Research traces the evolution of a gene variant that reduces the risk of Alzheimer’s disease, finding that it originally evolved in response to infectious bacteria.
Researchers made the find using an algorithm that purportedly distinguishes between mutations that were selected for and those that came along for the ride by coincidence, a feat that has long eluded scientists.

Haydeh Payami helped uncover the genetic basis of Parkinson’s disease. Now, she hopes to find new ways to treat the disease by studying the gut microbiome.
A new study shows that the brains of Alzheimer’s disease patients have a greater viral load, while another study in mice shows infection leads to amyloid-β build up.
