Researchers develop 'brain-reading' methods
It is widely known that the brain perceives information before it reaches a person's awareness. But until now, there was little way to determine what specific mental tasks were taking place prior to the point of conscious awareness.
That has changed with the findings of scientists at Rutgers University in Newark and the University of California, Los Angeles who have developed a highly accurate way to peer into the brain to uncover a person's mental state and what sort of information is being processed before it reaches awareness. With this new window into the brain, scientists now also are provided with the means of developing a more accurate model of the inner functions of the brain.

Western Digital Rolls Out First 1TB Laptop HHD
It certainly didn't take long for somebody to roar past Toshiba's short-lived record of 500GB for the largest available laptop storage capacity, announced on May 14.
Western Digital on July 27 introduced two new laptop drives that knocked Toshiba's Portege R600-ST4203 solid-state laptop out of the No. 1 spot: the WD Scorpio Blue drives, available in both 750GB and 1TB capacities.

How robot drones revolutionized the face of warfare
Barely an hour's drive from the casinos of Las Vegas, a group of unassuming buildings have become as important as the trenches were to WWI. The big difference? Today's warriors are fighting without getting in harm's way, using drones to attack targets in Afghanistan and Pakistan.
There are now more than 7,000 UAVs ranging from the workhorse, the Predator, and its beefier, deadlier kin the Reaper, to army drones like the tiny hand-launched Raven and the larger Shadow.

Is the ocean Florida's untapped energy source?
The answer to easing the energy crunch in one of the nation's most populous states could lie underwater.
Researchers at Florida Atlantic University are in the early stages of turning that idea into reality in the powerful Gulf Stream off the state's eastern shore.
"If you can take an engine and put it on the back of a boat or propel a ship through water, why not take a look at the strength of the Gulf Stream and determine if that can actually turn a device and create energy?

Scramjets promise space travel for all
Advanced technology is also breathing fresh life into winged spacecraft. The buzz centres on a hypersonic engine known asa supersonic combustion ramjet, or scramjet. Despite the name, scramjets are very different to the turbojet engines that power commercial aircraft, not least because scramjet-powered vehicles must first be accelerated to Mach 4 or so using jet engines or rockets before their scramjets can work. This is because, unlike turbojets, scramjets do not use spinning blades to compress the air entering the engine. Instead, the high speed of the vehicle compresses the incoming air, which is then fed into a combustion chamber where the burning fuel creates an exhaust jetthat exits the engine faster than the air that entered.

Microwave weapon will rain pain from the sky
THE Pentagon's enthusiasm for non-lethal crowd-control weapons appears to have stepped up a gear with its decision to develop a microwave pain-infliction system that can be fired from an aircraft.
The device is an extension of its controversialActive Denial System, which uses microwaves to heat the surface of the skin, creating a painful sensation without burning that strongly motivates the target to flee.

Electricity From Salty Water
A device that gleans usable energy from the mixing of salty and fresh waters has been developed by University of Milan-Bicocca physicist Doriano Brogioli. If scaled up, the technology could potentially power coastal homes, though some scientists caution that such an idea might not be realistic.
Extracting clean, fresh water from salty water requires energy. The reverse processmixing fresh water and salty waterreleases energy. Physicists began exploring the idea of extracting energy from mixing fresh and salty waters, a process known as salination, in the 1970s. They found that the energy released by the worlds freshwater rivers as they flowed into salty oceans was comparable to "each river in the world ending at its mouth in a waterfall 225 meters [739 feet] high," according to a 1974 research paper in the journal Science. But those who have chased the salination dream have collided with technological barriers.
