I'm looking forward to reading this new pre-print from the Van Wolfswinkel Lab at Yale, which fills significant gaps in understanding how systemic RNAi works in planarians.

A new mechanism for “RNA memory”! This time in Planaria! (Here's a video of a Planarian with mulitple heads, one of the heritable phenotypes we studied).

This work summarizes >10 years of research and is an amazing collaboration with the labs of Jochen Rink and Omri Wurtzel labs. Read thrad below👇

Overdue congratulations to Mallory Cathell, who successfully defended her doctoral dissertation back in June!

Since then, she has been hard at work preparing a manuscript based on her thesis.
