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

On June 14, a House Appropriations subcommittee gave some researchers cause for celebration when it surprisingly voted to remove a provision in a government spending bill that extended a ban on federal funding of human embryo research. However, their glee was short-lived. The full panel turned around on June 25 and adopted an amendment to continue the research ban. John Eppig, senior staff scientist at Jackson Laboratory in Bar Harbor, Maine, doubts that the ban will be overturned anytime soon,
