In 2005, researchers made headlines when they reported that they had found intact blood vessels from a 68-million-year-old Tyrannosaurus rex. The discovery raised hopes that paleontologists could get their hands on the flesh and blood of vanished animals. This week, however, other scientists challenged the results, arguing that the dinosaur flesh was in fact just coatings of young bacteria. But the original researchers stand by their results, calling the new argument weak. “There really isn’t a lot new here,” says Mary Schweitzer of North Carolina State University in Raleigh.

I’ve been offered a few islands to do my work.

Craig Venter said this in passing, almost under his breath, as he spoke Wednesday night about the future of biology at the Oxonian Society in New York. It was a perfect Venterism. Venter, of course, is the scientist who declared he would lead a project to sequence the human genome faster, better, and much cheaper than the official government effort. He’s the guy who then had the audacity last year to publish the most accurate genome sequence to date–his own.

If you’re new to the Loom, you may not be aware that I have a thing for science tattoos. It’s been exactly a year since I noticed a tattoo on the shoulder of a friend who’s a geneticist at Columbia. The tattoo was DNA, and it spelled his wife’s initials in the genetic code. So I wondered aloud if there were other scientists who had inked themselves with science, and the answer was a shockingly loud yes. In fact, I was soon inundated with so many pictures of tattoos (and enlightening stories behind them) that I had to separate them from my old blog to keep them organized. The tattoos have become fodder for stories in places like New Scientist and Wired. Now that the Loom has arrived at Discover, I’m bringing them back into the fold.

Just a quick note: over to the right you’ll see a blog roll of some of my favorite blogs. I’m having a little trouble dumping all my favorite blogs at once into the right place on the back end, so I’ll just add them now and then. Today’s addition is a baby blog–The Rough Guide to Evolution. It’s by Mark Pallen, a British microbiologist and evolutionary biologist I’ve interviewed several times (see this National Geographic article for starters). You may also know Mark for his Origin of Species dub. Despite having his hands full (see image), Mark has just hammered out an eponymous book that will be published at the end of the year, and he promises to post on his blog every day till then…and beyond? Anyway–check it out.

Scott writes,

“I have my BS degree in Computer Science from East Carolina University, where I currently work as a software engineer. Here is a picture of my Computer Science tattoo. It is of the question P=NP. This unsolved equation is considered by many to be the Holy Grail of Computer Science. Ever since I came across it in a Computability class, its possibilities and implications have fascinated me. I realize that many believe that P!=NP. To those I say “Prove It” (and be sure to remember me when you collect your Million dollar prize from the Clay Mathematics Institute).”
