Computerized moths diversify to survive

February 11, 2002

Real birds pecking virtual moths have shown how camouflage probably evolves. The computerized prey adapted to blend into their background, and developed a wide range of different markings.
University of Nebraska biologists made virtual moths. A set of computer instructions representing an electronic genome determined their wing patterns. The researchers trained captive blue jays to hunt the moths. Pecking at an on-screen moth earned a jay a food pellet. After… read more

Computerized Combat Glove

(Brittany Sauser)

RallyPoint, a startup based in Cambridge, MA, has developed a sensor-embedded glove that allows the soldier to easily view and navigate digital maps, activate radio communications, and send commands without having to take his or her hand off their weapon.

It includes four push-button sensors, a mouse funtion, three accelerometers, and an USB connection.

Computer-Guided Nanoparticle Therapy Destroys Tumors

June 30, 2009

Polymer-coated gold nanorods completely destroyed all tumors in a nonhuman animal model of human cancer with a single dose, scientists have found.

Computer-generated robots

November 30, 2010

(Fraunhofer IPA)

Engineers at Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) have used a genetic software algorithm to automatically design moving robots.

The robots consist of cylinder-shaped tubes with ball-and-socket joints that can assume different shapes as needed. Software determines the shape of the tubes, the position of the movement points, and the position of the drives (actuators).

Computer-aided design for life itself

December 31, 2009

University of Washington scientists have developed “Tinkercell” to allow synthetic biologists to build artificial life forms, using a library of different cells, membrane proteins, fluorescent proteins, enzymes and genes to create their organism.

Tinkercell can then simulate the life form to see if it functions as expected.

Computer, Heal Thyself

July 25, 2003

Researchers from Australia’s Cooperative Research Centre for Satellite Systems have succeeded in building a computer that can repair itself in space.

The scientists used a combination of smart software and field programmable gate arrays.

In what Australian researchers believe to be a world first, FedSat’s High Performance Computing Experiment has detected a fault caused by stray space radiation, analysed the problem, and restored itself to full capability –-… read more

Computer, heal thyself

July 14, 2004

Why should humans have to do all the work? It’s high time machines learned how to take care of themselves.

“For at least three decades now, programmers have joked of ‘heisenbugs’ — software errors that surface at seemingly random intervals and whose root causes consistently evade detection.

“The name is a takeoff on Werner Heisenberg, the German physicist whose famous uncertainty principle posited that no amount of observation… read more

Computer users move themselves with the mind

September 28, 2005

Computer scientists have created a brain-computer interface that can read your thoughts. It allows you to stroll down a virtual street. All you have to do is think about walking.

The technology detects brain waves by using electrodes placed at strategic points on the scalp; they are positioned over brain areas known to be involved in moving specific body parts. The computer can then distinguish between signals corresponding to… read more

Computer traders blamed for Wall Street crash

May 17, 2010

The speed at which algorithmic trades are executed, usually milliseconds, is shrinking fast: by a factor of 10 since 2007, says Kevin McPartland at Tabb Group, due to investment in dedicated optical-fiber networks and faster routing devices.

The average execution time for one class of small trade on the New York stock exchange fell from 10 seconds to 0.7 seconds between 2005 and 2009.

“The big problem,” says… read more

Computer Screen Controlled with Monkeys’ Brain Signals

March 18, 2002

Researchers at Brown University have demonstrated that brain patterns can be used to control machines. The development could lead to techniques that allow paraplegics to articulate artificial limbs through thought alone.In the experiment, which resembled a computer game, monkeys initially used a joystick to chase red and purple dots around a screen.

Then, unknown to the monkeys, the joystick was disconnected — but the animals were still able to… read more

Computer scientists to copy brain of a mammal

July 26, 2005

IBM and Switzerland’s Ecole Polytechnique Federale de Lausanne (EPFL) have teamed up to create the most ambitious project in the field of neuroscience: to simulate a mammalian brain on the world’s most powerful supercomputer, IBM’s Blue Gene.

They plan to simulate the brain at every level of detail, even going down to molecular and gene expression levels of processing.

Computer Scientists Inject Context into Automated Image Annotation

October 18, 2007

Computer scientists from UC San Diego and UCLA have brought common sense to an automated image labeling system, using context to help identify objects in photographs.

They are using the Google Labs tool called Google Sets, which generates lists of related items or objects from just a few examples, providing contextual information that improves the accuracy of automated image labeling systems.

Computer scientists identify future IT challenges

January 26, 2005

A group of British computer scientists have proposed a number of “grand challenges” for IT that they hope will drive forward research, similar to the way the human genome project drove life sciences research through the 1990s.

Ambitious goals include harnessing the power of quantum physics, building systems that can’t go wrong, and simulating living creatures in every detail.

Computer scientists build computer using swarms of crabs

April 17, 2012


Logic gates that exploit the swarming behavior of soldier crabs have been built and tested in Japan, Technology Review Physics arXiv Blog reports.

The experiment is based on the ideas of two computer scientists — Ed Fredkin and Tommaso Toffoli — who studied how it might be possible to build a computer out of billiard balls.

The idea is that a channel would carry information encoded… read more

Computer scientist turns his face into a remote control

June 25, 2008

A UC San Diego computer science Ph.D. student can turn his face into a remote control that speeds and slows video playback.

The proof-of-concept demonstration is part of a larger project to use automated facial expression recognition to make robots more effective teachers.
