Mendel’s Garden #18

Mendel’s Garden is the original blog carnival devoted to genetics. A new carnival is traditionally posted on the first Sunday of the month (although the date is somewhat flexible). The newest edition of Mendel’s Garden has been posted at balancing life. Sandy at Discovering Biology in a Digital World will be hosting the next edition.…

That Crab Has Flies

Among my many pet peeves are when people refer to Drosophila as fruit flies (they are not). Real fruit flies (Tephritids) feed, mate, and lay their eggs on live fruit — for this reason, many are agricultural pests (e.g., the medfly). Drosophila, on the other hand, feed on the micro-organisms found primarily on rotting fruit…

Craig Venter, Sequenced

Lookie here — they’ve sequenced Craig Venter’s genome. What did they learn about Craig? Well, he’s European. He has 46 chromosomes. He’s got some structural differences from the reference genome. Venter also differs from the reference genome by insertions and deletions.Like every other human, he’s got a boat load of repetitive sequences in his genome.…

Promoting Intelligence

A new article in Nature Genetics brings together two themes that I’ve blogged about before: human brains and King and Wilson. In fact, I’ve even already blogged about the article, but this post contains a more thorough treatment of the science. The long and short of it is that some people think that differences in…

Genomfart

Massimo Pigliucci has reviewed Mike Lynch’s book on genome evolution for Science [Postgenomic Musings]. In his review, Pigliucci writes the following: One of the central theses of the book is that natural selection is not necessarily the central evolutionary mechanism, as quite a bit of the details of genomic structures and evolution can be accounted…

Remember when I said that the near future of eukaryotic genome sequence would involve sequencing EST libraries (collections of mRNA, or transcribed genes) rather than de novo sequencing of whole genomes? Well, I did, even if you don’t remember. Anyway, a new paper in PLoS ONE puts that approach to the test for the purpose…

Lamarck was Wrong

Shelley’s posted some pictures of nerd cakes. She calls ‘em geek cakes, but I see no headless chickens. Anyway, I’ve got my own little nerd cake: We had it made for a party we threw during recruitment weekend for our grad program this past spring. Sadly, the icer responsible for the art couldn’t spell, so…

Genomic Phylostratigraphy

According to this press release Trends in Genetics (TIG) is “the most established monthly journal in Genetics”. I have no idea what that means, but if I were asked to name the top journals in genetics, TIG wouldn’t crack the top four. In fact, here is my top four: Nature Genetics PLoS Genetics Genetics Heredity…
