Finding a missing piece for neurodegenerative disease research
Ursula Jakob and a team at the University of Michigan have found that the molecule polyphosphate could be what scientists call the 鈥渕ystery density鈥� inside fibrils associated with Alzheimer鈥檚, Parkinson鈥檚 and related conditions.
What I鈥檝e learned about water, aging and protein quality control
Alice Liu thought an increase in heat shock protein chaperones would prevent misfolding in Huntington鈥檚 disease proteins. The results surprised her, and water was the key.
Helping mitochondria run smoothly may protect against Parkinson鈥檚 disease
As the powerhouse of the cell, mitochondria lie at the intersection of many essential biochemical pathways. When they go awry, neurodegenerative diseases can result.
Scientists discover brain circuits for placebo effect pain relief
A new pain control pathway from the cortex to the cerebellum is crucial when the expectation of relief leads to pain alleviation without a therapeutic intervention.
Mapping out the protein path to hearing
To determine the profile of inner hair cell proteins, a team of researchers develops a technique that optimizes proteomics for limited sample sizes.
