Scientists at Northwestern University have designed synthetic molecules that promote neuron growth, a promising development that could lead to the reversal of paralysis due to spinal cord injury. [...]
The innovative scaffold is made up of nanofibers formed by peptide amphiphile molecules. The scientists' key breakthrough was designing the peptide amphiphiles so that when they self-assembled into the scaffold a specific sequence of five amino acids known to promote neuron growth were presented in enormous density on the outer surfaces.
"This was all done by design," said Stupp, who is also director of the University's Institute for Bioengineering and Nanoscience in Advanced Medicine. "By including a specific biological signal on the nanostructure we were able to customize the new materials for neurons."
Morgan Spurlock decided to become a gastronomical guinea pig. His mission: To eat three meals a day for 30 days at McDonald's and document the impact on his health. [...] Within a few days of beginning his drive-through diet, Spurlock, 33, was vomiting out the window of his car, and doctors who examined him were shocked at how rapidly Spurlock's entire body deteriorated.
"It was really crazy - my body basically fell apart over the course of 30 days," Spurlock told The Post.
"Consumers can achieve balance in their daily dining decisions by choosing from our array of quality offerings and range of portion sizes to meet their taste and nutrition goals," McDonald's said in a statement.

OMAHA, Neb. -- Four Westside High School students are suspended for promoting a white student for an African-American award. Flyers featured junior Trevor Richards, a South African native who moved to the United States in 1997.
Trevor said he is as African as anyone else.
