The NIH Restructuring Congress Rejected Is Happening Anyway (I used Gemini Nano Banana 2 to create this fictional image.)

The impact is already hitting science agencies hard. The NIH—the world's largest public biomedical research funder—has had to rely on leftover stopgap funds.

New grant awards have slowed to a trickle — exacerbating the effects of a record-long shutdown in October.

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. 🧵👇

Yesterday, five-year-old Liam and his dad Adrian were released from Dilley detention center. I picked them up last night and escorted them back to Minnesota this morning.

Liam is now home. With his hat and his backpack.

We mapped the fitness landscape of the 10kb MYC locus using SpRY-Cas9 saturation mutagenesis. 67% of the essential bps are noncoding. So even for a protein coding gene locus, most genetic information may be encoded outside of coding regions.

Does the noncoding genome actually carry more genetic information than coding seqs? Motivated by this question we mutated every bp in the 10kb MYC locus. Results are even more exciting: Decoding the MYC locus reveals a druggable ultraconserved RNA element www.biorxiv.org/content/10.6...

Getting here wasn’t a straight path. We discussed the story behind the model, paper & API in the following roundtable: youtu.be/V8lhUqKqzUc

An NIH source tells me that after this story was published, agency leadership held an emergency meeting about Council approval and is looking for ways to speed up the pipeline.

"Better late than never?" the source says.

What Happens After a Child Is Taken Into ICE Custody? Five-year-old Liam Ramos' detention by ICE has sparked questions about the policies underlying the agency's deportation operations.

ICE has detained at least 3,800 kids under the second Trump administration — more than 500 of whom were under 5 years old.

Children shouldn't be locked up by our government.

New preprint on technologies to scale up CRISPR screens.

We use them to map 665,856 pairwise genetic perturbations and outline a path to comprehensive interaction mapping in human cells.

We also introduce an approach for cloning lentiviral libraries with billions of elements.

Junction-targeting designs limit the application of CRISPR-Cas13d in circular RNA perturbation studies Abstract. Circular RNAs (circRNAs) are RNA molecules formed through the backsplicing of linear exons. Several thousand have been identified, yet relatively

How can we identify circRNAs that might be functional?

Together with @jengreitz.bsky.social, Howard Chang, and team, we found that answering this question is much more challenging than previously thought!

TLDR; TFIID behaves differently depending on promoter type. More below:

High false sign rates in transcriptome-wide association studies Transcriptome-wide association studies (TWAS) are widely used to identify genes involved in complex traits and to infer the direction of gene effects on traits. However, despite their popularity, it r...

How well does TWAS estimate a gene’s direction of effect on a trait? We think of this as an important stress-test for the accuracy of TWAS.

In a new pre-print, we find that TWAS gets the sign wrong around 20-30% of the time!

Do transcriptional activators work on any promoter? Our data says no. 🙅‍♂️
Despite driving ~2/3 of mammalian genes, CpG island (CGI) promoters have remained a puzzle. We identified >50 activators that are exclusively compatible with this promoter class. 🧬
