Super excited to get this out. This collab started a few years ago and is the first paper from it. Here, with experimental and computational approaches we:

1. establish that cell villages can be just as accurate (one might argue more accurate!) than arrayed-based designs

Happy to see the ENCODE4 long-read RNA tracks now up on UCSC! Thank you to Jeltje, Mark, and any others at UCSC for working to make this happen 🤩

Many proteins bind RNA, yet we still don’t know what RNAs most bind because methods map one RBP at a time. In @cp-cell.bsky.social, with the Jovanovic lab, we describe SPIDR – a method for mapping the RNA binding sites of dozens of RBPs in a single experiment. www.sciencedirect.com/science/arti...

Super proud of my first student, @jingyour.bsky.social! Well done! Looking forward to the amazing work you will do in the future 🥲 bsky.app/profile/jing...

Thanks Harold! :)

Congratulations to Anne Kil on successful defense of her PhD! Her thesis focused on engineering solutions for saliva as a biomedical diagnostic, from improved collection asmedigitalcollection.asme.org/medicaldevic... to assessing the potential of saliva multiomics www.biorxiv.org/content/10.1...

Congratulations to @delaneyksull.bsky.social on successfully defending his PhD (photo below with his committee: Barbara Wold, @mitchguttman.bsky.social, and another of my former students @hjp.bsky.social).

His thesis is on software, tools, and methods development for single-cell transcriptomics.

Very excited to finally see this out! 🦠🧬

Huge thanks to all of my amazing co-authors! @lpachter.bsky.social @delaneyksull.bsky.social

New preprint out!
This is probably my most important paper. To my deep chagrin, it has no math.
XIST is a non-coding RNA exclusive to XX females. It silences one of the X chromosomes.
So what is it doing in male heart Schwann cells?

New lawsuit filed today in Massachusetts aginst NIH from many state Attorneys General

First, plaintiffs seek relief for the unreasonable and intentional delays currently plaguing the grant-application process

🚨 BREAKING: I'm suing #RFKJr @ #HHS & #JayBhattacharya @ #NIH

Canceling medical research grants threatens innovations benefiting ALL Americans, no matter your politics! 🇺🇸

Thanks to my lawyers @aclu.org @aclum.bsky.social @protectdemocracy.org & @cspi.bsky.social

Long 🧵 on why I'm suing 👇

1/

ACLU sues National Institutes of Health for ‘ideological purge’ of research projects The lawsuit says that NIH has canceled more than 670 research grants, which were due more than $1.1 billion in funding.

www.nbcnews.com/health/healt...

Revoking Congressionally appropriated funds based on political ideology is not just undemocratic, it's illegal. It's a gross misuse of American tax dollars, and it recklessly endangers everyone.

Grateful to my colleagues for standing against this. Enough is enough.

Oof!

Same situation with me :/ Literally was just one step away from the NOA. Can’t resubmit b/c of my graduation timeline.

I am livid that my student who submitted a diversity F31 and received an outstanding score, near the top of the fundable range, was told to submit again.

Refusing to fund F31s from URMs while funding regular F31s from white/privileged students with worse scores is blatant discrimination.

Just wanted to give a shoutout to @marimo.io (cc @akshaykagrawal.bsky.social ). If u have been using Jupyter Notebooks, u should REALLY try Marimo. It is such an upgrade. We have been actively developing on it in the lab (integration with NLP LLMs) as well & are huge fans. Strongly recommend.

@jeremymberg.bsky.social Just now, they removed the funding opportunity page (PA-23-271) and updated grants.gov page to have a closing date of Feb 21 and an archive date of Feb 22. Wtf is going on?

Trump Administration Stalls Scientific Research Despite Court Ruling (Gift Article) Using an arcane law, officials have effectively delayed funding from the National Institutes of Health, leaving medical studies in jeopardy.

I had one submitted last April; no NOA after JIT, but at least it hasn’t disappeared from era commons.

Interested in being connected

for any others who applied to diversity-related NIH grants that are being affected by the DEIA ban, if you'd like to join a whatsapp group (for support + looking into legal options) reply to this post & i'll DM you a join link!
