Voter turnout in Germany is decreasing as it is in many established democracies. At the same time other modes of participation in politics are increasing. This combination is detrimental to the democratic ideal of political equality because elections are less socially skewed than other types of political participation. more
Residential broadband ISPs like DSL & cable are being used by hundreds of millions of people to access the Internet. Today, ISPs are deploying firewalls and traffic shapers to manipulate the performance of user traffic. Most ISPs do not reveal the details of their networks to their customers, preventing them from making an informed choice of their ISP. The goal of our Glasnost project is to make access networks more transparent to their customers. To date, more than a hundred thousand users world-wide used Glasnost to test if their ISPs are interfering with their peer-to-peer traffic. more

Beyond the clouds: News from Venus

Max Planck Institute for Solar System Research Titov, Dimitri; Markiewicz, Wojciech; Fränz, Markus
After many years of exploration of planet Venus by sovjet and american spacecraft a large number of questions about history and structure of the planet and its atmosphere remained open. In 2005 the first European mission to planet Venus was launched: Venus Express – with a strong contribution by the MPI for Solar System Research. First analyses of the data received since 2006 show a previously unimagined structuring and dynamics of the cloud layers and allow new conclusions about the evolution of the atmosphere of Venus. more
Symmetries play an important role in science as well as in every day life. They are regarded as esthetic and they can be used to simplify problems. On the other hand, a reduction of symmetries may lead to the consequence that certain properties of a system become discernable. In the field of spintronics this is used to manipulate the electron spin without the use of magnetic fields. The design and characterization of nanostructures relevant for spintronics are studied in the Department of Prof. Kern and the Emmy-Noether-Research-Group "Electronic structure at surfaces and interfaces". more
Elementary properties of the recently discovered alkali-earth intercalated graphite compounds AC6 (A = Ca, Sr, Yb) will be described. These new superconductors with critical temperatures of up to 11.6 K can be described as electron-phonon coupled superconductors with a weakly anisotropic order parameter. Experimental results and ab-initio calculations are in good agreement. more
