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.
Studies The Scientist covered this year illustrate the expanding importance of genetic and genomic research in all aspects of life science, from ecology to medicine.
