Why People Quit and Come Back to Facebook

Why People Quit and Come Back to Facebook

With more than a billion active accounts worldwide, it can be easy to forget that some people don’t use Facebook.   A study by Cornell University researchers to be presented this week in Paris suggests that “non-use” of the social networking site is fairly common — a third of Facebook users take breaks from the […]

Battery Low? Give Your Mobile Some Water

Battery Low? Give Your Mobile Some Water

A power source for your mobile phone can now be as close as the nearest tap, stream, or even a puddle, with the world’s first water-activated charging device.   Based on micro fuel cell technology developed at KTH Royal Institute of Technology in Stockholm, the MyFC PowerTrekk uses ordinary water to extend battery life for […]

Plastic Film Is the Future of 3-D On-The-Go

Plastic Film Is the Future of 3-D On-The-Go

Mobile device users will soon be able to view brilliant 3D content with the naked eye with a nano-engineered screen protector that turns ordinary mobile screens into 3D displays. The unique plastic film can also potentially be used as next generation security tokens employed by banks and corporations.   Temasek Polytechnic (TP) and A*STAR’s Institute […]

Biological Transistor Enables Computing Within Living Cells

Biological Transistor Enables Computing Within Living Cells

When Charles Babbage prototyped the first computing machine in the 19th century, he imagined using mechanical gears and latches to control information. ENIAC, the first modern computer developed in the 1940s, used vacuum tubes and electricity. Today, computers use transistors made from highly engineered semiconducting materials to carry out their logical operations.   And now […]

How Hard Is It to ‘De-Anonymize’ Cellphone Data?

How Hard Is It to ‘De-Anonymize’ Cellphone Data?

The proliferation of sensor-studded cellphones could lead to a wealth of data with socially useful applications — in urban planning, epidemiology, operations research and emergency preparedness, among other things. Of course, before being released to researchers, the data would have to be stripped of identifying information. But how hard could it be to protect the […]

Information Technology: Improving the Health of Machines

A novel adaptive management system boosts the efficiency of wireless sensor networks that monitor surrounding environments. Electronic engineers in Singapore have developed and successfully tested a management system that increases the efficiency of wireless sensor networks for monitoring machine health. The new system, known as an adaptive classification system (ACS), reduces the power consumption of […]

Ultra-High-Speed Optical Link Sets New Power Efficiency Record

Ultra-High-Speed Optical Link Sets New Power Efficiency Record

Ultrafast supercomputers that operate at speeds 100 times faster than current systems are now one step closer to reality. A team of IBM researchers working on a U.S. Defense Advanced Research Projects Agency (DARPA)-funded program have found a way to transmit massive amounts of data with unprecedentedly low power consumption.   The team will describe […]

Creating Indestructible Self-Healing Circuits

Creating Indestructible Self-Healing Circuits

Imagine that the chips in your smart phone or computer could repair and defend themselves on the fly, recovering in microseconds from problems ranging from less-than-ideal battery power to total transistor failure. It might sound like the stuff of science fiction, but a team of engineers at the California Institute of Technology (Caltech), for the […]

Engineers Develop Techniques to Boost Efficiency of Cloud Computing Infrastructure

Computer scientists at the University of California, San Diego, and Google have developed a novel approach that allows the massive infrastructure powering cloud computing as much as 15 to 20 percent more efficiently. This novel model has already been applied at Google. Researchers presented their findings at the IEEE International Symposium on High Performance Computer […]
