Plan Now for the Robot Apocalypse

You say he's wistful. I say he's plotting. (WALL-E image courtesy Disney)

Ah, lovable robots, so helpful and kind and compliant, who wouldn’t fall in love with them? And that was the gist of a popular story by Robert Ito in our current print edition. People, perhaps channeling the Sirius Cybernetics Corporation’s promise of a robot as "your plastic pal who's fun to be with," are growing inordinately fond of their mechanical friends: What happens as robots become ever more responsive, more humanlike? Some researchers worry that people—especially groups like autistic kids or elderly shut-ins who already are less apt to interact with others—may come to prefer ... Read More

Who is Bombing Mexico’s Nanotech Labs?

As if drug-war wracked Mexico didn't already have enough problems: Nature reports that  its nanotechnology research laboratories have been hit with a wave of letter bombs that have injured several people. "An eco-anarchist group calling itself Individuals Tending Towards Savagery" has claimed responsibility for most of the attacks, writes Leigh Philips. Personally, I suspect this 'group' is a lone nutcase; the tactic, the obscure and narrow range of targets, and the loquacious anti-technology screeds that accompany the bombings all echo the modus operandi of Ted Kaczynski, aka the Unabomber ...

Researchers & Discoveries: An Eye for Medicine

Babak Parviz

WHAT’S HIS DEAL? Developing microelectronic-equipped contact lenses that will be able to read vital signs, like a diabetic’s blood-sugar levels, by way of fluids on the eye. “A lot of things in the body can be monitored via chemical parameters, and a lot of them show up on the surface of the eye. This could be a fundamentally new tool for medicine.” HOW WOULD THAT WORK? Tiny sensors in the lens would continuously track glucose levels in the eye’s tear fluid, then transmit the information, via an embedded computer chip, to a doctor. Or even to the wearer, through the lens itself. ... Read More

‘Roach Motels’ for Bacteria

In the age-old battle between man and microbe, people have tried in countless ways to keep their surroundings germ-free, ranging from plain old scrubbing, heat sterilization and chemical disinfectants to high-tech solutions like irradiation or drug-eluting coatings. Now a new approach could make it easier to keep disease-causing bacteria from forming noxious invisible biofilms on surfaces. Researchers at the University of New Mexico and the University of Florida have developed polymer microspheres that trap and kill bacteria — in effect tiny antimicrobial "roach motels." Coatings ...

Toxicology of the Tiny

Already incorporated into consumer products ranging from baseball bats and clothing to sunscreens and toothpaste, engineered nanoparticles — ENPs — hold great promise in such areas as energy, pollution remediation, medicine and materials science. The nanotechnology industry is projected to be worth $1 trillion by 2015. It is all made possible by the peculiar properties of nanoparticles, which are defined as having at least one dimension measuring 100 nanometers or less (a nanometer being one-billionth of a meter, or about one one-hundred-thousandth the width of a human hair). As the ... Read More

The Public Will Walk With Nanotech — For Now

Like belching smokestacks in the 1800s, new technology once was something to be uncritically welcomed; now the public often keeps it at arm's length as a default position. Milk from an enhanced cow? No thanks. Transgenic corn for famine victims? We'll pass. Various helpful chemicals in our plastics? Pesticides that keep voracious insects off our produce? Irradiation to kill much smaller even nastier pests? Whether you view such risk-averse opponents as Luddites, prophets or something in-between, they're still out there in abundance. Nanotechnology, on the other hand, has so far avoided ... Read More

Nanotechnology: New Risks But No Rules

Barely a decade after the industry got its start, nanotechnology is poised to sweep the globe. Touted as the next industrial revolution, potential uses for nanomaterials include highly efficient solar collectors, medical devices capable of delivering medications to individual cells, odor-free gym socks and invisible sunscreen lotion. Nanotechnology fabricates and manipulates objects at a very small scale, less than 100 nanometers in size. For an idea of how small that is, a sheet of paper is 100,000 nanometers thick. A red blood cell is 7,000 nanometers across while a DNA molecule is 2.5 ... Read More

Much Ado About Nanotech

It's a quantum leap in materials science, revolutionizing manufacturing, food production and health care. Objects as small as a few dozen atoms across can be manipulated in size and shape, and function. But as nanotechnology rapidly worms its way into commerce, there has been very little government oversight addressing the risks that may accompany the breakthroughs. Experts say this is because the technology is so new and, in part, regulators are reluctant to hamper innovation. Meanwhile, manufacturers have, quietly, begun incorporating nanomaterials into all sorts of consumer products. ... Read More
