Is Psychometric g a Myth?
- "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth
approaches 1. Usually the link is accompanied by an assertion to the effect that Shalizi offers a definitive refutation of the concept of general mental ability, or psychometric g

How do you build a mouse Utopia?
In 1972, John B. Calhoun
detailed the specifications of his Mortality-Inhibiting Environment for Mice: a practical utopia built in the laboratory. . . . To its members, the mouse civilization of Universe 25 must have seemed prosperous indeed. But its downfall was already certain—not just stagnation, but total and inevitable destruction.

Less than two weeks after a controversial paper came to light advocating the pre-natal treatment of some female fetuses with a hormone to make their behavior more stereotypically female (previously discussed here
) comes news of actual animal research on causing the opposite inclination. By knocking out the fucose mutarotase gene, scientists in South Korea have apparently created "Lesbian mice" who prefer other female mice and who resist the attempts of male mice to mate with them. Article abstract
, and coverage by The Telegraph

How disgusting can the inside of computer become? See now!
Some people smoke near their computers. Some people secrete their chip packets inside their computer boxes. You think you can get away with it until you need someone to find out why your computer is fucked up and then.. Ah hah! Could it be.. you have an alien fetus? Mice? The detritus of your fucked up lifestyle? All living within your box? Feel bad about yourself now!

MIT researchers can reverse some symptoms of autism and mental retardation in mice by suppressing a specific enzyme. The research, conducted at the Picower Institute for Learning and Memory
, is due to be posted on PNAS Online
some time this week. Here is the MIT article
. The specific symptoms reversed included hyperactivity, purposeless/repetitive movements, attention deficits and learning/memory challenges. The research was funded by the FRAXA Foundation
, the Simons Foundation
, the Wellcome Trust
, and the National Institutes of Health
. According to the CDC, the genetic causes treated by this particular technique (called FXS
) affects one in 4,000 males and one in 6,000 females of all races and ethnic groups. I would be interested in hearing about reactions that might be taking place in the various autism-related communities.

Hacking the Senses
: The brain is far more plastic than we commonly realize. Presenting new 'senses' via the old inputs works extremely well, to the point that long-term volunteers are a little lost without their new abilities to feel magnetic north or absolute orientation. Tasting direction; feeling pictures. Fascinating stuff. In a loosely related article, genetically modified mice
are able to see the full color range visible to humans, even though the last natural mouse able to see this way died out a hundred million years ago. Add the new sensors, and the brain reconfigures. [via]

I'm embarassed for my mice to have to say this but ... Their testicles are HUGE, like almost as big as their heads.
Good thing for humanity too, as mice testicles may provide a source of stem cells
free of the usual ethical considerations
.They may also hold the solutions to transplant rejection
. Is there anything those fuzzy globes can't do?

The Mars Gravity Biosatellite Project
is an unmatched international effort that pools top-notch technical talent from MIT, the University of Washington in Seattle, and the University of Queensland in Brisbane, Australia. The mission is nothing short of groundbreaking. The plan is to build a spacecraft capable of housing a small crew of mice, including pregnant females, which will simulate the gravity of Mars to determine its effects on mammalian development.

Mice and Martians!
Mice sent to Mars, first all-rodent space crew. I like the article's style:
"The crew will have no exercise wheels, however. Their motion would interfere with the centrifugal force inside the spacecraft."

Turning on a single gene
makes mouse brains grow huge, and fold in the skull similarly to human brains. Fancy discussing Derida over tea with a rodent? more inside...

3 Stench Ridden Days
"For almost 3 damned days I couldn't find what was causing this god-awful smell. All of my house mates and I were convinced that there was a rotting mouse either under the floor boards or in the wall. Well I say all my house mates except for James William Ascroft-Leigh, who suggested the smell was coming from my computer. I laughed and called him a fool, claiming that the computer surley wouldn't work with a dead mouse in it..."

Ebola is for wimps!
Some Australian scientists were trying to come up with a mouse contraceptive vaccine, for use in pest control. And they succeeded. Unfortunately, the virus they created works by killing mice before they can breed, and killing them very very well. Oh, and it's extremely vaccine-resistant: 100% death without vaccine, 50% with. And any kid with a Li'l Johnny Gene Engineering Kit could conceivably make a human version. Anyone got some smallpox virus laying around?
