Scientists at the University of Cambridge have perfected a way of extracting titanium that could reduce costs by 75 per cent, says a report in New Scientist. Discovered accidentally, the method has been tested by the Defence Evaluation and Research Agency, with good results. The scientists have set up a company, British Titanium, to exploit the new method.

They believe that an abundance of titanium, lighter and tougher than steel, could help architects construct ever taller buildings and longer bridges.
