Here’s what you’ll learn when you read this story:Stanford University researchers have discovered virus-like ‘lifeforms’ that exist inside human mouths and guts. Smaller than a virus and not considered standard life, the genetic material can still transfer information that can be read by a cell. We’re not sure if it’s exciting or not that scientists just discovered new ‘lifeforms’ inside of our bodies. Dubbed ‘wildly weird’ by the team of Stanford scientists in Nature, the discovery now has a name: obelisks. And it isn’t like the Stanford researchers found just one of these things—they located nearly 30,000 distinct types of obelisk.
