Genes Reveal Recent Human Brain Evolution. Two important new papers in the journal Science (available here) from the evolutionary geneticist and rising star, Bruce T. Lahn (see this recent profile from The Scientist), are potentially the tips of some very large icebergs. The papers document how two genes related to brain properties that underwent strong selection during the course of hominid evolution, have continued undergoing strong selection since the emergence of anatomically modern man. The papers wonderfully illustrate how biological evolution is an ongoing process as well as the artificial distinction between “micro” and “macro” evolution, and promise to be controversial for two reasons: First, the brain genes underwent the strongest selection during two periods of cultural and technological efflorescence (roughly 37,000 and 5,800 years ago). Second, the genes are distributed very differently in modern human population groups, existing at very high frequencies in some groups and being very rare in others, ensuring that the modern function of these genes will be a source of more research and much impassioned debate. More observations from anthropologist John Hawks.

Human Intelligence is a good site from Indiana University that looks at historical influences and current controversies surrounding the study of intelligence. Find out more about topics such as "the Mozart Effect", the theory of multiple intelligences, and the influence of birth order on intelligence, and then browse the brains behind the history of inquiry into human intellect.

Nootropics ("smart" drugs) - all wish to be smarter, correct ? And - while exercise, nutrition, learning, travel, and social interaction (the last 3 via release of neurotrophins) effectively do this, Nootropic drugs have been researched since the 1950's and have been shown to cause at least short term cognitive function enhancement. Piracetam, the first of this drugs, shows promise in the treatment of Alzheimer's and Attention deficit Disorder. Alas, as with poor little Algernon, the effect seems temporary. Nootropics can be a little difficult to acquire in the US. Beer is not a nootropic, but sex on the other hand.....

Cultured Apes: According to a study published in today's issue of the journal Science, orangutans have been passing on a shared culture for generations (free registration required to view entire study). To what degree are animals intelligent? Are primates more intelligent than other animals? What about crows and ravens? (My favorite subject of animal intelligence studies is still Koko the gorilla.)

Musicians are really smart. They have larger and more sensitive brains than non-musicians, and their collective IQ is much higher. They have 130% more grey matter in one area of their auditory cortexes. The question of how this explains Ozzy Osbourne nonwithstanding, I'll bet if you're really, really smart, you could be one of the new members of Men Without Hats. Must be very knowledgeable in midi, sequences, and sampling.

Is intelligence hereditary or environment? A new theory sees the brain as a plastic mold of potential with the more neuron connections the better [hereditary] and environment stimulation shapes the mold untill maturity. "You could present a person with an IQ of 200 with the appropriate phenomena when they are 20 years old, after the critical learning period, and they would not have the capacity to adapt their brains to the new phenomena". People of low IQ perform poorly because their brains do not adapt well to environmental stimulation.

Playing computer games makes kids smarter? Although it reads like a headline from The Onion, a British study funded by the ESRC has come to that conclusion. "They seemed able to focus on what they were doing much better than other people and also had better general co-ordination. Overall there was a huge similarity with top-level athletes."

Gotta go and show this to my boss...

project delphis
an organization called earthtrust started project delphis in 1985 to determine how intelligent and self-conscious dolphins actually are. this is very cool.
