Against Malaria: My nets I've just donated to The Against Malaria Foundation, would you do your part in saving lives too?

Happy New Year. I have just donated $9,000 to malaria prevention.

This is so friggin cool. You don't have to rewrite all that FORTRAN to do autodiff on it. "Enzyme"

I love using the UKB RAP. As soon as I see that £, my brain goes "I shall keep-safe this file upon the clouds and it shall cost you nigh thruppence fortnightly." innit

Failed to weed out LLM-generated applications for bioinformatics role | Olga Sazonova, Ph.D. posted on the topic | LinkedIn Well, that's it. Hiring is f*cked. I'm just opened a contract role for a bioinformatics project. I know it's a wild market at the moment - each open role gets flooded with resumes, making it hard to separate qualified candidates from the noise. I'm convinced LLMs are partially to blame. So I devised a process to select qualified, committed candidates and avoid generic applications. Instead of resumes and cover letters, I created an intake questionnaire requiring bespoke effort to reduce cookie-cutter applications. The questions focused on specific scenarios from past experience, and therefore shouldn't be directly outsourced to chatbots. I also accidentally made the application link hard to access, but decided not to fix it. After all, computational biology often requires hacking and clever work-arounds. Finally, I included an honor code asking people not to use LLMs. Initially, I felt good about my approach. I had 20 applications after two days, and the candidates were differentiating themselves: A few didn't answer all questions, a few didn't have the right background, and several candidates provided well-written, topical, plausible answers. It was only after I read a few of these "high signal" applications in a row that the alarm bells started ringing: - Multiple candidates highlighted the same methodological paper - Many cited required skills in the exact same order - A high percentage reported identical troubleshooting scenarios involving differential gene expression studies with lab-derived batch effects The nail in the coffin was repeated phrases like "my initial hypothesis was a bug in [popular tool]" and "the spurious result disappeared." Clearly, candidates were using LLMs. Instead of learning about fitness for the role, I was learning how LLMs answer my "clever" questions. So...I failed. My approach was naive, perhaps even hypocritical. After all, I use LLMs for technical documentation myself. Still, it's really disappointing. I'm no closer to a hiring process that identifies qualified, motivated, and trustworthy candidates for remote work. Now what, y'all? | 109 comments on LinkedIn

Thanks to everyone who has supported me in large and small ways during this uncertain interval.

4) I (constructively) peer-reviewed two papers; I wrote ten blog posts; I conducted about 30 informational interviews; and I applied to about 65 jobs. It's tough out there.

3) I rode my bike from Washington, DC to Pittsburgh and back, through rain, mud, stiff headwinds, dozens of downed trees, and a couple of sub-freezing nights.

2) I defended my PhD. Ask me if you want the slides and the recording! I somehow lost track of the cute photo I was going to show. :[ Will post in replies if I can find it.

1) I have accepted a job at Alden Scientific working to improve the world's best methods for predicting long-term health.

I am proud to announce a lot of personal progress from this spring and summer. 🧵

i hope you can keep your cool through this.

I definitely think everyone working on virtual cells would be happy with more training data. What do you mean when you say the cell should be smaller?

In October 2024, I twote that "something is deeply wrong" with what we now call virtual cell models. A lot has happened since then. How am I updating? New blog post: ekernf01.github.io/virtual-cell...

Hardware/wetware codesigned data loop VISTA makes use of generative model sampling and synthesis "on chip" on-board by leveraging oligosynthesis setup shown here.

The biggest challenge for AI in biology isn't just models, it's the data used to train them. Standard biological data isn't built for AI. To unlock generative AI for drug discovery, we must rethink how we generate and capture data. 1/

Scientists often say anecdotally that RNA modifications are disrupted in immortalized cells — but no one’s really tested it.
So we did: ψ-mapping in primary T cells vs. Jurkat cells using direct RNA-seq.

BLOG ALERT! 🧬 If you do RNA-seq, ATAC-seq, ChIP-seq, or modeling thereof, you may be overlooking LD score regression methods. These should be standard tools to study genes, variants, and regions en masse, but they are hard to understand. I wrote intros:

How, then, can companies protect investments in target discovery?

Code obfuscators protect source code from reverse engineering.

Could mechanism obfuscators protect drug target identities?

Thank you. It seems this doesn't quite work to define the genetic association parameters it's supposed to define, so I will substitute another thing that makes sense to me.

Help me understand the definition of genetic covariance from the xt-ldsc paper. If beta is an argmax, then isn't cbeta also an argmax for any positive scalar c?

Interesting. I feel like this problem ought to have a general solution by now! Like a multivariate lmer or glmer package. But I am not up to date on the software ecosystem.

Jessica Jingyi Li's group has an interesting and flexible FDR control method based on simulated data. Will link . . .

Terrific opportunity. If I were not committed to the east coast for personal reasons, I would apply to this immediately.
