Dyslexic rats? Really? Well, these rats can’t read, but they’re still used as an animal model for dyslexia.
First, some background. The underlying cause of dyslexia is still under debate, but it’s generally accepted that it involves deficits in auditory and phonological (language sounds) processing, with a possibility of visual deficits as well. Post mortem

Biological fitness includes a measure of both survival and reproductive ability – one is not nearly as important without the other. So what happens if the ‘unfit’ members of a population are suddenly the ones with all of the reproductive power?
This kind of absurdity can only happen when nature gets a little ‘help’ from humankind.
Eutrophication [...]... Read more »

I recently attended the DISCCRS symposium for recent PhDs of a wide variety of disciplines whose work (past or present) deals with climate change. The week-long meeting was phenomenal, seeding me with thoughts, ideas, and basically making me feel quite good about the work I’m doing (if also very pessimistic about how society is [...]...

You don't have to look far to find mutterings about the peer review system, especially about the ways in which anonymous reviewers might hold up your paper or harm your career. On the other hand, there are plenty of champions of the status quo who argue that anonymous peer review is the essential mechanism by which reports of scientific findings are certified as scientific knowledge.
So how do scientists feel about anonymous peer review? A 2008 paper in Science and Engineering Ethics by David........ Read more »

In an intriguing political story, it seems that Switzerland is on the verge of voting in legal representation for all victim animals.

It’s been roughly 80 years since the red imported fire ant (Solenopsis invicta) arrived from South America to Mobile, Alabama in soil used as ballast to weigh down boats. Needless to say, fire ants have adapted well in southern states like Texas, Louisiana and Florida, disrupting native wildlife and plants and causing problems for people ranging from shorting out street lights to stinging limbs.
But in the late 1990s and early 2000s, scientists brought over several strains of parasitoid........ Read more »

In the past few years several prominent researchers have argued for the adoption of taxes on junk food as a means of reducing their consumption. Often, as in a recent editorial in the New England Journal of Medicine, the argument is made that money collected through the tax could then be used to subsidize healthier foods. This is an idea that I've found very appealing - we make the bad foods more expensive, the good foods less expensive, and people will probably shift at least some of their p........ Read more »

Davidson et al. published another study a few weeks ago in Ecology further exploring the relationships between black-tailed prairie dogs and their much maligned neighbors, Bos taurus, cattle. Prairie dogs have been generally regarded as a danger to cattle by ranchers and removed through poisoning or other means. Overgrazing can lead to desertification, further threatening these animals. But that's a relatively new trend in a long and complex history of interaction between prairie dogs and m........ Read more »

Domestication is by far man's greatest genetic experiment, and we've been at it for well over 10,000 years. While domestication can produce wild variation (see my post on dogs, for example), a few changes seem to be universal. These include behavioral changes, like reduced fear of humans and friendliness, as well as physiological ones, like floppy ears (they develop in domesticated foxes, too). One of the most well-documented differences between domesticated animals and their wild counterparts i........ Read more »

The partial faces of Anoiapithecus (left), Pierolapithecus (center), and Dryopithecus (right). (Images not to scale)
Our species is just one branch of a withering part of the evolutionary tree, the great apes. Along with the handful of species of chimpanzees, gorillas, and orangutans, we are all that is left of the hominids, and considering the threats our close relatives face we could very soon be the only great apes left. It has not always been this way. During the swath of prehistory ~2........ Read more »

My recent focus on the lack of genetic continuity between hunter-gatherer and farming populations genetically and culturally is primarily due to the fact that we’re not in theory-land; the extraction of ancient DNA samples is steady-as-it-goes and is sharpening and overturning our understanding of the past. The relationship between culture and genetics is of [...]... Read more »

It is well known that plant populations do best when they grow close to where they originally came from.
