October 23, 2012 - Scientists say smoking in the car, even with the windows open or the air conditioning on, creates pollution that exceeds official "safe" limits. according to the Tobacco Control journal, A Scottish team who took measurements during 85 car journeys found readings broke World Health Organization limits. Professor John Britton, of the Royal College of Physicians Tobacco Advisory Group, says a ban is necessary to protect children. He says that estimates suggest each year passive smoking in children accounts for more than 20,000 cases of lower respiratory tract infection, 200 cases of bacterial meningitis, and 40 sudden infant deaths.
Also, researchers at the University of Michigan say it's not all about calories and exercise, and that some people's brains could be causing them to be fat. In a new study, scientists say some people's brains do not respond to a hormone called Leptin that regulates appetite. This causes them to keep eating, and gain weight. The discovery could lead to targeted treatments for obesity.
