Mr Gage was at the launch of this year's International Science Festival in Edinburgh which runs from April 5 to 20.
One of the highlights of the festival is a look at the world of bioluminescence in a new outdoor exhibition, Living Lights, held at The Mound.
The photography exhibition has moved from St Andrew Square, and will later transfer to Our Dynamic Earth for an extended run until October.
The exhibition features 60 amazing images, from organisations including Nasa, the Ocean Research and Conservation Association, National Geographic and Harvard University. The pictures reveal how the emission of light by living organisms is used. This includes fireflies who use flashes to attract mates; marine plankton that make the sea sparkle at night; anglerfish (pictured) whose bioluminescent lures attract prey and squid that expel luminescent clouds to repel predators.
