From Cosmic Variance, a very very short but oddly reassuring blog post: What Should I Say if Someone Asks Me, "Will the Large Hadron Collider Destroy the World?"
Genomicron on Phylogenetic fallacies: "early branching equals primitive".
Evolutionary trees, or "phylogenies", are a major part of modern evolutionary science. They depict hypotheses regarding the relationships among taxa, and are therefore important in reconstructions of the historical path of evolution (Gregory 2008a,b). Various approaches can be taken to formulating phylogenetic hypotheses, including analyses based on morphological, fossil, and/or molecular data. These methods often agree well, but sometimes one or another can throw up some surprises and challenge previous hypotheses about the relationships among groups of organisms.
The Scientific Activist covers the question Why Are Veins Blue?, in a blog on peer reviewed research that you must read. This is closely related to the question: Is Blood Ever Blue? Science Teachers Want to Know!
Chris Rowan at Highly Allochthonous has a great post on impact craters and their meaning: How big was that asteroid? The latest geochemist/geophysicist smackdown. This is very informative and, among other things, explores a disagreement between subfields in science.
I've always wondered this: How do bats in a cave know if it is dark outside yet? Guest post by Anne Marie Hodge. This is an excellent guest post over at A Blog Around the Clock.
Expelled! the dumb movie is coming out tomorrow. I've already declined one invitation to go see it (and the person who asked me has actually declined himself as well, apparently). So, would you pay to see this movie? Read this first: To See Expelled or Not: How Religion Leads to Atheism, Not Evolution
And this, just in: A dialogue on pseudonymity, personae, and interpersonal relations in the blogosphere.
