Mid-infrared spectroscopy and supervised machine learning can determine age class of arboviral vector Culex pipiens at high age resolution

This study demonstrates that mid-infrared spectroscopy combined with supervised machine learning can accurately determine the age class of the arboviral vector *Culex pipiens* with high resolution, offering a promising tool for assessing pathogen transmission risks and evaluating vector control strategies.

Astroglial noradrenaline shapes cerebellar synaptic integration and motor adaptation

This study reveals that Bergmann glia serve as a local source of noradrenaline in the cerebellum, where calcium-dependent release via VMAT2 modulates synaptic integration in Purkinje neurons to drive adaptive motor behavior despite sparse traditional noradrenergic innervation.

Dietary Cocos nucifera milk mitigates D-galctose-induced aging and neurotoxicity in Drosophila melanogastervia modulation of oxidative stress and neurotransmitter dysfunction

This study demonstrates that dietary coconut milk mitigates D-galactose-induced aging and neurotoxicity in *Drosophila melanogaster* by modulating oxidative stress and neurotransmitter dysfunction, a mechanism supported by the high binding affinity of its bioactive component, oleic acid, to key enzymes like AChE and GST-2.

Constant recruitment annihilates limit cycles in environmentally transmissible disease models

This study demonstrates that assuming constant population recruitment in environmentally transmissible disease models can erroneously predict stable equilibrium states, whereas incorporating exponential or logistic recruitment reveals critical Hopf bifurcations and sustained oscillations, highlighting the necessity of accurate recruitment specifications to avoid misleading public health predictions.

The Warburg Effect Hallmark in Nasopharyngeal Carcinoma: Stage-Specific Up-Regulation of LDHA, GAPDH, CS, CYC, MRPL3, and TIMMDC1 Drives a Hybrid Glycolysis/OXPHOS Profile during Regional Progression

This study utilizes transcriptomic analysis to demonstrate that nasopharyngeal carcinoma progression is driven by a stage-specific hybrid metabolic phenotype, characterized by the coordinated up-regulation of six core genes (LDHA, GAPDH, CS, CYC, MRPL3, and TIMMDC1) that activate both glycolysis and oxidative phosphorylation during advanced regional disease.

Connectivity patterns in the DMN that are impacted by traumatic stress

Using a rat model of traumatic stress, this study reveals that while single prolonged stress generally decreases default mode network connectivity and disrupts its natural evolution, it paradoxically enhances specific connectivity patterns during extinction testing, particularly involving the anterior cingulate cortex and rostral retrosplenial cortex.
