I created an image gallery where you can see all 3 keyboard layouts shown in the keynote video today:

  - Magic Keyboard 3 (lock button)
  - Magic Keyboard 3 (Touch ID)
  - Magic Keyboard 3 (Touch ID and numeric keys, inverted T layout)

Here's what I found works or is broken in macOS Catalina and above:

The NANOGrav collaboration is trying to use millisecond pulsars to determine if a galaxy-wide analysis of 47 pulsars can detect gravitational waves.

The team says that Arecibo was instrumental for their data analysis because the telescope was unique in its radio sensitivity:

"Although NANOGrav does not expect the situation to result in significant delays in detection due to years of very sensitive Arecibo data already contributing to their datasets, the loss of Arecibo is a terrible blow to science, and will impact NANOGrav’s ability to characterize the background and detect individual sources in the future."
