I will be hosting the next edition of Mendel’s Garden on Sunday, November 2. If you have written any blog posts about genetics in the past few months, send me a link (evolgen[at]yahoo[dot]com). Also, if you’ve seen any good genetics posts on other people’s blogs, let me know. For those not in the know, Mendel’s…

They are NOT fruit flies

In the recent kerfuffle over Sarah Palin’s disparaging remarks about “fruit fly” research, an important point was missed by the general public, scientists, and even Drosophila geneticists: she wasn’t talking about Drosophila. Now, this point has been clarified by a few people (notably Mike the Mad Biologist), and I think people are starting to get…

Get Your Masatoshi Nei Trading Card

The Penn State Alumni Association has produced trading cards featuring the best and the brightest of the university’s faculty (Pa. trading cards highlight brains, not brawn). The cards are only available at University President Graham Spanier’s tailgate parties on home football weekends. The biologists featured include entomologist Jim Tumlinson and molecular evolution pioneer Masatoshi Nei.…

Inspired by the Sarah Palin Debate Flow Chart, here’s the Seminar Answer Flow Chart:

Slightly Deleterious in Trans

One of the hot topics in evolutionary biology concerns the relative contributions of protein coding sequence changes and non-coding changes that lead to differences in the expression of protein coding genes. A subset of this debate can be summarized as cis versus trans. Non-coding sequences that regulate gene expression are known as cis regulatory elements…

Mendel’s Garden #25 — Call for Submssions

I will be hosting Mendel’s Garden #25 at evolgen. That’s right: the carnival is back! Mendel’s Garden is the original blog carnival devoted to genetics. Submit your genetics related posts to evolgen[at]yahoo[dot]com. Because Mendel’s Garden has been dormant for the past few months, I’ll be accepting posts written from March through October. So, dig through…

Adaptationist Junk

The human genome (like all mammalian genomes) is loaded with sequences that don’t perform any known function. And many of these sequences are junk. And it’s not just mammals — many animal genomes are loaded with junk, as are those of other eukaryotes. That’s not to say that some of the sequences of unknown function…
