The Truth about Cars and Cell Phones

We find it terrifying every time we get on the highway and see all of those multitasking drivers racing along while they talk and text on cell phones. So it is especially distressing to learn that in 2003, officials at the National Highway Traffic Safety Administration put down a proposal for a large-scale study of cell phone risks and withheld hundreds of pages of research that warned about the dangers of cell phone use while driving.
That information-including estimates that cell phoning drivers caused 955 fatalities and 240,000accidents in 2002--was finally pried loose this week by a freedom of information lawsuit.
Six years later, the Transportation Department advises drivers to avoid cell phones except in emergencies. But far too many Americans now consider phoning while driving to be standard behavior.
Extensive research shows the dangers of distracted driving. Studies say
A. they think only others are dangerous
B. they always have some important information to deliver
C. they may feel bored without talking to someone
D. they need to stay in touch with their friends and colleagues

While it’s true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason. The last thing you want is for your brain cells to start producing stomach acid or your nose to turn into a kidney. The only time ceils truly have the potential to turn into any and all body parts is very early in a pregnancy, when so-called stem cells haven’t begun to specialize.
Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy cells--brain cells in Alzheimer’s, cardiac cells in heart disease, pancreatic cells in diabetes, to name a few. If doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue. It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, muscle and bo
