Ian Affleck 1952-2024. Ian was my office mate, tennis partner, and good friend when we were Harvard graduate students. We were particle theorists then, but Ian is best remembered for his many deep contributions to quantum condensed matter. A great loss.

Today makes three years since the fall of Afghanistan and the Taliban’s return.

That’s 1063 days since girls were banned from school. And 969 days since they closed universities to women.

And nobody cares.

Yesterday marked 3000 days of Ahmadreza’s arbitrary detention in Iran, and together with outside of the Swedish consulate in Brussels, we sent a clear message: it is time to bring Ahmadreza home.
3000 days have passed, no more excuses!

[Vida Mehrannia @VMehrannia]

Ahmadreza has agreed to stop his hunger strike, today, after 8 days. He knows that his body could not stand this hunger strike any longer given two past hunger strikes. He is still very tired of this situation and wants his voice to be heard.

[Vida Mehrannia @VMehrannia]

Ahmadreza has a resting pulse of 40 bpm and a systolic blood pressure ranging between 53 and 89. These are life threatening numbers. Do you really care how @Free_Djalali is suffering?

Ahmadreza, is going on hunger strike starting June 26th. He has already endured nearly 3000 days of unimaginable torment in the notorious Evin Prison. Ahmadreza knows that his fragile physical state makes a hunger strike potentially fatal,but he sees no other option.

How many academic papers are written with the help of ChatGPT? To answer this question, we analyzed 14mln PubMed abstracts from 2010 to 2024 and looked for excess words:

Mr. Prime Minister, this is Ahmadreza Djalali. I talk to you from Evin prison, inside a horrible cave where I have spent 8 years , 2 months, almost 3,000 days of my life. Over this period of time, everyday I think if it’s the last day of my life. I & my family are on the same earth but faraway & in 2 different worlds. They are heartbroken, fearful, & full of sadness. I am full of worriness about them.
Mr. Prime Minister, you decided to leave me behind under huge risk of being executed in Evin. You left me helpless. Why not me after 3000 days?

**New DataViz Project**

Curious about academic impact? Tired of rankings? Today we are introducing Rankless (https://t.co/FCy11731uy) a new data exploration platform that can help you explore the academic impact of thousands of universities. All universities produce impact that is specific to certain topics and geographies, but rankings flatten that information. Rankless wants to change that.

Consider a comparison between the University of Utah and the University of Vienna, two universities ranked similarly in the Shanghai ranking. These universities differ in their geographical and topical footprint. The University of Utah specializes in Neuroscience and Medicine whereas the University of Vienna specializes in Physics, Astronomy, and Environmental Sciences. Their geographic impact is also quite different. Utah receives a large fraction of citations from medical centers in the U.S., Canada, and Israel, whereas Vienna receives many citations from technical institutes in Austria, Germany, and Hungary. These differences are easy to explore in Rankless but hard to see in rankings.

Rankless was developed by a talented team at the Center for Collective Learning at Corvinus University (@uni_corvinus). It was brought to life by Endre Mark Borza (@endremborza), a Hungarian economist and data engineer at CCL with the help of Máté Barkóczi, a Hungarian designer form MOME, and Veronika Hamar executive director at CCL.

By moving beyond rankings, Rankless offers a fresh perspective on how universities influence each geography and topic, emphasizing diverse forms of impact and providing a richer understanding of academic influence.
