A new liquid crystal laser that can dial-up any wavelength of light you need, a laser-powered projector technology that turns any surface into a touch-screen, and a laser that fires salvoes of X-rays to make light work of unlocking the molecular fabric of matter are the focus of this week's laser-led show. We also meet HECToR, one of the world's fastest computers that just got a tenfold power boost, and David Braben unveils the credit-card sized Raspberry Pi, the world's smallest home micro he's helped to invent...

In England there are 450,000 kilometres of managed hedgerows, often containing hawthorn and often dubbed “corridors for wildlife” – be it beetles, bird, butterflies or even dormice. Most farmers trim their hedges every year. But now new research has shown that less frequent tri...
