The #SCIMaP project has included these terminations as part of our analysis flow, again linking the site of grant terminations to local economic impacts. The scope of grant terminations remain a surprise to many, both to those who oppose and to those who support them.

Amidst a government shutdown in which the White House has proposed slashing federal support of science by billions of dollars, our #SCIMaP team continues to assess the impact of research cuts on communities nationwide.

Without new HHS leadership, we should be concerned that some of the CDC structure & 'brand' will persist, but what the CDC does & says will be largely unrecognizable.
As one example, the MMWR landing page has no new issue but does have a political talking point banner.

I completed a PhD in Physics at MIT in '03. Even when the intensity seemed to be off-scale, there was one piece that I never doubted: the place had integrity, purpose, and passion.
It's clear the culture and drive of MIT remains.
