Free Apps Drain Smartphone Energy on 'Advertising Modules'

April 4, 2012 11:56 am | Comments

Researchers have shown that popular free smartphone apps spend up to 75 percent of their energy tracking the user's geographical location, sending information about the user to advertisers and downloading ads. "It turns out the free apps aren't really free because they contain the hidden cost of reduced battery life," said Y.

Listening to the Radio Even with an Electric Drive

April 4, 2012 9:18 am | Comments

To enable radio reception in electric vehicles, manufacturers must install filters and insulate cables, since electrical signals will otherwise interfere with music and speech transmissions. Now, using new calculation methods, researchers are paving the way for pure listening pleasure while also helping to lower the associated costs.

Nanoscale magnetic media diagnostics by rippling spin waves

April 4, 2012 4:43 am | Comments

Memory devices based on magnetism are one of the core technologies of the computing industry, and engineers are working to develop new forms of magnetic memory that are faster, smaller, and more energy efficient than today's flash and SDRAM memory. They now have a new tool developed by a team from the National Institute of Standards and Technology (NIST), the University of Maryland Nanocenter and the Royal Institute of Technology in Sweden—a method to detect defects in magnetic structures as small as a tenth of a micrometer even if the region in question is buried inside a multilayer electronic device.

Researchers Develop Graphene Supercapacitor Holding Promise for Portable Electronics

April 3, 2012 1:08 pm | Comments

Electrochemical capacitors (ECs), also known as supercapacitors or ultracapacitors, differ from regular capacitors that you would find in your TV or computer in that they store substantially higher amounts of charges. They have garnered attention as energy storage devices as they charge and discharge faster than batteries, yet they are still limited by low energy densities, only a fraction of the energy density of batteries.

Transparent Memory Chips Are Coming

April 3, 2012 1:04 pm | Comments

Want a see-through cellphone you can wrap around your wrist? Such a thing may be possible before long, according to Rice University chemist James Tour, whose lab has developed transparent, flexible memories using silicon oxide as the active component. Tour revealed today in a talk at the national meeting and exposition of the American Chemical Society in San Diego that the new type of memory could combine with the likes of transparent electrodes developed at Rice for flexible touchscreens and transparent integrated circuits and batteries developed at other labs in recent years.
