    So reliant is the modern biomedical industry on this blood that the disappearance of horseshoe crabs would instantly cripple it. And in recent years, horseshoe crabs, particularly in Asia, have come under a number of threats: habitat loss as seawalls replace the beaches where they spawn, pollution, overfishing for use as food and bait. Horseshoe crabs bled for the biomedical use in the United States are returned to the ocean, but an estimated 50,000 also die in the process every year.

    There is another way though—a way for modern medicine to make use of modern technology rather than the blood of an ancient animal. A synthetic substitute for horseshoe-crab blood has been available for 15 years. This is a story about how scientists quietly managed to outdo millions of years of evolution, and why it has taken the rest of the world so long to catch up.

The Last Days of the Blue-Blood Harvest

Bad wreck on the bike trail this morning. A jogger waved a warning as I approached the scene of a half-dozen EMTs loading someone onto a stretcher. I chose to exercise the bystander effect and talked with the jogger some distance from the site.

He hadn't seen the incident, but said the guy "screamed pretty loud" when they moved him. It's a tricky and tight blind corner at the bottom of downslopes in two directions, where the trail turns under I-66.

Yesterday afternoon I saw a close call at another bad spot, a sharp corner at the bottom of a hill where I have previously seen the aftermath of a collision. This time, a guy passed me on the downslope with an electric assist bike. You would think e-bikers would be happy to brake since they have the motor to help them get back up to speed, but in my experience they seem very protective of their momentum. He cut the corner pretty sharp, probably crossing the center line, and his shoulder came within an inch or two of the shoulder of a pedestrian walking the other way. The walker, engrossed in a smartphone world, never knew what didn't hit him. Would have been good for the highlight reel but I had earlier stopped the camera when trying to make sure it was on.

Be safe out there.

Lately I've learned to feel less bad about not reading these "policy" books. Sure, it's arguably better to read every chapter of Capital in the Twenty-First Century than look at animated gifs, but by consuming a variety of reviews, blog arguments, and interviews I can get a pretty good idea of the contents (as well as I would remember some time after reading, anyway) and also a rounded view of how the arguments were received and criticized. Mainly, I can enjoy exposure to a lot more books, and when the content-to-length ratio seems high enough I'll read it anyway.

Caplan got a lot of traction in the circles I follow, and some from a wider audience; he wished for more in Leftist Lessons of The Case Against Education. I picked this review because it gave the most complete synopsis of the book that I have seen, and was also remarkable for the way the book anticipated the objections in the review.

The wishful thinking about where Ed dollars could be better spent seems like a weak point on both sides.

You'll never guess who did it!

On Radical Markets --Apr 20, 2018

    The roughly contemporary architecture at Jericho is devoid of artistic merit or large-scale sculpture, and Çatalhöyük, perhaps the most famous Anatolian Neolithic village, is 2,000 years later.

    At present Göbekli Tepe raises more questions for archaeology and prehistory than it answers. It remains unknown how a force large enough to construct, augment, and maintain such a substantial complex was mobilized and compensated or fed in the conditions of pre-sedentary society.

Puffin beaks are fluorescent

    Unlike humans, birds have always known about the extra colours in the puffin bill. That's because they can see a whole other dimension of hues, said Dunning.

    Humans see colours that are a mix of red, blue and green light, he notes, while birds have a fourth colour in the mix — a property called tetrachromatic vision.

Last call for players in Hubski Game III of Diplomacy. Two slots remain open and the game starts tomorrow night.

Join code: hubski

My favorite part is when mk accidentally sends private dispatches to the public channel.

The intro is a good place to start:

I figured things out as I went along during the first game. Jump in and learn!

Hubski plays Diplomacy!

Game 3 is open for anyone to join using the code "hubski", all are welcome and no experience is required.

There is space for five more players. Gameplay is easy to learn and requires a few minutes to submit orders once a day.

    But, alas, this color space has some unhelpful properties. For one, not all triplet values (also called tristimulus values) are physically possible. Consider the LMS coordinates (0, 1, 0). To physically achieve this coordinate, we would need to find some way of stimulating the M cones without stimulating the L or S cones at all. Because the M cone’s sensitivity curve significantly overlaps at least one of L or S at all wavelengths, this is impossible!

Impossible color!

mk, spencerflem, the game has been recreated on the original server:

Join code is 'hubski'.

The pace is "slow," one turn every 36 hours, plenty of time to scheme and ponder. WebDiplomacy will advance the turn when everyone is ready; we found that the other site rolls unused minutes over so turns could take quite a while when England neglected to check in.

We need seven players to have a good game; let's do some promotion in the next Pubski.
