The Canadian research organization Genome BC has unveiled a science education website, Genomics Education. One of the features of the website is Floyd the Fruit Fly, who, we can only presume, is some sort of cartoon drosophilid. Or maybe he’s a tephritid, but I highly doubt it. When you hear “fruit fly” and “genetics”, you…

Gonads and Sperm

Spring is in the air. The obvious signs are everywhere: the temperature is rising, the flowers are blooming, and everyone’s writing about boners. There’s this post from Darren Naish on turtle gonads, and Carl Zimmer has an article on duck phalluses (don’t call them penises, as Darren explains) in the NYTimes (and a blog post…

Genetics of Speciation

The most recent issue of the Journal of Heredity contains a bunch of articles from a symposium on the “Genetics of Speciation” organized by Loren Rieseberg. Included in the collection is an article by Allen Orr and two of his students on speciation in Drosophila, which discusses mapping speciation genes, the role of meiotic drive…

Flying in a Confined Space

On yesterday’s episode of Mythbusters they tested the myth that birds in a trailer decrease the weight of the trailer when the birds take flight. The ‘busters put a bunch of birds into a trailer, weighed the trailer + birds, and then allowed the birds to fly in the trailer, measuring the weight every fraction…

Dan Hartl’s Inaugural PNAS Article

Dan Hartl was inducted into the National Academy of Sciences of the USA in 2005 for his contributions to the field of evolutionary genetics. His inaugural article as an Academy member was published this week in the Proceedings of the National Academy of Sciences (PNAS, pronounce pee-nas, hehe). Hartl and colleagues compared levels of polymorphism…

If it’s not human, it’s crap!

Those of us who work on non-human systems often grumble about the total disregard human geneticists (that’s geneticists who study humans, not humans who are geneticists) have toward non-human research (that’s research on non-humans, not non-humans doing research). I get the feeling that plant biologists have the same attitude toward non-plant researchers, and I imagine…

Hitching a Ride on a Drosophila Genome

Not all regions of the genome are equal in the eyes of evolution. For example, natural selection is more effective on genes in regions of higher recombination. We have known this for a while. The connection between recombination rate and natural selection was nicely refined when it was shown that DNA polymorphism is lower in…

This post is part of a series documenting Professor Steve Steve‘s recent visit to Philadelphia for the Drosophila Research Conference (aka, the Fly Meeting). Professor Steve Steve had a wild Saturday night. He was quite happy to have met leaders in the fields of evo-devo, population genetics, and genomics. Of course, Steve Steve is a…

This post is part of a series documenting Professor Steve Steve‘s recent visit to Philadelphia for the Drosophila Research Conference (aka, the Fly Meeting). In the previous two installments of Steve Steve in Philly, we finally managed to meet up despite the best efforts of the staff at the Marriott to prevent our rendezvous, and…

This post is part of a series documenting Professor Steve Steve‘s recent visit to Philadelphia for the Drosophila Research Conference (aka, the Fly Meeting). After tracking down Steve Steve in the lobby of the hotel on Saturday, we picked up some food at the Reading Terminal Market — a permanent sort-of-farmers-market next to the Philly…
