Nanotechnology-infused material is completely water resistant

Nanotechnology-infused material is completely water resistant

Now this is pretty interesting. If nanotechnology news gives you the warm fuzzies then you'll be pleased to learn that some chemists at the University of Zurich have created a new fabric that can't ever get wet. Ever. I mean, it was in water for two months and it's still not wet!

This material is made from polyester which were covered with 40nm-wide silicone nanofilaments. Since these filaments are so tiny and so spiky, they make it so water actually sits above the material in a sort of pocket. This is a permanent state. The material won't ever be made wet.

So what are the potential applications of this technology? Well, it reduces drag in water by up to 20%, for one. It can also serve as a self-cleaning cloth. Regardless of how it ends up being used, this is still pretty cool and presents numerous opportunities.

iPosture keeps you standing tall

iPosture keeps you standing tall

Sitting at the computer all day not only strains your eyes--it hurts your back. That's why Moacir Schnapp and his wife, Dr. Elma Schnapp, developed the iPosture, which is meant to remind you to sit up straight.

The device is rather small and can be worn on the skin with an adhesive patch, or clipped to a bra strap or shirt. It works by means of nanosensor technology. the microchip within the iPosture can actually monitor the angle of your upper chest and will vibrate when it detects a three degree change from your "ideal stance."

The iPosture will cost about $99.95, but it could be well worth it. The researchers say you may only need to wear the device four hours a day for two to four weeks, initially at least, to train your body into its new upright position.

Rat neuron-infused robot learns, avoids obstacles

Rat neuron-infused robot learns, avoids obstacles

A group of scientists at Reading University in the UK have developed a robot that is controlled by rat neurons. In case you're wondering why anyone would take rat brain cells and stuff them in a robot, the answer is simple: to learn more about the human brain, how it works and potentially make progress in the battle against degenerative diseases such as Alzheimer's.

Invisible material could make objects ‘disappear’

Invisible material could make objects ‘disappear’

The purported "invisibility cloak" has been in the news before. However, University of California at Berkley researchers are on the cusp of something big. They've developed a material "that can bend light around 3D objects" in effect, causing them to disappear.

Now, of course this material currently only exists on a nano scale. But these recent developments could potentially one day be scaled up to create great expanses of the material that could conceal objects and even people.

Nanoantenna Skin to provide next-gen PC cooling

Nanoantenna Skin to provide next-gen PC cooling

If you're looking for the next generation of PC cooling technology or consumer electronic recharging, you may only have to look so far as a group of researchers at the U.S. Department of Energy's Idaho National Laboratory who have developed a flexible solar cell. This cell could be applied to all sorts of electronics to make recharging a snap and cooling devices a breeze.

Flexible Material Makes For Stretchy Electronics

Flexible Material Makes For Stretchy Electronics

It looks like the dream of flexible and stretchy electronics will come true sometime in the semi-near future. A group of scientists at the University of Tokyo have recently developed a material that both conducts electricity and is made of a rubbery material that can be stretched to more than twice its size.

Hitachi is at it again, making all the other HDD manufacturers look bad with their 4TB HDDs

Hitachi is at it again, making all the other HDD manufacturers look bad with their 4TB HDDs

That’s right, by 2011 your laptop could have a 1TB HDD and your desktop could have a 4TB HDD. That’s all thanks to some nanotech thing that Hitachi has done that reduces Nanometer Recording by two times.

You could actually see the technology as early as 2009, but probably not quite in those capacities. Basically what they did was shrunk the head (I KNEW IT WAS ALL VOODOO!) to a point where it’s about 2,000 times smaller than a human hair.

Reach for the Robo-Raid: Bionic Hornet brings nanotech to war

Reach for the Robo-Raid: Bionic Hornet brings nanotech to war

I'm in two minds about this story - impressed, because nanotechnology is cool and tiny robots are even cooler, but more than a little disturbed at the idea of killer robots flying around and zapping people in the neck.  Reuters is reporting that Israel are developing a bionic hornet that could chase, photograph and eventually kill enemy combatants or terrorists.  Able to navigate tightly confined areas and so small as to be difficult to target by traditional weaponry, the concept is expected to reach prototype stage within three years. 

It's uncertain as yet whether the robots would be remotely controlled or have some sort of AI, though a combination of both is perhaps most likely; general targeting by remote, while short-range sensors automatically manage obstacle avoidance, tracking and flight.
