China's struggle to measure economy clouds outlook

April 16, 2013 9:32 pm | by Joe McDonald, AP Business Writer | News | Comments

After China reported quarterly economic growth of 7.7% this week, global markets reacted by falling, wiping out billions of dollars in stock. The reason? Growth came in under the 8% expected by forecasters. The plunge highlighted complaints about the possible inaccuracy of Beijing's official data and the intense, possibly excessive importance traders attach to a handful of Chinese economic indicators.

New imaging device is flexible, flat, and transparent

February 20, 2013 12:20 pm | News | Comments

A research team in Austria has developed an entirely new way of capturing images based on a flat, flexible, transparent, and potentially disposable polymer sheet. The new imager, which resembles a flexible plastic film, uses fluorescent particles to capture incoming light and channel a portion of it to an array of sensors framing the sheet. With no electronics or internal components, the imager’s elegant design makes it ideal for a new breed of imaging technologies.

Self-assembled biological filaments form 3D microelectronics

February 12, 2013 1:24 pm | News | Comments

The size of electronic components is reaching a physical limit. While 3D assembly can reduce bulk, the challenge is in manufacturing these complex electrical connections. Biologists and physicists in France have recently developed a system of self-assembled connections using actin filaments for 3D microelectronic structures. Once the actin filaments become conductors, they join the various components of a system together.
