Skeletal muscle communicates with other tissues by using extracellular vesicles  — particles that play a role in cell-to-cell communication, including telling fat cells to go into "fat-burning mode."

The cytokine interleukin-25 supports the production of "beige fat", which has high amounts of energy-burning mitochondria. These results could help form methods to support weight and metabolic health.

Researchers built an artificial intelligence (AI) model that identified three types of compounds that promote healthy aging: flavonoids, omega -3 fatty acids, and organooxygens.

Scientists identified 300 gene variants, mostly involved with DNA repair, that influence female reproductive lifespan. In mice, they successfully manipulated genes linked to these variants to extend reproductive lifespan.
