Wellcome Image Awards

If you're into hi-tech photography, the current exhibition at the Wellcome Collection in London is a must. CLICK to view the 16 winning photos in the Wellcome Image Awards 2012. Above is Annie Cavanagh and David McCarthy's false-coloured scanning electron micrograph of Caffeine Crystals. Did you know that 90 per cent of adults consume caffeine daily in coffee, tea, soft drinks or energy drinks and that caffeine is a crystalline xanthine alkaloid pesticide produced by some plants to paralyse and kill certain insects feeding on them? Now you do. The show runs until 31 December.
