Secret to making cheap, high-density data storage discovered

  • PDF
TechAndComputer (Oct. 10, 2012) — Imagine being able to store thousands of songs and high-resolution images on data devices no bigger than a fingernail. Researchers from A*STAR's Institute of Materials Research and Engineering (IMRE) and the National University of Singapore (NUS) have discovered that an ultra-smooth surface is the key factor for "self-assembly"

Self-assembly is a a cheap, high-volume, high-density patterning technique. It allows manufacturers to use the method on a variety of different surfaces. This discovery paves the way for the development of next generation data storage devices, with capacities of up to 10 Terabits/in2 which could lead to significantly greater storage on much smaller data...

Electronic health records shown to improve the quality of patient care

  • PDF
TechAndComputer (Oct. 9, 2012) — A new study by Weill Cornell Medical College researchers, published in the Journal of General Internal Medicine, provides compelling evidence that electronic health records (EHRs) enhance the quality of patient care in a community-based setting with multiple payers, which is representative of how medicine is generally practiced across the United States.

The use of EHRs is on the rise, in part because the federal government has invested up to $29...

TechAndComputer (Oct. 2, 2012) — A technique that uses acoustic waves to sort cells on a chip may create miniature medical analytic devices that could make Star Trek's tricorder seem a bit bulky in comparison, according to a team of researchers.

The device uses two beams of acoustic -- or sound -- waves to act as...
