Don't trust the CDC while RFK Jr. is in charge The HHS secretary, a notorious anti-vaxxer, is now posting his crank views on CDC's website

I can't stay quiet about what RFK jr is doing to the CDC and FDA:

One concern with using ChatGPT for scientific writing is that I find the process of writing itself can influence the final product. Having to articulate something precisely on paper may cause you to rethink your underlying assumptions and conclusions. I think this is particularly true for trainees.

I signed. If you dislike what the Trump administration is doing to NIH and science, you should too.

I have signed this open letter

Donald Trump, RFK Jr, Jay Bhattacharya, Marty Makary, Vinay Prasad, Tracy Beth Høeg & the rest of the GOP science leadership is working hard & fast to dismantle the US biomedical enterprise & celebrating the destruction

Science is under siege from this kooky crowd

Harvard today, your institution tomorrow.

It's all part of the Project 2025 plan to destroy high education in America.

All leading US universities depend on federal funding and tuition dollars from international students. They severely curtailed the former. Now they're eliminating the latter.

Northwestern has not received any NIH funds since March. No written communication about why or what can be done. Thank you Ben Singer for raising awareness at #ATS2025

WHI Funding Announcement (April 21, 2025) Today, Women’s Health Initiative (WHI) investigators were informed that the Department of Health and Human Services (HHS) will terminate WHI Regional Center (RC) contracts at the end of their current fiscal year (September 2025). The WHI Clinical Coordinating Center (CCC) will continue operations until January 2026, after which time its funding remains uncertain. While written notification has yet to be received, investigators have been advised to expect formal confirmation soon.

This is an enormous loss: www.whi.org/md/news/whi-...

‘One of the darkest days’: NIH purges agency leadership amid mass layoffs In shock move, four institute directors at the US biomedical agency are removed from their posts.

Keep big data in the fight against chronic diseases Cuts to NIH funding for biostatistical research would erode the United States' competitive edge, hindering the health, economy, and overall security of the nation
