Asgard archaea: our 38th-cousins 63 times removed (or something like that)

Current NIH leadership want you to think they are using rigorous, consistent & scientific processes to screen studies to align them with agency priorities.

But the process that they have put down on paper is a sham.

It’s important to know NIH is not following its own guidance. Here’s why:

Just over ten years after the discovery of the first Asgard archaeal genomes, we revisit the rapid expansion of this remarkable archaeal lineage. From diverse genomes and metabolisms to eukaryotic signature proteins and the first cultured representatives.

An announcement that the Senate voted to reauthroize the SBIR/STTR program.

The Senate has (finally) voted to reauthorize the small business SBIR/STTR program.

Not reauthorized yet, but this was likely the biggest hurdle.

NIH Director is an incredibly important and consequential job. Statements like “we believe in supporting early career researchers” must be met with data. Not just anecdotes.

The data is showing something that’s different from rhetoric and anecdotes…

White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. 🧵👇

Line graph of the number new and competitive renewal grants funded by NIH in fiscal year 2026 through February 20, compared to fiscal years 2020-2025. The fiscal year 2026 is well below the other curves.

New and Competitive Renewals

Only 803 grants have been made compared to ~2650 in fiscal years 2023 and 2024 through February 20.

All institutes and centers (include OD now) have made awards except NIAAA, NLM, NCCIH, and FIC.
