New preprint describing our GNN charge model, AshGC! Since QM methods of charge assignment scale poorly to larger molecules, and are also conformation dependent, AshGC leads to major performance improvements in this critical step in force field parameterization. chemrxiv.org/engage/chemr...

Developing and benchmarking Sage 2.3.0 with the AshGC neural network charge model

We report a new charge model and a new general small molecule force field. Here, we address the development and benchmarking of both the Open Force Field (OpenFF) AshGC charge model, as well as the Sa...

We’re pleased to announce Sage 2.3.0 Release Candidate 2 (rc2)! Sage 2.3.0 will be the first OpenFF force field to use the AshGC neural network charge model, which was trained to AM1BCC ELF10 charges, and allows for rapid charge assignment for molecules with hundreds or thousands of heavy atoms.

@ckohlmeier.bsky.social here at CU Boulder just released a Coursera intro to Python for scientific computing. Different from other intro courses by emphasizing doing engineering calculations, like optimization and numerical integration. 1/2

Journalists keep asking me, baffled, “What’s the Trump administration really trying to do to the science agencies?” So I say “They are trying to destroy them. Cut off their funding, ruin their facilities, harass their staff into leaving.” It’s not reform, and it never was. It’s destruction.

NEW: NSF will be kicked out of their building. Announcement will be made tomorrow by HUD Sec. and Governor of VA. HUD will take over the NSF building over the next two years. NSF staffer: "There is no planning for NSF, no identified future location, appropriation for a new building or a move."

Key thread here. NSF's own projections are that the success rate for competitive awards would drop from 26% to 7%, and the number of students, postdocs, and senior researchers involved in NSF research will drop by ~70% each, ~80% for undergrads. Perfect "Make China Great Again" policy.

I am looking at NSF's budget request, in awe at the disinvestment in learning anything. nsf-gov-resources.nsf.gov/files/00-NSF...

How bad will it be? Catastrophic. Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come. But, this is the WH's *proposed* budget. Speak up now before it is too late. (inflation adjusted $-s below)

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

This is the president's budget request to congress for 2026 for the National Science Foundation. Down 56%. Say goodbye to science as we know it in the US if this is remotely reflected in the final congressional bill. Most of the NSF funding ends up paying for PhD students in science.

Presidential budget is out. Here's NSF. Biggest cut, by amount, is $1 billion, or 66.8%, from MPS (Physics & Math directorate). nsf-gov-resources.nsf.gov/files/00-NSF...

MPS budget

The NSF's flagship fellowship program typically gives offers to 2,000+ young scientists. This year, in the face of looming budget cuts, that number was halved: only 1,000 received an offer. Our story on what that means for the science talent pipeline: www.nature.com/articles/d41...
