"We should not count on carbon storage by land ecosystems to make a massive contribution to slowing climate change," said Dr. Christopher Field, director of the Department of Global Ecology at the Carnegie Institution. "And lower storage of carbon in these ecosystems results in a faster increase in atmospheric carbon dioxide, leading to more rapid global warming."
Future atmospheric levels of the notorious heat-trapping gas, carbon dioxide, remain a controversial topic among environmental scientists. Many researchers believe that increasing amounts of CO2, belched into the atmosphere by human fossil fuel use, will be captured through nature’s ability to lock up the carbon in soil organic matter and faster growing trees. But it’s not so simple. A new report, published in the November 28 Science, shows that the availability of nitrogen, in forms usable by plants, will probably be too low for large increases in carbon storage.
Ecosystems on land can store carbon, through bigger trees and more organic matter in soils, but shortages of mineral nutrients, especially nitrogen, curb potential future carbon storage. Several approaches to calculating ecosystem carbon storage, including some featured in the Third Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) assume that nitrogen available to plants is abundant, even though current nitrogen limitation is widespread. "Realistic scenarios for future changes in nitrogen availability limit ecosystem carbon storage to the low end of the range presented in the recent IPCC report," says Field.

Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.
The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.
Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
