New computational tool helps interpret AI models in genomics Artificial intelligence continues to squirm its way into many aspects of our lives. But what about biology, the study of life itself? AI can sift through hundreds of thousands of genome data points to identify potential new therapeutic targets. While these genomic insights may appear helpful, scientists aren't sure how today's AI models come to their conclusions in the first place. Now, a new system named SQUID arrives on the scene, armed to pry open AI's black box of murky internal logic. https://phys.org/news/2024-06-tool-ai-genomics.html Molecular & Computational biology Fri, 21 Jun 2024 05:00:01 EDT news638112738 New insights into how cell shape influences protein transport rates When a cell spreads out or changes its shape to adapt to its environment, the transport rate of proteins between the nucleus and cytoplasm changes.
