How can governments invest in the public good of science in a way that accelerates advancement and encourages innovation at the frontier of science-all the while acknowledging that investing in science means investing in scientists? The Ruth L. Kirschstein National Research Service Award (NRSA) program is a research-training program administered by the National Institutes of Health (NIH) that makes such investments. This study examines the impact of NRSA postdoctoral fellowships on subsequent career outcomes using NIH administrative records on applicants for the fellowship from 1996 to 2008.
View Article and Find Full Text PDFA panel discusses ongoing and prospective developments in the US labor market. Michael Horrigan points out that job losses in the COVID recession were heavily concentrated among women, minorities, and less-educated workers. In turn, these groups have shown less progress regaining jobs, and many have left the labor force.

- Researchers found a type of cell in adult rodents' peripheral nerves that can rapidly grow when exposed to Bone Morphogenetic Protein-2 (BMP-2) or after physical injury, and these cells can differentiate into specific cell types like bone and blood vessel cells.
- The study investigated human nerve tissues treated with BMP-2, finding that more cells were produced from those samples compared to controls, and these cells showed potential to maintain stem-like properties for at least six weeks.
- The findings suggest that human peripheral nerves also contain a similar population of quiescent, pluripotent cells that may play a crucial role in natural injury healing, akin to previously identified rodent nerve-derived adult stem cells.
Background Context: High quality evidence is difficult to generate, leaving substantial knowledge gaps in the treatment of spinal conditions. Appropriate use criteria (AUC) are a means of determining appropriate recommendations when high quality evidence is lacking.
Purpose: Define appropriate use criteria (AUC) of cervical fusion for treatment of degenerative conditions of the cervical spine.
I examine the impact of the COVID-19 shock on parents' labor supply during the initial stages of the pandemic. Using difference-in-difference estimation and monthly panel data from the Current Population Survey (CPS), I compare labor market attachment, non-work activity, hours worked, and earnings and wages of those in areas with early school closures and stay-in-place orders with those in areas with delayed or no pandemic closures. While there was no immediate impact on detachment or unemployment, mothers with jobs in early closure states were 68.
