Under Trump, NOAA ran the most recent competition for their highly prestigious postdoc program in climate and global change — but funded no one, wasting huge amounts of applicant and reviewer time.
It gets a lot worse. Now current postdocs in the program are going unpaid.

Image generators are designed to mimic their training data, so where does their apparent creativity come from? A recent study suggests that it’s an inevitable by-product of their architecture.
