Also for #FossilFriday - the @societyofvertpaleo.bsky.social has released this statement re: the US administration's recent decision to dismiss all members of the US National Science Board. 🧪
Statement from the Society of Vertebrate Paleontology re: the US administration's decision to dismiss all members of the US National Science Board:

"The Society of Vertebrate Paleontology joins with the American Institute of Biological Sciences (AIBS) in its profound opposition to the U.S. administration's decision to dismiss all members of the National Science Board (NSB). This unprecedented action bypasses the critical guardrails established by the U.S. Congress to ensure that federal scientific research remains independent and free from political influence.

"The Administration's decision not only threatens to further erode public trust in federal science, but also eliminates the public's opportunity to independently assess that trust for themselves. Such actions strike at the very heart of the democratic process. SVP calls upon Congress and the Courts to stand up against the politicization of science and the independence of scientific endeavor- an independence that has until now marked the United States as a global leader and partner in scientific research and innovation."

Last Friday, Trump fired the National Science Board. The NSB is made up of distinguished scientists whose job is to oversee the National Science Foundation, setting research priorities by thinking beyond election cycles. It was designed to be independent. We don't know what this means, but it's bad.

Saw some discourse about the issue of older professors not retiring as if that’s the roadblock to younger academics securing jobs. This despite every institution I’ve worked at simply not filling lines when professors retire, which seems a much more prominent trend.
