Unmanned Drones have become synonymous with destructive bombings of remote places. They were recently made famous due to the various attacks by US on hilly Afghanistan territories. It was unveiled at CES 2010 and caused a sensation there even without a demo. It has a shape like a flying saucer and is named the A.R. Drone where A.R- Stands for augmented reality. The makers (Parrot) gave a live demonstration near their office on the Canal Saint-Martin in Paris.
Unsuspecting commuters watched in awe as the “Quadricopter”(As the company calls it) zipped and zoomed past them. It was demonstrated by one of the 10 engineers who spent the last four years working on this drone. It’s easy to control as the engineer pressed one button to make the Drone hover above the ground right over the canal. He maneuvered it expertly to swing it around trees and bushes and park benches by just tilting his iPhone sideways.

LG Display Develops Flexible E-newspaper Screen
LG Display has developed a flexible electronic-paper screen that's almost as large as a tabloid newspaper, it said Thursday.
The screen measures 25 centimeters by 40 centimeters, which translates into a 19-inch diagonal screen size, and is 0.3 millimeters thin so it can bend. LG Display managed to make it flexible by utilizing a metal foil instead of the more traditional glass substrate. The South Korean company said the screen is the largest flexible e-paper display yet produced.
Electronic paper has already been put to use in e-book readers like Amazon's Kindle and Sony's Reader devices. It boasts a high-contrast ratio that makes it easy to read and relies on ambient light so doesn't cause eye strain over long periods of use. Additionally it only requires power when the screen is refreshed so e-paper devices typically have a long battery life.

Show The World What You're Drinking, With The Cipher Drinking Glass
While it's just a concept for now, designer Damjan Stankovic can send them off on the production line. The Cipher Drinking Glass has a multitude of colored dots in a seemingly random pattern, but once liquid is added, the dots actually spell out what sort of drink it is. You can see from the picture that it recognizes orange juice, milk and Coca Cola—but I wonder if it would detect the difference between vodka and gin?

India's Mobile Subscriber Base Crosses 500 Million Mark
India's mobile subscriber base crossed the 500 million mark in November, according to data released Wednesday by the Telecom Regulatory Authority of India (TRAI).
The country had crossed the 500 million mark in both fixed and wireless telephone subscribers at the end of September.
The total number of mobile subscribers was 506 million at the end of November, up from 488 million in October. About 43 out of every 100 Indians now have mobile connections, according to TRAI.
The country added 17.7 million mobile subscribers in November, following deep tariff cuts by established players and new rollouts by existing and new operators.

First Live Tweet From Space: Space Station Enters 21st Century
When Samuel Morse demonstrated the telegraph, he famously tapped out a line from the Bible: "What hath God wrought?"
When Alexander Graham Bell tested his telephone, he called his assistant: "Mr. Watson, come here, I want to see you."
When T.J. Creamer sent the first direct upload from space to the Web this morning, it looked like this:
"Hello Twitterverse! We r now LIVE tweeting from the International Space Station -- the 1st live tweet from Space! :) More soon, send your ?s"
Yes, it was the first live tweet from orbit. It may surprise you to know that space station astronauts -- who go around the world once every 91 minutes -- have not had the ability to surf the World Wide Web until now. They could send and receive digital packets -- e-mail -- but they didn't carry the software for web access until station crew member Timothy J. (T.J.) Creamer got to work on it.He's been orbiting with four crew mates since Dec. 20 and is due home in May.

Batteries built out of paper
Well, this time we made batteries out of paper. check this first news on your school blog
Researchers at Stanford University have used nanotechnology to create lightweight, bendable batteries out of paper .
The paper batteries are designed to be folded, crumpled or even soaked in an acidic solution and still work, according to Yi Cui, assistant professor of materials science and engineering at Stanford. The team created the batteries by coating a sheet of paper with ink made of carbon nanotubes and silver nanowires.
Stanford offered no indication of when the batteries might be ready for commercial use.
The striking aspect of the development is "how a simple thing in daily life -- paper -- can be used as a substrate to make functional conductive electrodes by a simple process," said Peidong Yang, professor of chemistry at the University of California, Berkeley, in a statement.
The nanotubes used in the paper batteries and supercapacitors have a very small diameter, which enables the ink made from them to stick tightly to the paper. The university noted that the paper supercapacitors may be able to handle 40,000 charge-discharge cycles, which is an order of magnitude more than lithium batteries can withstand.
Cui pointed out that the nanomaterials make better conductors than traditional materials because they can move electricity more efficiently.
This is just the latest report of scientists using nanotechnology to further battery research.
