SJ - I’ve just started my 1-year sabbatical in NYC, splitting time between the Flatiron Institute and NYU Economics to explore “econophysiology,” supported by the Simons Foundation Pivot Fellowship. If you’re in the area and would like to connect or interact with me & my lab, feel free to reach out!

Serial innovations by Asgard archaea shaped the DNA replication machinery of the early eukaryotic ancestor - Nature Ecology & Evolution
Phylogenetic and biochemical analyses show a diversity of components of the DNA replication machinery in different Asgard archaea that contributed to the eukaryotic DNA replication machinery.

A show of bipartisan support for NIH. Basically flat except for ARPA-H.
The President’s budget proposal basically ignored (as it should have been).

House LHHC bill is out. Lots of hits to HHS, but the top line number for NIH is 1% decrease, mostly due to cuts ARPA-H. This seems like a huge rejection of the president's budget request.

BREAKING: A federal judge in Massachusetts (the Reagan-appointed William Young) has declared the Trump administration's cuts to NIH grants — ostensibly over Trump's EOs on gender ideology and DEI — are "illegal" and "void." He's ordering many grants restored.

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd.
