THREAD. Every year, I tell the story of Ezell Gilbert. It's the story of one of the most remarkable cases in U.S. history, and you’ve probably never heard of it. The story of what the U.S. government did to him is vital for understanding the current moment we are in.

She really was an extraordinary and visionary leader, and I have no doubt she would have made a fine Chief Scientist one day.

ARC says they’ll announce DECRA and LIEF outcomes tomorrow (Tuesday 25th Nov).
In recent times these announcements have been around 11am Canberra time. With 2 schemes on the same day, I assume they’ll announce one of them later in the day (probably DECRA first).
