Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

Advanced Science, EarlyView.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

Gut Microbe‐Driven Resistance Mechanisms in Propylea Japonica: Insights from Horizontal Gene Transfer and Oxidative Phosphorylation

Advanced Science, EarlyView.
Acinetobacter regulates dinotefuran tolerance in Propylea japonica by mediating the expression of the horizontally transferred gene PjDUF1. Abstract Insect–microbial symbiont relationships are widespread in nature and often involve lateral gene transfer.

Polyphenol diet and exercise as neuroprotective factors in a Drosophila model of Alzheimer's disease

Animal Models and Experimental Medicine, EarlyView.
Moderate exercise and low‐dose ellagic acid supplementation improved motor performance, learning, and longevity in a transgenic Drosophila model of Alzheimer's disease. Both interventions showed hormetic effects—that is, beneficial at low levels, but detrimental at higher intensities or doses.

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.
