Salaries of Scientists and Engineers Barely Keeping Abreast of Inflation

Response: Keeping abreast of new science.

Sinks and Jackson take strong issue with a recent paper in EHP by Gulson et al. (1) on the biokinetics of lead transfer from maternal bone and other body lead stores to nursing infants via human breast milk. I wrote an invited Research Highlights paper (2) that accompanied and discussed the larger context and implications of Gulson et al. While Sinks and Jackson did not include my paper in thei...

Python for Scientists and Engineers

D uring the past decade, Python (an interpreted, high-level programming language) has arguably become the de facto standard for exploratory, interactive, and computation-driven scientific research. This issue discusses Python’s advantages for scientific research and presents several of the core Python libraries and tools used in this domain. Although the issue’s articles are selfcontained, they...

Keeping abreast of the mammary epithelial hierarchy and breast tumorigenesis.

The epithelium of the mammary gland exists in a highly dynamic state, undergoing dramatic morphogenetic changes during puberty, pregnancy, lactation, and regression. The recent identification of stem and progenitor populations in mouse and human mammary tissue has provided evidence that the mammary epithelium is organized in a hierarchical manner. Characterization of these normal epithelial sub...
