We like to introduce map3C, developed by Joseph Galasso, that drastically improves the mapping and contact calling performance of snm3C-seq and now enables accurate 3D genome modeling. map3C was developed in collaboration with

Preprint alert: single-cell methylation signature of autism in collaboration with Dan Geschwind. Autism-mC signal is enriched in promoters and cell-type enhancers but uncorrelated with gene expression. Led by @GeschwindLab Postdoc Katie Eyring and grad student Cuining Liu.

As many of us in genomics know, NIH's bread & butter mechanism historically struggles to fund data generation due to the "hypothesis-driven" dogma. Instead of sporadically using the RFA to fund data generation, this is the time to have a core structure
March 4, 2025 at 7:25 PM
assuming NIH survives the current trauma, it needs to develop innovative structures to fund SO MUCH data generation to support the AI-powered discoveries unless the plan is to cede the job to @cziscience or start-ups like vevo_ai
March 4, 2025 at 7:25 PM
I don't know how the dogma that "research should be hypothesis-driven" can still operate in the era of rapid data interpretation by AI models. In the past 25 yrs, genomics field has advocated for systematic data generation the debate may be now settled by the data-hungry models

Illumina looks pretty good this yr with constellation, single cell, spatial, and five base after I don’t even know how many yrs of looking boring. #AGBTGM

Does ambient RNA/DNA confound the genotype-based demultiplex of 10x Multi-ome data? Terence Li, a bioinfo grad student in Noah Zaitlen lab and my lab investigated precisely this question and provided practical recommendations. www.biorxiv.org/content/10.1...

It’s been a tough few weeks. My 10yo daughter was diagnosed with a very rare, aggressive cancer called interdigitating dendritic cell sarcoma (IDCS). I’m reaching out to identify clinicians/patients who have encountered pediatric IDCS or other (non-LCH) dendritic or histiocytic sarcomas cases.

1/ I am beyond thrilled to share our new paper in @CellCellPress! We explored the regulatory principles underlying pleiotropy in psychiatric disorders.

Massively parallel reporter assay investigates shared genetic variants of eight psychiatric disorders
High-throughput experimental validation of genetic variants linked to eight psychiatric disorders reveals the regulatory mechanisms underlying variants with pleiotropic and disorder-specific effects.

Paperpile @paperpile.com works best if all references are imported using PMID. Letting Paperpile search from random Web sources causes inconsistency in formatting and missing PMCID.
January 24, 2025 at 5:03 PM
Paperpile @paperpile.com can you remove URLs from the "National Library of Medicine (grant proposals with PMCID/PMID)" format? This format is fantastic but NIH does not allow URLs in grant proposals

~20 yrs ago I chose bio major because bio requires the least amount of math but look where we are now

Not publishing that last dull paper from the old lab is always a mistake because track records belong to you, not just to the lab, and you don't know how well the new thing/place will work out and maybe that dull paper will get you the next big job, you never know.

I am lost in why NIH issues all these NOSIs with no dedicated review panel and no allocated budget. Giving the impression of top-down planning (which many people dislike) but giving no priority to people who respond seems to defeat a whole lot of purposes all at the same time

the late 2020 H1B rule change raised minimal salary to $85k and that applied to cap-exempt academic H1B. That was about to eliminate >5 yr positions (beyond J1) for many international postdocs. If comes back, an $100k line would be nothing for tech but a big problem for labs

If you wonder why people have jumped into scRNA-seq and CRISPR in an almost uninspiring way, a simple explanation is that the shortage of methods for measuring and modifying remains the bottleneck of biology and will remain so for a long time.
have ppl found any funders that support toolmaking? I want to keep making tools for people, but there is a seemingly irresistible force pushing us towards hypothesis-driven research. In my experience, funders don't want to hear about tech dev. Any insights? for both neuro & climate would be great tx

However, I did notice the possibility that some grad school applicants abuse bioRxiv by posting manuscripts that practically can't get through any serious peer review.

bioRxiv has transformed the publication of biological research. All these tweaking of open access policy, not so much.

The impact of luck is one of my favorite topics when I talk about scientific careers with family & friends. Basically, I think luck is a lot more important than my effort.

Hiring more faculty straight out of grad school is one of the best ways to make academia healthy again!
