Industrial cities like Detroit have high levels of lead in the aging housing stock and in soils. Researchers found that the amount of soil lead in Detroit that gets suspended in the air correlated with the levels of lead in kids' blood.
Lead poisoning in kids is hardly the problem it used to be, now that we've stopped using lead in house paints and gasoline. But the lead that lingers outside and in old homes is still dangerous if kids are exposed to it.
This is SCIENCE FRIDAY, I'm Ira Flatow. Earlier this week, the New York Times reported new CDC data on diagnosis of attention deficit hyperactivity disorder, ADHD, in kids. And the numbers are startling, with 11 percent of the parents surveyed reporting a diagnosis of ADHD for their school-age kids, higher numbers for some sub-groups of age and gender. That's a big jump. Estimates before that had been that ADHD affected somewhere from three to seven percent of children.

Reporting in Science Translational Medicine, researchers write that amyloid-forming proteins, traditionally thought of as enemies to the nervous system, may actually be protective 'guardians' instead. Study author Lawrence Steinman, a neurologist at Stanford University, explains how amyloid injections helped paralyzed mice with a multiple-sclerosis-like disease walk again.
A federal judge in Brooklyn, N.Y., has ruled that the morning-after pill for emergency contraception must be made available over the counter to girls 16 and under.
The ruling could end a more than decade-long battle over how easy or difficult it should be for teenage girls to obtain emergency contraception. The ruling would also make it easier for older women to obtain the drug because it wouldn't have to be kept behind drugstore counters anymore.
Scientists say they have found a way to get a glimpse of people's dreams.
"Our results show that we can predict what a person's seeing during dreams," says Yukiyasu Kamitani, a researcher at the ATR Computational Neuroscience Laboratories in Kyoto, Japan.
Philosophers, poets and psychologists have long shared a fascination with dreams. But Jack Gallant, a neuroscientist at the University of California, Berkeley says solving the mystery of our dreams is one tough problem.
