There are just three weeks to go before the closing date for entries in the £50,000 MacRobert Award 2005 The competition, organised by the Royal Academy of Engineering, seeks to recognise groups (of up to five people) or individuals who have "exploited a major engineering breakthrough".

Last year, the £50k prize was scooped by IBM's team responsible for the company's WebSphere software. They saw off competition from Pilkinson's self-cleaning windows, 3D displays from Sharp, and a new kind of diesel injection system to win the day. More information on the runners up can be found here (http://www.raeng.org.uk/prizes/macrobert/finalists/).

If you think your team has what it takes to make the shortlist, you can download an entry form here (http://www.raeng.org.uk/prizes/macrobert/). Entries must reach the Royal Society before 31 January. ®
