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.
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.
It's life, but not as we know it. Researchers in the Netherlands have found that a microbe from deep beneath the ocean can breathe a major ingredient in rocket fuel. The discovery suggests that early life may have used many different kinds of chemicals besides oxygen to survive and thrive.
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.
Amber Bartlett was waiting last Friday for her kids to come home from school. One of them called from the entrance to the upscale subdivision near Little Rock, Ark., to tell her the community was being evacuated because of an oil spill. Bartlett was amazed by what she saw out her front door.
"I mean, just rolling oil. I mean, it was like a river," she says. "It had little waves in it."
