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.

Cover of Science magazine for July 30, 2026. Caption from Science reads: A three-dimensional rendering shows the land bridge connection between North and South America. Research on the fossil record of mammals in Mexico suggests that the geographic region acted as a biodiversity “holding pen” for 10 million years, buffering the pace of both northward and southward movements of mammal species leading up to the Great American Biotic Interchange.

Y'all - the Smithsonian is hiring three new curators - herpetology, ichthyology, and ornithology! Notably, this is a 2nd fish curator position - i.e., not the same as the one advertised last month. So if you applied for that one apply again. www.usajobs.gov/job/873849000
Curator of Vertebrates

Smithsonian’s National Museum of Natural History currently has openings for three early-career Research Curators in Vertebrate Zoology, one each from the disciplines of ornithology, herpetology and ichthyology. The Department of Vertebrate Zoology seeks candidates with demonstrated expertise in, and a commitment to, collections-based research centered on systematics and evolution of birds, reptiles, amphibians, and fishes. This includes the ability to pursue an original approach to systematics and comparative analyses using, for example, morphology, development, and/or molecular data, and showing evidence of broader impacts or applications in evolutionary biology and/or collections-based ecology, as demonstrated by a record of peer-reviewed publications.

Candidates must have demonstrated the ability to establish an externally funded research program and to contribute to the growth and curation of the collections. Research in the Department is supported by the Museum’s shared laboratories, including the Laboratory of Analytic Biology and the Scientific Imaging facility, among others. The Department’s scientific collections are the largest in the world for fishes, amphibians, and reptiles, and the third largest for birds.

These federal positions will be filled at the GS-12 level, with a starting salary of $102,415, and excellent benefits. The positions are permanent and require a one-year probationary period. 

The official announcement is posted on USAJOBS, where applications must be submitted.
https://www.usajobs.gov/job/873849000

Please be sure to read the announcement and instructions carefully, as the process of applying via USAJOBS is stringent and differs from applying for an academic position. This website offers helpful advice: https://serc.si.edu/careers/tips-applying-federal-jobs

Please contact the Search Committee Chair, Michael McGowen (mcgowenm@si.edu) or the Department Chair, Helen James (jamesh@si.edu) with any questions.
