Peter MombaertsCourtesy of Peter MombaertsRarely do scientific studies claim that something is not the case. Rarer still do negative results appear in top-tier journals. Yet two recent papers in Nature describe what olfactory sensory neurons do not do.12The olfactory system is often compared to the immune system. The key cell types in each system, the olfactory sensory neuron (OSN) and the lymphocyte, can detect a wide variety of chemicals, both natural and synthetic. Chemical recognition by the
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
Exotic Species, Locales All In Day's Work For Conservation Biologists
Karen Young Kreeger | Jan 22, 1995 | 9 min read
Traveling to the ends of the earth in pursuit of biological quarry is not part of the job description for the average molecular biologist. But for anthropologist Don Melnick, going to work means trekking through the jungles of Southeast Asia for blood samples from the Javan silvery gibbon and other endangered animals. And the jobs of geneticist John Avise and biologist Brian Bowen entail long nights on tropical beaches waiting for nesting sea turtles. The following are the top ecology journal
