AlphaFold Opens a Free Global Library of Protein Shapes

AI-powered AlphaFold2 transformed protein folding by predicting 3D structures from sequence in minutes, leading to a public database with roughly 214 million predicted protein structures available for free. Most entries are highly accurate or confidently useful, but about a fifth have low confidence and users should filter by pLDDT. The data is CC-BY-4.0 licensed and widely used, enabling rapid research while raising questions about openness for future commercial tools and the handling of multiple conformations and disordered regions. Ongoing updates include isoforms and alignments; methods like AF-Cluster have had mixed results in extracting alternative conformations.

AlphaFold’s database adds protein pairs to map how molecules work together

AlphaFold’s database now includes 1.7 million predicted homodimer protein complexes, expanding its 200 million monomer structures to show how two copies of the same protein interact. The complex predictions were produced by a international consortium and are freely accessible via EMBL-EBI, broadening the resource’s biological and medical relevance across 20 studied species.

Evo 2: An Open-Source AI for Genome-Scale Prediction and Design Across Life

Evo 2 is a large, open biological foundation model trained on 9 trillion base pairs across all life, with a 1‑million‑token context, available in 7B and 40B sizes. It predicts mutational effects on DNA, RNA and proteins without task-specific fine-tuning, can generate genome-scale sequences and chromatin-accessibility designs, and supports exon–intron annotation and variant-effect prediction across diverse species. The model and data (OpenGenome2) are fully open-source, with training/inference code and tools (Evo Designer, Evo Mech Interp), plus safety safeguards such as virus-data exclusions to mitigate misuse.

Evo: The AI Revolutionizing Genetic Prediction and Design

Scientists have developed Evo, a machine learning model that predicts the effects of genetic mutations and generates new DNA sequences with high accuracy. Unlike traditional large language models, Evo is trained on microbial genomes, using base pairs as "words" to analyze genetic patterns. While Evo shows promise in understanding DNA and RNA functions, it currently lacks the ability to predict human genetic mutations. The researchers emphasize the importance of ethical guidelines to prevent misuse as the technology advances.

"New Atlas Reveals Gene Functions in Early Embryo Development"

Researchers at UC San Diego have developed a "genetic atlas" using the model organism C. elegans to profile the function of nearly 500 genes during embryonic development. By blocking each gene one at a time and using time-lapse 4D imaging and computer vision, they tracked how these genes influence tissue formation and cell identity. This study, published in Cell, provides new insights into gene functions and their roles in development, with implications for understanding human developmental disorders. The data is now available through an online resource called PhenoBank.
