Geese, Ganders, and Genomes

I previously described where in a genome we would expect to find sexually antagonistic genes. Briefly, depending on whether a gene is male-biased or female-biased and whether beneficial mutations are dominant or recessive, we can predict whether these sexually antagonistic genes will be on X chromosomes or autosomes. As I mentioned in that post, the…

Make that 12 Drosophila Genomes

What happens when I mention a paper describing two more Drosophila genomes? Well, I get a comment telling me that the 12 Genomes Papers have gone live over at Nature. They have provided a nifty 12 Genomes Portal for us to navigate the articles published by Nature based on data from the 12 Genomes Project.…

Publishing Original Research on Blogs – Part 1

This is a repost (with some edits) of an introduction to publishing original research on blogs — a series I am reintroducing. The original entry can be found here. In April of last year, Bora pushed the idea of publishing original research (hypotheses, data, etc) on science blogs. As a responsible researcher, I would need…

Multicellular Eukaryotic Genomes are Teh Suck

The human genome is one big, bloated motherfucker. It’s almost all non-protein-coding DNA. The same is true for many other eukaryotic genomes. Sure, some of it has a function. But a whole lot of it (and maybe most of it) is just junk. There are some who point to a relationship between genome size and…

Over a year ago I threatened to perform some original research and publish it on my blog. I got as far as writing an introduction to the project, but I never actually posted any data. I know, I suck.I had hoped to make the project simple enough that people could follow along. The problem was…

Carl Zimmer has a post covering three recent papers on gene duplication: one on amylase variation in humans, one on whole genome duplication in yeast, and one on duplications of genes in the Drosophila arizonae reproductive tract. In all three papers, results are presented showing the importance of duplicated genes in adapting to the environment.…

Family Values

I’m sure by now you’ve heard of the ginormous spider web that was spun in Texas. The thing was huge — 200 yards long — and it was spun by multiple different species. That interspecific collaboration got Bill Poser thinking, so he blogged about it at Language Log: The web covers hundreds of square meters.…

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…
