Roughly half of STEM PhD students in the U.S. are international students.

75% of them stay in the U.S. long term after graduating to contribute their skills to U.S. scientific research and development.

Cutting international student visas hurts U.S. science now and long into the future.

Hey y'all. Love all the love for the program (we're pretty proud of it too). But the fact that the solicitation is archived does NOT mean that the program is shutting down. We're hanging in there, struggling through the uncertainty with everyone else.

LTER has been archived for about a year now. It’s normal between solicitations. LTER is still here.

Oh no. NSF Long Term Ecological Research (LTER) program shuttered.

The data also reinforce a message that should be clear: American leadership in science and medical research requires far more than getting across the line on top-line budget negotiations and will require continued vigilance to track how HHS treats applications and existing awards.

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.

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.

EPA eliminates research and development office as it begins thousands of layoffs The Environmental Protection Agency said Friday it is eliminating its research and development arm and reducing agency staff by thousands of employees.

A 23% reduction in staff at the EPA and closure of their research program will make it much easier for companies to pollute land, water, and air without being held accountable. This will hurt all of our children and grandchildren. This is very sad to watch. 🧪
