Microstructural and biochemical characterization of the nanoporous sucker rings from Dosidicus gigas
Recent interest in the development of environmentally benign routes to the synthesis of novel multifunctional materials has resulted in numerous investigations into structure-function relationships of a wide range of ...
Rediscovery of the nucleolinus, a dynamic RNA-rich organelle associated with the nucleolus, spindle, and centrosomes
The nucleolinus is an RNA-rich compartment, closely apposed to or embedded within the nucleolus. Discovered over 150 years ago, fewer than two dozen articles have been published on the nucleolinus, probably because complex ...
Self-recognition and Ca2+-dependent carbohydrate–carbohydrate cell adhesion provide clues to the Cambrian explosion
The Cambrian explosion of life was a relatively short period ca. 540 million years ago that marked a generalized acceleration in the evolution of most animal phyla, but the trigger of this key biological event remains ...
Diverse styles of submarine venting on the ultraslow spreading Mid-Cayman Rise
Thirty years after the first discovery of high-temperature submarine venting, the vast majority of the global Mid Ocean Ridge remains unexplored for hydrothermal activity. Of particular interest are the world’s ultra-slow ...
Exploring microbial diversity and taxonomy using SSU rRNA hypervariable tag sequencing
(Public Library of Science, 2008-11-21)
Massively parallel pyrosequencing of hypervariable regions from small subunit ribosomal RNA (SSU rRNA) genes can sample a microbial community two or three orders of magnitude more deeply per dollar and per hour than capillary ...
International Carbon Coordination : Roger Revelle’s legacy in the Intergovernmental Oceanographic Commission
(Oceanography Society, 2010-09)
Since its inception in 1960, the Intergovernmental Oceanographic Commission (IOC) has been responsible for organizing and coordinating the scientific investigation of ocean carbon. Roger Revelle (Scripps Institution of ...
Future effects of ozone on carbon sequestration and climate change policy using a global biogeochemical model
Exposure of plants to ozone inhibits photosynthesis and therefore reduces vegetation production and carbon sequestration. The reduced carbon storage would then require further reductions in fossil fuel emissions to meet ...

Corrigendum: Sokolov, A., and Coauthors, 2009: Probabilistic forecast for twenty-first-century climate based on uncertainties in emissions (without policy) and climate parameters. J. Climate, 22, 5175–5204.
Methane fluxes between terrestrial ecosystems and the atmosphere at northern high latitudes during the past century : a retrospective analysis with a process-based biogeochemistry model
(American Geophysical Union, 2008-08-18)
We develop and use a new version of the Terrestrial Ecosystem Model (TEM) to study how rates of methane (CH4) emissions and consumption in high-latitude soils of the Northern Hemisphere have changed over the past century ...
Microtubule plus-end dynamics in Xenopus egg extract spindles
(American Society for Cell Biology, 2004-02-06)
Microtubule dynamics underlie spindle assembly, yet we do not know how the spindle environment affects these dynamics. We developed methods for measuring two key parameters of microtubule plus-end dynamic instability in ...
