Could black holes be portals to other universes?

April 30, 2007

The objects scientists think are black holes could instead be wormholes leading to exotic cosmic locales, a new study argues.

Movie tests Asimov’s moral code for robots

July 19, 2004

Even if researchers are ever able to build robots with enough intelligence to comprehend Asimov’s laws, they are unlikely to be implemented.

Although they attracted some interest in the early stages of AI research, the rules were quickly abandoned as too prescriptive and simplistic.

“They stem from an innocent bygone age, when people seriously thought that intelligence was something that could be ‘programmed in’ as a series of… read more

Quantum networks advance with entanglement of photons, solid-state qubits

August 5, 2010

A team of Harvard physicists led by Mikhail D. Lukin has achieved quantum entanglement of photons and solid-state materials, allowing for communication of qubits over long distances in a quantum network.

Quantum networking applications such as long-distance communication and distributed computing would require the nodes that process and store quantum data in qubits to be connected to one another by entanglement, a state where two different atoms become indelibly… read more

3D Display Offers Glimpse of Future Media

November 10, 2008

A 3D display system, developed by University of Southern California researchers, could one day transform visual entertainment.

The 3D display can project both virtual as well as real images from a recorded movie, is autosterescopic (viewers don´t need to wear special viewing glasses to see the 3D effects), and is also omnidirectional, so that multiple viewers can watch the display from all directions and heights.

India Looks To Produce World’s First $10 Laptop

May 6, 2007

India’s Ministry of Human Resource Development, with help from Semiconductor Complex, a state-sponsored designer and manufacturer of integrated circuits, has developed designs for a laptop that would cost about $47, while a $10 system remains the ultimate goal.

Nanoimprint lithography gets smaller

July 30, 2004

Princeton University researchers have shown that photocurable nanoimprint lithography (P-NIL) can produce lines of polymer resist just 7 nm wide with a pitch (or pattern repeat) of only 14 nm. The technique also produced reliable results over the whole area of a 4 inch wafer.

“This work really pushes the limit down to a few molecules in size,” said Stephen Chou of Princeton.

This is a 20-fold reduction… read more

Dilbert Discovers the Singularity

November 16, 2008

“Our spam filter became self-aware and rewrote our business plan…. Do you think you really think we need to build a killer robot because our spam filter ordered you?”

Sizing up the coming robotics revolution

May 16, 2007

“There are four research topics that, as we make progress on each one, will enable our robots to do a lot more,” says Rodney Brooks is the Panasonic professor of robotics at MIT and the director of its Computer Science and Artificial Intelligence Lab.

“And so I have set these goals: the object recognition capabilities of a 2-year-old child, the language understanding of a 4-year-old, the manual dexterity of… read more

Researchers boost efficiency of multi-hop wireless networks

April 20, 2012

Multi-hop wireless networks can provide data access for large and unconventional spaces, but they have long faced significant limits on the amount of data they can transmit. Now researchers from North Carolina State University have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent.

The approach also makes the network more energy efficient,… read more

Probe Set to Test Einstein Theory

August 11, 2004

NASA’s Gravity Probe B spacecraft will test Einstein’s general theory of relativity.

Gravity Probe B will test two concepts of the theory: that Earth — and almost any body in space — creates a dimple in the universe’s space-time fabric; and that the rotation of the Earth twists that fabric.

It will attempt to measure those effects by aligning itself with a distant star and then measuring tiny… read more

Google Personalizes Search with SearchWiki

November 21, 2008

Google has introduced a new feature called SearchWiki that will allow people (in a gradual rollout to all users) to modify and save their results for specific Google searches.

They can move the sites that appear in rankings up or down, take them out altogether, leave notes next to specific sites (which are public) and suggest new sites that are not already in the results (or are buried too… read more

The Brain: Malleable, Capable, Vulnerable

May 28, 2007

In the new book, “The Brain That Changes Itself,” Dr. Norman Doidge offers a fascinating synopsis of the current revolution in neuroscience, focusing on the surprising neuroplasticity (malleability) of both the injured and normal brain.

Salad oil may fuel hydrogen car of future

August 26, 2004

Sunflower oil could prove to be a source for a hydrogen generator that uses only sunflower oil, air and water vapor. The secret lies in two catalysts, one based on nickel, the other on carbon.

Rescue Robot Exercise Brings Together Robots, Developers, First Responders

November 26, 2008

The National Institute of Standards and Technology held a rescue robot exercise in Texas last week, sponsored by the Department of Homeland Security, in which about three dozen robots were tested by developers and first responders in order to develop a standard suite of performance tests to help evaluate candidate mechanical rescuers.

Specially Bred Mice May Hold Keys to Personalized Medicine

June 5, 2007

Scientists at the Jackson Laboratory have developed a genetically diverse panel of mice bred to match the genetic makeup of most human genetic profiles to help predict how people with specific genotypes will respond to experimental drugs.
