEI-forming anion (SSA) that enhances the stability of the interface on lithium electrodes, improving how well the surface is covered and how uniformly it distributes.
  • The use of SSA significantly boosts the lifespan and performance of lithium metal batteries, offering over five times the cycle life compared to traditional anions, paving the way for better battery technologies.

A growing body of evidence suggests that children with dyslexia in alphabetic languages exhibit visual-spatial attention deficits that can obstruct reading acquisition by impairing their phonological decoding skills. However, it remains an open question whether these visual-spatial attention deficits are present in children with dyslexia in non-alphabetic languages. Chinese, with its logographic writing system, offers a unique opportunity to explore this question.

Article Synopsis
  • The text discusses the challenge of minimizing active lithium loss in rechargeable lithium batteries, especially for grid-storage use, where high energy density and long life are crucial.
  • It introduces a new solution called a designer lithium reservoir (DLR) using lithium orthosilicate and sulfur, which helps reduce lithium loss and improve battery efficiency by supporting solid electrolyte interphase (SEI) formation.
  • A prototype battery with a small amount of DLR showed impressive cycling stability and capacity retention (about 95% after 3000 cycles), paving the way for better lithium batteries in grid-storage and other applications.

How rigidly does innate architecture constrain function of developing cortex? What is the contribution of early experience? We review insights into these questions from visual cortex function in people born blind. In blindness, occipital cortices are active during auditory and tactile tasks. What 'cross-modal' plasticity tells us about cortical flexibility is debated.

Silicon (Si)-based anodes are currently considered a feasible solution to improve the energy density of lithium-ion batteries owing to their sufficient specific capacity and natural abundance. However, Si-based anodes exhibit low electric conductivities and large volume changes during cycling, which could easily trigger continuous breakdown/reparation of the as-formed solid-electrolyte-interphase (SEI) layer, seriously hampering their practical application in current battery technology. To control the chemoelectrochemical instability of the conventional SEI layer, we herein propose the introduction of elemental sulfur into nonaqueous electrolytes, aiming to build a sulfur-mediated gradient interphase (SMGI) layer on Si-based anodes.

Article Synopsis
  • Research indicates that brain functions adapt based on sensory experiences, exploring differences between blind and sighted individuals.
  • The study compares functional connectivity in blind adults, sighted adults, and a large group of sighted infants, revealing that infant visual cortices more closely resemble those of blind adults.
  • The findings suggest that visual experiences are necessary for developing certain brain connections, with variations in connectivity patterns observed between primary visual cortices and higher cognitive areas in both sighted and blind individuals.

Article Synopsis
  • Inorganic solid-state electrolytes (ISSEs) are crucial for all-solid-state lithium-metal batteries (ASSLMBs), showing high ionic conductivity but often struggle with poor compatibility with lithium-metal anodes.
  • The proposed LiInCl/LiOHCl bilayer halide ISSEs offer improved interfacial compatibility and thermal stability, performing well at temperatures up to 160 °C.
  • These bilayer ISSEs enable the development of AISSLMBs with excellent cycling life and rate performance, demonstrating over 3000 hours of stability at 80 °C through a simple cold-press method.

Rechargeable lithium-based batteries built with high-energy anode materials (e.g., silicon-based and silicon-derivative materials) are considered a feasible solution to satisfy the stringent requirements imposed by emerging markets, including electric vehicles and grid storage, due to their higher energy density compared to contemporary lithium-ion batteries.

Article Synopsis
  • The study investigates how reading processes differ between sighted individuals using visual print and congenitally blind individuals using tactile Braille, focusing on neural activity in the brain.
  • Results showed that while both groups activated similar brain areas (specifically the ventral occipitotemporal cortex), only sighted readers exhibited a gradient of activation based on the complexity of the written words they were processing.
  • Findings indicated that blind readers relied more on different brain regions (posterior parietal cortices) compared to sighted readers and that the processing of Braille is influenced by their spoken language and reading hand preferences.

Article Synopsis
  • * Two specific regions in the cerebellum, right lobule VI and right lobule VIIIA, showed increased activation when participants viewed Chinese characters and English words compared to non-reading tasks.
  • * However, the researchers found no distinct cerebellar responses to print differences between Chinese and English; instead, a stronger functional connectivity was noted in the context of English reading.

  • Non-coding RNAs (ncRNAs) like circular RNAs (circRNAs) and microRNAs (miRNAs) are crucial for gene regulation, particularly in the immune response of turbot fish infected by pathogens.
  • A study used high-throughput sequencing to analyze differentially expressed circRNAs, miRNAs, and mRNAs in the spleen of infected turbot, identifying significant changes linked to immune pathways.
  • The research constructed a circRNA-miRNA-mRNA regulatory network with 96 interactions, suggesting that ncRNAs play a role in regulating immune-related genes during pathogen infections in turbot.

Galectins, a family of evolutionary conserved β-galactoside-binding proteins, have been characterized in a wide range of species. Many reports have indicated vital roles of galectins in innate immunity, especially in the mucosal tissues against infection. However, the systematic identification of galectin gene family is still lacking in teleost.

Cathepsins, a superfamily of hydrolytic enzymes produced and enclosed within lysosomes, play multiple roles at physiological and pathological states. Cathepsin S is a lysosomal cysteine endopeptidase of the papain family, and exerts critical roles in the regulation of MHC class II immune responses. In the present study, we captured two Cathepsin S genes in turbot (SmCTSS1 and SmCTSS2.

The engagement of the cerebellum VI in reading was reported in both typically developing and dyslexic readers. However, it is still not clear how the cerebellum VI contributes to reading. Here we have examined the correlation of intrinsic cerebro-cerebellar functional connectivity with two critical reading-related skills-phonological awareness (PA) and rapid automatized naming (RAN)-with fMRI technology.

The immune system protects organism from external pathogens, this progress starts with the pathogen recognition by pattern recognition receptors (PRRs). As a group of PRRs, the class B scavenger receptors showed important roles in phagocytosis. Among three class B scavenger receptors, lysosomal integral membrane protein type 2 (LIMP-2) was reported to present in the limiting membranes of lysosomes and late endosomes, but its immune roles in teleost species are still limited in handful species.

Mucosal immune system is one of the most vital components in the innate immunity and constitutes the first line of host defense against bacterial infections, especially for the teleost, which live in the pathogen-rich aquatic environment. Cathepsins, a superfamily of hydrolytic enzymes produced and enclosed within lysosomes, play multiple roles at physiological and pathological states. In this regard, we sought here to identify Cathepsin A in turbot (SmCTSA), characterize its mucosal expression patterns following Vibrio anguillarum and Streptococcus iniae infections in mucosal tissues, and explore its binding ability with three microbial ligands for the first time.
