Bursts of Nature

Nature makes its own gorgeous, tiny fireworks. Who knew that deep in the darkness of your cup of black coffee, caffeine crystals helping you wake up look like this? The image, one of the winners of the 12th-annual Wellcome Collection image awards, shows a false-coloured scanning electron micrograph of large caffeine crystals. Each year, the Collection honors the best scientific photography with the awards, allowing us to see amazing imagery, from beautiful bacteria to human tissue.
