“One Scientist Cured Type I Diabetes In Rats With A Blood-Cell-Size Device Already”

Steve Martin and Richard Feynman had a similar idea: Let’s get small. As we can now put the Encyclopedia Britannica on the head of a pin, we’ll eventually place nanobots inside of people to regulate health and cure illnesses, though I will guess it’ll take substantially longer than the boldest projections. From Diane Ackerman’s new book The Human Age, via Delancey Place:

“The nanotechnology world is a wonderland of surfaces unimaginably small, full of weird properties, and invisible to the naked eye, where we’re nonetheless reinventing industry and manufacturing in giddy new ways. Nano can be simply, affordably lifesaving during natural disasters. The 2012 spate of floods in Thailand inspired scientists to whisk silver nanoparticles into a solar-powered water filtration system that can be mounted on a small boat to purify water for drinking from the turbid river it floats on.

In the Namibian desert, inspired by water-condensing bumps on the backs of local beetles, a new breed of water bottle harvests water from the air and refills itself. The bottles will hit the market in 2014, for use by both marathon runners and people in third-world countries where fresh water may be scarce. South African scientists have created water-purifying tea bags. Nano can be as humdrum as the titanium dioxide particles that thicken and whiten Betty Crocker frosting and Jell-O pudding. It can be creepy: pets genetically engineered with firefly or jellyfish protein so that they glow in the dark (fluorescent green cats, mice, fish, monkeys, and dogs have already been created). It can be omnipresent and practical: the army’s newly invented self-cleaning clothes. It can be unexpected, as microchips embedded in Indian snake charmers’ cobras so that they can be identified if they stray into the New Delhi crowds. Or it can dazzle and fill us with hope, as in medicine, where it promises nano-windfalls. …

The futurist Ray Kurzweil predicts that ‘by the 2030s we’ll be putting millions of nanobots inside our bodies to augment our immune system, to basically wipe out disease. One scientist cured Type I diabetes in rats with a blood-cell-size device already.”
