Tornadoes can occur whenever and wherever conditions are right. The strongest, longest-lived tornadoes (long-track EF5) are the least common, but produce the most devastating damage. Yet there's a lack of published research on these tornadoes embedded within parent storms.

Read about a first-of-its-kind simulation — made possible by Blue Waters at the National Center for Supercomputing Applications (NCSA) at the University of Illinois, US — detailing the genesis, maintenance, and decay of a long-track EF5 tornado.


Last week, over 1,600 delegates from across the globe gathered in Geneva, Switzerland, for 'the World Summit on the Information Society (WSIS) +10 High-Level Event'. A major report published at the event indicates that significant progress has been made over the last decade in increasing mobile cellular coverage, with all rural communities in the world likely to be covered by 2G mobile cellular signals by 2015. However, internet connectivity remains a challenge and access to broadband continues to be unequal.
