In 2009, I published The Tangled Bank: An Introduction. I intended it as a textbook for non-majors, as well as a guide to evolution for people looking for a thorough but non-technical account of how life has gotten to be the way it is. The project proved to be far more work than I had reckoned, but I was happy with how it turned out, especially thanks to the talented artists and designers I had the privilege to work with. The reception has been gratifying; the Quarterly Review of Biology, for example, called it “spectacularly successful.” A number of courses have adopted The Tangled Bank both in the United States and abroad.

It’s hard to believe that four years have rushed by since the book came out. A lot has happened in the world of evolutionary biology during that time, some of which I’ve tried to document here and in my articles. And so, next month, I’ll be publishing the second edition of The Tangled Bank.

Dan Weston writes, “Given your interest in Moby Dick and tattoos, I thought you might appreciate my recent tattoo, based on an illustration by Rockwell Kent from the 1930’s edition (that I inherited from my grandmother and have read so many times that I had to have it rebound).”

Clearly, Dan has read my post from last year, “Herman Melville, Science Writer.”

For years I owned a copy of Moby Dick with Rockwell Kent’s dream-like engravings. The book disappeared a while ago, but the pictures remain how I see the story. The Plattsburgh State Art Museum has an online gallery of Kent’s illustrations here; I’ve reprinted the source of Dan’s ink below.

I think I need to buy myself another copy as a birthday present.

You can see the rest of the Science Tattoo Emporium here or in my book, Science Ink: Tattoos of the Science Obsessed.

In the pageant of life, we are genetically bloated. The human genome contains around 20,000 protein-coding genes. Many other species get by with a lot less. The gut microbe Escherichia coli, for example, has just 4,100 genes.

Scientists have long wondered how much further life can be stripped down and still remain alive. Is there a genetic essence of life? The answer seems to be that the true essence of life is not some handful of genes, but coexistence.

E. coli has fewer genes than we do, in part because it has a lot fewer things to do. It doesn’t have to build a brain or a stomach, for example. But E. coli is a versatile organism in its own right, with genes allowing it to feed on many different kinds of sugar, as well as to withstand stresses like starvation and heat.

I’ve lived in central Connecticut for ten years now, and so I missed their last emergence here in 1996. I was looking forward a June deafened by the songs of lovesick male cicadas, but my month turned out to be disappointingly quiet.

And yet, when my two daughters paid a visit to friends who live just seven miles away, they came home with a shoebox full of exoskeletons.

This year’s cicada emergence was anticipated by many millions of people in the eastern United States, but many of them missed it. But that doesn’t mean that the brood was a bust. Instead, it tells us something about they mysterious seventeen-year cycle of the cicadas.

In today’s New York Times I take a look back at Swarmageddon 2013, and look at what scientists learned about the bugs thanks to some newly invented tools. Check it out.

And see you next year in Iowa!
