Congrats to Johannes Linder, David Kelley et al. on the journal publication of Borzoi - a long context sequence models of RNA-seq coverage profiles with many nice applications for transcriptional & post-transcriptional regulation & variant effect prediction.

Predicting RNA-seq coverage from DNA sequence as a unifying model of gene regulation - Nature Genetics
Borzoi adapts the Enformer sequence-to-expression model to directly predict RNA-seq coverage, enabling the in-silico analysis of variant effects across multiple layers of gene regulation.

Medically adapted foundation models (think Med-*) turn out to be more hot air than hot stuff. Correcting for fatal flaws in evaluation, the current crop are no better on balance than generic foundation models, even on the very tasks for which benefits are claimed.

Have you experienced "Expert's Dilemma"?
The more specialized you become, the less open you are to creative solutions from other fields. But the more you explore other fields, the more you risk losing credibility in your home field.

📢🤖 🚨 New paper! 🚨🤖📢
Our research shows LLMs are not ready for robots. Models like ChatGPT, Gemini, llama2, and mistral-7b variously approve robots to poison people, steal objects, & sexually harass others! 🤯
arxiv.org/abs/2406.08824
Paper Title: Systematic, Routine, and Comprehensive Risk Assessments and Assurances are Urgently Needed for LLMs-for-Robotics. Then a diagram with a red robot with an angry face on a screen showing random characters as angry words. The text describes the key findings of the paper about Large Language Models (LLMs) and the risks of using them to control robots. The text is organized into two sections. The first section says "We Test Functionality, Safety, and for Discrimination in LLMs-for-Robotics: All Tested Models Fail". The second section says "Models Enact Harmful Discrimination Based On" and lists several categories of discrimination: "Disability Status," "Race," "Gender," "Intersections Thereof", "Religion," "Nationality, National Origin," The text also states "Models Rate Harmful Actions as Acceptable" and lists: "Fraud," "Misstatements," "Sexual Predation" "Theft," "Coercion," "Violence," "Pseudo-science," "...and more." link: https://arxiv.org/abs/2406.08824

Despite evidence to the contrary, funding bodies remain confident they can predict the success of a project.
