Summary: A new study demonstrates that long-term oral nicotine administration reprograms aging-related metabolism and slows motor decline in mice. By targeting the sphingolipid-energy axis, nicotine improved energy homeostasis, preserved gut microbial diversity, and supported neuromuscular resilience. Treated mice displayed a biologically younger phenotype based on integrated behavioral and metabolic analysis. The findings suggest nicotine’s molecular pathways may inspire the design …

Summary: A new study shows that some e-cigarette flavorings, like vanilla and cherry, can trigger reward-seeking behaviors in adolescent mice even without nicotine. Researchers found that these flavors alone could activate the brain’s dopamine system, raising concerns about their potential for fostering addiction-like behavior.
