Transcript of Bioluminescence: OTB

Bioluminescence
What is Bioluminescence?
Bioluminescence is light produced by a chemical reaction within a living organism.
It's a form of chemiluminescence, which is simply a chemical reaction in which light is produced
Bioluminescence is a "cold light, " meaning that less than 20% of the light generates heat
Most bioluminescent organisms are marine, although terrestrial species such as fireflies and types of worms use bioluminescence as well
Bioluminescence is caused by a chemical reaction between luciferin and either luciferase or photoprotein
Article 1:Researchers shine light on origin of bioluminescence
This article focused on a new re-discovery of a Californian millipede that has not been seen since 1967
It explained how research on this particular millipede led to discoveries in bioluminescence evolution, as a new connection between the level of toxicity and the level of brightness was established
Millipedes with larger cyanide glands, characteristically those living in higher altitude with more predators, glowed brighter
Article 3: 6 Bright Ideas for Bioluminescence Tech
This article is truly more of a list of possible uses for bioluminescence technology
It details the possibilities of how we might use bioluminescence tech in the future
Ideas include glowing candy, replacing streetlights with bioluminescent trees, plants that glow based on their needs, bacteria that glows to detect water quality, illuminate biological processes, and for possible military use
Article 2: Scientists to Use Firefly Bioluminescence to Create Energy-Free Lighting
This article details a recent trial in which a team of researchers used the process of bioluminescence resonance to harnes firefly power into energy
They were able to duplicate the chemical reaction that happens inside a firefly and harness it in the form of glowing nanorods
The nanorods are composed of an outer shell of cadmium sulfide and an inner core of cadmium seleneide
By manipulating the size of the core, and the length of the rod, the team was able to alter the color of the produced light
With more research, the power of these glowing nanorods can be manipulated to power LED lights and act as other light sources

Discussion Questions
1. What possibilities can you see for biolume tech? How useful would they be?

2. How would the implementation of biolume tech focusing on energy impact our society?

3. Is biolume tech worth investing in? Why or why not?

The How and Why Behind Bioluminescence
Pros and Cons of Biolume Tech
Appeals of Biolume Tech
Ethos
: Many prominent scientists as well as prestigious research facilities have programs surrounding biolume tech, the U.S. military has donated millions to research
Pathos
: How awesome would it be to have glowing trees? And free energy is cool and save the whales
Logos
: Numerous possibilities rest with biolume tech, financial prospects
New exciting tech with many possibilities
Many clean energy opportunities
Light up sneakers would never be the same
Not incredibly explored yet
Possible relation to toxicity due to chemical reaction
Money to invest is difficult to find
Pros
Cons
Created by chemical reaction between photoproteins and substrate
Used as defense mechanism, usually to warn predators that the organism is poisonous
Many organisms activate their luminescence when threatened
Now onto the how...
