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

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...

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?
