Microsoft Word / EndNote slow downs

If you experience serious slow downs/lags while using Word with Endnote, try the following two steps:
  1. In Word 2002 (XP)/2003, select Tools / EndNote / Cite While You Write Preferences.
    In Word 2007, go to the "Add-ins" tab and EndNote / Cite While You Write Preferences.

  2. Uncheck the two boxes labeled "Scan for temporary citations" and "Check for citation changes".
Note that this does not disable Instant Formatting or Cite While You Write. It simply alters the way Instant Formatting works so that the functions that trigger the lag issue are not invoked

A peak in to the Memory with fMRI

Functional magnetic resonance imaging (fMRI) looks more and more like a window into the mind. In a study published online today in Nature, researchers at Vanderbilt University report that from fMRI data alone, they could distinguish which of two images subjects were holding in their memory--even several seconds after the images were removed. The study also pinpointed, for the first time, where in the brain visual working memory is maintained.

More chip cores can mean slower supercomputing

The worldwide attempt to increase the speed of supercomputers merely by increasing the number of processor cores on individual chips unexpectedly worsens performance for many complex applications, Sandia simulations have found.

A Sandia team simulated key algorithms for deriving knowledge from large data sets. The simulations show a significant increase in speed going from two to four multicores, but an insignificant increase from four to eight multicores. Exceeding eight multicores causes a decrease in speed. Sixteen multicores perform barely as well as two, and after that, a steep decline is registered as more cores are added.

Study Finds Color Boosts Brain Performance

According to a new study, the brain performance of people is unconsciously enhanced by different colors depending upon the nature of the task. In their study, University of British Columbia researchers set out to resolve a long running debate among advertisers about which color, red or blue, stimulates the brain more.

Marketing professor Juliet Zhu says both colors stimulate the brain, but it depends upon the nature of the activity. "If the task is calling for attention to details, then red color will help in particular. But if the task is more creative in nature, then (a) blue color will help," she said. Zhu and colleagues followed 600 participants between 2007 and 2008, tracking their performance on six cognitive tests on a computer that required either detail orientation or creativity.

While exposed to tasks on a red screen, Zhu says the volunteers in one group were asked to memorize a list of words and then recall them twenty minutes later. "What we found was that those in the red color background condition were able to make more accurate recalls than those in the blue background conditions," he said. Zhu says the color red enhanced the detail-oriented skills of the volunteers by 31 percent.She says people using blue computer screens to perform creative works scored two times higher on a scale measuring creativity than people who performed the activities on red screens.

The study on color and brain performance is published this week in the journal Science "Blue or Red? Exploring the Effect of Color on Cognitive Task Performances"
