A little thread: Science is defiantly anti-fascist because it pursues truth, is necessarily collaborative, and relies on open communication. And because its falsifiability is incompatible with the cultism, faith-based belief systems, disinformation, and propaganda of Christian nationalism.

GWAS-informed data integration and non-coding CRISPRi screen illuminate genetic etiology of bone mineral density - Genome Biology

Background Over 1100 independent signals have been identified with genome-wide association studies (GWAS) for bone mineral density (BMD), a key risk factor for mortality-increasing fragility fractures; however, the effector gene(s) for most remain unknown. Results We execute a CRISPRi screen in human fetal osteoblasts (hFOBs) with single-cell RNA-seq read-out for 89 non-coding elements predicted to regulate osteoblast gene expression at BMD GWAS loci. The BMD relevance of hFOBs is supported by heritability enrichment from stratified LD-score regression involving 98 cell types grouped into 15 tissues. Twenty-three genes show perturbation in the screen, with four (ARID5B, CC2D1B, EIF4G2, and NCOA3) exhibiting consistent effects upon siRNA knockdown on three measures of osteoblast maturation and mineralization. Lastly, additional heritability enrichments, genetic correlations, and multi-trait fine-mapping unexpectedly reveal that many BMD GWAS signals are pleiotropic and likely mediate their effects via non-bone tissues. Conclusions Our results provide a roadmap for how single-cell CRISPRi screens may be applied to the challenging task of resolving effector gene identities at all BMD GWAS loci. Extending our CRISPRi screening approach to other tissues could play a key role in fully elucidating the etiology of BMD.

Here's the NIH's proposed budget - from $48 billion to $27 billion. NIAID, current ~$7 billion cut to ~$4.2 billion. The proposed 15% cap on indirect costs remains. Again, these budgets are passed, and our leadership in science, technology, and innovation is gone. www.hhs.gov/sites/defaul...

The end of US leadership in science, technology, and innovation. All in one little table. A tremendous gift to China, courtesy of the GOP. nsf-gov-resources.nsf.gov/files/00-NSF...

How bad will it be? Catastrophic. Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come. But, this is the WH's *proposed* budget. Speak up now before it is too late. (inflation adjusted $-s below)

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

🚨 A new rule would let career scientists like NSF/NIH program officers be replaced by political appointees Already 14,000+ public comments, deadline is Friday 📣 Comments can be short. Courts consider them—and scientists with NSF/NIH experience are especially impactful Speak up! shorturl.at/WKuBj

All of NIH funding to Northwestern University is frozen. This pause includes noncompeting approved funding, new and competing grants with fundable scores. No reimbursements for money already spent have been received since March. This situation is rarely reported so please Please get the word out!

Check this chart. Purple line: NIH actual budget (as passed by Congress) after 2000. This is in real (inflation-adjusted) dollars. The Trump/Vought proposal for 2026 (yellow) is catastrophic, for US science and medical cures for Americans. That's a massive drop.

New report shows that NIH grants fueled $95 billion in economic activity and 407,782 jobs in 2024. That's not to mention the countless lives that biomedical research has saved. Show me a better investment than that. www.forbes.com/sites/michae...

NIH Grants Fueled $95 Billion In FY 2024 Economic Activity, Finds New Report

National Institutes of Health grants generated almost $95 billion in economic activity nationwide in FY 2024 according to a new report by United for Medical Research.

I am somehow for the first time ever reviewing for PNAS and their reviewer instructions include this BANGER of a line: "The purpose of peer review is not to demonstrate proficiency in identifying flaws" Print it in eleventy point font and hang it from the hillside. Scream it from the rooftops.
