Very innovative approach to hyper-parallel computation. Not immediately practical, but then neither yet is quantum computing. The era of encryption based on computational complexity is beginning to end. Via Ky Waegel, Michael Zyda and Dr(!) Sherol Chen.

Unique capture of wind energy via piezoelectric material on tree-shaped structures. “...What the Ohio State group, led by mechanical and aerospace engineering professor Ryan Harne, found is that it may be possible after all to convert relatively random range of vibration frequencies to useful energy by exploiting the natural resonant frequency of tree-like structures...” — Via Bojana Vuksanovic.

The geopolitics of honey production. In the so-called developed world, pesticide use has risen and honey production has fallen. By economic necessity, Cuba has used purely organic farming technology. Now they have a robust and healthy bee population, and increasing honey exports. Via SallyAnne Syberg on facebook.

The complex cash-free market in human kidneys. By the 1990s, kidney transplants had become a safe and effective medical treatment. However finding tissue-compatible donors at the right time is difficult. In 2000 there were 2 transplants in the US. Today there are 600 a year. The fascinating economic and algorithmic system that enables this—largely the work of Stanford professor +Al Roth—was explored in Saturday's (rebroadcast) episode of Freakonomics Radio. Amazing story!

Love this breezy video introduction by Dr. Katie Steckles to the fold-and-cut theorem and the joy of mathematics, particularly geometry. She includes a construction for all the letterforms from “A to Zed”. The papers to which she refers: Folding and Cutting Paper (1998 http://erikdemaine.org/papers/JCDCG98/paper.pdf) and Folding and One Straight Cut Suffice (1999 http://www.ime.usp.br/~fa…/origami/fold_one_straight_cut.pdf).

Beautiful bird-cam footage. Around 1986 when I was first writing the boids model, I tried to imagine myself as bird in a flock. I had no idea videos like this would someday exist. Via Vik Sohal. Video here: https://www.facebook.com/breedofspeed/videos/415510641993095/

Stigmergy: animal experiments and simulation modeling combined to better understand collective construction in social insects. Sorry to my “normal” friends, some of my geeky colleagues will appreciate this: Stigmergic construction and topochemical information shape ant nest architecture by Anaïs Khuong, Jacques Gautrais, Andrea Perna, Chaker Sbaï, Maud Combe, Pascale Kuntz, Christian Jost and +Guy THERAULAZ. Open access paper: http://www.pnas.org/.../early/2016/01/13/1509829113.full.pdf
