2018 preview: Bioelectricity tweak can regenerate missing limbs


Jim Wehtje By Jessica Hamzelou A bold plan to regenerate missing limbs by tweaking the body’s bioelectricity could be realised in the coming year. Michael Levin and his team at Tufts University, Massachusetts, have started experiments to get mice to regrow parts of their paws. Levin’s team has already found that patterns of electrical activity allow cells to communicate with each other, and control how embryos develop. Earlier this year, the group altered this pattern – which they call the “bioelectric code” – in worms, enabling them to grow heads instead of tails and vice versa. Since then,
