    "body_text": "A Boston College-led team used a scanning quantum sensor to image a van der Waals spin transistor during switching. The device operated in a space-charge-limited regime and reached an electrical on/off ratio reported at one million percent and a magnetic ratio of 3,000 percent. The laboratory result points toward logic and nonvolatile memory in one component, but it is not yet a production processor.",
