TechAndComputer (Apr. 4, 2011) — Economists at the Technical University of Munich (Technische Universitaet Muenchen, TUM) have developed a website that predicts individual stock trends. To this end, economists are using automatic text analysis methods to evaluate thousands of daily Twitter microblog messages, so-called "tweets." On www.TweetTrader.net,current forecasts are available for all S&P 500 listed stocks.

TechAndComputer (Mar. 3, 2011) — An online calculator that predicts, within seconds, the presence of the three major food allergies in children has been developed by researchers at University College Cork. They have devised a new 'Cork-Southampton calculator' that gives 96% accuracy compared to current methods that are 61% -81% accurate. The research will be published online March 3 in the journal, Journal of Allergy & Clinical Immunology.
