This cat is going to be insufferable

(a) Orthologous gene clusters in mammalian species. The Venn diagram shows the number of unique and shared gene families among seven mammalian genomes. (b) Gene expansion or contraction in the tiger genome. Numbers designate the number of gene families that have expanded (green, +) and contracted (red, −) after the split from the common ancestor. The most recent common ancestor (MRCA) has 17,841 gene families. The time lines indicate divergence times among the species.

You may have heard we’ve got this satanic feline padding about the house now, getting into mischief — she has discovered my collection of cephalopodiana, and her favorite toy is one of my stuffed octopuses that she wrestles and bats around the floor. It’s like she’s rubbing it in. Anyway, a new paper in Nature …

Magic RNA editing!

old-wrecked-car-outback-australia-14466708

One of those wacky Intelligent Design creationists (Jonathan McLatchie, an arrogant ignoramus I’ve actually met in Scotland) has a theory, which is his, to get around that obnoxious problem of pseudogenes. Pseudogenes are relics, broken copies of genes that litter the genome, and when you’ve got a gang of ideologues who are morally committed to …

Short, sharp summary

Larry Moran has a simple list of the 5 basics you need to understand about junk DNA. It’s short and sweet; I’d like to see a creationist, who are often weirdly antagonistic to the whole idea of junk DNA, deal with these basic facts before they start ranting against the observations and conclusions. Genetic Load …

The MFAP Hypothesis for the origins of Homo sapiens

I know you’re thinking we’ve had more than enough discussion of one simplistic umbrella hypothesis for the origin of unique human traits — the aquatic ape hypothesis — and it’s cruel of me to introduce another, but who knows, maybe the proponents of each will collide and mutually annihilate each other, and then we’ll all …

Do the creationist shuffle and twist!

Don’t you hate it when you get up in the morning and the first thing you read on the internet is the news that your entire career has been a waste of time, your whole field of study has collapsed, and you’re going to have to rethink your entire future? Happens to me all the …

I’m a professional “biologist”!

newknowoldass

Vox Day/Theodore Beale really is hilariously easy to trigger into paroxysms of foolishness. He now refers to me as a professional "biologist" in those lovely scare quotes, because he thinks his understanding of “genetic science” is better than mine. He explains what he meant by his remarks that he, a white man, and NK Jemisin, …

The Supreme Court decision on patentable genomes

I’m shocked. Just totally surprised. And it was unanimous — the Supreme Court determined that human genes cannot be patented. This is excellent news. Why is it a good decision? Because medical DNA analysis was turning into a patchwork of competing landgrabs. Sequencing technology is coming along so nicely that more and more diagnostic tools …

The first day of the rest of my summer!

twitch

It’s going to be a good season, I can tell already. It’s finals week, so I’ll still have an abrupt pile of grading to do on Thursday, but otherwise, my teaching obligations are done for the semester. Now I’m trapped, trapped I tell you, in Morris for almost (I do have two quick trips to …

Musings from the mind of a mouse

coel_Ig_phylo

Casey Luskin is such a great gift to the scientific community. The public spokesman for the Discovery Institute has a law degree and a Masters degree (in Science! Earth Science, that is) and thinks he is qualified to analyze papers in genetics and molecular biology, fields in which he hasn’t the slightest smattering of background, …

Junk DNA in the coffee shop

JunkDNACafeScientifique

I’m giving you a heads-up in advance: the last Cafe Scientifique in Morris for the school year is next Tuesday, the 30th, and you-know-who is giving it. I expect to see you all there. If you’re not, don’t come around asking me for a Christmas present later.
