Today the European Commission presented the latest results of the EU-funded EPICA (European Ice Core Project in Antarctica) initiative. Scientists from 10 European countries including Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway, Sweden, Switzerland, and the UK have dug 3 kilometres-deep into the Antarctic ice crust and brought to the surface a 740, 000-year old ice core. It is the oldest ever analysed and records climate history. It shows changes in temperature and concentrations of gases and particles in the atmosphere. The results will feed into computer models used to predict future climate. Preliminary results show that, without human influence, the present “warm season” in Earth’s climate could last for 15 000 years more. But since the present carbon dioxide concentration is the highest in the last 440,000 years, by understanding past changes in climate, it will be possible to forecast future climate change due to human activities. Further results of the EPICA project will be disclosed at the “Palaeoclimate Conference: Reducing the Uncertainties” in Utrecht, the Netherlands, on July 6-10, 2004.
European Research Commissioner Philippe Busquin said: “I am proud to see that EU research is at the forefront of climate change research. Thanks to the EU’s research programmes, European scientists are able to work together and be at the cutting edge of science, in climate change research as in other fields. When European researchers work together, they are the best.”

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
