Learning to play a musical instrument can increase a child's IQ. (Note: this is different from the now-debunked "Mozart effect" in which some people claimed the merely listening to a lot of classical music as an infant or child would increase IQ.)

Computer models of traffic on the mean streets of Bogota, Colombia reportedly show that aggressive driving can reduce traffic congestion, albeit at the price of an increased death rate from motor vehicle collision. (This data doesn't explain why traffic is still so horrible in Boston, Massachusetts, where the drivers are extremely aggressive...)

Invention of the day: New childproof medicine containers that rely on mental dexterity rather than physical strength. Given that a recent study showed that up to 90% of adults had trouble with current childproof packages, this could be step in the right direction.

Insecure password horror story of the day: During much of the 1970's, the US Minuteman nuclear ICBM missiles had their launch authorization codes set to "00000000" (without the knowledge of the President or Secretary of Defense) and that "everyone" at Strategic Air Command knew the "secret" password. According to the author, a former nuclear weapons officer:
The Strategic Air Command (SAC) in Omaha quietly decided to set the "locks" to all zeros in order to circumvent this safeguard. During the early to mid-1970s, during my stint as a Minuteman launch officer, they still had not been changed. Our launch checklist in fact instructed us, the firing crew, to double-check the locking panel in our underground launch bunker to ensure that no digits other than zero had been inadvertently dialed into the panel.The locks were eventually activated in 1977. (Via Slashdot.)
SAC remained far less concerned about unauthorized launches than about the potential of these safeguards to interfere with the implementation of wartime launch orders. And so the "secret unlock code" during the height of the nuclear crises of the Cold War remained constant at 00000000.
A student who has been expelled from his degree program for internet plagiarism is suing the university for having caught him too late. He claims that the school "should have spotted what he was doing and stopped him sooner."
According to this article, his argument is as follows:
According to this article, his argument is as follows:
It's a technique I've used since I started the course and I never dreamt it was a problem. I can see there is evidence that I have gone against the rules, but they've taken my money for three years and pulled me up the day before I finished. If they had pulled me up with my first essay, and warned me of the problems, it would be fair enough. But all my essays were handed back with good marks and no one spotted it.

Invention of the day: A roll-up flexible piano keyboard. On Star Trek: Next Generation, there was an episode "Lessons" in which Nella Daren played a duet on a similar-looking (fictional) instrument with Captain Picard on the Ressikan flute.

Google's IPO could be a huge windfall for the company's early financial backers. Those initial investors could receive up to $150 - $400 for each $1 they put in.
