Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

Advanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

Synchronized Imaging of Hydrogen Peroxide and Hydroxyl Radical in Pyroptosis and Epilepsy

Advanced Science, EarlyView.
A dual‐responsive fluorescent probe, HH, enables synchronized visualization of H2O2 and •OH through spectrally resolved green and red channels. By tracking redox dynamics in pyroptosis and epilepsy models, HH reveals ROS elevation during seizure‐like pathology and supports evaluation of antioxidant and antiepileptic therapeutic interventions.

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

Advanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

The Plant‐to‐Plant Circular Strategy: Coupling Photodegradation and Phytoremediation With Plant‐Based Nanomaterials for Plastic Degradation

Advanced Science, EarlyView.
Plant‐based nanomaterials derived from alfalfa serve as dual‐function catalysts, coupling photodegradation and phytoremediation to degrade polyethylene under UV‐A light and in soil. The nanomaterials work synergistically with alfalfa and soil microbes, achieving efficient plastic breakdown without trophic transfer.

Adaptation of Echinococcus Multilocularis to Oxidative Stress Depends on EmPDK‐Mediated Metabolic Reprogramming

Advanced Science, EarlyView.
Metabolic adaption presents a vital survival strategy for E. multilocularis. This study identifies EmPDK as a central metabolic regulator governing glucose metabolic reprogramming. Oxidative stress activates EmHIF1α to induce EmPDK expression. Mechanistic characterization reveals this ROS/EmHIF1α/EmPDK axis drives glycolytic reprogramming to sustain ...
