The
first purely silicon oxide-based “resistive RAM” memory chip that can
operate in ambient conditions has been developed by researchers in the
U.K., and it needs just a thousandth of the energy of Flash-based chips.
Unlike other attempts to develop similar silicon-oxide chips, this
invention does not require a vacuum to operate.

With
the advent of the solid-state transistor and semi-conductor-based flat
panel display technology, the vacuum tube has virtually disappeared from
consumer electronics. But a team of researchers in Korea and at NASA’s
Ames Research Center have combined the best traits of both technologies
to create a vacuum channel transistor just 150 nm long.

In
a recent project that has challenged the notion that the best chip is
the most accurate one, a research team has unveiled this week its
prototype “inexact” computer chip. By allowing the chip to make a few
mistakes, developers were able to slash the power consumption of the
chip dramatically. The result is a chip at least 15 times more efficient
than today’s technology.

Not
long after a partially paralyzed man in Switzerland used his mind to
remotely control a small robot, a Massachusetts woman paralyzed for 15
years used only her thoughts to direct a robotic arm to pick up a bottle
of coffee and bring it to her lips But will the experimental
brain-controlled technology ever help paralyzed people in everyday life?

A
year after a researcher at Linköping University in Sweden built a fully
functional field-effect transistor from plastic, another scientist at
the same institution has shown that it is possible to control these
transistors with great precision, allowing the device to function as a
logic circuit.

Thanks
to new energy taxation regulations taking effect in Germany, electrical
engineers there have invented a space-saving energy usage metering unit
that can be simply clipped onto a power cable like a laundry peg,
without having to disconnect the load. The device is based on a magnetic
field sensor originally developed for use in washing machines, where it
monitors the position and orientation of the rotating drum.

Researchers from North Carolina State University have developed a new way to fine-tune wireless power transfer (WPT) receivers, making the systems more efficient and functional. The researchers have shown that it is possible to transmit power wirelessly by using magnetic resonance.

Camera
maker Canon Inc. is moving toward fully automating digital camera
production in an effort to cut costs—a key change being played out
across Japan, a world leader in robotics. According to the company
spokesman, counting on machines can help preserve the country's
technological power.

There's
nothing worse than a shonky pool table with an unseen groove or bump
that sends your shot off course. A new study has found that the same
goes at the nano-scale, where the "billiard balls" are tiny electrons
moving across a "table" made of the semiconductor gallium arsenide.
