Protein usually linked to diseases found guiding genetic material into sperm

Scientists at Columbia's Zuckerman Institute have found amyloid, a kind of protein usually linked to diseases, guiding genetic material into sperm cells. "Amyloids are most often thought of as a hallmark of Alzheimer’s, Parkinson’s and other neurodegenerative diseases in the brain, but they also have functional roles," researcher Anthony Fitzpatrick said. "This is wild biology," he added.
