A fringe theory about the origins of Alzheimer’s disease—that latent viral infections can sometimes trigger its emergence—has gotten perhaps its most significant bit of support yet. A complex new study published Thursday in Neuron has found evidence that certain viruses are not only more common in the brains of people with Alzheimer’s, but that they play a direct role in the chain of events responsible for the fatal neurodegenerative disorder.

Two Ebola patients slipped out of a treatment center this week in the Democratic Republic of Congo, aid agency Doctors Without Borders said, raising fears the virus may spread as health officials raced to trace anyone they may have encountered.
Influenza, SARS, Ebola, HIV, the common cold. All of us are quite familiar with these names. They are viruses—a little bit of genetic material (DNA or RNA) encapsulated in a protein coat. But what we don’t really understand, and what scientists have struggled with since the study of virology began, is whether viruses are actually living or not. A paper published today in Science Advancesjust might change that. By creating a reliable method of studying viruses’ long evolutionary history—hitherto nearly impossible—researchers have found new evidence that strongly suggests viruses are indeed living entities.
There’s been quite a bit of attention focused on the microbiome. Back in 1988, it was defined as the community of all microbial living organisms within a particular habitat. But over the years, the scope of the term has contracted to mean for the most part only bacteria. It’s not really a surprise as most work to understand the microbial environment within each environment, including the human body, has focused on this one branch of the tree of life.
