For over a century, the accepted value for a firefly\u2019s brightness has mostly stood, tracing its origins to experiments carried out in 1912. Through rigorous new analysis published in the American Journal of Physics<\/i><\/a>, David Silver of Remiza AI in New York has discovered that this value has likely been vastly overestimated. His results provide a stark reminder of what can happen when widely accepted older measurements are converted into modern standard units.<\/p>\n

Out of the hundreds of species of animals, fungi and bacteria that produce their own light, fireflies are the most widely studied. In the 1880s, experiments revealed that their flashing bioluminescence emerges from a catalyzed reaction between an organic compound named luciferin and an enzyme named luciferase.<\/p>\n

In 1912, the brightness of these flashes was measured for the first time by William Coblentz\u2014one of the founders of modern radiometry. \u201cCoblentz reported that the flash of the firefly Photinus pyralis ranged from 1\/50th to 1\/400th the power of a candle, with 1\/400 predominating,\u201d Silver describes.<\/p>\n","protected":false},"excerpt":{"rendered":"
