A fair number of scientists like to get a tattoo to celebrate their research. Ryan Carney, a biologist at Brown University has taken the practice one step further. He’s gotten a tattoo that shows the key finding of a paper he and his colleagues have just published today. They studied a fossil feather from Archaeopteryx, the iconic bird (or almost-bird). They conclude it looked just like this tattoo.

Carney collaborated on the research with a team of scientists who have developed a method to reconstruct colors from fossils. One source of colors in animals is a cellular structure called a melanosome. Depending on the size, shape, and spacing of melanosomes, they can produce a range of hues. It turns out that melanosomes are incredibly rugged, sometimes enduring for millions of years.

In yesterday’s New York Times, I wrote about a new paper in which scientists report the evolution of single-celled yeast into multicellular snowflake-like “bodies.” Most (but not all) of the experts I contacted for the story had high praise for the study. (It also won an award when it was presented as a talk over the summer at the Society for the Study of Evolution.) Once the story appeared, however, some scientists took to Twitter to express their skepticism. As much as I like Twitter, this is one of the situations where it fails. You can’t have a conversation about genetics, lab strains versus wild types, etc., in 140 character chunks. At least not very satisfying ones.

In the history of life, single-celled microbes have evolved into multicellular bodies at least 25 times. In our own lineage, our ancestors crossed over some 700 million years ago. In tomorrow’s New York Times, I write about a new study in which single-celled yeast evolved into multicellular forms–completely with juvenile and adult forms, different cell types, and the ability to split off propagules like plant cuttings. All this in a matter of weeks.Check it out.
