National Institutes of Health faces leadership vacuum as director positions sit open More than half of the NIH's institutes and centers don’t have permanent directors, giving the Trump administration an unusual opportunity to reshape the agency. The latest departure came on Friday.

They won’t stop until the National Institutes of Health is a hollowed out RFK Jr. echo chamber and revenue generation machine for snake oil peddlers.

Trump official overruled FDA scientists to reject Moderna's flu shot FDA's top vaccine regulator, Vinay Prasad, is known for overruling scientists.

Moderna is at least the ninth company to have received a surprise rejection from Vinay Prasad and his team.

A Speech Every Democrat Should Watch Jon Ossoff lays out a message that can work for everyone in the party.

If you were online last weekend, you probably caught some clips from Jon Ossoff’s speech. It’s worth watching the whole thing because it’s an object lesson in how Democrats should communicate in the upcoming midterms. messagebox.substack.com/p/a-speech-e...

Prasad overruled FDA staff to reject Moderna's flu vaccine application The rejection is the latest instance of Vinay Prasad overruling career FDA scientists to place vaccines under harsher scrutiny.

The flu and pneumonia kill over 45,000 people a year. Moderna developed a new mRNA flu vaccine for people 50 and older--who are most at risk. Prasad, unilaterally, against the recommendation of experts within the agency, denied Moderna's appplication. www.statnews.com/2026/02/11/m...

Announcing a new tool for "denoising" long-read amplicon sequences: savont.

Savont enables amplicon sequence variants (ASVs) directly from nanopore (or HiFi) long reads. Tested on 16S nanopore amplicons -- seems to work okay.

Lies and Lawlessness The Camps, the Executions, and the Future

We have to see the logic of the killings as well as the killings themselves. The horror is a truth in itself. But it is also a sign of a political logic, one known from the totalitarian regimes of the twentieth century.

Post from Pete Buttigieg that reads: If there was ever a moment for libertarians and conservatives to step up and join the rest of us, we’re in it. 

Americans have to unite and stop this descent from a freedom-loving nation into the kind of place where masked, militarized government agents are sent to politically noncompliant areas to roam the streets, terrorize civilians, and deploy violence with impunity.

Pregnancy loss is common in humans, and chromosomal abnormalities are the leading cause. Using genetic data from ~140,000 IVF embryos, we show that maternal variation in meiosis genes influences recombination and aneuploidy risk.

What is the contribution made by universities to their research output?

It's complicated to compute, but an estimate by MIT suggests that for every dollar they obtain from the federal government, they co-invest one dollar.

This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.
