The cerebellum is activated by noxious stimuli and pathological pain but its role in noxious information processing remains unknown. Here, we show that in mice, cutaneous noxious electrical stimuli induced noradrenaline (NA) release from locus coeruleus (LC) terminals in the cerebellar cortex. Bergmann glia (BG) accumulated these LC-NA signals by increasing intracellular calcium in an integrative manner ('flares').

Age-dependent sensory impairment, memory loss, and cognitive decline are generally attributed to neuron loss, synaptic dysfunction, and decreased neuronal activities over time. Concurrently, increased neuronal activity is reported in humans and other organisms during aging. However, it is unclear whether neuronal hyperactivity is the cause of cognitive impairment or a compensatory mechanism of circuit dysfunction.

This study investigates the removal of total organic carbon (TOC) from paper mill wastewater using air dielectric barrier discharge (DBD) plasma, combined with various persulfate sources, namely potassium peroxymonosulfate (PMS), potassium peroxydisulfate (PDS), and sodium persulfate (SPS). Mechanistic insights into the activation of plasma-PDS and -PMS were obtained through quenching experiments and electron spin resonance (ESR) techniques. The addition of persulfate to air DBD plasma increased TOC removal kinetics by approximately 1.

Advancements in statistical techniques have expanded their use beyond simple population tracking to predict potential habitats based on the environmental conditions of sites detected eDNA. This study used species-specific molecular marker and targeted qPCR techniques to assess the distribution and habitat requirements of the endangered Gobiobotia naktongensis, a flagship fish species in Korean sandy river systems with increased public interest related to habitat restoration evaluations associated with dam construction.
