Scientists at Stanford have developed helicopters powered by artificial intelligence. This invention enables the helicopters to fly themselves without the help of a pilot. Helicopters powered by artificial intelligence can fly themselves by watching what other helicopters are doing. This invention is a great stepping stone to success of developing autonomous helicopters and will advance even further.

Autonomous helicopters were there even in the past, but the functionalities were very much limited. Those copters were unable to control or fly in abrupt in environmental circumstances. Intelligent helicopters however, can handle all tasks efficiently. Advanced copters of these types powered by artificial intelligence are capable of handling various functions such as rolls, loops, tail slides etc.

Numerous algorithms govern the functionalities of intelligent helicopters and the entire team is led by Professor Andrew NG. These types of helicopters are going to define new dimensions in autonomous helicopter systems and are raking up global interest.

MIT Media lab has come up with a very latest invention of robots with facial expressions. The robot is able to make some facial expressions like lifting of eye brows with anger or surprise. Also, the robot can make other expressions when communicating with people and is the true face of interactive bots.

This achievement of MIT Media labs is termed as NEXI which is intended to be described as next generation robots. Next generation robots will be able to perform a wide variety of applications including personal interactions.
The face design as well as head design of NEXI robots were done by Xitome designs, which is a development company. The neck of robot has freedom of flexibility and it can turn or tilt its neck a maximum of four degrees. The face itself is highly innovative as the eyes, eye brows, eye lids and other parts of face are designed creatively and aesthetically.

4G technologies or fourth generation technologies are the technologies used for fourth generation wireless communication technologies. Fourth generation wireless technologies are designed to serve wireless needs on a full-fledged IP based mechanism. The key features of 4G technology is the ability to communicate in very high speed and the enhanced security.

Another important feature of 4G technology is the ability to facilitate high quality video transmission. 4G technology powered machines will be able to download movies or songs at tremendous speed in a real time environment.

The transmission rates of data on mobile phones are expected to cross 20 mbps and it could be estimated that the data transfer rate of 20 mbps is approximately ten times faster to 3G mobile broad bands. As far as connection seeds are concerned, the performance of 4G will be approximately 200 times faster to current 2G mobile broad bands and approximately 15 times faster than any ASDL service.

Stuart Parkin- a former IBM think tank is now developing a three dimensional memory system which is good enough to replace all two dimensional memory systems. In fact, all memory systems are two dimensional at present, but a three dimensional memory system implemented with the help of nano wires will define next generation memory chips and hard drives.

If you go for a comparison, you would find that this race track memory system has a very huge storage capacity when compared to magnetic tapes and speed is lot higher when compared to flash chips. When comparing the performance of racetrack chips, one would find that it is way ahead or superior to magnetic tapes and flash chips. All is done with the help of a set of nano wires, arranged in U shape adjacent to each other. Electric current is passed through the wires which produce desired effects helpful for reading and writing data.

Mr. George Whitesides, professor at Harvard University has developed a diagnostic tool which is very easy to use and absolutely cheap to afford. This tool of Prof. George is turning out be very much useful and scientific world consider this invention as a boon to mankind since, the cheap diagnostic tool can prove to be immensely helpful for millions of poor people around the globe. Coupling two technologies-one being the most modern and the other being the oldest ever, the professor defines a solution which is very much practical.

The professor uses the wide opportunities in micro fluidics and the usage of paper to derive at a unique solution. The device has only the size of a postage stamp and is made of paper. The square shaped material obviously has edges, and these edges when dipped into a blood sample will collect it soon and route it to the channels for testing.
