Shuyuan Lin, Yujia Zhong et al. By Leah Crane Graphene, an atom-thick layer of carbon, has been called a miracle solution for better batteries, stronger armour, flexible electronics, and more. Now a self-healing version could do even more. Hongwei Zhu at Tsinghua University in China and his colleagues have made a graphene gel that is tough and rigid when dry, but squidgy, stretchy and self-healing when wet. They mixed graphene sheets, just a nanometre thick, with water, then added polyacrylic acid,
