"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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
