Probabilistic forecast for twenty-first-century climate based on uncertainties in emissions (without policy) and climate parameters
(American Meteorological Society, 2009-10-01)
The Massachusetts Institute of Technology (MIT) Integrated Global System Model is used to make probabilistic projections of climate change from 1861 to 2100. Since the model’s first projections were published in 2003, ...
Consequences of considering carbon–nitrogen interactions on the feedbacks between climate and the terrestrial carbon cycle
(American Meteorological Society, 2008-08-01)
The impact of carbon–nitrogen dynamics in terrestrial ecosystems on the interaction between the carbon cycle and climate is studied using an earth system model of intermediate complexity, the MIT Integrated Global Systems ...

Roles of polymerization dynamics, opposed motors, and a tensile element in governing the length of Xenopus extract meiotic spindles
(American Society for Cell Biology, 2005-03-23)
Metaphase spindles assemble to a steady state in length by mechanisms that involve microtubule dynamics and motor proteins, but they are incompletely understood. We found that Xenopus extract spindles recapitulate the ...
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 ...
Effects of tropospheric ozone pollution on net primary productivity and carbon storage in terrestrial ecosystems of China
(American Geophysical Union, 2007-11-17)
We investigated the potential effects of elevated ozone (O3) along with climate variability, increasing CO2, and land use change on net primary productivity (NPP) and carbon storage in China's terrestrial ecosystems for ...
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 ...
A novel 65 kDa RNA-binding protein in squid presynaptic terminals
A polyclonal antibody (C4), raised against the head domain of chicken myosin Va, reacted strongly towards a 65 kDa polypeptide (p65) on western blots of extracts from squid optic lobes but did not recognize the heavy ...
Nutrient enrichment induces dormancy and decreases diversity of active bacteria in salt marsh sediments
(Nature Publishing Group, 2016-09-26)
Microorganisms control key biogeochemical pathways, thus changes in microbial diversity, community structure and activity can affect ecosystem response to environmental drivers. Understanding factors that control the ...
New insights into microbial ecology through subtle nucleotide variation
(Frontiers Media, 2016-08-24)
Characterizing the community structure of naturally occurring microbes through marker gene amplicons has gained widespread acceptance for profiling microbial populations. The 16S ribosomal RNA (rRNA) gene provides a suitable ...
