Yesterday, our amazing İnönü University partners showcased dynamic nature of liver exchange! We had an O blood-type patient with a O blood-type donor in a planned 3-way exchange. Pre-op calculations suggested graft size was too small for a direct transplant.

The Turkish opposition held a massive rally today in one of Erdoğan’s most loyal strongholds. A farmer nailed it: "You can’t run a country with radish and turnip. You run it with truth, law, and justice." The turnip bit might be a coincidence — but it still lands a little too well in the U.S.

Last year @shengwuli.bsky.social pointed out that the core tenet of my minimalist market design framework—"Don't fix what's not broken"—echoes Chesterton’s Fence (now discussed in Section 2.2.2). In an age of Trumpian & DOGE policies, this tenet feels especially relevant. arxiv.org/pdf/2401.00307

Given the strong parallels between leadership styles of Trump and Erdogan, and the rapid deterioration of democratic institutions in the US, the same headline equally applies to Americam democracy 🙁

Before his arrest on bogus charges, opposition presidential candidate Ekrem İmamoğlu said: “No salvation alone; either all of us together, or none of us.” His words echo far beyond Turkey — a powerful call to unite against authoritarianism.

Erdogan, during his tenure as Mayor of Istanbul in 1990s famously stated “Democracy is like a train: when we reach our destination, we get off.” More than 2 million people gathered today in Istanbul (despite a 9 day holiday) to show Turkish people’s commitment to democracy.
NEW: Today in Instanbul, Turkey.
A people fighting for democracy & against authoritarianism. This is how you do it!
Chairman of Republican People’s Party, Özgür Özel:
“Today, 2.2 million of our citizens overflowed Maltepe Square. This is just the beginning. This nation will not remain silent.” 🇹🇷

For years, I have argued that there should be a penalty for producing non-impactful research, especially in top outlets. Such a mechanism would deter the producing mediocre research, whether generated with or w/o AI. It would also help curb the undue advantage held by gatekeepers in academia.
I used AI to help write a paper and got it published. All in record time. What does this mean for research? My latest post. open.substack.com/pub/joshuaga...
What will AI do to (p)research?
AI makes doing and communicating research much easier. Will there be any point to it?

Opposition from civil society is no doubt important, but it's effective, organized, *unified* political opposition that is needed to reverse the authoritarian slide. That at least is the lesson I draw from (the failures of the opposition parties in) Erdogan's Turkey. Looking at you, Democrats!
