Are stick insects unique in their ability to transition to parthenogenesis?
Our new review in @journal-evo.bsky.social covers intraspecific and hybrid origins, cytological mechanisms, and co-occurence of female-only and sexual populations, with comparisons to other taxa.

Muting a Black woman to claim the vote was unanimous is so incredibly on the nose
The White House claims the vote to rename the Kennedy Center was “unanimous.” That is false. I was muted on the call and denied the opportunity to speak or register my opposition. That is not consensus. That is censorship.

- POs down ~ 40% (DRP, most rotators not renewed, retirements)

I personally love the boxes they gave us for packing.
