Axonal Actin

How actin is organized in the axons and dendrites of neurons is largely unknown. Xu et al. (p. 452, published online 13 December 2012) imaged actin in axons and dendrites using stochastic optical reconstruction microscopy. 

"The rings were so periodic you could do a Fourier Transform!"—Prof. Xiaowei Zhuang
beautiful images, great work

he admits that the field has already been studied since the 1930s, but the arrogance still lingers

Bioglyphs - Art using bacterial bioluminescence 2002

Bioluminescence is simply light produced by a chemical reaction which originates in an organism. This project was a collaboration bewteen the the Center for Biofilm Engineering and the Montana State University School of Art. The project was created by using cultures of marine bacteria Vibrio fischeri that produces light in response to sensing certain concentration of communication molecules within its colonies. The bacteria had to be grown in conditions mimicking cold and dark sea water in order to multiply to sufficient number for light production that peaks over the course of several days and then declines as the bacteria use up all available nutrients.

not exactly fluorescent proteins but they’re still great to gawk at

Alligators Breathe Like Birds, Study Find
University of Utah scientists discovered that air flows in one direction as it loops through the lungs of alligators, just as it does in birds. The study suggests this breathing method may have helped the dinosaurs’ ancestors dominate Earth after the planet’s worst mass extinction 251 million years ago.

Flying Copepods

When threatened by fish, some copepods can jump straight out of the water and shoot over many times their own body lengths. From the fish’s point of view, its prey suddenly disappears.  Flying fish use the same tactic to escape from predators…Brad Gemmell from the University of Texas, Austin filmed flying copepods (Anomalocera ornata) both in the field and with a high-speed camera in the lab. As they escaped from approaching mullet, they kicked back with their legs, pulled their antennae back, and left the water.

I’m personally impressed that they can overcome the surface tension.

Bioluminescent firefly squid

Very cool photo, and a fitting final image for the top of the blog today.   There’s a little information about these creatures in Wikipedia, and a post about them in Atlas Obscura.Via Reddit.  I’ve tried without success to track back to the photographer for credit, but most “similar image” searches wind up in Japanese tumblrs that I can’t decipher.See also the incredible image of a shoreline in Australia glowing with bioluminescent algae.
