These questions will be discussed during the international “Open Science Conference on Climate Extremes and Biogeochemical Cycles in the Terrestrial Biosphere: impacts and feedbacks across scales” in Seefeld, Austria, from 2nd to 5th April 2013, hosted by the University of Innsbruck.

More than 150 scientists from over 20 different countries will meet to discuss the responses of ecosystems to climate variability and weather extremes, based on experimental evidence and modeling of the biosphere-climate system.Rising atmospheric greenhouse gas concentrations not only lead to global warming but also to increased climate variability and extreme weather situations. Within the past decade an exceptionally high number of extreme heat waves occurred around the globe: Record breaking temperatures hit central Western Europe in 2003, causing a large number of fatalities due to heat stress. In South-Eastern Europe dramatic wildfires ravaged in 2007, especially in Greece. Together with huge forest fires, an extraordinary heat wave with record temperatures led to a high and long-lasting air pollution in western Russia in 2010. The drought in 2011-2012 was reported to be one of the most severe ever recorded in the United States, with an economic loss of billions of dollars and heavy crop failures.

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...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
