ChatGPT, the artificial intelligence tool that has been used in everything from high school essays to a speech on the floor of Congress, has added another accomplishment to its résumé: passing exams from law and business schools.

The AI tool was presented with several tests from both the University of Minnesota’s law school and the University of Pennsylvania’s Wharton School of Business, passing them all.

That said, the AI didn’t necessarily ace the exams with flying colors. The chatbot answered 95 multiple choice questions and 12 essay prompts across 4 of UM’s law school tests, averaging about a C+ performance overall. The tech did better in Wharton’s business management course exam, scoring between a B to B-.

CRISPR gene editing created the G795A amino acid which was introduced to microglia derived from human stem cells. Researchers were able to transplant the donor microglia immune cells into humanized rodent models while administering an FDA-approved cancer drug called pexidartinib. The inclusion of the amino acid cause the donated microglia to thrive and resist the drug, while the host microglia died. The findings open the door for new methods of using microglia to treat a range of neurodegenerative disorders.
