Bacteria and Humans Have Been Swapping DNA for Millennia
Kelly Robinson and Julie Dunning Hotopp | Oct 1, 2016 | 8 min read
Bacteria inhabit most tissues in the human body, and genes from some of these microbes have made their way to the human genome. Could this genetic transfer contribute to diseases such as cancer?

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
Who Sleeps?
The Scientist and Jerome Siegel | Mar 1, 2016 | 10+ min read
Once believed to be unique to birds and mammals, sleep is found across the metazoan kingdom. Some animals, it seems, can’t live without it, though no one knows exactly why.

Elusive "Pingelapese Blindness" Gene Identified Before there was Survivor, the hit summer TV show, there was Pingelapese blindness, a classic example of a population bottleneck. In 1775, a typhoon devastated Pengelap, a coral atoll in the Eastern Caroline Islands in Micronesia. Of the 20 survivors, one male passed along a recessive gene for achromatopsia, and four generations later, the condition began to appear, thanks to two centuries of isolation and inevitable inbreeding. In the condition,
60 Members Elected to NAS

Editor's Note: On May 2, the National Academy of Sciences announced the election of 60 new members and 15 foreign associates from nine countries in recognition of their distinguished and continuing achievements in original research. Nearly half of the new members are life scientists. In this article, The Scientist presents photographs of some of the new members and comments from a few of them on their careers and on past and current research. A full directory of NAS members can be found online a
Researchers Receiving MacArthur Fellowships Demonstrate 'Capacity To Make A Difference'
Bruce Anderson | Sep 14, 1997 | 6 min read
PRIZE WITH A PRICE: Science historian Peter Galison has taken some ribbing from his family since being named a MacArthur fellow. One could almost pity Peter Galison. A historian of science at Harvard University, Galison is one of seven members of the scientific community among the 23 recipients of this year's John D. and Catherine T. MacArthur Foundation Fellowships. The coveted five-year awards provide unrestricted support plus health insurance to talented individuals, with no reports or proj
