Endogenous Bioelectric Gradients Guide Limb Regeneration in Axolotls Without Genetic Modification
Nature Bioelectricity · Feb 2026 · DOI: 10.1038/s41594-026-0412-7
Researchers at Tufts mapped the precise voltage gradients that govern axolotl limb regrowth — and showed that externally mimicking those gradients can induce partial regeneration in frog tissue, a species that normally cannot regenerate limbs at all.
At Tufts, researchers found that voltage patterns in the hours after amputation, not genes or tissue type, predict whether a frog regrows a limb or forms a scar.

Axolotls regrow limbs by generating their own electric currents at the wound site, and researchers are learning to steer that process with drugs and fields instead of genes.
Bacteria pulse with potassium waves, planaria rewrite their anatomy through voltage, and researchers are learning to read these signals as computation, not metaphor.
New decomposition methods reveal that a single skin conductance spike is often several overlapping sweat gland bursts, complicating what wearables call a stress signal.
Researchers are using light-gated ion channels to stop cardiac fibrillation in animal hearts, replacing the defibrillator's violent shock with a patterned pulse of light.
UC San Diego researchers found bacterial biofilms use potassium ion channels to fire long-range electrical waves, coordinating metabolism the way neurons coordinate a nervous system.
