[00:04.75]M:Some living organisms emit their own light, a process we call bioluminescence.
[00:10.35]This phenomenon occurs in various species, including certain types of fungi, fish, and insects like fireflies. Bioluminescence is typically a result of a chemical reaction that involves the enzyme luciferase and the molecule luciferin.
[00:26.83]When these two substances interact in the presence of oxygen, light is produced. Bioluminescence serves different purposes for different species.
[00:36.07]For example, the spotted lanternfish uses its bioluminescent light for camouflage in the dark ocean.
[00:43.01]This process, known as counter-illumination, involves the fish matching the light coming from above, making it less visible to predators below and thus less vulnerable to attack.
[00:54.61]Fireflies, on the other hand, use bioluminescence for mating signals.
[00:59.37]Scientists are intrigued by bioluminescence not only because of its beauty but also for its potential applications in medicine and technology.
[01:08.14]For instance, bioluminescent markers are used in biological research to track cellular processes.
[01:14.70]Moreover, there is ongoing exploration into how bioluminescent properties can be harnessed for developing sustainable lighting solutions.
[01:23.02]We’ll talk about some specific applications for lighting next time.
