Submission + - Electrical charge helps re-grow body part

MattSparkes writes: "Tadpoles can regenerate their tails thanks to a technique that alters the electrical properties of their cells, a new study shows. The build-up of electrical charge at the site of amputation helps guide tissue regeneration. They speculate that doctors might one day be able to regenerate tissue in patients — such as those who have suffered spinal cord injury, or even those who have lost fingers — by altering the flow of positively charged molecules out of cells."
