America's Real Criminal Element: Lead 627

2muchcoffeeman writes "The cause of the great increase in violent crime that started in the 1960s and peaked in the 1990s may have been isolated: lead. This leads directly to the reason for the sharp decline in violent crime since then: lead abatement programs and especially the ban of tetraethyl lead as an anti-knock agent in gasoline starting in 1996. There are three reasons why this makes sense. First, the statistics correlate almost perfectly. Second, it holds true worldwide with no exceptions. Every country studied has shown this same strong correlation between leaded gasoline and violent crime rates. Third, the chemistry and neuroscience of lead gives us good reason to believe the connection. Decades of research has shown that lead poisoning causes significant and probably irreversible damage to the brain. Not only does lead degrade cognitive abilities and lower intelligence, it also degrades a person's ability to make decisions by damaging areas of the brain responsible for emotional regulation, impulse control, attention, verbal reasoning, and mental flexibility. Another thing that stands out: if you overlay a map showing areas with higher incidence of violent crime with one showing lead contamination, there's a strikingly high correlation."

Study Compares IQ With Browser Choice 380

rennerik writes "A recent study of 100,000 people taking IQ tests compared the scores with which browser the person uses on a regular basis. On average, Internet Explorer users fared the worst, with IE6 users at the bottom of the pile and IE8 users performing slightly better. Firefox, Chrome and Safari fell in the middle with little difference between them. IE with Chrome Frame and Camino landed on top, along with Opera, whose users scored the highest"

IT Night Shift Workers: Fat and Undersexed 203

wiredmikey writes "The results of a recent survey released today by Men's Health Network found that shift workers, people who work non-traditional hours including IT professionals working overnight shifts, report that these shifts are negatively impacting their health, work, well-being, and quality of life. The survey revealed that the majority of shift workers (79%) believe that they are negatively impacted by their shift work and voiced daily concern over their energy level (47%), weight (43%), and their sex lives (30%). Additionally, the survey showed that the average shift worker hasn't had a meal with their family in two weeks or exercised in 24 days. The results of this survey really shouldn't be surprising. While the survey infers that shift workers may be overweight, the issue extends far beyond and into the general population of the United States, including children. Childhood obesity is at an all time high in America, so this issue isn't just related to the night shift."
