A new search engine could help scientists and researchers squeeze more useful
information out of the Web, say its developers. Rather than returning lists of
possible website hits, the Visualization Information Tool (www.visit.uiuc.edu)

towards the centre. Arrows show hyperlinks between them, making it possible to
see which pages other people consider authoritative or useful. 鈥淧eople can
interpret it much better,鈥� says Jim Levin, one of the developers at the
University of Illinois at Urbana-Champaign.
