This session will announce the launch of Nightingale Open Science and feature a demonstration of the product. Today, health data are mostly locked up in small sandboxes, controlled by a handful of private companies or well-resourced researchers. Nightingale Open Science aims to unlock those data, securely and ethically, and make them available for the public good. Just as ImageNet jumpstarted the field of machine vision, Nightingale seeks to build a community of researchers working in a new scientific field: ‘computational medicine.’ Nightingale OS datasets are curated around medical mysteries—heart attack, cancer metastasis, cardiac arrest, bone aging, Covid-19—where machine learning can be transformative.
