Scientists forge molecular-sized scissors
We've already seen molecular elevators, keypad locks, and even spiders, but a team of scientists at the University of Tokyo have now further expanded our pint-sized toolkit, crafting a pair of molecular scissors for those hard to reach places. Apparently, the scientists used rings of carbon and hydrogen for the blades, with a "chiral ferrocene" molecule supplying the pivot point, and couple of "phenylene groups" acting as handles -- all of which adds up to to a mere three nanometers in length. To manipulate the scissors, the scientists simply alternate between shining visible light and UV rays to open and close 'em. According to LiveScience, the team's now working on a slightly larger pair of clippers that can be operated remotely, potentially for use inside the human body -- which is only a somewhat less scary prospect than a swarm of nanobots being let loose for a little autonomous repair work.
University of Tokyo crafts tea-grabbing humanoid to serve you better
If you've got a domesticated service bot around to flip your channels and chase away any uninvited intruders, there's not too much else a lonely, elderly individual needs from a fellow humanoid, but researchers at the University of Tokyo are crafting more lifelike and more agile servant bots nevertheless. In an effort to create a tactical team of droids ready and willing to serve the aging population of Japan, the team is working with Kawada Industries Inc. to create friendly robots that can assist folks with around the house chores such as pouring tea and cleaning the dishes. Several models were out and about during a recent demonstration, as one wheeled bot delivered beverages to its master, and other renditions responded to human movements and the bevy of sensors installed in the floor and sofa of a room. Essentially, the team is attempting to seamlessly integrate robotic life with our world, and they're already prepared to feel a lashing from privacy advocates who will protest the embedded camera systems that the robots feed off of. Still, we'd rather have a potentially Big Brother-equipped servant to make sure our favorite dramas get recorded than no one at all.
SHOJI to detect the mood of a room for about $3,000
If you're someone who can easily read other people's emotions, then you probably won't be getting a SHOJI (Symbiotic Hosting Online Jog Instrument) anytime soon. For the rest of us, we'll have to rely on this latest invention from our friends at the University of Tokyo and GS Yuasa. The SHOJI apparently can sense the "mood" of a room by monitoring light levels, temperature, humidity, infrared, ultrasonic waves, the "presence and movement of people," (not unlike that Mitsubishi air conditioner we saw recently) body temperature, and "the nature of activity in the room," whatever that is. All of that data is then compiled and computed to output to an LED flask sort of thing which displays red for anger, blue for sadness, yellow for happiness and green for peace. Apparently Japanese managers and hospitals are willing to pay a hefty price for this privilege, given that it'll cost between ¥300,000 and ¥400,000 ($2,500 to $3,300) when its released in April 2007. Still, the SHOJI is no KotoHana flower, that's for sure.
Japanese researchers build 512-core math coprocessor
While we're just getting used to dual-cores and have our eyes on those upcoming quad-core chips, Japanese computer scientists at the University of Tokyo have built a 500MHz 512-core math co-processor chip that can perform up to 512 billion floating-point operations per second. The Grape DR chip is designed to fit on a PCI-X card and act as a secondary chip for the main CPU. The project, which has been ongoing since 1989, expects to reach two petaflops (that's two quadrillion, or 2,000,000,000,000,000) floating-point operations per second sometime around 2008. No doubt that Intel, which is planning on an 80-core processor by 2011, is watching this research very very closely.[Via Channel Register]
