National Science Foundation Terminates Hundreds of Active Research Awards (Gift Article) The agency targeted grants focused on diversity, equity and inclusion, as well as research on misinformation.

Universities like mine are limiting hiring, travel, and other spending using federal funds because of the fear of things like this. It's basically impossible to do science, whether NSF takes back funding or not.

One of the most disheartening experiences for me over the past 80 days has been the shattering of the illusion I harbored that academia (particularly wealthy private institutions filled with smart people) would uphold and fight for the ideas and values we cherish.

What the NSF is doing this week is damaging *generations* of scientific researchers and American investments in science. Billions of US tax payer dollars in investment, being thrown away, because of a fucking fishing expedition that is intended to terrorize and set the stage for a real witch hunt.

I'm an origamist, papermaker, ethnobotanist, and plant conservationist. The execution of my art is directly informed by my background in botany, and by the collaborations and partnerships I maintain with papermakers in Vietnam, Mexico, and Nepal.
