to emit light has a name bioluminescence. it occurs when a protein called the lucifer in and an enzyme called the lucifer range react with energy rich a.t.p. molecules and oxygen. as the report mentioned this chemical process is a very efficient. ninety five percent of the energy it produces is emitted as light just five percent as heat. within can doesn t light bulbs that ratio is reversed. in efficiency inspired researchers to make l.e.d.s. modeled on firefly it s. for more stories from the world of research on technology that for our website d.w. dot com slash science and get in touch with us on twitter and facebook we d love hearing from you. good high tech paving stones soon be cleaning the
