This minimally invasive method delivers cerium-containing nanoparticles near hair roots deep under the skin and stimulates the formation of new blood vessels around the mice’s hair follicles to promote hair regrowth.

Six weeks of exercise changed epigenetic information of skeletal muscle cells in young men (i.e. changing how DNA is "read", which alters whether genes are turned on or off and changes their function.)

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.
