The U.S. Government is spending millions of dollars to research the feasibility of stuffing carbon dioxide into coal seams and fields of briny water deep beneath the Earth. But, a scientist at the American Association for the Advancement of Science (AAAS) Annual Meeting argues that the government isnt thinking big enough in its plans to remove carbon dioxide from the atmosphere.
Dissatisfied with the long-term potential of most current technologies for carbon sequestration, Klaus Lackner, Ewing-Worzel Professor of Geophysics at Columbia University, has designs for new power plants that would capture carbon dioxide before it leaves the facility, as well as for "synthetic trees" that would pluck carbon from the air, mix it with magnesium silicate, and store the carbon in the "rocks" that would result from the chemical interaction between the elements.
"Injecting carbon underground is a short-term solution," Lackner said. "The oil industry has done this with 20 million tons a year in West Texas, but that is not the scale were talking about here. We need to find a way to put away 20 billion tons." The Intergovernmental Panel on Climate Change has estimated that worldwide carbon dioxide emissions could more than triple over the next 100 years, from 7.4 billion tons of carbon per year in 1997 to approximately 20 billion tons per year by 2100. Lackner argued that large-scale carbon sequestration would allow the continued use of carbon-based fuels during the time needed to develop alternative sources of energy.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
