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.
If you're looking for a date on Match.com, does it matter what color your shirt is in your profile picture? Or if you're trying to make a partner, you want to make partner at a law firm, yeah, does having a hard-to-pronounce last name hurt your chances? Does staring at a pile of money, even phony Monopoly money, make you more selfish?
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 bacterium-like microbe, Archaeoglobus fulgidus, seen here in a false-color image, can live in the high temperatures found near deep-sea vents. They can also survive by consuming perchlorate, a chemical used in rocket fuel.
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.

Spilled crude oil is seen in a drainage ditch near evacuated homes near Starlite Road in Mayflower, Ark., on March 31. An Exxon Mobil pipeline carrying Canadian crude oil was shut off after it ruptured March 29, causing an evacuation of 22 homes.
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."
An international team of researchers announced in Switzerland on Wednesday that an experiment on the International Space Station may have seen hints of something called dark matter. The finding could be a milestone in the decades-long search for the universe's missing material.
Only a tiny sliver of stuff in the universe is visible to scientists; the rest is dark matter. Researchers don't know what it is, but they know it's there. Its gravity pulls on the things we can see.
U.S. farmers anticipate planting the most corn since 1936, a total of 97.3 million acres. Farmers are hoping to rebuild their corn supplies after last year's drought. Chad Hart, economics professor at Iowa State University, explains why farmers intend to plant high amount of corn this season.
The Obama administration is delaying the start of a key piece of the Affordable Care Act. Workers in small businesses will have to wait an additional year to be able to choose from more than one plan in the marketplaces that start next January.
