The Turner prize never fails to cause controversy, and the competition this year is no exception.

The artists Langlands & Bell have had to withdraw part of The House of Osama Bin Laden, their interactive video-based work, owing to legal complications; to find out more, tune in to the Tate’s live webcast with them on Wednesday at 6.30pm (www.tate.org.uk/onlineevents). The other nominees, Kutlug Ataman, Yinka Shonibare and Jeremy Deller, have already given talks; these can be viewed in the online archive.

Detractors of the award include the Stuckists, a movement of contem- porary painters who pillory its conceptualist bias. Delve into their work, artistic ethos and alternative exhibition — the Real Turner Prize — at www.stuckism.com.

The Royal Society, which has promoted scientific inquiry since 1660, was thrust into the 21st century last week with the launch of its redesigned site (www.royalsociety.co.uk). This is a perfect resource for teachers and politicians, with science-related news and historical archives accompanied by features and web-streamed debates on hot issues such as stem-cell research and nanotechnology.

For a clear perspective on the heavens, visit www.chandra.harvard.edu. The sight of two black holes colliding is one of the many spectacular images captured by the orbiting Chandra x-ray observatory, on show at this vast database.

Finally, the disciplines of art and technology come together strikingly at www.panoramas.dk, which hosts “immersive panoramic images”. These pin-sharp 360-degree views cover subjects as diverse as the lunar landings, the Burning Man festival and Niagara Falls.
