In a new work with @Josephmrich and Conrad Oakes we tackle the problem of how to best organize alluvial plots. We formalize two optimization problems and develop a solution for them based on the neighbornet algorithm, implemented in the program wompwomp: https://t.co/njQRkjYHNh

Congrats @jimmykguo and team!
Many proteins bind RNA, yet we still don’t know what RNAs most bind because methods map one RBP at a time. In @CellCellPress, with the Jovanovic lab, we describe SPIDR – a method for mapping the RNA binding sites of dozens of RBPs in a single experiment. https://t.co/Zs2Rn35D3s

Even if the awful NIH grant terminations eventually get overturned, a lot of damage has already been done. The human cost has already been paid. Scientific progress has already been delayed. Horrible. @NIH do better.
The stress has been immense. To try and save my lab, I wrote five R01 grants in three weeks, running on fumes and sleeping as little as 2.5 hours a night. This is the human cost of such unpredictable funding decisions. 10/15

Absolutely awful 😢. WTF @NIH 🤬?
My lab’s 5-year NIH R01 grant, awarded to study gene therapy for hearing loss, was abruptly terminated. I want to share how this action has been incredibly harmful and disruptive, not just to my lab, but to the scientific process itself. 1/15

This week in academia, a not so short🧵... 1. Staff reductions and other cost cutting measures coming to Brown University

The Ivy League institution's top officials signaled possible staff reductions along with scaled back capital spending and other measures.

This a really exciting leap forward for genomic sequence to activity gene regulation models. It is a genuine improvement over pretty much all SOTA models spanning a wide range of regulatory, transcriptional and post-transcriptional processes. 1/
Happy to introduce AlphaGenome, @GoogleDeepMind's new AI model for genomics. AlphaGenome offers a comprehensive view of the human non-coding genome by predicting the impact of DNA variations. It will deepen our understanding of disease biology and open new avenues of research.

Synthetic biology could enable new types of programmable therapeutics. Our new preprint introduces synthetic protein circuits that selectively trigger cell death in Ras-mutant cancer cells, with interesting advantages compared to existing approaches. https://t.co/R9kDsrftJK

Many targeted therapies indirectly suppress cancer cells by inhibiting oncogenic signaling pathways such as Ras[1][1]–[4][2]. This renders them susceptible to resistance and limits their long-term...

This is really exciting work and it is prob of interest to many of my biology-adjacent followers. The paper itself is very readable for people not doing LLM stuff and it has many nice interactive diagrams. It's just amazing to see the algorithms that LLMs learn
New Anthropic research: Tracing the thoughts of a large language model. We built a "microscope" to inspect what happens inside AI models and use it to understand Claude’s (often complex and surprising) internal mechanisms.

longcallD is a new variant caller for genomic long reads. It jointly calls phased small and structural variants. Single binary, one command line for the whole process. Comparable accuracy to mainstream callers. Great work by Yan Gao.

Tonight I found out that the NSF math postdoctoral fellowship I applied for is being deleted because it does not comply with Trump’s executive orders on DEI in the federal government. I’m going to answer some FAQs and share some thoughts about this ordeal in this thread 1/n
