Thom Graves MediaThe audience, several hundred biophysicists strong, was not expecting a James Brown impersonation. But there he was: Physiologist Yale Goldman, keynote speaker on motility at the Biophysical Society's annual meeting, doing his "asymmetric hand-over-hand motility dance with a limp" to tinny strains of "Papa's Got a Brand New Bag." And while Goldman, who eschewed Brown's trademark, over-the-top couture for understated, Ivy League-issue khakis and blue blazer, won't star on MTV any

DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.
To Effectively Discuss Evolution, First Define 'Theory'
Ricki Lewis | May 11, 1997 | 9 min read
Evolution is the backbone of modern biology, but life scientists sometimes face audiences who perceive it as a threat to their religious beliefs. With laws such as North Carolina House Bill 511, proposed in March as an attempt to "ensure that evolution is not taught as fact in North Carolina public schools," scientists are being asked to clarify the distinction between science and religion. Professors at small Southern and Midwestern colleges seem to have the most experience in discussing-and s

F. Stuart Chapin III, known as Terry, has been a professor of ecology at the University of Alaska Fairbanks since 1973. He studies the effects of changes in climate and wildfire on Alaskan ecology, with a particular focus on developing sustainable ecosystems and human communities. In this issue, Chapin introduces a five-part feature on the effects of climate change on the biosphere. "Scientific assessments now clearly demonstrate the ecological and societal consequences of huma
