Like a Transformer? Protein Unfolds and Refolds for New Function
July 19, 2012 — New research has shown that a protein does something that scientists once thought impossible: It unfolds itself and refolds into a completely new shape. When it refolds, it acquires a new function ... > full story -
'Mad Cow Disease' in Cattle Can Spread Widely in Autonomic Nervous System Before Detectable in the Central Nervous System
July 9, 2012 — Bovine spongiform encephalopathy (BSE, or "mad cow disease") is a fatal disease in cattle that causes portions of the brain to turn sponge-like. This transmissible disease is caused by the ... > full story -
Key to Controlling Toxicity of Huntington's Disease Protein May Be Cell Contents
June 6, 2012 — New research proposes novel therapeutic targets for treating Huntington’s disease. A new study found the toxic effects of the huntingtin protein on cells may not be driven exclusively by the ... > full story -
Prions in the Brain Eliminated by Homing Molecules
April 24, 2012 — Toxic prions in the brain can be detected with self-illuminating polymers. The originators, at Linköping University in Sweden, has now shown that the same molecules can also render the prions ... > full story -
New Yeast Prion Helps Cells Survive
April 23, 2012 — One of the greatest mysterious in cellular biology has been given a new twist. Researchers now show that prions, proteins that transmit heritable information without DNA or RNA, can contribute to ... > full story -
New MRI Technique May Predict Progress of Dementias
April 10, 2012 — A new technique for analyzing brain images offers the possibility of using magnetic resonance imaging to predict the rate of progression and physical path of many degenerative brain diseases, report ... > full story -
Prions Play Powerful Role in the Survival and Evolution of Wild Yeast Strains
February 15, 2012 — Scientists have tested nearly 700 wild yeast strains isolated from diverse environments for the presence of known and unknown prion elements, finding them in one third of all strains. All the prions ... > full story -
Most Lethal Known Species of Prion Protein Identified
February 9, 2012 — Scientists have identified a single prion protein that causes neuronal death similar to that seen in "mad cow" disease, but is at least 10 times more lethal than larger prion ... > full story -
New Findings About the Prion Protein and Its Interaction With the Immune System
December 29, 2011 — Scrapie is a neurodegenerative disease which can function as a model for other diseases caused by an accumulation of proteins resulting in tissue malformations (proteinpathies), such as Alzheimer's ... > full story -
Using Photons to Manage Data
October 27, 2011 — Managing light to carry computer data, such as text, audio and video, is possible today with laser light beams that are guided along a fiber-optic cable. These waves consist of countless billions of ... > full story
