From Sex, Genes and Evolution, a story of publishing in PLoS Open Access Journal: My lab has taken its initial journey on the PLoS ONE train. Yesterday, our paper entitled “An Expanded Inventory of Conserved Meiotic Genes Provides Evidence for Sex in Trichomonas vaginalis” was published in PLoS ONE. It’s a updated and detailed report…

PZ Myers‘ appearance on Atheist Talk Radio was positively Orwellian. Host Mike the Madman Haubrich actually asked PZ about developmental biology (evodevo). Fish embryos? What about crackers!!!! I wanted crackers!!!! And I get Zebrafish! The interview was actually very interesting, in which PZ discussed homologous structures in the mouse and the bat, in reference to…

The Evolution of Imprinting

The phrase “genomic imprinting” has come to refer the turning off of a gene (a particular instance of a gene on a particular chromosome duplicated across the cells in a body) so that the gene is not expressed at all, with the turning off of the gene not caused in the body in question, but…

The Perfect Bird Family Tree…

… is certainly still in the future. But we have seen a step in that direction in a new paper, coming out this week in Science. This research applies intensive and extensive genomic analysis to the avian phylogenetic tree. The results are interesting. This paper is summarized in a number of locations, most notably here…

Genome Size and Flight in Bats

Continuing with our discussion of the Evolution 2008 conference, I was hoping to meet T. Ryan Gregory yesterday. He is listed on the Evolution 2008 program as an author of a talk on genome size. Goodnews/badnews: Gregory did not show, but the talk, given by his coauthor working in his lab, was excellent, so we…

The Evolution 2008 conference started out today with a special program for K-12 teachers (mainly life science teachers) organized by the Minnesota Citizens for Science Education (MNCSE). The opening speaker was Scott Lanyon, director of the Bell Museum of Natural History. (The Bell hosted this event.) Scott’s objective was to outline several areas of evolutionary…

Photograph of Francis S. Collins Just passing along the details from Associated Press: WASHINGTON (AP) — The government is losing its gene guru: Dr. Francis Collins, who helped lead the breakthrough unraveling of the human genetic code — and found common ground between the belief in God and science — is resigning. Collins, arguably the…

Could even this bird be reanimated, gene by gene? When you are extinct you’re extinct. Everything about you is dead and gone. There are no more of you, every individual in your species is kaput, non existent, used up, as the Pima Indians would say, you are hokum (like a car with a flat tire).…

A recent study of dog genetics, published in PLoS, seeks to improve the quality of genetic research by better understanding the underlying patterns of genetic variation at the level of specific dog breeds.

Amazing DNA

Great enunciation in this one:
