Extending Battery Life for Mobile Devices

University of Illinois engineers have developed a form of ultra-low-power digital memory that is faster and uses 100 times less energy than similar available memory. The technology could give future portable devices much longer battery life between charges.

If artificial intelligence outsmarts two live contestants, is that a bad sign for the humans?

This week's question addresses a robot and one of America's most well-known game shows. A supercomputer named Watson, designed by IBM and consisting of 90 IBM Power 750 Express servers, is set to face two human contestants on the US quiz show Jeopardy this week. IBM says Watson signals a new era in computing where machines will increasingly be able to learn and understand humans' more subtle requests. Jeopardy is seen as the greatest challenge for Watson because of the show's fast format and the clues' frequent emphasis on puns, riddles, and creativity in the language: something humans have traditionally excelled at understanding and computers have not. What do you think? If artificial intelligence outsmarts two live contestants, is that a bad sign for the humans?

Aluminum to Replace Copper as Conductor in On-board Power Systems

Electric power and electronics play an increasing role in vehicles. Currently copper is the conductive material of choice but in comparison to aluminum, it is heavy and expensive. Before aluminum can replace copper in power supply systems, a number of technological challenges need to be surmounted.

Is there another "Earth" out there, fit for life as we know it?

This week's question looks at an announcement from scientists operating NASA's Kepler satellite, who reported this week that they had identified 1,235 possible planets orbiting other stars, potentially three times the previously recorded number. Although no Earth-like planet has been determined yet, fifty-four of the possible exoplanets are in habitable zones of stars where temperatures should be moderate enough for liquid water. What do you think? Is there another "Earth" out there, fit for life as we know it? Yes or no?

Technique Boosts High-Power Potential For Gallium Nitride Electronics

Gallium nitride (GaN) material holds promise for emerging high-power devices that are more energy efficient than existing technologies – but these GaN devices traditionally break down when exposed to high voltages. Now researchers at North Carolina State University have solved the problem, introducing a buffer that allows the GaN devices to handle 10 times greater power.

Flexible Ceramic Thin Film Nanogenerator

Korea Advanced Institute of Science and Technology (KAIST), Daejeon, South Korea
Georgia Institute of Technology, Atlanta, Georgia

Keon Jae Lee, a professor in KAIST's Department of Materials Science and Engineering, and Zhong Lin Wang, a professor in the same department at Georgia Institute of Technology, have developed new forms of highly efficient, flexible nanogenerator technology using freely bendable piezoelectric ceramic thin film nano-materials that can convert tiny movements of the human body (such as heart beats and blood flow) into electrical energy.

Do social networks make us less social?

This week's Question of the Week focuses on Web 2.0 interaction. A recent report from the University of Texas, Austin, says that networking sites like Facebook make users more sociable and "afford opportunities for new expressions of friendship, intimacy and community." A recent book by Sherry Turkle, "Alone Together: Why We Expect More From Technology and Less From Each Other," conversely, makes the case that social media interactions isolate, and even dehumanize, its members.

What do you think? Do social networks make us less social? Yes or no?
