We conducted a #ChemNobel prediction poll in the group on the #NobelPrize in Chemistry Eve!

(PS: we might be a little biased 😉) #chemsky #compchem #compchemsky
Bar chart titled “Chemistry Nobel Prize 2025 Prediction Poll.” The chart lists predicted discoveries and scientists, sorted by increasing number of votes. Biomolecular Condensates — Brangwynne, Hyman, Rosen (1 vote) Chemical Biology — Chi-Huey Wong, Stuart Schreiber, Peter Schultz (1 vote) Reticular Chemistry — Omar Yaghi, Makoto Fujita, Richard Robson (2 votes) Controlled Radical Polymerization — Ezio Rizzardo, Krzysztof Matyjaszewski, Mitsuo Sawamoto (2 votes) C–N Coupling — Stephen Buchwald, John Hartwig (2 votes) DNA Synthesis — Marvin Carruthers (2 votes) Electron Transfer — Harry Gray, Jacqueline Barton (2 votes) Next-gen DNA Sequencing — David Klenerman, Shankar Balasubramanian, Jonas Mayer (3 votes) Single-Atom Catalysts — Tao Zhang et al. (4 votes) Ab initio Molecular Dynamics — Roberto Car, Michele Parrinello (6 votes) Ab initio MD received the highest number of votes in the poll.

HOMEWORK MACHINE The Homework Machine, oh the Homework Machine Most perfect contraption that's ever been seen. Just put in your homework, then drop in a dime, Snap on the switch, and in ten seconds' time, Your homework comes out, quick and clean as can be. Here it is — "nine plus four?" and the answer is "three." Three? Oh me ... I guess it's not as perfect As I thought it would be.
