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.

Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
