Glad to see a study like this! I feel like we've been wondering about this for years haha The results don't really surprise me...but it'd be a cool to see a version with trait evolution dynamics.

Tip rate estimates can predict future diversification, but are unreliable and context dependent https://www.biorxiv.org/content/10.1101/2025.10.06.680809v1

Oh God, am I in the minority for getting into it in the last 5 years? Cumbersome as hell sometimes, but I've just found it so useful for math typesetting and more "programmatic" formatting/generation of figures, tables, etc.

I am irrationally bothered by "ICE law enforcement". I guess, first off, because it feels like a feeble attempt to further blur the line between ICE and actual police. But also just because "immigration customs and enforcement law enforcement" is like the dumbest thing I've ever heard.

Today, the UN officially designated Israel’s assault on Gaza as a genocide.

As a party to the Genocide Convention, the U.S. has a legal obligation to obey our own laws, stop weapons sales to Israel, and demand a permanent ceasefire.

End the genocide. Ceasefire now.

257. The Commission recommends that all Member States:
(a) Employ all means reasonably available to them to prevent the commission of genocide in the Gaza Strip;
(b) Cease the transfer of arms and other equipment or items, including jet fuel, to the State of Israel or third States where there is reason to suspect their use in military operations that have involved or could involve the commission of genocide;
(c) Ensure individuals and corporations in their territories and within their jurisdiction are not involved in the commission of genocide, aiding and assisting the commission of genocide or incitement to commit genocide and investigate and prosecute those who may be implicated in these crimes under international law;
(d) Facilitate the investigations and domestic proceedings and take action (including imposing sanctions) against the State of Israel and against individuals or corporations that are involved in or facilitating the commission of genocide or incitement to commit genocide;
(e) Cooperate with the investigation of the Office of the Prosecutor of the International Criminal Court.
258. The Commission recommends that the Prosecutor of the International Criminal Court:
(a) Examine, within its continuing investigation in the Situation in the State of Palestine, the crime of genocide for amendment to existing arrest warrants and addition to future application for arrest warrants;
(b) Examine the involvement of officials mentioned in this report for inclusion as those most responsible for international crimes committed in the occupied Palestinian territory.

When I was placed on the Professor Watchlist in 2021, people sent death threats about my children. I had security officers monitor my 8yo at school.

Where is all the outrage for those of us who have been targeted for years? Where is the outrage for our families?

My own colleagues are silent.

The whole nature vs nurture, innate vs acquired framework is so oversimplified and really breaks down under scrutiny, in my opinion. There's so much cultural baggage around these topics that I get why folks might be hesitant to discuss the full nuance of it all, though...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

Analyses of a new genomes for garden asparagus and a Mediterranean basin congener reveal independent origins of dioecy and XY sex chromosomes. The work led by Phil Bentz @pbentz.bsky.social finds no overlap in the two Y-linked sex-determination genes - www.biorxiv.org/content/10.1... .
