Google published a new blog about how students can use NotebookLM, and there are 3 new features:

• Reports got a redesign & upgrade: there's a new report format called "Blog Post" (hmm), and it will now suggest a report format for you based on theme, topic, industry. You can also create custom report formats.
• NotebookLM partnered with OpenStax and turned their most popular content into curated interactive notebooks (Biology, AP Biology, Intro to Business, Chemistry, Psychology, Principles of Management)
• Teachers can create notebooks from class materials and assign them in Google Classroom
