I just took a survey about blogs about science, and you should too. Here’s the description:

This survey attempts to access the opinions of bloggers, blog-readers, and non-blog folk in regards to the impact of blogs on the outside world. The authors of the survey are completing an academic manuscript on the impact of science blogging and this survey will provide invaluable data to answer the following questions:

Who reads or writes blogs?

What are the perceptions of blogging, and what are the views of those who read blogs?

You may be familiar with Pulse of the Planet as a radio show about nature, but Jim Metzner, its producer, just let me know that it now sports a pretty extensive web site, including a selection of diaries from scientists studying everything from lightning to sea turtles. Check it out.

“Attached is a photo of a tattoo I got immediately after turning in the final paperwork a little over two weeks ago for the completion of my Ph.D. in biological anthropology. It’s the first evolutionary tree that Darwin sketched in his 1837 Notebook B on the transmutation of species.” –Julienne

We’re up to 64 tattoos in the flickr set, which has been seen by over 96,000 people since I set it up last month (which doesn’t count the 130,000+ pageviews of the original post). I think I’ll just post my favorite of the week each Friday until people stop sending them to me.

The bloggers here at Scienceblogs all have other professional lives–professors, doctors, software engineers, and so on. My own line of work as a science writer can make blogging a bit awkward every now and then. Take, for instance, an article I wrote for tomorrow’s New York Times about moray eels. It turns out that they have bizarre jaws hidden in their throats that catapult forward into their mouth to grab prey.

What do human spit, baker’s yeast, and fly sex have in common? Together, they illustrate a way in which new kinds of genes evolve.

Scientists published a paper in Nature Genetics Sunday in which they studied an enzyme called amylase that’s produced in saliva and breaks down starch. Human amylase genes share a common ancestry with the amylase gene found in our close relative, the chimpanzee. But they are different in some important ways. Instead of one amylase gene, we have several. Human amylase genes range from 2 to 15 copies, averaging three times as many as chimpanzees.
