New research from the University of North Carolina at Chapel Hill School of Medicine points to the possible molecular origin of at least nine human diseases of nervous system degeneration.
The findings are currently in PLoS Computational Biology, an open-access journal published by the Public Library of Science (PloS) in partnership with the International Society for Computational Biology.
These neurodegenerative diseases, including Huntingtons disease, share an abnormal deposit of proteins inside nerve cells. This deposition of protein results from a kind of genetic stutter within the cells nucleus asking for multiple copies of the amino acid glutamine, a building block of protein structure. These disorders are collectively known as polyglutamine diseases. Along with Huntingtons, these diseases include spinobulbar muscular atrophy; spinocerebellar ataxia types 1, 2, 3, 6, 7 and 17; and dentatorubral-pallidoluysian atrophy, or Haw River Syndrome.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
