1. From this week’s crop of new tattoos: Abraham writes: “I got mine in grad school (PhD materials science and applied physics, 2004 Cal). The tatoo is a convergent beam electron diffraction (CBED) image of 6-4 Ti alloy (hexagonal, or beta phase) one of the first ‘super alloys’. Being light-weight, high-strength, and corrosion resistant, I felt it was appropriate to put on my back, to keep it strong.”

2. We are now actually inspiring people to get new science tattoos. Janet Stemwedel, my estimable fellow scienceblogger, send the following request:

This is a new and fascinating map. It shows how next spring is probably going to come early here in New England, as it has come earlier and earlier for the past few decades. But in Florida it will probably come late. Both changes stem from the same source: our carbon addiction. I explain why in my first foray in a new column for Wired.com called Dissection. The column, on all manner of science, will come out every other Friday. Let me know what you think, there or here.

A couple weeks ago I mentioned that I’ll be teaching a workshop in January at Yale about science writing. The response has been fantastic, with 90 people signed up at my last count. What makes the response particularly interesting is that a couple subjects of my own articles (like this) will be coming. So I may get them to talk a little about what it’s like to be on the receiving end of the media machine.

Several readers have expressed dismay that they couldn’t come. I’m happy to report that at least part of the workshop will be recorded and turned into a podcast that will be available for free at the Yale Itunes site. I’ll let you know when it’s ready.

Every Spring, the Earth blooms. Scientists call it greenup: New buds sprout, fresh leaves unfurl, and continents turns green.

Exactly when greenup takes place each year is the result of an algorithm embedded in the DNA of plants. They track the rising temperature in spring, gauge the rainfall, measure the lengthening days, and then calculate when to start growing.

People have been trying to figure out the greenup algorithm for millennia. Farmers needed to know when to plant their crops; herders needed to know when pastures would be ready for their herds. In China and Japan, greenup records reach back 5,000 years.

About half a billion years ago, our ancestors were slender, jawless, fishlike creatures. Their backs were stiffened by a rod of cartilage, along which grew bony prongs. That smattering of bone was the forerunner of our vertebrae, and it gave us and all the other descendants of those ancient animals our name: the vertebrates. Vertebrates have evolved into tens of thousands of species dominating the ocean, land and sky. Much of their success is due to the many new forms their skeletons have taken. A new coffee-table-format book, “Evolution” (Seven Stories Press), offers hundreds of gorgeous photographs of those forms, as diverse as bats with fingers thinner than pipe cleaners and rhinos with skulls as stubborn as boulders.
