Ice Warrior: The Polar Bear’s Light Scattering Technology

Polar Bears at the Wilhelm Zoo, Stuttgart/Germany.

I was thrilled to be invited writing about the ice theme, specifically about the polar bears. I have always considered polar bears the epitome of ice warriors (been always fascinated by Pullman’s His Dark Materials’ novels). Millions of years of evolution equipped the polar bear to survive the extremely low winter temperatures  in the arctic...

The unbelievable fact that frogs can survive the freezing of their own body led me to writing this article in the theme session of ice. Frogs are cold-blooded organisms and their body temperature conforms with their immediate surrounding. This feature would normally prevent habitations of cold climate due to the risk of lethal freezing. Nevertheless,...

Light production via bioluminescence

bioluminescence

The creation of light is for sure one of the most interesting natural phenomena, especially if it occurs by living organisms. Bioluminescence means the emission of light by an organism as a result of a natural chemical reaction [1]. A remarkable variety of marine animals, underground organisms and terrestrial animals are able to produce light by...

Light Harvesting in Nature

2013-12-01-14-44-00

Greetings Readers, For the theme of light, I am going to discuss how nature harvests light. We have discussed in one of our previous articles, how polar bears use light reflection and scattering (similar to fiber optics) for light absorption, but sophisticated light harvesting strategies this mechanism is not only limited to animals. Light Harvesting in Polar...
