Today in @science.org, @mikusp.bsky.social reports a method to replace the C2 of pyridines with N, affording pyridazines.

The change from electronically consonant (pyridine) to dissonant (pyridazine) opens retrosyntheses not typically available to the latter.

Unfortunately he is a less than excellent mayor. He inherited a lot of problems but he hasn't exactly done anything to address them either. Look at the fiasco with the CPS school board for example.

Six of the nine Nobel Prize winners this year work in the U.S.
Three of the six were born outside the U.S., which is the pattern most years. No country has benefited more from welcoming immigrants from around the world.

I think the R01 is basically a non-starter at NIGMS now. Data from NIH Reporter for new and competing awards, comparing number of R01s issued relative to R35s (MIRA). This has major ramifications for basic science and basic science investigators that are not yet in the MIRA pool
Graph showing total R35+R01 awards issued by NIGMS from 2020 to 2025. R01 in black showing a steep decline. R35 showing an increase. Total awards in 2025 slightly up from 2024 but these years are lower than 2020-2023

A lot of people think that every international student admitted means one fewer spot for domestic students, when the opposite is more likely true - the tuition revenue international students bring allows public universities to provide substantial discounts to domestic students, improving access.

Executive orders cannot supersede federal law or the constitution. Federal law sets visa fees, including for H-1B visas. And the maximum fee is $4,500, according to the
Consolidated Appropriations Act of 2016 (Public Law 114-113).

Immigrants, particularly on H1Bs, are the lifeblood of American innovation. If you wanted to hurt US competitiveness in the next century, I can think of few more effective ways than a move like this

Even when found illegal, the mere intent will have irreparably harmed our future
