Current Event #3

Biotech scientists have engineered electronic skin that can sense touch like artificial limbs. The nano skin responds to almost the same pressures as human skin. It's an advance towards replacing today's clumsy robots and artificial arms with smarter, touch-sensitive upgrades so that if you lose a limb you can still use your new one as if you never lost it. "Humans generally know how to hold a fragile egg without breaking it," said Ali Javey, an associate professor of computer sciences at the University of California at Berkeley, who led one of the research teams. If we ever wanted a robot that could unload the dishes, for instance, we'd want to make sure it doesn't break the wine glasses in the process. But we'd also want the robot to grip the stock pot without dropping it. The "e-skin" made by Javey's team comprises a matrix of nanowires made of germanium and silicon rolled onto a sticky polyimide film." The prototype, measuring 49 square centimetres (7.6 square inches), can detect pressure ranging from these things typing on a keyboard or holding an object. Even routine daily actions, such as brushing one's teeth, turning the pages of a newspaper or dressing a small child would easily defeat today's robots ability's but when they finally complete the nano skin they can help people to do all these things they could even get robots to do this for parents instead of hiring baby-sitters. This nano skin would be especially useful in applications where we want to send robots into environments, including space, where it could be dangerous for humans to go," said Bao. "They could collect information and send it back. It could be also used to do police force if the had to go out on an armed robber or something, or the army.

Video Chemaical Reactions

  In this video it shows the chemical reaction with alcohol and Bromine what happens is that the alcohol makes the Bromine dissolve releasing a red gas that fumes up when the gas disapers  the block of Bromine is gone.

In this video it shows the reaction of lithium and and water the reaction is when lithium starts burning after contact with water.

In this video it's another alkali metal cesium it is almost the same reaction but instead of burning it blows up like fireworks.
http://www.youtube.com/watch?v=qRmNPKVEGeQ&NR=1
In this video it is Potassium and water it is an alkali metal its a mixture of the 2nd and 3rd video because it burns while releasing the firework like sparks

http://www.youtube.com/watch?v=vJslbQiYrYY&NR=1
In this video it is sodium and potassium in water, The sodium stars burning and then explodes into a ball of flame, with the potassium the throw it into the jar and instley just blows up after the reaction you can see the water changes from green to purple.

In this video the throw liquid nitergien  in to a swimming pool and it and it creates a fog like gas across the pool because of the differnce of the temperature and the difference in the pool it spreads then a guy jumps into it and it goes even more.

In this video the but the cleaning liquid "The Works" and aluminum foil it creates foam from the beaker and it starts to spread all over the container and then slows down after two minutes.

In this video the but a gummy bear in oxide and it burns inside of the beaker.

In this last video they add food dye to water and put a flash light up to it in a dark room and then add salt crystals and Mineral  Turpentine and it creates It starts to smoke and it looks like there are little glowing shapes moving in the water.
