Fireflies light up to attract mates while some species of algae glow when the surrounding water is disturbed. The uses of bioluminescence in the natural world are just as wide-ranging. It is present in 76% of deep-sea creatures and has independently evolved dozens of times, including at least 27 occasions in marine fish alone. Organisms as diverse as fireflies, fungi and fish have the ability to glow through bioluminescence. This phenomenon – where chemical reactions inside an organism's body produce light – can be observed in many places in nature. These ethereal experiments are also underway across France, including at the capital's Roissy-Charles-de-Gaulle airport.īut unlike standard streetlamps, which often emit a harsh glare and need to be hooked up to the electricity grid, these otherworldly lights are powered by living organisms through a process known as bioluminescence.
Soon, the same azure glow will illuminate the nearby, tree-lined Place André Thomé et Jacqueline Thomé-Patenôtre, located just across from the aptly named La Lanterne performance hall, at night. Members of the public who received a vaccine last year were invited to bathe in the glow for a few minutes while they waited in the recovery area. In a tranquil side room of the Covid-19 vaccination centre in Rambouillet, a small French town around 30 miles (50km) south-west of Paris, a soft blue light emanated from a row of cylindrical tubes.
