**Enhancing the performance of proton exchange membrane water electrolysis by constructing electron/proton pathways**
The proton exchange membrane electrolysis of water (PEMWE) is a critical process for hydrogen generation. However, the limited ability of electrons and protons to permeate the membrane and the inefficient arrangement of the transport structure in the catalyst layer (CL) presents significant obstacles to the widespread adoption of PEMWE. ⌘ Read more

**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 ... ⌘ Read more
