Guardian: One of science’s longest-running imaging competitions, the Nikon Small World awards, has announced the 2010 winners. Celebrating its 35th anniversary, the competition received entries from scientists in 63 countries. This year’s first prize went to Jonas King, of the biological sciences department of Vanderbilt University in Nashville, Tennessee. He used fluorescence microscopy to capture his close-up view of the heart of a mosquito (see image below). To see all the winning images, visit the Nikon Small World online gallery.
