Harvard Is Said to Be Open to Spending Up to $500 Million to Resolve Trump Dispute

There is a deep problem with Michael Bender, Alan Blinder & Michael Schmidt's article. This isn't a dispute or Harvard making a deal. As many have said this is extortion as in "nice university you have there, would be a shame if something happened to it." 1/ www.nytimes.com/2025/07/28/u...

Following up to this, I built a full basic working example for molecular DFT calculations running totally in the browser: www.prs.wiki/utilities/wa... - it's pretty neat to be able to run an SCF on your phone, and web assembly is really surprisingly fast! Visualising orbitals next!

Columbia Agrees to $200 Million Fine to Settle Fight With Trump

Surely this will be the payment that finally gets the extortionist to stop demanding money

Congressional Event: A Science Fair of Canceled Grants The Things We’ll Never Know: A Science Fair of Canceled Grants.

A science fair of cancelled grants. The research that will be represented at this event (Tuesday) ranges from neuroscience, to astrophysics, to STEM education. The awarding agencies of the now-canceled grants include the EPA, DHS, NIH, NSF, USAID, and DOD. Open to the public.

When I updated to CSD version 6.00, there were some weird issues where not everything got updated in ConQuest. I opened a ticket with support, they had me clear an old file or two, and then it worked as expected. Maybe something like that is happening here.

In the "Select Subset" view. I think it's the same one you're looking at here.

Something looks broken with yours. I get 131682 refcodes in CSD version 6.00.

What I like the most about the UMA (OMol25) model is that it can take spin and charge as the input. This is a game changer as it allows simulating a large vareity of compounds with correct spin multiplicity. Seems to be quite accurate uptil now in my tests.

Glad to hear it! We spent many, many hours discussing how to deal with charge and spin in OMol25...!

Here Is All the Science at Risk in Trump’s Clash With Harvard More than 900 research grants worth $2.6 billion are in jeopardy. So is the 80-year-old model of American science.

How Trump Blew Up Northwestern’s Business Model The federal government froze the university’s research funding. It hasn’t offered the school a way to get it back.

Funding freeze at Northwestern from Emma Mairson at
grant-watch.us. Data from USAspending. Normally, ~$70 M per month. Now, bupkis.

Northwestern is keeping research moving and must be spending ~$40 M per month. Clearly not sustainable for too long.

Opinion | Harvard Derangement Syndrome ​In my 22 years as a Harvard professor, I have not been afraid to bite the hand that feeds me. So I’m hardly an apologist when I say the invective aimed at Harvard has become unhinged.

The concern over antisemitism allegedly motivating the federal defunding of science at Harvard "is patently disingenuous, given Mr. Trump’s sympathy for Holocaust deniers and Hitler fans. The obvious motivation is to cripple civil society institutions,” writes the Harvard professor Steven Pinker.
