2,000-Year-Old Salmon DNA Reveals Secret to Sustainable Fisheries
Dan Robitzski | Nov 29, 2021 | 5 min read
Genomic analysis of ancient chum salmon bones and cultural knowledge from the Tsleil-Waututh Nation suggest that people in the Pacific Northwest managed fisheries for thousands of years by harvesting males and releasing females.

Geneticists Light Up Debate on Salmon Conservation
Christie Wilcox, PhD | Feb 1, 2023 | 10+ min read
Splitting Chinook salmon into two groups based on their DNA could aid conservation efforts. But some researchers argue that this would be a misuse of the data.
Illuminating Behaviors
Douglas Steinberg | Jun 1, 2003 | 6 min read
Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t

FEATUREThe Ecology of Tumors   Courtesy of Nasa Ames Research CenterBy perturbing the microenvironment, wounds and infection may be key to tumor development.BY PARAIC A. KENNY, CELESTE M. NELSON, AND MINA J. BISSELLNo tumor is an island. Chemical and physical forces exerted by the diverse cellular populations that surround a tumor - its so-called microenvironment - shape development and progression. Manipulating these 'ecologi
