Creating the perfect morsel of meat: Engineers develop metamaterial that mimics the structure of muscle and fat
Lamb chops – wood. Credit: Hebrew University In a new publication in Nature Communications, Israeli and Palestinian engineers at the Hebrew University of Jerusalem have pioneered the use of metamaterials to create whole meat. This effort leverages cutting-edge materials science to overcome the long-standing challenge of recreating the texture and structure of traditional meat while providing a scalable and cost-effective…

New computational model allows more accurate prediction of antibody structure
Overview of AbMAP embedding generation and its architecture. (A) Given an input antibody sequence, the pipeline generates embeddings that can be applied to various downstream tasks such as structure/property prediction and antibody repertoire analysis. (B) The AbMAP pipeline begins with in silico mutagenesis focused on the CDRs of the input antibody sequence. These are fed into the AbMAP transformer architecture,…
