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, <em>Archaeoglobus fulgidus,</em> 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.
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.
