Reductive stress linked to heart disease
...rone, normally helps long strips of other proteins fold
inside cells. When it works properly, the cell produces the correct amount of reduced glutathione, which is healthy for the body. Unfortunately, when the gene that makes alpha B-Crystallin is mutated in humans, the protein unfolds improperly into agg...
Researchers link metal ions to neurodegenerative disease
..."Amyloid is made of proteins and proteins normally fold
into beautiful structures. However, for whatever reason, some misfold and the resulting misfolded structures are also beautiful, but sticky. They stick to themselves and then propagate to form fibrils, but only some of the fibrils turn out to be toxi...

Study of NYC transit system noise levels finds daily rides can result in hearing loss
...re of decibels means that every 10 dBA equals a 10 fold
increase in intensity. Thus a 90 dBA sound is 10 times as intense as an 80 dBA sound. "Several factors have the potential to contribute to hearing loss, including years of ridership, frequency of ridership, and length of rides," observes Dr. Gers...

Nanoscale study gives new insight into heat transfer in biological systems
.... In water-based solutions, proteins instinctively fold
into unique three-dimensional structures, which do much of the work in the body. Misfolded proteins also are implicated in diseases such as Alzheimer's and Parkinson's, and the ability of proteins to function depends on how much they can vibrate in t...
