PIWI clade Argonautes are essential for transposon silencing. Without them, animals are sterile due to massive transposon activity.

But how does piRNA-guided target interaction translate into silencing?

PhD student Júlia Portell Montserrat has an intriguing answer

The struggle is real. The struggle is ongoing. Here's to hoping that unionizing can, hopefully someday soon, bring about some needed changes here...
