Excellent piece in Nature Physics - "American science needs an executive branch constrained by checks and balances" 🧪 Our current problem is a runaway executive branch and it's essential to return control of science to Congress and the people Thanks @andrewleifer.bsky.social et al! rdcu.be/fCDGE

Big picture: community structure of C. elegans connectome and an "effectome" derived from insane stimulation experiments (see shorturl.at/vYEDZ) are poorly aligned (except for pharynx, oddly). Wires ≠ propagation paths. A truly interesting wrinkle in the tapestry of structure-function papers. 2/3

Science is built on public trust, federal funding, and academic freedom. All of these are currently being eroded, but what can we do? Join us for an online panel on "Being a Voice for Science" (June 11, 2-3pm ET). Info and registration: engage.aps.org/dbio/resourc...

New op-ed in @nature.com: The Trump administration's assault on freedoms and the rule of law is an existential threat to US science. We urge scientists to speak out in defense of freedoms, not just funding. With Andrea Liu @upenn.edu and Sidney Nagel of UChicago! www.nature.com/articles/d41...

US researchers must stand up to protect freedoms, not just funding
Curtailment of freedoms and disregard for the rule of law in the United States is destroying the ability of science to serve the nation’s, and the world’s, interests. Researchers can take action.

Those trying to understand the tariffs as economic policy are dangerously naive. No, the tariffs are a tool to collapse our democracy. A means to compel loyalty from every business that will need to petition Trump for relief. 1/ A 🧵 to explain his plan and how we fight back.
