This one is special! First lab preprint: From when the competent bacteria were not competent and all the mammalian cells died all the way to a superb biosensor for ERK activity that works in neurons, spheroids, and zebrafish! And all of it by FLIM. Congrats Elias, Rohan, Dennis! tinyurl.com/389xzbtc

Hello bluesky, I'm a theoretical chemist at University of Bayreuth. My group works on atomistic modeling of energy materials with electronic structure methods and ML. I'm hoping to connect to other #compchem and #materials folks!

One of the last papers from my postdoc with @aspuru.bsky.social is now out. Led by the tireless @gkwt.bsky.social, it investigates chirality in text-based generative models. Includes a nice simulation-based benchmark task for circular dichroism that I think could be useful to the community.

One nice aspect of the Nobel Prize that not everyone knows is that they actually publish a short scientific document explaining the contributions of the Prize winners. The one for MOFs can be found below. As such, we can actually do "peer review" of the prizes ๐Ÿง www.nobelprize.org/prizes/chemi...

To me, it is quite mysterious how the seminal contributions of Allinger were passed by. This year, it is gratifying to see that the contributions of Robson have been recognized, even though he is (today) not as well known at the other awardees on the international scene.

One of the areas where I would feel more competent is for the 2013 Prize on multi-scale modeling. I remember these worthy prize winners well, as I had the honor of receiving a prize for my MSc thesis from the hands of Levitt and Warshel when they visited Uppsala www.nobelprize.org/prizes/chemi...

nobelprize.orgNobel Prize in Chemistry 2013The Nobel Prize in Chemistry 2013 was awarded jointly to Martin Karplus, Michael Levitt and Arieh Warshel "for the development of multiscale models for complex chemical systems"

The seminal contribution of Warshel and Karplus from 1972 is listed as the first combination of QM (the PPP method) and MM (a classical force field) for "complex systems". A few years ago, I had the pleasure of myself working with the PPP method and reading the extensive literature on the topic.

Excellent Nobel Prize. My suggestion for next year: chemical engineering. Nobel himself was an engineer, and the prize awards achievements that "conferred the greatest benefit to humankind". Furthermore, the Prize should also be given to "improvements". When did that happen the last time?

Palli Thordarson@palliunsw.bsky.social

Indeed! Great day for Aussie chemistry. Richard Robson's work is finally being properly recognised. Congratulations also to Kitagawa and Yaghi. #ozchem
