Jelly implant keeps an eye on body oxygen levels
Although smaller than a grain of rice, a phosphorescent hydrogel implant that monitors tissue oxygen could end amputations in people with blocked blood vessels or help athletes design better training programmes. The first of these tiny but durable devices has survived more than four years - implanted in the foot of the researchers who created it.
