PHYS.ORG Beta-amyloid peptides, protein fragments that form naturally in the brain and clump into plaques in Alzheimer's disease patients, are thought to be responsible for neuron death, but it hasn't been clear how the substances kill cells. Now, a Purdue University scientist has shown through computer simulations that beta-amyloid may accumulate to kill neural cells by boring holes into them. 4 weeks
