🧪Totally disingenuous. The question is not whether the speakers you chose are popular or unpopular. The question is whether or not they are qualified. And an administrator cutting science for political purposes and suppressing scientific studies is not "advocating for scientific reforms".

“It was Barry who discovered that lymphocytes-not macrophages, as some hypothesized-that carry immune memory. showed that lymphocytes signal to macrophages through a chemical they termed MIF-which, together w/ interferon, were the 1st cytokines discovered” www.statnews.com/2026/03/30/b...

Remembering public health pioneer Barry Bloom: a scientist, a mentor, a mensch

Marc Lipsitch and Yonatan Grad pay tribute to their former colleague and mentor Barry R. Bloom.

The data is in: the NIH goalposts have shifted. What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards. Another manifestation of how HHS policies have led to fewer awards and less science.

Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success.

We found that while close contact contributed to elevated risk (rate ratio 1.16 per doubling daily time, 95%-CI 1.01–1.33), time spent in shared classrooms and poor air quality had larger effects (RR 3.17, 95%-CI 1.96–5.17 and RR 1.90 95%-CI 1.23–2.94) respectively).

This is a targeted attack on science media. Bhattacharya has slammed science media for what he calls biased coverage, but how are our readers — the global scientific community — supposed to understand his new agency priorities if we can't even get in the door?

Just spoke to The Hill about how the dismantling of the NIH is impacting science in America. We still face a cliff of unfathomable heights, w easily 1000+ labs poised to close in the next year due to funding ending. A generation of young scientists lost because there is nowhere for them to train.

A bad thing is unfolding at NIH this week: It looks like the Trump administration is trying to replace key civil servant scientific leaders, the Institute Directors, with political hires. These directors control the NIH budget, tens of billions. A bit of a video explainer here: 1/ 🧪

Immigrants, particularly on H1Bs, are the lifeblood of American innovation. If you wanted to hurt US competitiveness in the next century, I can think of few more effective ways than a move like this Even when found illegal, the mere intent will have irreparably harmed our future

But it does not *want* to do that. It has the personality and confidence of a 10x coder, and *absolutely lies to your face* to maintain the illusion. It races to establish huge frameworks, call up parallel agents, and build you something that gives an output.

How bad will it be? Catastrophic. Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come. But, this is the WH's *proposed* budget. Speak up now before it is too late. (inflation adjusted $-s below)

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

A not very happy Friday. CERI had 6 NIH grants canceled, which will impact operations, surveillance and response to epidemics. We are working to try to minimize disturbance but not easy with 6 grants terminated at the same moment. A crisis is unfolding in SA www.news24.com/southafrica/...

SA universities face funding crisis as US federal agencies freeze research grants | News24

An investigation into the impact of the US aid freeze on research funding to South African universities has found that 44 programmes worth R2.5 billion were affected.

I received a surprising and disturbing request from NIH on Friday. They wrote to cancel a subaward to Hong Kong on one of my grants. (This was disturbing but not surprising.) They also ordered us not to interact with our collaborators in Hong Kong on any work under the award:

Screenshot of email stating "The subaward and the associated amounts listed above will need to be removed from the current and future year awards, and any other amounts budgeted for activities related to the Hong Kong research must also be removed. No rebudgeting of these funds is permitted, and no involvement or collaboration with researchers in Hong Kong or China is permitted in connection with the activities of this award, regardless of whether any funds are transferred," with the "no involvement" clause highlighted.
