future of medicine

As much as we love the actual future here at Popular Science, we love the past's vision of the future almost as much. So we basically freaked out when our good friends over at Pink Tentacle discovered this spread from a 1969 issue of the Japanese magazine Shonen Sunday.

These pictures show a predicted 1989 where computers have changed how we live. The above photo depicts a classroom full of children learning on computers, watching a video of a teacher, and receiving beatings from enforcement robots.

Researchers at the University of Florida claim to be the first to use targeted gene manipulation to take adult stem cells and change them into another kind of cell completely. They changed the stem cells, from bone marrow in this instance, into retinal cells. These retinal cells, when injected into blind mice, helped cure their blindness.

This is not your typical light show. The neon light piping into the brain of a mouse with Parkinson's disease stops the animal's tremors instantly. Neuroscientist and psychiatrist Karl Deisseroth and his colleagues at Stanford University believe the laser light can "turn on" damaged or inactive brain cells.

Researchers in Australia have come up with an outwardly simple but incredibly ingenious way of curing blindness caused by corneal damage: Take everyday contact lenses, already used by millions (including me), and infuse them with a patient's own stem cells. After wearing them for about 2 weeks, test subjects reported a seemingly miraculous restoration of sight. Is it that easy?

A company called Tengion announced recently that its full-size, neo-bladder replacements performed well in large animal models. Tengion's technology - the commercialized version of the work of Anthony Atala - is based around the idea that it's better to use the patient's own cells to try to grow replacement organs and tissues, since transplants from donors often lead to rejection.
