“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

Whoa! According to Jason Furman the only US industry to grow this year has been data centers & IT
This seems significant.
"U.S. GDP growth in the first half of 2025 was almost entirely driven by investment in data centers and information processing technology, according to Harvard economist Jason Furman."

Without data centers, GDP growth was 0.1% in the first half of 2025, Harvard economist says | Fortune

Electrification could now reach 75% of all energy demand, as the road-transport and heating sectors rapidly electrify 🔥🚗
These two sectors account for 50% of global energy use and are now ready to switch from fossil molecules to clean electrons.

Cornell's agreement actually explicitly restored academic freedom but it allows gov access to anonymized admission data (but not set the criteria).
Now would be a great time to stop legacy admission practices across the ivies and other top private universities.

Finland has a goal to be net zero GHG emissions by 2035.
Emissions were declining, the LULUCF removals were strong, the plan was looking good, but then LULUCF collapsed.
Net GHG emissions have actually risen over the last decade!

My new paper with Cunningham, Hodgson, and Wang (on the JM!) studies the 2017 FDA Final Rule, which required drug firms to publicly disclose all clinical trial results.
Disclosure increased, but innovation slowed.
