Most disease-causing bacteria are known for their speed: In mere minutes, they can double their population, quickly making a person sick. But just as dangerous as this rapid growth can be a bacterium's resting state, which helps the pathogen evade antibiotics and contributes to severe chronic infections in the lungs and blood, within wounds, and on the surfaces of medical devices. Now, scientists have discovered how long chains of molecules called polyphosphates (polyP) are needed for bacteria to slow down movements within cells and let them enter this resting state.

Tyche is a machine-learning framework that can generate plausible answers when asked to identify potential disease in medical images. By capturing the ambiguity in images, the technique could prevent clinicians from missing crucial information that could inform diagnoses.
