Cell2fate infers RNA velocity modules to improve cell fate prediction

The cell2fate model Cell2fate builds on established concepts for RNA velocity1,2, employing a dynamical model to explain variation in spliced (s) and unspliced (u) read counts for individual genes and cells (Fig. 1a), which can be defined in two coupled ODEs: $$\frac{d{u}_{g}}{{dt}}={\alpha }_{g}(t)-{\beta }_{g}{u}_{g}$$ (1) $$\frac{d{s}_{g}}{{dt}}={\beta }_{g}{u}_{g}-{\gamma }_{g}{s}_{g}.$$ (2) Fig. 1: Cell2fate model overview. a–d, Cell2fate allows inferring complex and subtle transcriptional dynamics (a) by modeling gene-specific transcription rates (b) using a smaller number of independent modules with simple dynamics that also give rise to a modular structure in RNA velocity (c) and counts (d). λ denotes the rate of

TypeScript 5.8 reaches general availability

Microsoft’s TypeScript 5.8, the latest version of the company’s strongly typed superset of JavaScript, has reached general availability (GA). However, one new feature introduced at the beta stage, a limited form of checking against conditional types in return statements, was dropped from the GA release. General availability was announced February 28. Since the beta release, which arrived January 29, TypeScript’s builders pulled back some work on how functions with conditional return types are checked. The plan now is to iterate on the feature and release it in TypeScript 5.9. TypeScript 5.8 does add more granular checks for branches within return

Researchers Find Less-Educated Areas Adopting AI Writing Tools Faster

An anonymous reader quotes a report from Ars Technica: Since the launch of ChatGPT in late 2022, experts have debated how widely AI language models would impact the world. A few years later, the picture is getting clear. According to new Stanford University-led research examining over 300 million text samples across multiple sectors, AI language models now assist in writing up to a quarter of professional communications across sectors. It’s having a large impact, especially in less-educated parts of the United States. “Our study shows the emergence of a new reality in which firms, consumers and even international organizations substantially

SAEs trained on the same data don’t learn the same features

In this post, we show that when two TopK SAEs are trained on the same data, with the same batch order but with different random initializations, there are many latents in the first SAE that don’t have a close counterpart in the second, and vice versa. Indeed, when training only about 53% of the features are shared Furthermore, many of these unshared latents are interpretable. We find that narrower SAEs have a higher feature overlap across random seeds, and as the size of the SAE increases, the overlap decreases. This is consistent with evidence from the feature splitting and absorption

What’s the best AI model to handle $1 million in freelance software engineering?

OpenAI recently introduced SWE-Lancer, a benchmark that tests how well today’s most advanced AI models can handle real-world software engineering tasks. Even though they just tweeted about it 19 hours ago, this paper is already the top paper on AIModels.fyi in the agents category and growing fast. Their paper presents a benchmark that evaluates AI language models on 1,488 actual freelance software engineering tasks from Upwork, collectively worth $1 million in payouts. These tasks were sourced from the open-source Expensify repository. Fig 2. “Evaluation flow for SWE manager tasks; during proposal selection, the model has the ability to browse the

Top 7 meeting intelligence platforms in 2025

Companies lose millions to unproductive meetings with executives spending up to 23 hours per week in conversations that often lead to more questions than answers. Still, the real cost isn’t just time—it’s the valuable insights, decisions, and action items that slip through the cracks between meetings. Meeting intelligence platforms aim to change this paradigm. They combine advanced speech recognition, natural language processing, and conversation analytics to turn routine meetings into searchable data that drives better business outcomes. They’re not just recording conversations. They’re unlocking patterns, surfacing insights, and turning meetings into a strategic asset. However, finding the right platform for
