Looking forward to talking non-perennial streams with MZ tomorrow! She'll do an overview of all of the great synthesis work in the NPS literature in the last ~5 years, and I'll do a deep dive on the organization of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) project! Join us!

Recently, all the AAAS Science & Tech Policy Fellows at EPA were terminated from our positions with little notice and for no clear reason. This effectively ended a partnership that had been going since 1980 and which had brought hundreds of scientists to the EPA as fellows, many of whom stayed. 1/7

Yesterday was the darkest day of my professional life so far. Many of NSF’s best and brightest people fired indiscriminately. The terms of their firing cruel. My colleagues matter, they are valued and they make a difference. I have no words. www.npr.org/2025/02/18/n...
National Science Foundation fires roughly 10% of its workforce
NSF fired 168 employees, leaving the agency less equipped to fund a wide range of scientific research.
