First paper-based transistors

July 23, 2008

Portuguese researchers have created the first field effect transistors (FET) with a paper interstrate layer.

Possible applications include new disposable electronics devices, such as paper displays, smart labels, bio-applications, and RFID tags.

Regeneration Sans Stem Cells

January 30, 2006

Scientists are developing drugs to regenerate human tissues and organs, avoiding medical problems like immune rejection.

Proteins produce nano-magnetic computer memory

April 28, 2003

Computer hard drive capacity could be increased a hundredfold by using the protein apoferritin (the main molecule in which iron is stored in the body) to fabricate nanoscale magnetic particles, claims UK company Nanomagnetics.

Each particle can store a bit of information; they can be packed onto a disk drive at much greater density than with existing hard disk manufacturing methods.

IMEC team shows wireless ‘thought-to-text’ cap

March 24, 2010

Belgium and Netherlands researchers have developed a “thought-to-text” device that, it is claimed, could enable people suffering from paralysis or speech or language disorders to communicate.

The “Mind Speller” device detects and interprets P300 event-related potentials in the EEG signals of a person that is selecting characters from a display presenting alternate rows and columns of characters.

Unlike available P300 devices, which are large, expensive and uncomfortable in… read more

Scientists create first free-standing 3D cloak

January 31, 2012


Researchers led by the University of Texas at Austin have cloaked a three-dimensional object standing in free space, bringing the invisibility cloak one step closer to reality.

The researchers used “plasmonic metamaterials” to hide an 18-centimeter cylindrical tube from microwaves.

When light strikes an ordinary object, it rebounds off its surface towards another direction, just like throwing a tennis ball against a wall. The reason we… read more

Lithium-Ion Batteries for Less

July 29, 2008

A University of Texas at Austin materials engineering professor has demonstrated a microwave-based method for making lithium iron phosphate that takes less time and uses lower temperatures than conventional methods.

That could translate into a lower cost and safer alternative to the lithium cobalt oxide used in most lithium-ion batteries in laptop computers.

Robot moved by a slime mould’s fears

February 13, 2006

Kobe University researchers have developed a slime mold-controlled bot in an effort to find simpler ways to control a robot’s behavior in a complex or paradoxical environment.

They grew slime in a six-pointed star shape on top of a circuit and connected it remotely, via a computer, to the hexapod bot. Light sensors on top of the robot controlled light shone onto one of the six points of the… read more

Man or Machine? (Part 1 of 3): Human or Robot?

May 6, 2003

Pattern recognition is what Ray Kurzweil calls the heart of human intelligence. “Ultimately, our machines will have equal and, in fact, even greater powers of pattern recognition,” he says.

He predicts as we reach a greater understanding of the brain, artificial intelligence will advance even more. “We’ll be able to essentially recreate the powers of human intelligence and combine them with the speed, accuracy and knowledge-sharing ability of machines.”

Life-drawing robot could teach us about art

April 2, 2010

Hawking by Aikon

University of London computer scientists have developed an algorithm that attempts to recreate the thought process used by a portrait artist by drawing lines (based on a digital photo).

The team hopes to reveal the fundamental components of creativity and have Aikon develop its own critical sense and decide whether to keep or erase its own pen strokes.

Facebook malware scam takes hold

February 6, 2012

More than 60,000 users of Facebook users are sharing a link to a malware-laden fake CNN news page reporting the U.S. has attacked Iran and Saudi Arabia, security firm Sophos said Friday.

If users who follow the link then click to play what purports to be video coverage of the attack, they are prompted to update their Adobe Flash player with a pop-up window that looks very much… read more

Pneumatic robot arranges limbs for MRI ‘sweet spot’

August 4, 2008

A pneumatic robot that positions patients’ limbs inside an MRI scanner allows physicians to exploit a bizarre phenomenon where hard-to-see tendons jump into sharp focus when held at the right angle.

Enzyme computer could live inside you

February 24, 2006

A molecular computer that uses enzymes to perform calculations has been built by researchers in Israel.

They believe enzyme-powered computers could eventually be implanted into the human body and used to, for example, tailor the release of drugs to a specific person’s metabolism.

Connections to Broadband Increase 50%

May 20, 2003

The number of American households that connect to the Internet via broadband cnnections grew by 50 percent in the last year, raising to nearly one-third the portion of home Internet users who now use broadband connections. But the rapid growth rate is unlikely to continue.

Printed cells to treat burn victims

April 13, 2010

Science US Wounds Printer

A new “bioprinter” medical device that works like an inkjet printer is being developed by Wake Forest Institute of Regenerative Medicine to heal burns and other wounds by “printing” skin cells directly onto the wound, reducing the need for skin grafts.

Cutting-edge MRI techniques for studying communication within the brain

February 9, 2012

White matter (WM) tract reconstructions (credit: Andrew L. Alexander et al./Brain Connectivity)

Researchers from the University of Wisconsin, Madison have presented innovative magnetic resonance imaging (MRI) techniques that can measure changes in the microstructure of the white matter likely to affect brain function and the ability of different regions of the brain to communicate.

Brain function depends on the ability of different brain regions to communicate through signaling networks that travel along white matter tracts.

Using… read more
