Jan. 22, 2013 In 2009, the Securities and Exchange Commission mandated that public companies submit portions of annual (10-K) and quarterly (10-Q) reports -- in a digitized format known as eXtensible Business Reporting Language (XBRL). The goal of this type of data was to provide more relevant, timely, and reliable "interactive" data to investors and analysts. The XBRL-formatted data is meant to allow users to manipulate and organize the financial information according to their own purposes faster, cheaper, and more easily than current alternatives.
But how useful and usable is the new data to analysts and investors? The authors, early proponents of interactive data, from Columbia Business School's Center for Excellence...

Jan. 7, 2013 Despite wide investments nationally in electronic medical records and related tools, the cost-saving promise of health information technology has not been reached because the systems deployed are neither interconnected nor easy to use, according to a new RAND Corporation analysis.
The potential of health information technology to both improve patient care and reduce spending are unlikely to be realized until health care providers reengineer their processes to...

Jan. 3, 2013 Urban agriculture is promoted as a strategy for dealing with food insecurity, stimulating economic development, and combating diet-related health problems in cities. However, up to now, no one has known how much gardening is taking place in urban areas. Researchers at the University of Illinois have developed a methodology that they used to quantify the urban agriculture in Chicago.

Dec. 20, 2012 Information within the bonds of molecules known as super benzene oligomers pave the way for new types of quantum computers.
Scanning tunneling microscopy (STM) is routinely employed by physicists and chemists to capture atomic-scale images of molecules on surfaces. Now, an international team led by Christian Joachim and co-workers from the A*STAR Institute of Materials Research and Engineering has taken STM a step further: using it to identify the quantum states...
