Korean Robot Makers Walk Off With $2 Million Prize

Korea

A team of roboticists from the Korea Advanced Institute of Science and Technology claimed a $2 million prize  that was offered by a Pentagon research agency for developing a mobile robot capable of operating in hazardous environments.

Nigerian student solves 30-year-old maths equation

A Nigerian student has broken a 30-year-old maths equation and achieved the highest grades at a univeristy in Japan for 50 years. Ufot Ekong, who studied at Tokai University in Tokyo, achieved a first class degree in electrical engineering and scored the best marks at the university since 1965, the Flotilla Magazine reported.

20 billion nanoparticles talk to the brain using electricity

Nanoparticles can be used to stimulate regions of the brain electrically, opening up new ways to treat brain diseases. It may even one day allow the routine exchange of data between computers and the brain.

A material discovered in 2004 makes this possible. When “magnetoelectric” nanoparticles (MENs) are stimulated by an external magnetic field, they produce an electric field. If such nanoparticles are placed next to neurons, this electric field should allow them to communicate.

Hypersonic air vehicle?

What is a scramjet?In a “scramjet,” or Supersonic Combustion Ramjet, the oxygen needed by the engine to combust is taken from the atmosphere passing through the vehicle rather than from an onboard tank. Researchers predict scramjet speeds could reach 15 times the speed of sound. An 18-hour trip to Tokyo from New York City becomes a 2-hour flight.

A Computer That Runs On Water

Computers and water typically don’t mix, but a team of bioengineers at Stanford have built a synchronous computer that operates using the unique physics of moving water droplets. The work combines expertise in manipulating droplet fluid dynamics with a fundamental element of computer science – an operating clock.

Because of its universal nature, the droplet computer can theoretically perform any operation that a conventional electronic computer can crunch, although at significantly slower rates.

 Using Viagra In The Fight Against Malaria?

An In vitro (outside the body) study has revealed that Viagra could also prevent malaria transmission as it stiffens red blood cells infected with malaria. This should cause them to be removed from the blood by the spleen as part of its role in destroying old red blood cells and preventing them from being taken up by mosquitoes when they bite. While this would not treat malaria in those already infected, it could reduce the disease’s spread.
