In both biological and engineered systems, cells and sensors must make sense of noisy, changing signals to function. However, collecting and using this information consumes valuable energy. A new study, published in Physical ...
Researchers at Stanford Medicine have developed two new artificial intelligence models of the biological cell. The first, called universal cell embedding, paved the way for a second-generation model called TranscriptFormer, ...

Some types of marine life appear to have it easy. While exploring thousands of meters below the waves in the Chilean Margin in the southeastern Pacific Ocean, scientists observed tiny shrimp-like crustaceans known as amphipods ...
Researchers from Tokyo Metropolitan University have identified how certain dangerous bacteria spread. They studied chain-like adherence pattern (CLAP) varieties of Shiga toxin-producing E. coli (STEC), finding that single ...
