Animal Divorce: When and Why Pairs Break Up

Many species of birds and other vertebrates form pair bonds and mate with just one other individual for much of their lives. But the unions don’t always work out. Scientists want to know the underlying factors.
Outsmarting Influenza's Rapid Evolution
Philip Hunter | Jun 29, 2003 | 7 min read
Twice yearly, World Health Organization health officials meet to strategize against influenza, a malady that kills at least 250,000 people each year. In a chess match of sorts, they work to predict their opponent's next move, in this case by modifying vaccines to compensate for changes in the critical viral antigen hemagglutinin, which triggers the host's long-term immune memory. It takes several months to manufacture and distribute flu vaccines in sufficient quantities to inoculate vulnerabl

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
