The Regents have always had ultimate power over hiring and curriculum. Previously they were wise enough to take recommendations from experts in the areas involved. We urge the Regents to continue to rely on the considerable expertise of the university’s world class faculty!

JUNO is taking data only since 2 months, and they have already measured the solar neutrino oscillation parameters theta_12 and Deltam_12^2 with world-leading precision:

Congrats in particular to my ULB colleagues involved!
First measurement of reactor neutrino oscillations at JUNO

UT: please list every one of your publications from the last year. No we do not integrate with ORCID or anything like that

A point I keep trying to make: this, too shall pass, and the people who would sell out their institutions for their careers and resentments will have to live in that environment
This insanity is going to pass (not tomorrow but eventually) and at that point there has to be real accountability for these institutions and decision-makers; at this level, it will likely be social and interpersonal more than anything
"The professor will no longer be able to teach a class on diversity after she showed students a diagram that included the 'Make America Great Again' slogan as an example of white supremacy."

Honestly this feels like the dynamic with the sciences too
Great piece by Zadie Smith. When the right talks about classics or "Western" culture, these works are only important to the extent that it demonstrates their superiority, they have no interest in art in and of itself beyond that www.theguardian.com/commentisfre...

It is a, let's say, interesting fact that "academic integrity" is discussed here primarily not as a question of, say, honesty or disclosure of conflicts but as one of "respect for differences" and "balanced treatment of disputed issues"

Congrats to the authors, I cannot stress how annoying this process is to measure
The production of top quark pairs together with a W boson is a great way to test the quality of standard model predictions. This #CMSPaper measures provides boundaries on things like the difference between ttW+/- production, a very sensitive quantity to test the predictions arxiv.org/abs/2509.13512

The thing about her list of complaints about academia (protests! chronicling Western oppression! research with no practical benefit! the CDC for some reason!) is that they can only be addressed by reducing the scope of things people do in universities, which doesn't sound like "viewpoint diversity"
The definition of “viewpoint diversity” that figures like this promote implies *censorship* (the “must” part): curbing some forms of expression to boost others. It’s an invention of orgs who advocate government censorship of teaching/research + restrictions on protected political speech in colleges.
