My experience with #America.gov so far. @IRS has asked me by mail to call them. I have tried more than 10 times and put on hold for more than 2 hours twice then told to call back. @America.gov

We are hiring professors (all ranks) in biophysical or physical chemistry, chemical biology, organic chemistry, and chemistry related to energy sciences, starting 7/1/27. Learn more and apply at chem.yale.edu/about/job-open…. Please share.

In case anyone is wondering why science funding is under attack. There will be longterm fallout from the mismanagement of COVID. No legitimate scientist would say "Follow the science". We're hopefully doing the best we can - there have been many advances and mistakes and there will be more of both.

Hello from the Gordon Conference on Computational Chemistry in Barcelona #GCCC @GordonConf @UCSD @Yale

Wonderful time last week at the Houk Research Symposium at @upitt Lots of great talks and good company!

🎁A great chemist has left us: Yitzhak Apeloig @YitzhakApeloig passed away on May 28. Born in Bukhara, Uzbekistan—his parents were Polish Jews who had fled their home when the Germans invaded Poland in 1939—he came to Israel with his family in 1947. He studied chemistry and physics at the Hebrew Univ. of Jerusalem and obtained a PhD in chemistry in 1974 working with Zvi Rappoport. He continued research in #PhysicalOrganicChemistry as a postdoc with the legendary Paul von Rague Schleyer @LMU_Muenchen and @Princeton Univ. There he became familiar with #ComputationalChemistry that he continued when he started his independent career at the Technion—Israel Institute of Technology @TechnionLive in 1976. He has been loyal to this eminent place until today and even served as its President from 2001 until 2009. Apeloig’s experimental and theoretical studies of #ReactiveIntermediates, #StrainedMolecules, and #organosilicon species are masterpieces and results have become textbook knowledge. Among the many honors he received were the ICS Gold Medal, the Japan Society for the Promotion of Science Award, the Wacker Silicone Award, and ACS Frederic Stanley Kipping Award in Silicon Chemistry. He was a member of Academia Europaea, and he received an Honorary Doctorate from Technische Universität Berlin.

Final program of ISQBP2026, a major event in Computational (Bio)Chemistry, June 15-18 in Cluj-Napoca. Award winners are @orozco_lab and @zoecournia COURNIA for their immense contributions to the field. A fanstatic list of speakers. Registrations still on. isqbp2026.com

LAST CHANCE to register for the 2026 ISQBP President's meeting in Cluj-Napoca, the heart of Transylvannia. This meeting brings together leaders in the computational (bio)chemistry. Still want/need to submit an abstract for a poster? Drop a short email. isqbp2026.com

Very sad that Ken Wiberg passed yesterday at age 98. He was a wonderful scientist, colleague and leader in physical organic chemistry. His theory-driven synthesis of [1.1.1]propellane is a classic and inspiration for the use of strain in many contexts.

Congratulations to my graduate advisor Dennis Liotta. Today 90% of all HIV positive patients have taken a drug that he co-invented. To quote Churchill, rarely have so many owed so much to so few, and I cannot think of a better example than Dennis who exemplifies than quote. news.emory.edu/stories/2026/…
