Summary: By studying spontaneous bursts in cultured rat cortical neuron networks, it was found that the learning phase promotes the occurrence of spontaneous burst activity and leads to the emergence of new burst propagation patterns. During the learning phase, a small number of specific populations carried the majority of stimulus information and contributed to learning.

Summary: This study presented an MEA with cathode ordered catalyst layer to improve mass transfer characteristics and durability. TiO2 nanowire arrays were prepared on the porous surface of carbon paper and the catalyst was uniformly applied by ultrasonic spraying. The results showed that the peak power of the cathode ordered MEA can reach 539.5 mW/cm2 at a platinum loading of 0.21 mg/cm2. Comparing with other processes, the combination of ultrasonic spraying and cathode ordered structures is a promising solution for developing efficient and stable MEA.

Summary: Brain-state alternation plays a crucial role in long-term memory formation. Using an in vitro neocortical-hippocampal coculture model, researchers found different rhythmic bursting coupling patterns between the neocortex and hippocampus in different brain states, which influenced network synchronicity and information processing states.

Summary: We investigate a class of fractional time-partial differential equations to describe the dynamics of fast action potential process in contractile myocytes. The study explores the system in both one and two dimensional cases and derives both homogeneous and nonhomogeneous solutions. Numerical simulations of proposed fractional solutions reveal that the diffusion-wave equation with fractional order can effectively model the dynamics of membrane potential, especially with lower fractional order values serving as an extra asset to modulate electricity conduction.

Summary: This study presents a light-addressable paper-based photoelectrochemical (PEC) analytical device for on-site high-throughput biosensing. The device consists of a solar cell-type single-channel PEC system with separated detection zones, and can be produced in large quantities using a simple method. By taking advantage of the sensitive photocurrent response, an AChE-based PEC biosensing system for the on-site screening of ultratrace pesticides was established.

Summary: Electrode-based impedance and electrochemical measurements can provide non-invasive, label-free cell-biology information, overcoming limitations of optical imaging. However, existing electrode-based techniques have noisy results due to the limited number of electrodes per well. New field-based impedance mapping and electrochemical mapping/patterning techniques using CMOS-MEA expand the possibilities of cell-biology applications, with single-cell spatial resolution.

Summary: Metal sulfides as supercapacitor electrode materials have large theoretical capacity and rich operability, but their unsatisfactory cycle stability and rate performance are challenging problems. Therefore, the effective strategy to solve these problems is the preparation of metal sulfide-based electrode materials with a stable structure, long cycle life, and high-rate performance. In this study, metal sulfides were first crystallized into crosslinked nanosheet and nanotube structures, providing abundant active sites for redox reactions. Further modification of the prepared material by spraying graphene resulted in a more complete hollow structure, enlarged electrochemical reaction sites, and reduced electrolyte transport distance, thereby improving the charge transfer kinetics. The electrode material underwent a self-activation process during the charge-discharge cycle test, transforming it from one equilibrium state to a new equilibrium state. The 2-CSNS@RGO electrode showed a capacitance of 1650.13 C g(-1) at 1 A g(-1) with remarkable cycling of 3000 cycles at 10 A g(-1), retaining 186.1% capacity of the initial value. An asymmetric supercapacitor (2-CSNS@RGO//AC) was prepared using 2-CSNS@RGO as the positive electrode and activated carbon (AC) as the negative electrode, exhibiting an energy density of 88 W h kg(-1) at a power density of 0.8 kW kg(-1) and a capacity retention rate of 131.6% after 30,000 cycles at 10 A g(-1).

Summary: The use of ordered catalyst layers, such as the ordered Nafion array, has shown great potential in reducing catalyst loading and improving fuel cell performance. By optimizing the Nafion solvent, thermal annealing temperature, and stripping mode, a 40 nm diameter ordered Nafion array (D40) was successfully prepared, providing abundant proton transfer channels and a large area for catalyst loading. The fuel cells with D40 demonstrated significantly higher peak power densities and reduced catalyst loading compared to those without the array.

Summary: The study found that poplar was more sensitive to half stress and showed lower gas exchange rates and pigment values, while willow demonstrated increased root growth in response to heterogeneous zinc exposure without negative impact on shoot physiology. These significant differences between the two species in response to patchy distribution of toxic zinc concentration may impact the efficiency of phytoremediation efforts and suggests additional criteria to consider in the pre-selection process.

Summary: Using Arabidopsis thaliana cultured cells, this study analyzed early cellular responses to sorbitol-induced hyperosmotic stress, revealing biphasic and dual responses in the cells. These responses included survival adaptation through signaling and osmotic adjustment, as well as programmed cell death in part of the cell population, raising questions about the induction of different behaviors in response to the same hyperosmotic condition.

Summary: This study revealed that the responses in roots, rather than in shoots, were crucial for greater salt tolerance in quinoa accessions with low epidermal bladder cell (EBC) density. The tolerant accession showed improved root plasma membrane integrity and ion retention in response to salt, along with faster and root-specific oxidative stress responses within 30 minutes of salt application. This demonstrated that differential root signaling events are essential for halophytic quinoa adaptation to salinity, independent of salt sequestration in EBCs.

Summary: Microalgae in the wild often form consortia with other species, promoting their own health and resource foraging opportunities. However, the application of microalgae cultivation and deployment in commercial photobioreactors (PBR) has mostly focused on single species, neglecting the exploration of multi-species consortia. This article argues for further investigation into algal communication with conspecifics and interspecifics to understand the potential of incorporating algal-microbial consortia in PBR configurations for improved efficiency.
