I (and pretty much everyone in biomedical research) would love nothing more if we never had use another animal in our experiments. But our ability to model organ-level biology is nowhere close to that.

NIH's Aug 2026 proposal would scrap exact scores and percentiles for three broad bins (top = top 25%). With funding rates at 5% or lower, too much then rides on administrative discretion. It devalues peer review and is a deterrent to engage. Tell NIH before Oct 13. grants.nih.gov/grants/guide...

“It could take at least a year for OMB to respond to the comments and amend the draft rule”. Friends, this is a direct result of our collective action. The OMB Rule that would require political review of grants has prompted at least 50K comments. Thanks to all who commented, and you still can.

NIH funded peeps: This is insane and coming for us.
For FY 2026 RPPRs:
If there are any publications with a foreign co-author, a statement submitted through the Signing Official (SO) confirming the author will no longer publish or collaborate with the foreign partner is sufficient to show the collaboration has ended. Also indicate that no IDeA money was transferred via subcontract to an institution in a foreign country. This path will minimize delays.For FY2027 RPPRs onward:
Pls are required to submit prior approval requests for any publication co-authored with individual(s) affiliated with a foreign institution(s).
Per NOT-OD-26-026, prior approval requests must be initiated and submitted by a SO for the recipient organization.
In addition to noting the foreign site and the name of the foreign investigator, the prior approval request should provide information about the nature of the research being conducted; why the involvement of the foreign site is necessary; and whether any data will be transferred.

Three panel comic. Panel 1: a girl sitting across from someone at a table in a restaurant. There’s a basket of some fried food and a glass of wine on the table. The girl, looking off, says “ever since your head got swapped with a viperfish—“ Panel 2: she continues, “it’s like… you’re a totally different person.” The girls expression is one of quiet pain. Panel 3: a guy with a viperfish for a head is sitting across from her at the table. He points to the food between them and asks, “were you gonna eat that last calamari?”

If we want to motivate voters of all ages, we have to try something different. I propose kindness, authenticity, and unapologetic progressivism. People power over entrenched power. That’s the future.
USA TODAY STORY: 

Kat Abughazaleh is speaking to Gen Z. Democrats should listen. | Opinion

What I hope Democrats glean from Kat Abughazaleh's campaign, regardless of whether she wins, is that Gen Z is not content being fed the same talking points Democrats have been making since 2016.

By Sara Pequeño USA TODAY
Updated March 16, 2026, 11:29 a.m. ET

Photo of Democratic congressional candidate Kat Abughazaleh addresses supporters in Chicago after pleading not guilty Nov. 12, 2025, to charges filed in connection with a protest against the Trump administration's mass deportation campaign. Michael Lori/USA TODAYDuring a February debate hosted by Fox 32 Chicago, Kat Abughazaleh said everything I've seen my friends say on Instagram in the past two years.

And there was no skirting around sensitive subjects during her answers. The candidate running for Illinois' gth Congressional District in the U.S. House called for the abolition of Immigration and Customs Enforcement (ICE). Abughazaleh called the actions of Israel a "genocide" and labeled Israeli Prime Minister Benjamin Netanyahu a "war criminal." She brought up concerns about artificial intelligence and plugged her campaign office, which doubles as a mutual aid hub to help constituents in need.

The former journalist and content creator had several moments where she looked directly into the camera and talked to viewers directly - at one point even pulling a brief "Office"-style glance at the camera while her opponents, Evanston Mayor Daniel Biss and state Sen. Laura Fine, bickered over the involvement of the American Israel Public Affairs Committee (AIPAC) in the Democratic race.

Yet throughout everything, Abughazaleh's values shine through.

Her campaign office's mutual aid hub has served thousands in the community and is proving to Democrats that there are things they could be doing now to help their communities. She has been admonished by Democratic politicos who feel her campaign is radical, yet the same people want to see the party capture authenticity like hers.

Photo of Kat, main headshot."So much of our campaign has been experimental and honestly laughed at by a lot of people who have been in politics for a long time," Abughazaleh said. "And then they see that it works, and then they get mad."

They get more than mad - they get scared. They're scared of losing power, and they're scared that someone with no political experience but the values they're scared to espouse is getting so much attention for being what the Democratic Party has been scared to be.

"It's been almost a year now, and this campaign has been run by the hard work and faith of so many incredible people from our staff to our volunteers, and the entire time we have been told that we have no chance, that we have no shot, that this could never work," Abughazaleh said. "And now organizations like AIPAC are panicking because they realize that we're going to win. And we knew the entire time."

What I hope Democratic leaders glean from Abughazaleh's campaign for U.S. Congress, regardless of whether she wins, is that Gen Z is not content being fed the same talking points Democrats have been making since 2016. We want to see the party take charge and do everything in its power to help people. And if we don't get it from those now in office, we will happily run to replace them.

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.

Auschwitz was at the end of a process. We must remember that it did not start from gas chambers. This hatred gradually developed: from ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder. Auschwitz took time.
A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.
