Eighty-year-old Fred from Whitstable shares his secret

Ever since I was a schoolboy of thirteen, whenever I’m feeling a bit down in the dumps I read William Cowper’s poem 'The Solitude of Alexander Selkirk'.

A team of British animators has produced a human heart so realistic it will transform surgical training.

Five hundred years ago Leonardo da Vinci transformed our understanding of the heart. Famous as a painter, sculptor and inventor, he also made detailed studies of the human body. One of his great discoveries was how heart valves eddy the flow of blood. Inspired by one of his drawings, a British heart surgeon pioneered a new way of repairing damaged hearts.

Now a brilliant team of British animators has taken the next leap. Using skills honed in the world of TV commercials and the entertainment industry, they have produced a human heart so realistic it will transform surgical training.

Alongside mother's ruin, what about model's ruin? 80s icon Paula Hamilton has had a long battle with the bottle.

Continuing the discussion started by Sir Jeremy Greenstock, Professor Mary Kaldor of the LSE explains her view of New and Old Wars.

I do think we’re in the midst of what might be called a paradigm shift in the nature of conflict and the nature of war.  Some of you may have seen Rupert Smith’s new book, The Utility of Force, where he talks about the shift from industrial war to what he calls war amongst the peoples.

It's said that anyone who understands what this image represents is forever changed by it.  How about you?

Have you ever wondered how big the universe really is? Looking up at the night sky rarely gives the viewer any idea of the scale of the objects that you can see with the naked eye. In 2003, the Hubble Space Telescope took the image of a millennium, an image that shows our place in the universe.  Have a look at this splendid video for a deeper perspective.
