Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
A Genomic View of Oceanic Life
Leslie Pray | Oct 14, 2001 | 6 min read
Last year, scientists discovered a unique, energy-generating, light-absorbing protein previously unknown to exist in oceanic life. They named the protein proteorhodopsin.1 The bacteria that harbor it are a distinct phylogenetic group known as SAR86. This year, scientists learned that as much as 10 percent of the ocean's surface is occupied by these proteorhodopsin-containing bacteria--as many as 1x105 cells per milliliter of sea water.2 The researchers, led by marine microbiologist Edward DeLo
An Ocean of Viruses
Joshua S. Weitz and Steven W. Wilhelm | Jul 1, 2013 | 10+ min read
Viruses abound in the world’s oceans, yet researchers are only beginning to understand how they affect life and chemistry from the water’s surface to the sea floor.
Iron Seeding Just Doesn't Pay

BRINGING ON THE NEXT ICE AGE?Dee Breger, Drexel UniversityAssumptions that tiny diatoms such as the ones shown above could fix carbon from the air and sink it to the bottom of the ocean have been hard to prove.The US Department of Energy has taken an interest in carbon sequestration, but a grand scheme to induce thick blooms of carbon-fixing algae has yet to bear fruit in early studies. The DOE directs a large share of its global warming budget to carbon-sequestration research, drawing on biolog
Imaging Chromatin to Deduce Function from Form

Researchers describe their tools for probing how the physical shape of the genome affects genes’ function.
Opinion: Learning from Transcriptomes
David Smith | Nov 28, 2012 | 2 min read
In the largest microbial eukaryote genetic sequencing effort ever attempted, researchers are investigating the transcriptomes of 700 marine algae species.
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
How Interconnected Is Life in the Ocean?

To help create better conservation and management plans, researchers are measuring how marine organisms move between habitats and populations.
Research On Global Climate Heats Up
Elizabeth Pennisi | Aug 6, 1989 | 8 min read
Until six months ago or so, ecologist H. Ronald Pulliam never bothered with fax machines. Now his work depends on them. Every day he and 20 colleagues use the machines to iron out the details of a multimillion-dollar, multidisciplinary, multi-university proposal to study how plants interact with the atmosphere. But fax machines aren't the only things that have changed the way Pulliam, director of the Institute on Ecology at the University of Georgia, carries out his work on global change. Indeed
