Often debates about education are framed as non-tech versus AI approaches, but too often, AI ed tech just magnifies the same failures of traditional school. 1/ My latest post: www.fast.ai/posts/2026-0...

Vibe coding is the creation of large quantities of complex AI-generated code. Executives push lay-offs claiming AI can handle the work. Managers pressure employees to meet quotas of how much code must be AI-generated... yet results are far from what was promised 1/ www.fast.ai/posts/2026-0...

I had great experiences with close reading as part of this course last fall and using the solveit platform (though you can do it with other platforms, just maybe not as easily. ;-))

Close reading is a technique for careful analysis of a piece of writing, practiced by many ancient cultures, major religions, & academic scholars. The latest fastai course experimented with using AI to go deeper when reading. 1/ www.fast.ai/posts/2026-0...

A great blog post by @math-rachel.bsky.social on this preprint describing failures of an ML approach for gene annotation: rachel.fast.ai/posts/2025-0... www.biorxiv.org/content/10.1... "how challenging (or even impossible) it can be to evaluate AI claims in work outside our own area of expertise"

Two (conflicting) executive orders were made this week: - freeze on comms from scientific & health agencies - investment in medical AI w/ bold promises These highlight common misunderstandings & obfuscations about the relationship between data, AI, & power My post rachel.fast.ai/posts/2025-0... 1/

"With LLMs the main uses are to produce outputs that are extremely similar to the training set. But the point of computational drug design is to deal with cases that are new... Copying from what we know already will only get you so far." -- @dereklowe.bsky.social www.science.org/content/blog...

Nature Method of the year for 2020 was Spatial Transcriptomics and for 2024 it is Spatial Proteomics. Sounds like this is the decade for spatial -omics!

Single cell profiling obscures profound spatial heterogeneity. Even if these 4 samples had the same proportions of cell types, the spatial arrangement is vastly different. @lochlanfennell.bsky.social #multiomics2024 1/

Role of viruses in triggering Type 1 Diabetes: - viruses theorised as trigger of islet autoimmunity - both cases & controls show peptides unique to them - differential immune response to same viruses - Rather than infection with a specific virus, may be triggered by how the immune system responds

Many cancers have multiple oncogenes. Does it matter if they are in the same cell or not? -- Anand Jeyesekaran kicking off the Immuno-Oncology session for #multiomics2024 🧵 1/
Summary part 1

Sub-populations of cells have distinct combinations of oncogenes:

In DLBCL, MYC+BCL2+BCL6-cells have the strongest impact on survival

BCL6 negativity is important to assess (possible role of CCND2)

A single-cell resolved definition of DEL lymphoma as a "continuum"; extrapolatable from IHC images

Does this phenomenon (clinically relevant co-expression of oncogenes in a subset of cells) occur in other cancers?

This year I focused on how AI is being applied to immunology. These applications include predicting T cell binding, mapping immune communication networks, and discovering new antibiotics. Here is a round-up of my writing on AI + Immunology: rachel.fast.ai/posts/2024-1... 1/

Hype around AI in medicine often ignores two key risks: - patterns of automation contribute to centralization of power - medical knowledge is limited by the systemic refusal to trust patient expertise rachel.fast.ai/posts/2024-0...
