Published an op-ed for @cnn.com: “Nobel laureate: I owe America my success. Today, its scientific future is in danger.”
A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world.

I could not be more excited to have our lab's first story online where we report our discovery that HDACs ~reverse~ their activity to ADD acyl groups to lysine! We found this for our favorite ketone body, BHB, but this pathway controls other lysine modifications too!🧵

Just look at these paragraphs from the AP story.

Hegseth called Brown unqualified solely because he's Black. Then they fired him... and replaced him with a white guy so indisputably unqualified that he requires a Presidential waiver.

This is what "merit" means to them.

Can I give some unsolicited advice? When communicating on this catastrophe, don’t lead with “I know the NIH is inefficient and needs serious reform, but…”. You are undercutting the entire message and buying into the frame of the arsonists. This is not a scientist audience. No “to be fair” points

I’m reaching out to my vendors to push them to use their lobbying infrastructure to point out the devastating effects the NIH change will have on the USA’s R&D engine.

all y'all academics who have been naively convinced IDC only goes to useless sub deans are about to find out. they are going to claw the real costs of research out of your unchanged direct costs.

Indirect rates are not determined by NIH. Instead, they are the product of elaborate negotiations between each institution and the “cognizant federal agency” according to an Office of Management and Budget document, Circular A-21.

1. Today the NIH director issued a new directive slashing overhead rates to 15%.

I want to provide some context on what that means and why it matters.

We just upgraded one of our Illumina NovaSeqX’s to enable the new 25B 100 and 200 cycle kits. New software is supposed to slightly raise PF% and we are seeing that. 10X GEX libraries previously generated 32B reads per flow cell. We seeing over 33B, almost 67B reads in 24 hours for a dual FC run!

We just got our n6 Tec iconPCR installed. The system monitors NGS library amp with real time functions but each of the 96 wells is independently temperature-controlled and monitored. This is super helpful when you have varying inputs. www.n6tec.com

The new MiSeq i100 should be good to check pooling for the NovaSeqX. Catherine's group is seeing good consistency between the two platforms, but from first glance, it does appear the MiSeq i100 is more consistent with the older iSeq (blue and orange lines).
One application for which we want to use the Illumina Miseq i100 is to QC pools pre-NovaseqX run. Our initial tinkering, involving sequencing the same pool on the i100, Iseq, & X, show that the read counts on the i100 are closer to the Iseq counts, and both are reasonably close to the X counts.

The #illumina #NovaSeqX 25B 100 cycle kits should be released sometime this month. These further reduce the cost of applications like single-cell sequencing by ~20%. Besides a cost reduction, the runs will take ~24 vs 48 hours, increasing the throughput of our machines.

Remember when @pacbio.bsky.social introduced Kinnex and customers suddenly got >40M HiFi transcripts per run? I was tasked to solve scaling up Iso-Seq reference-free clustering and had less than a month. There were a lot of #bioinformatics challenges to be solved
