Drinking and Intelligence

The next time you're inclined to enjoy an extra glass of wine, consider that it may be a reflection of your intelligence. That is one of the findings from data from the National Child Development Study in the United Kingdom and the National Longitudinal Study of Adolescent Health in the United States.

Childhood intelligence, measured before the age of 16, was categorized in five cognitive classes, ranging from "very dull," "dull," "normal," "bright" and "very bright."

The Americans were revisited seven years later. The British youths, on the other hand, were followed in their 20s, 30s and 40s. Researchers measured their drinking habits as the participants became older.

More intelligent children in both studies grew up to drink alcohol more frequently and in greater quantities than less intelligent children. In the Brits' case, "very bright" children grew up to consume nearly eight-tenths of a standard deviation more alcohol than their "very dull" cohorts.

Researchers controlled for demographic variables, such as marital status, parents' education, earnings, childhood social class and more, that may have also affected adult drinking. The findings held true that smarter kids were drinking more as adults.

Psychology Today takes an evolutionary approach. It argues that drinkable alcohol is a relatively novel invention of 10,000 years ago. Our ancestors had previously received their alcohol kick through eating rotten fruits, so more intelligent humans may be more likely to choose modern alcoholic beverages.

Although increased alcohol consumption could be a reflection of exceptional brainpower, drinking more will certainly not make you any more intelligent than you already are. I'll drink to that.

Intel Newest Computer Chip

Intel announced on Feb 8 its newest Intel announced its Itanium 9300 series microprocessor, a high-end supercomputing chip with 2 billion transistors on a single chip. The number of transistors, or basic on-off switches that control the flow of electrical signals in a chip, is about twice as much as what Intel and other big companies normally put in a chip.

Curiosity and Intelligence

If you are reading Friday Thoughts, you are probably a curious person. Well, here is some good news. It also means that you are likely intelligent. Something we all knew, but now science is on our side.

Scientists from University of Toronto and the Samuel Lunenfeld Research Institute of Mount Sinai Hospital have discovered a molecular link between intelligence and curiosity.

Sep, 2009, the journal, Neuron published results from researchers, who studied the interaction of two proteins in a small region of the brain in the hippocampus, which plays an important role in long-term memory and spatial navigation.

For the study, the neuronal calcium sensor-1, a protein was increased by one-and-a-half times in mice. This modest overexpression increased the ability of brain cells to change how they communicate with each other and gave the mice superior memory in complex tasks and a significant increase in exploratory behavior (curiosity).

The scientists believe they have discovered a region of the brain that generates curiosity and a model for how brain activity leads to curiosity. They believe that fostering curiosity should also foster intelligence and vice versa, which may lead to the development of drugs to improve learning. I'm curious, when can we get some of those drugs?
