"Now What?" by John J Hopfield is a beautiful read for researchers at all career stages, and especially so for those who wish not to simply solve problems, but rather identify and solve a PROBLEM -- a kind of the deepest question.

Solar capacity is expected to triple based on new projects in the pipeline.
Total global solar capacity, including all projects in construction and planned, is expected to reach almost 3 terawatts, with 80% concentrated in just 15 countries.

👋New preprint: "Interplay of Redox Non-Innocence and Symmetry Breaking in a 4d Coordination Framework"
🧪We’ve made Mo(pyz)₂I₂, the 4d cousin of the Cr(pyz)₂X₂ family — with redox-active ligands, symmetry breaking, semiconducting transport, and very strong magnetic interactions.

So much software reuse is untracked as people cite the software in the SI or because there are upper limits to citations.

Most journals now accept format-free submission (and the others should). Another example of “using AI” to solve a problem that could easily be solved another way?
Finally, someone has solved a real problem with AI! No more having to take a paper in the format for a journal that rejected you, and reformat it for a new journal. Well done!! formatmypaper.com
