Long assumed to be destructive to tissues and cells, “free radicals” generated by the cell’s mitochondria—the energy producing structures in the cell—are actually beneficial to healing wounds.
That’s the conclusion of biologists at UC San Diego who discovered that “reactive oxygen species”—chemically reactive molecules containing oxygen, such as peroxides, commonly referred to as free radicals—are necessary for the proper healing of skin wounds in the laboratory roundworm C. elegans.

The evolution of worms, insects, vertebrates and other “bilateral” animals—those with distinct left and right sides—from less complex creatures like jellyfish and sea anemones with “radial” symmetry may have been facilitated by the emergence of a completely new "operating system" for controlling genetic instructions in the cell.
