Attn MRI enthusiasts! 📣

Just in time for Thanksgiving, I’m thankful to share this opportunity to join us as MRI Center Director! ✨ Couldn’t speak more highly of my time here so far—such a supportive & collaborative place to build a lab—and I’m more than happy to share more with anyone interested

The numbers vary from study to study but hundreds of thousands of people have died because of Elon Musk and Marco Rubio illegally disbanding USAID — a body count on par with the first eight years of the Syrian civil war — In just seven months. It’s mass death that is simply unfathomable in scale.

New notices of #NIH awards now have language allowing grants to be terminated if they no longer “align” with agency “priorities”. This will create uncertainty b/c we can’t count on funding if it can be arbitrarily terminated while a study is in progress.

Lots going on but don’t lose track of the Trump attacks on biomedical research and cancer cures.

@jeremymberg.bsky.social posted a leaked #NIH memo today. I want to highlight a few scary parts.

They’re about taking power from scientists and experts and giving it to the president’s hacks. 1/ 🧪
DRAFT/PRE-DECISIONAL - FOR ICD INPUT, 08.15.25 Achieving NIH's Mission: Leveraging Funding Policies Vision: A consistent and unified NIH-wide approach for funding the most meritorious science, addressing health priorities, and supporting a robust biomedical workforce Purpose: This framework provides a rubric by which ICO funding strategies are to be developed, implemented, and evaluated to achieve NIH's goals. All ICDs, in collaboration with their ICO staff, should review this framework and if needed, adjust respective funding policies and pay plan development processes. Background: All ICOs have funding policies to support the mission of NIH to seek fundamental knowledge about the nature and behavior of living systems and the application of that knowledge to enhance health, lengthen life, and reduce illness and disability. Appropriately, ICOs have their own respective, yet complementary, strategic plans to meet their individual ICO missions. It is crucial that there is coordination across ICO strategic plans and resulting funding policies to collectively leverage NIH's successes for the good of the American public. Core Tenets of ICO Funding Policies: Certain core tenets of funding policies should be consistent to ensure that the NIH mission and health priorities are being achieved. Moving forward, ICO funding policies should: • Align with NIH's and the ICO's stated mission and strategic priorities • Prioritize scientific merit, program relevance and program balance • Incorporate the breadth of the ICO's research portfolio and approaches • Consider investigator career stage and sustainability of the biomedical research workforce • Consider the total amount of NIH funding available to the investigator to promote distribution of funding • Align with the availability of funds from the ICO Note that while the score and critiques an application receives in peer review are important factors in determining the scientific merit of a proposal, ICOs may not rely on funding "…

How awful. This is outright health disinformation, lying to the American people. Not only is there massive evidence showing no link between vaccines & autism, there’s not even a plausible mechanism based on what we’ve learned about the genetics of autism, some environmental exposures in pregnancy
sherylnyt.bsky.social Sheryl Gay Stolberg @sherylnyt.bsky.social · 6d
HEADS UP: CDC website now officially asserts that vaccines may cause autism.“Studies supporting a link have been ignored by health authorities.” Also says the “vaccines do not cause autism” header remains b/c of an agreement with Cassidy.
