In the dark of the ocean, some animals have evolved to use bioluminescence as a defense. In the animation above, an ostracod, one of the tiny crustaceans seen flitting near the top of the tank, has just been swallowed by a cardinal fish. When threatened, the ostracod ejects two chemicals, luciferin and luciferase, which, when combined, emit light. Because the glow would draw undesirable attention to the cardinal fish, it spits out the ostracod and the glowing liquid and flees. Check out the full video clip over at BBC News. Other crustaceans, including several species of shrimp, also spit out bioluminescent fluids defensively. (Image credit: BBC, source video; via @amyleerobinson)

Ka-Pow: Watch These Fish Cannons Shoot Salmon Safely Over Dams

Salmon have serious swimming skills—some travel thousands of miles to return to their original homes to breed. But even though they can jump as high as 12 feet in the air, they can’t manage to get over massive concrete dams that we have built to block their journeys back to their homes. Now one new idea could give them a boost. The plan involves whisking the fish through a long vacuum tube at speeds up to 22 miles per hour and then shooting them out the other end like a cannon.

This is hilarious reasoning, coming from a libertarian:

But when sex­ual norms are too per­mis­sive, it cre­ates mat­ing mar­ket collec­tive action prob­lems and harms the peo­ple who are most ill-equipped to han­dle sex­ual anomie.
Pamela J. Stubbart

I wonder what happens when economic regulation is too permissive?

Looking at our photos from Catalina Island, I realized that we’ve seen Chromis species in three seas.

  • Blacksmiths (Chromis punctipinnis) in the Pacific off California,
  • Brown Chromis (Chromis multilineata) in the Caribbean off Bonaire, and
  • Chromis chromis in the Aegean off Milos.

"The bottom line point is that Looking for Rights is an important work by a talented young scholar that will both change how we talk about American constitutionalism and offer numerous fruitful paths for more creative thinking about the entire American constitutional experience."

Wired: A Cloudless Atlas — How MapBox Aims to Make the World’s ‘Most Beautiful Map’, by Tim Maly

digitalurbanisms:

I really love Tim Maly’s account of Mapbox’s process. It shows us the power of combining computation power with human creativity in the production of perception. Even maps, are socially and mathematically constructed. Here’s a large chunk from his article, which should be read in its…

I first saw these cosmic Converse a couple months ago, but I didn’t think I needed to buy them right away. I’ve had so many pairs, and they wear out so quickly.

I found myself at a mall a couple weeks ago so I thought I’d see them in person, but they were out of stock. Worried that they might be a temporary style, I ordered them online, and they arrived just yesterday.

FELLOW ASTRONISTAS, MY LIFE HAS BEEN CHANGED BY A PAIR OF SNEAKERS! Not only are they silky and slightly shiny, as opposed to the typical canvas chucks, the print is a real NASA image of the Small Magellanic Cloud! Specifically the region around NGC 602 and data from Hubble, Spitzer, and Chandra space telescopes. The young stars! The dusty filaments! The background galaxy! Everything is there, on my sneakers! I’m going to stock up on extra pairs.

Oh, and neildegrassetieson approves. Too bad they don’t come in his size! (I really buried the lede there, didn’t I?)
