Well, cool. We’ve got preliminary analysis of the octopus genome, and it’s full of tantalizing goodies, but it’s very preliminary, and the Nature news and comment left me unimpressed. One of the things they seemed to think was a big deal was that Octopus has more genes than we do. Surprisingly, the octopus genome turned…

What’s going on, Scotland?

Scotland is going to formally ban the cultivation of genetically modified crops. Apparently, this was an easy step for them to take, because it’s the scientists who are explaining that this is a foolish move, and everyone knows you can just ignore the scientists. I also think it’s a matter of fearing the unknown. Scotland…

A defense of ENCODE?

Dan Graur has snarled at the authors of a paper defending ENCODE. How could I then resist? I read the offending paper, and I have to say something that will weaken my own reputation as a snarling attack dog myself: it does make a few good points. But it’s mostly using some valid criticisms to…

Death to Dollo’s Law!

Hint for science journalists: if the hook to get readers to pay attention to your story is to warn them to sit down because a 19th century “law” of evolution has been shown to be wrong, you’re going to irritate scientists, who will then write rude blog posts sneering at your writing. That’s the case…

The genetic load problem

Dan Graur has written a good summary of genetic load. It’s an important concept in population genetics, and everyone should be familiar with it…and this is a nice 2½ page summary with only a little math in it. I’ll try to summarize the summary in two paragraphs and even less math … but you should…

On the importance of luck

That paper that proposed that most cancers were due to bad luck, that is, that they were a consequence of biological factors that could not be controlled, has been surprisingly controversial. I thought it was a fairly unsurprising paper that confirmed what we already suspected, but wow, the furious pushback has been something to behold.…

Let’s slap ENCODE around some more

Since we still have someone arguing poorly for the virtues of the ENCODE project, I thought it might be worthwhile to go straight to the source and and cite an ENCODE project paper, Defining functional DNA elements in the human genome. It is a bizarre thing that actually makes the case for rejecting the idea…

Crusaders against GMOs

The New Yorker has a fascinating article on Vandana Shiva, a crusader against GMO crops. I’d never heard of her before, but apparently she has charisma and cult-like followers who hang on her every word, and her word is a rather religious opposition to scientific agriculture. Weirdly, I can agree with some of it. At…

Learning thresholds

Kim Goodsell was not a scientist, but she wanted to understand the baffling constellation of disease symptoms that were affecting her. The doctors delivered partial diagnoses, that accounted for some of her problems, but not all. So she plunged into the scientific literature herself. The point of the linked article is that there is a…

I like this hypothesis

But we have to be clear that it is only a hypothesis at this point. I was reading about domestication syndrome (DS) — selecting animals for domestication has a whole collection of secondary traits that come along for the ride, in addition to tameness. We are selecting for animals that tolerate the presence of humans,…
