We hear about the project to build the world's biggest optical telescope. There's some fascinating research which will help us understand how we speak. Also there's news of an innovative use of Google Earth, and we ask "is the CD player dead?"

Reflecting on the stars

Adam Walton chats to astronomer Richard Ellis, originally from Colwyn Bay, sho is one of the leading lights behind the project to build the "30 metre" telescope, which will have a mirror three times the diameter of the current largest optical telescope. It will enable astronomers to see more details of the formation of stars and galaxies than ever before.

See... Think... Speak

Guillaume Thierry of Bangor University joins us to discuss the research that he has been carrying out in conjunction with scientists in Barcelona, which, for the first time has been able to measure the time it takes for our brains to retireve the words we need for speech. It's hoped his work will lead to a much more detailed understanding of the way human speech is produced.

Demise of the "shiny beermat"

Linn Products, the British based company known for their high quality audio equipment have become the first company to announce their intention to stop making CD players. According to Gilad Tiefenbrun of Linn, the future for audio lies in high quality "streaming" of music.

Climate change education

Innovative use of Google Earth in an educational environment is discussed by Simon Haslett who is Director of the Centre of Excellence in Learning and Teaching at the University of Wales, Newport. He outlines the "Sands of Time" project which explores how Google Earth can be used by students as part of their studies into climate change.
