Tissue engineers have come a long way in recent years, fabricating human tissue Lego blocks, artificial kidney cells, sight-restoring bio-synthetic corneas and more. But no one has figured out how to grow large amounts of transplantable tissue in the lab, because it’s too difficult to keep it alive. Texas researchers may have an answer: Use a common laxative to grow some blood vessels.
Future stitches could be made out of your own muscle cells, ensuring proper re-growth of injured muscle tissues.
Researchers in Massachusetts are implanting injured mice with microthreads coated with human muscle cells, reports Technology Review. The threads are made of the same proteins the human body uses to heal wounds, and when seeded with muscle cells, they act as a scaffold for the construction of healthy tissue.

In the annals of organized arm wrestling, there had never been a match like this. Ever since 1952, when the first official arm-wrestling competition took place at Gilardi´s Saloon in Petaluma, California, contestants have generally been large men with unusually muscular forearms. But on this Monday afternoon, the TV cameras focus on a slim 17-year-old girl.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
