It involves gathering billions of tons of cornstalks, wheat straw, and other crop residue from farm fields, bailing it, shipping the material to seaports, and then burying it in the deep ocean.
Scientists in Washington and California have concluded that this Crop Residue Oceanic Permanent Sequestration (CROPS) approach is the only practical method now available for permanently sequestering, or isolating, the enormous quantities of CO2 necessary to have a real impact on global warming.
In a report scheduled for the Feb. 15 issue of ACS’ Environmental Science & Technology, a semi-monthly journal, Stuart Strand and Gregory Benford conclude that (CROPS) could reduce global carbon dioxide accumulation by up to 15 percent per year. Plants remove carbon dioxide from the atmosphere during photosynthesis, and release it when they decay. Ocean burial would prevent that carbon dioxide from re-entering the atmosphere.
After comparing known methods for carbon dioxide sequestration on the basis of efficiency, long-term effectiveness, practicality, and cost, the researchers concluded that CROPS is the only method feasible with existing technology. CROPS would be 92 percent efficient in sequestering crop residue carbon. They recommend that crop residue sequestration and its effects on the ocean should be investigated further and its implementation encouraged.ARTICLE #3

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
