Samsung Electronics today announced that it has developed the first Solid State Disk (SSD) based on NAND Flash memory technology. The NAND-based SSD is a low power, lightweight storage media for notebook PCs, sub-notebook PCs and tablet PCs. Using the industry's highest density 8Gb NAND Flash, Samsung can build SSDs with a capacity of up to 16Gb.

The SSD has a power consumption rate less than five percent of today's hard disk drives (HDDs), enabling next generation mobile PCs to extend their battery life by more than 10 percent. The NAND-based SSD weighs less than half that of a comparably sized HDD.

Free of moving parts, the Samsung SSD memory has minimal noise and heat emission. Moreover, it is a highly reliable storage media that endures exceptionally well in environments with extreme temperatures and humidity, making it suited for industrial and military applications.

The SSD's performance rate exceeds that of a comparably sized HDD by more than 150 percent. The storage disk reads data at 57 MegaBytes per second (MBps) and writes it at 32MBps.

Researchers at the Carnegie Institution's Geophysical Laboratory have learned to produce 10-carat, half-inch thick single-crystal diamonds at rapid growth rates (100 micrometers per hour) using a chemical vapor deposition (CVD) process. This size is approximately five times that of commercially available diamonds produced by the standard high-pressure/high-temperature (HPHT) method and other CVD techniques. In addition, the team has made colorless single-crystal diamonds, transparent from the ultraviolet to infrared wavelengths with their CVD process.

The standard growth rate is 100 micrometers per hour for the Carnegie process, but growth rates in excess of 300 micrometers per hour have been reached, and 1 millimeter per hour may be possible. With the colorless diamond produced at ever higher growth rate and low cost, large blocks of diamond should be available for a variety of applications. "The diamond age is upon us," concluded Hemley.

A battery with a lifespan measured in decades is in development at the University of Rochester, as scientists demonstrate a new fabrication method that in its roughest form is already 10 times more efficient than current nuclear batteries—and has the potential to be nearly 200 times more efficient. The details of the technology, already licensed to BetaBatt Inc., appears in today’s issue of Advanced Materials.

Betavoltaics, the method that the new battery uses, has been around for half a century, but its usefulness was limited due to its low energy yields. The new battery technology makes its successful gains by dramatically increasing the surface area where the current is produced. Instead of attempting to invent new, more reactive materials, Fauchet's team focused on turning the regular material's flat surface into a three-dimensional one.

As reported over on Sportsdot, the 2005 RoboCup US Open wrapped up today in Atlanta, Georgia. The American entry from the University of Texas fell 2-0 in robot soccer to the powerhouse German squad, the MicroSoft HellHounds. After the match, the German robot dogs were programmed to flex their metal biceps. With the time to devote to development and the financial backing of a company like Microsoft, the German entries are much more polished then their American counterparts at the moment. Last month at the RoboCup German Open, the Germans dominated nearly every category.

"Microsoft is working with Ford Motor Co towards car that can't crash. The future of cars according to Gates will involve high-definition screens, speech recognition technology, cameras, digital calendars and navigation equipment with directions and road conditions." From the article: "Also on Friday, Microsoft unveiled its Performance Peak Initiative -- a line of computer systems to help the auto industry better coordinate supply chains, streamline design, production and sales and fill vehicles with computer gadgets."

A Spanish designer has come up with what could be the perfect solution for the woman who feels frustrated that she has to do all the house chores.

It is a washing machine called "Your Turn", which will not let the same person use it twice in a row.

When the sensor is then plugged into the washing machine, the software will only allow the wash programme to start if a different finger is placed on it each time.

The one thing it will not do though is something that most guys are notoriously bad at - separating the whites from the coloureds.

A new type of transistor structure, invented by scientists at the University of Illinois at Urbana-Champaign, has broken the 600 gigahertz speed barrier. The goal of a terahertz transistor for high-speed computing and communications applications could now be within reach.

The goal of a terahertz transistor was not possible using the previous device structure, Feng said. "To achieve such speed in a typical HBT, the current density would become so large it would melt the components. In our pseudomorphic HBT, we can operate at higher frequencies with less current density. With this new material structure, a terahertz transistor is achievable."

The US military is funding development of a weapon that delivers a bout of excruciating pain from up to 2 kilometres away. Intended for use against rioters, it is meant to leave victims unharmed. But pain researchers are furious that work aimed at controlling pain has been used to develop a weapon. And they fear that the technology will be used for torture.

"I am deeply concerned about the ethical aspects of this research," says Andrew Rice, a consultant in pain medicine at Chelsea and Westminster Hospital in London, UK. "Even if the use of temporary severe pain can be justified as a restraining measure, which I do not believe it can, the long-term physical and psychological effects are unknown."

The research came to light in documents unearthed by the Sunshine Project, an organisation based in Texas and in Hamburg, Germany, that exposes biological weapons research. The papers were released under the US's Freedom of Information Act.

The contract, heavily censored before release, asks researchers to look for "optimal pulse parameters to evoke peak nociceptor activation" - in other words, cause the maximum pain possible.

A small Fremont-based startup called Nanochip Inc. has developed prototype arrays of atomic-force probes, tiny instruments used to read and write information at the molecular level. These arrays can record up to one trillion bits of data -- known as a terabit -- in a single square inch. That's the storage density that magnetic hard disk drive makers hope to achieve by 2010. It's roughly equivalent to putting the contents of 25 DVDs on a chip the size of a postage stamp.

If successful, Nanochip's technology could take the $7 billion flash memory market -- which may begin to bump up against its miniaturization limits by the close of this decade -- in an entirely new direction.

Nanochip has a joint development agreement with Ovonix, a Michigan-based company that invented phase-change media, the type of thin film used on a CD or DVD read-write disc. The material has shown durability in other uses, Mr. Knight notes, citing an Intel Corp. report that the film can withstand more than one trillion "write" and "read" cycles.

Planetary rovers may soon have an eight-legged mechanized side-kick to help them explore distant planets. The Scorpion robot is able to descend steep cliffs, climb rough terrain, and squeeze into crannies that are inaccessible to larger, wheeled vehicles.

Walking robotics is a relatively new field, and engineers are taking cues from biology to give these machines versatile locomotive capabilities. The Scorpion, for example, moves by following an internally generated pattern based on the movement of its real-life counterparts. "The program has the flexibility to allow [the robot] to adapt to the environment," says Colombano. Essentially, he says, it has "reflexes that take over at the point when the motion is somehow obstructed".
