This is dedicated to everyone who is living through a really cold winter in North America.

You just get done breaking the ice, and you look up and … whaaa?

Hey, if it isn’t warm, it’s at least bright.

Oh well, here the northern lights in Norway too:

Find extra blankets.

johnp @ 3, Thank you for the link to the original document. By the way, do you know of anyone out there who could explain how in the world those efficient mechanisms “appeared” ? The full study does not seem to answer that question. Simply mind-boggling, isn't it?Dionisio

Here is a glimpse at how the aurora borealis is formed by solar flares interacting with the magnetic field:
NASA Magnetic Reconnection - video http://www.youtube.com/watch?v=7_Gny2JVqQ8 The science behind northern lights - October 2, 2012 Excerpt: ,,,(solar) flares release a burst of charged particles, or plasma, into the solar system. When they come our way, they whack into the Earth's magnetosphere, which is made up of its own stream of charged particles. That collision causes particles to break free of the magnetosphere and cascade toward the Earth's magnetic field lines, usually traveling toward the poles. "The aurorae happen when these high-energy particles bap into atoms and molecules in the Earth's atmosphere, typically oxygen," Nemiroff said. Light is emitted as part of the reaction. Those particles can also wreak havoc. "The plasma cloud can cause the Earth's magnetic field to fluctuate," Nemiroff said. "At worst, that can knock out satellites and even power grids.",,, http://phys.org/news/2012-10-science-northern.html Cluster Spacecraft Detects Elusive Space Wind - July 2, 2013 Excerpt: A new study provides the first conclusive proof of the existence of a space wind first proposed theoretically over 20 years ago. ,,plasmasphere, a donut-shaped region extending above Earth's atmosphere.,, "After long scrutiny of the data, there it was, a slow but steady wind, releasing about 1 kg of plasma every second into the outer magnetosphere: this corresponds to almost 90 tonnes every day.,,, "The plasmaspheric wind is an important element in the mass budget of the plasmasphere,,, The plasmasphere, the most important plasma reservoir inside the magnetosphere, plays a crucial role in governing the dynamics of Earth's radiation belts. http://www.sciencedaily.com/releases/2013/07/130702100106.htm Image of Belts http://www.eos.unh.edu/Spheres_0812/graphics/summer12_pics/magneto_lg.jpg The Earth as You've Never Seen it Before: Atmosphere, Airglow and Aurora - video https://vimeo.com/42909676 Spectacular Norway Northern Lights - video http://www.youtube.com/watch?v=izYiDDt6d8s Dance of The Sprits, Full HD, real-time Aurora Footage http://www.youtube.com/watch?v=Ezobpz55EEY

Dionisio- great article, thanks. The full study can be downloaded as a pdf at http://dabiri.caltech.edu/publications/Lu_etal_NComm14.pdf Love me some google scholar! :-)johnp

Bending rules for animal propulsion Animal propulsors such as wings and fins bend during motion and these bending patterns are believed to contribute to the high efficiency of animal movements compared with those of man-made designs. However, efforts to implement flexible designs have been met with contradictory performance results. Consequently, there is no clear understanding of the role played by propulsor flexibility or, more fundamentally, how flexible propulsors should be designed for optimal performance. Here we demonstrate that during steady-state motion by a wide range of animals, from fruit flies to humpback whales, operating in either air or water, natural propulsors bend in similar ways within a highly predictable range of characteristic motions. By providing empirical design criteria derived from natural propulsors that have convergently arrived at a limited design space, these results provide a new framework from which to understand and design flexible propulsors.

Only materialistic explanations accepted. No philosophical or theistic terminology is allowed. Just answer the question using purely scientific concepts. I look forward to read some reasonably logic explanations.Dionisio
