A new research paper describes a statistical framework that resolves significant calculation biases caused by artificial intelligence in econometric models. The method, two-step extraction, removes estimation bias when researchers measure the business or economic effects of variables extracted using machine learning algorithms from unstructured data such as photos and consumer text.

Earth's slowing spin may have shaped its primordial crust

Around 4.5 billion years ago, a planet-sized object collided with the newly formed Earth, throwing out the debris that would later form the moon. The collision left Earth spinning extremely fast, with days lasting just two to five hours. Yet existing models of how Earth's first c
