“We live in an infinite sea of rats.” UC ANR human-wildlife interactions advisor Niamh Quinn explains the challenge of rodent control: beyond any control project, there are more rats ready to move in. The goal isn’t elimination, it’s effective management. www.theatlantic.com/science/2026...

Good end-of-FY coverage by the Times. The amount of unspent funds has wiggled but it was pretty clear for some time now that NSF was simply not going to spend a substantial portion of its congressional appropriation this year.

National Science Foundation Diverted $1.4 Billion in Science Funds Mandated by Congress
The move, affecting about one-fifth of the National Science Foundation’s primary research budget, is the latest sign of how the White House is asserting more control over grants.

The Department of Integrative Biology at UT Austin has two open positions for assistant professors, one in evolutionary biology and one in mechanistic processes. Please share. Apply here: apply.interfolio.com/193270
Two Assistant Professor Positions in Evolutionary Biology and Mechanistic Processes

Description
The Department of Integrative Biology at The University of Texas at Austin seeks to fill two faculty positions in the areas of Evolutionary Biology and Mechanistic Processes, broadly defined. We are looking for candidates who are advancing (1) evolutionary biology or (2) the mechanistic understanding of organismal processes. These positions will be filled at the level of Assistant Professor.


Qualifications
Candidates should be using innovative approaches in evolutionary biology and/or the mechanistic understanding of whole-organism processes. Mechanistic processes include, but are not limited to, behavior, biomechanics, cognition, physiology, and development. The phylogenetic scope of the Evolutionary Biology position may include eukaryotes, prokaryotes, viruses, and the scale may include individual molecules to entire ecosystems and beyond. Candidates for either position may employ experimental, theoretical, or computational frameworks, or a combination thereof. Special consideration will be given to applicants with demonstrated potential for integrating across our target disciplines. 

We seek applicants with a strong record of high-quality research, publications, potential for extramural funding, and a commitment to excellence in teaching and mentorship. A PhD or equivalent is required at the time of appointment, and postdoctoral research experience is strongly recommended.
