The Flynn effect has always been tinged with mystery. First popularized by the political scientist James Flynn, the effect refers to the widespread increase in IQ scores over time. Some measures of intelligence - such as performance on Raven's Progressive Matrices in Des Moines and Scotland - have been increasing for at least 100 years. What's most peculiar is how scores have increased:

The time: the early years of the 19th century. The setting an ancient manor house in an isolated valley in the west of England. A scientist is engaged in a very elaborate series of experiments with electricity. Outside the laboratory, copper wires suspended on poles run for more than a mile into the countryside. Inside, mysterious equipment - coils of wire, weirdly shaped jars, strange crystals, saucers of murky liquid - glows and pulsates. The few local people who dare to approach the mansion tell of explosions, of bolts of lightning that strike when no storms are near, and of the reclusive, secretive nature of the scientist himself.

Intriguing article but frustratingly vague on the measurements used for intelligence testing. Apparently HARDI (High Angular Resolution Diffusion Imaging) can measure the diffusion of water through the brain, especially myelin. In yet another twin study (n=46 pairs) there appears to be a correlation between diffusion speed and intelligence.

MIT researcher Deb Roy wanted to understand how his infant son learned language -- so he wired up his house with videocameras to catch every moment (with exceptions) of his son's life, then parsed 90,000 hours of home video to watch "gaaaa" slowly turn into "water." Astonishing, data-rich research with deep implications for how we learn.
