Scientists work to deep-six carbon dioxide
02-07-2007 · Massachusetts Institute of Technology (MIT)A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the ground, where it would be trapped naturally as tiny bubbles and safely stored in briny porous rock.

- When bivalves ruled the world
08-31-2007 · EurekAlert!
Fraiser's work supports a relatively new theory for the cause of the massive extinction that occurred as the Permian period ended and the Triassic period began: toxic oceans created by too much atmospheric carbon dioxide. The theory is important because it could help scientists predict what would happen in the oceans during a modern "C02 event."

- Variable light illuminates the distribution of picophytoplankton
12-18-2007 · EurekAlert!
Tiny photosynthetic plankton less than a millionth of a millimeter in diameter numerically dominate marine phytoplankton. Their photosynthesis uses light to drive carbon dioxide uptake, fueling the marine food web over vast areas of the oceans. A new study published in this week's PLoS ONE by postdoctoral researcher Dr. Christophe Six and a team of scientists from MountAllison University, Sackville, New Brunswick, Canada, illuminates how the environment regulates the distributions of these ecologically important species.

- Ecologists, material scientists pursue genetics of diatom's elegant, etched casing
01-23-2008 · EurekAlert!
Scientists have discovered of whole subsets of genes and proteins that govern how one species of diatom builds its shell. For oceanographers, the work might one day help them understand how thousands of different kinds of diatoms -- and their ability to remove carbon dioxide from the atmosphere -- might be affected by something like global climate change.

09-21-2007 · Massachusetts Institute of Technology (MIT)
An MIT-led team of scientists has found that the southern pole of Mars contains the largest deposit of frozen water in the inner solar system, outside of Earth. The work shows that water, not carbon dioxide, is the predominant frozen liquid in that area.

- Carbon dioxide emissions predicted to reduce density of Earth's outermost atmosphere by 2017
12-11-2006 · EurekAlert!
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017, according to a team of scientists from the National Center for Atmospheric Research and Pennsylvania State University.

- Carbon dioxide and the ocean
03-07-2007 · EurekAlert!
Global increases in temperature are just one facet of a much larger issue that scientists at the Rosenstiel School of Marine and Atmospheric Science are dedicated to uncovering. "The Marine Inorganic Carbon Cycle," a paper recently published in the journal Chemical Reviews, attempts to quantify over 60 years of research, reviewing a vast array of science that brings into question the Earth’s natural ability to rebound from the increase in inorganic carbon dioxide in the atmosphere and oceans.

- New developments in 'artificial photosynthesis'
03-27-2007 · EurekAlert!
Scientists at Brookhaven National Laboratory are trying to design catalysts inspired by photosynthesis, the process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a system that can produce methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy. Four Brookhaven chemists will discuss their research on this "artificial photosynthesis" at the 233rd National Meeting of the American Chemical Society.

- Acid oceans warning
10-16-2007 · EurekAlert!
The world's oceans are becoming more acid, with potentially devastating consequences for corals and the marine organisms that build reefs and provide much of the Earth's breathable oxygen. The acidity is caused by the gradual buildup of carbon dioxide in the atmosphere, dissolving into the oceans. Scientists fear it could be lethal for animals with chalky skeletons which make up more than a third of the planet's marine life.

- Climate swings have brought great CO2 pulses up from the deep sea
05-11-2007 · EurekAlert!
A study released provides some of the first solid evidence that warming-induced changes in ocean circulation at the end of the last Ice Age caused vast quantities of ancient carbon dioxide to belch from the deep sea into the atmosphere.

11-22-2006 · EurekAlert!
Researchers at NIST and the University of Colorado at Boulder have designed a prototype carbon nanotube "knife" that would work like a tight-wire cheese slicer for cutting cells, allowing scientists to study them more precisely than they can today.
