2. Google DeepMind’s AlphaFold 3 Predicts Protein-Drug Interactions
Source: Nature, November 22, 2025
AlphaFold 3 extends beyond protein structure prediction to accurately model protein-ligand and protein-DNA interactions. This enables faster drug discovery and understanding of disease mechanisms.
Why It Matters: ML infrastructure engineers should note the architectural patterns—DeepMind’s use of diffusion models combined with transformers represents a convergence of techniques applicable to other complex prediction problems.

3. Rust 1.84 Introduces Async Traits Stabilization
Source: Rust Blog, November 23, 2025
Long-awaited async trait stabilization landed in Rust 1.84, removing the need for async-trait crate workarounds. The release also includes improved compile times and better error messages.
Why It Matters: For teams building high-performance services considering Rust as a complement to Go/Python, this removes a major ergonomic barrier. Async traits enable cleaner abstractions for network services and database drivers.
