POPSNew You By 2018 Therapeutic: Cloning for tissue replacement is already happening, as stem cells have successfully grown new heart tissues in patients. Researchers believe replacing muscle, bone, skin; even neurons, teeth, eyes, and other organs could be in beginning stages by 2018. Augmentation: Procedures expected to be in place by as early as 2015 include improved memory recall, simultaneous language translation, long range and microscopic vision on demand, wide spectrum hearing, distinctive voice projection, and stronger muscles. And by mid-to-late-2020s, “nanobots” monitoring each of our cells could keep us ageless and forever healthy.
