The latest version of Tangled Bank - Tangled Bank #51: the Seattle Tour!, is online at Discovering biology in a digital world.
What is Tangled Bank (from http://tangledbank.net/):
Welcome to the Tangled Bank, a version of the "Carnival of the Vanities" for science bloggers. A Carnival is a weekly showcase of good weblog writing, selected by the authors themselves (that's the vanity part). Every other week, one of our crew will highlight a collection of interesting weblog articles in one convenient place, making it easy for everyone to find the good stuff.
Two things will distinguish us from the original "Carnival of the Vanities": 1) we are specifically restricting ourselves to articles in the field of science and medicine, very broadly defined, and 2) we've got a different name. Our weekly compendium of great science weblog articles will be called the Tangled Bank, after Charles Darwin's famous metaphor.
