This is a genuinely huge, sweeping victory today for the University of California—or rather, for us, its faculty, acting through our faculty associations, while the UC itself maintained a strict policy of deer-in-headlights silence.

NIH, CDC, HHS, and all of US cancer research and public health needed and still needs protection from Russell Vought and the P2025 White House.

The defining feature of 2025 at NIH was not merely grant changes.
It was unprecedented levels of presidential interference with NIH decision-making.

NEW: Another NIH institute director hasn't been renewed — the director of NIAMS (arthritis, musculoskeletal and skin diseases institute).

That leaves a whopping 15 of 27 institutes and centers without a permanent director.

This episode has been a nightmare for my city and state, but I hope people realize it’s also a profound defeat and political catastrophe for Trump and DHS, who are slinking away having accomplished nothing. Minneapolis simply wouldn’t bend to them and they lost

Thrilled that my paper is out in the @nature.com. We explored how the brain builds complex tasks by compositionally combining simpler sub-task representations. The brain flexibly performs multiple tasks by dynamically reusing neural subspaces for sensory inputs and motor actions

My sense of Minnesota today is that there’s less tear gas and the same amount of unlawful detention, destruction of families, loss of livelihood, people in hiding.

There is less tear gas at places like Lake and Lyndale, so it’s not making news.
