Hello new folks! Thanks for stopping by. Sometimes I post about biochemistry, but it’s mostly cats/classical music/books/things in my garden here. Live from Cornwall. Beardy, generally worn down by academia.

Do we need to rethink the QA quenching model of chlorophyll fluorescence? Probably not, but here's a provocative chin stroker from Győző Garab.

Revisiting the QA model of chlorophyll-a fluorescence induction: new perspectives to monitor the photochemical activity and structural dynamics of photosystem II - Photosynthesis Research
The technique of chlorophyll-a fluorescence induction (ChlF) is widely used in plant biology. The ‘mainstream’, so-called QA model of ChlF, posits that the reaction centers (RCs) of Photosystem-II (PS...

The first (1955) Danish edition of Ray Bradbury’s FAHRENHEIT 451. Later editions did not convert the title, so this is the only SI-compatible edition! 🎢

Once again, EVERY R1 research university depends on federal funding for ~15-25% of its budget. You simply can't unplug the largest or 2nd-largest source of $$ of every R1 university & expect it not to have devastating consequences for graduate education, which will spill over to undergrad education.
Wow. Harvard nuking its PhD programs
- Science PhD admissions reduced by more than 75%
- Arts & Humanities reduced by about 60%
- Social Sciences by 50–70%

Most foreign postdocs working in the US have J1 status, but not all (I was H-1B). H-1B visas in academia are treated differently to those in business, so it's unclear to me if this proposed $100k fee applies (but it will be the absolute death of the program for academics if so).
