In vivo fluorescence recording techniques have produced landmark discoveries in neuroscience, providing insight into how single cell and circuit-level computations mediate sensory processing and generate complex behaviors. While much attention has been given to recording from cortical brain regions, deep-brain fluorescence recording is more complex because it requires additional measures to gain optical access to harder to reach brain nuclei. Here we discuss detailed considerations and tradeoffs regarding deep-brain fluorescence recording techniques and provide a comprehensive guide for all major steps involved, from project planning to data analysis. The goal is to impart guidance for new and experienced investigators seeking to use in vivo deep fluorescence optical recordings in awake, behaving rodent models.

Microbial co-cultures provide significant advantages over commonly used axenic cultures in biotechnological processes, including increased productivity and access to novel natural products. However, differentiated quantification of the microorganisms in co-cultures remains challenging using conventional measurement techniques. To address this, a fluorescence-based approach was developed to enable the differentiated online monitoring of microbial growth in co-cultures.

Despite significant advancements in aerogels science, the fabrication of high-performance aerogels with their plastic processability remains unexplored owing to their inherent trade-off between skeletal rigidity and transformable processability. Herein, a universal solubility-pKa coupling-effect to engineer high-performance thermoplastic nylon aerogel family with excellent thermomechanical processing performance is proposed. By modulating solubility parameters and acid dissociation constants in nylon-solvent systems, it is precisely control crystallization to assemble interlaced 1D nanofiber skeletons, yielding nylon aerogels that integrate a high specific surface area (226 m g), exceptional compressive modulus (12.

An improved rotational characterization of the E3Σ1+(63S1) Rydberg state of the CdAr diatom produced in a supersonic beam and studied using laser induced fluorescence (LIF) excitation spectra is presented. As an example, the spectra of the E3Σ1+←A3Π0+(53P1) transition, originating from the excitation of a single 116Cd40Ar isotopologue, are recorded and analyzed. In the experiment, the optical-optical double resonance method is employed, utilizing the E3Σ1+(υ')←A3Π0+(53P1)(υ″=6)←X1Σ0+(υ=0) scheme.

The TRPA1 channel has recently emerged as a critical target for pain relief since its antagonists target the beginning of the pain transduction pathway and, thus, are devoid of side effects such as sedation, dizziness, somnolence, or cognitive impairment. Despite this clinical significance, currently, no TRPA1 inhibitors suitable for therapeutic usage exist to target these channels. Since ancient times, natural products have been known to be a rich source of new drugs, useful therapeutic agents, as well as pharmacological tools.

Hyperspectral data have been overshadowed by multispectral data for studying algal blooms for decades. However, newer hyperspectral missions, including the recent Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Ocean Color Instrument (OCI), are opening the doors to accessible hyperspectral data, at spatial and temporal resolutions comparable to ocean color and multispectral missions. Simulation studies can help to understand the potential of these hyperspectral sensors prior to launch and without extensive field data collection.
