The severe neurodegeneration associated with HuntingtonÕs disease may result from molecular mutations that block the transport of nutrients within cells. Findings from the Emory University School of Medicine indicate that the mutant huntingtin protein limits the efforts of the huntingtin-associated protein-1 (HAP1) to provide nutrients to growing neurons, or neurites. Without those nutrients, neurites fail to develop and mature neurons degenerate.
Huntingtons disease was first identified more than 125 years ago, and often inhibits speech, movement, reasoning and memory. The result of an abnormal Huntington gene, the hereditary disorder is estimated to affect one out of every 10,000 people. Though some current pharmacological treatments do address symptoms, scientists have been unable to stop the diseases progression.
However, scientists at Emory are making headway in the search for a cure. The findings that appear in the May 31 issue of the Journal of Neuroscience are the latest of more than a decade of Huntingtons disease-related discoveries led by Xiao-Jiang Li, PhD, professor of human genetics at Emory University School of Medicine.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
