Tracking packages and food sources would lead to faster recalls and lessen contamination risks

If a natural pathogen, or a perpetrator, contaminates food, lives will be saved if the tainted product can be quickly detected, then traced back to its point of origin so the rest of the batch can be tracked down or recalled. The following technologies, in development, could help:

Microfluidic Detectors—Botulinum bacteria produce the most poisonous toxin known. They and similar agents, such as tetanus, could be detected during food processing by microfluidic chips—self-contained diagnostic labs the size of a finger. The University of Wisconsin–Madison is crafting such a chip, lined with antibodies held in place by magnetic beads, that could detect botulism during milk production. The chip could sample milk before or after it was piped into tanker trucks that leave the dairy and before or after it was pasteurized at a production plant. Other chips could detect other toxins at various fluid-processing plants, such as those that produce apple juice, soup or baby formula. [ read more ]

It’s the ultimate revenge of the nerds as product developers use their big brains to create sex machines that kick pleasure into overdrive. In fact, the very nature of the sex “toy” is changing as a new generation of sex-positive engineers infiltrates the industry.

From the smooth, silent glide of the Monkey Rocker Tango to Le Chair’s ability to put two people into a dozen compromising positions, the new products and prototypes unveiled at this week’s Adult Novelty Expo straddle the line between toy (a passive, frivolous object) and machine (a substantial apparatus that inspires commitment and even emotional attachment).

Here are some of the most interesting. [ read more ]

Swiss auto tuner Rinspeed is rolling into the Geneva Motor Show with a wild shape-shifting, iPhone-controlled electric concept car that adapts to suit the number of passengers.

At the touch of an iPhone app, the streamlined rear end of the one-seater pops up to make room for two more people. The adjustable rear end conserves energy by maximizing aerodynamics. The idea, company founder Frank Rinderknecht says, is to create lightweight, streamlined and efficient zero-emissions “individual mobility” that can adapt to suit the driver’s needs. The iPhone controls everything from the canopy – there are no doors – to the ignition. [ read more ]

Green is the new black — and bamboo is the new titanium. After years of churning out glossy, metal-finish, high-polish products, electronics companies are taking their design cues from nature — and trying to pick up the sheen of eco-friendliness — by wrapping their products in bamboo veneers.

Bamboo has become the “it” material for many gadget designers. PC maker Dell has launched its Studio Hybrid PC with the option of a bamboo case, while Asus offers a Bamboo series notebook. There are also bamboo speakers, a keyboard, mouse and USB hub available, all wearing the woody-stemmed grass. [ read more ]

msnbc.msn.com: Similar technology marketed as a way to control video games by thought

Vocal cords were overrated anyway. A new Army grant aims to create email or voice mail and send it by thought alone. No need to type an e-mail, dial a phone or even speak a word.

Known as synthetic telepathy, the technology is based on reading electrical activity in the brain using an electroencephalograph, or EEG. Similar technology is being marketed as a way to control video games by thought. [ read more ]

When geologists wanted a better look at a Yosemite rock face in years past, they only had one option: climb the cliff.
But now, thanks to super-high resolution gigapixel images created by a team of 70 photographers using GigaPan robotic imagers and a laser-mapping airplane, park geologist Greg Stock now has unprecedented access to the geological features of one of the world’s most famous parks. And all from the comfort of his laptop.

Picture this: you’re sat down for the Football World Cup final, or a long-awaited sequel to the “Sex and the City” movie and you’re watching all the action unfold in 3-D on your coffee table.

It sounds a lot like a wacky dream, but don’t be surprised if within our lifetime you find yourself discarding your plasma and LCD sets in exchange for a holographic 3-D television that can put Cristiano Ronaldo in your living room or bring you face-to-face with life-sized versions of your gaming heroes.

The reason for renewed optimism in three-dimensional technology is a breakthrough in rewritable and erasable holographic systems made earlier this year by researchers at the University of Arizona. [ read more ]

Materials made from nanotubes could lead to conformable computers that stretch around any shape.

By adding carbon nanotubes to a stretchy polymer, researchers at the University of Tokyo made a conductive material that they used to connect organic transistors in a stretchable electronic circuit. The new material could be used to make displays, actuators, and simple computers that wrap around furniture, says Takao Someya, a professor of engineering at the University of Tokyo. The material could also lead to electronic skin for robots, he says, which could use pressure sensors to detect touch while accommodating the strain at the robots’ joints. Importantly, the process that the researchers developed for making long carbon nanotubes could work on the industrial scale. [ read more ]

Invented by American computer scientists during the 1970s, the Internet has been embraced around the globe. During the network’s first three decades, most Internet traffic flowed through the United States. In many cases, data sent between two locations within a given country also passed through the United States.

Engineers who help run the Internet said that it would have been impossible for the United States to maintain its hegemony over the long run because of the very nature of the Internet; it has no central point of control. [ read more ]

Jeff Lichtman hopes to elucidate brain development and disease with new technologies that illuminate the web of neural circuits.

Displayed on Jeff Lichtman’s computer screen in his office at Harvard University is what appears to be an elegant drawing of a tree. Thin multicolored lines snake upward in parallel, then branch out in twos and threes, their tips capped by tiny leaves. Lichtman is a neuroscientist, and the image is the first comprehensive wiring diagram of part of the mammalian nervous system. The lines denote axons, the long, hairlike extensions of nerve cells that transmit signals from one neuron to the next; the leaves are synapses, the connections that the axons make with other neurons or muscle cells.
