The crucial role that Antarctica plays in global climate change and its future contribution to sea-level rise was highlighted today by Professor Chris Rapley, Director of British Antarctic Survey (BAS). Speaking at an international convention on climate change in Bonn, Germany* he presented a summary of the latest scientific results from Antarctica.
Professor Rapley said, “The issue of sea-level rise is of great concern to all of us – the contribution from Antarctica is the greatest uncertainty in the sea level rise debate. The last IPCC (Intergovernmental Panel on Climate Change - 2001) report warned that Antarctica was a ‘slumbering giant’. Recent scientific evidence leads us to believe that the giant is waking up. Policy-makers need to know what the consequences will be for society.”
Computer models suggest that the East Antarctic Ice Sheet may thicken as a result of climate change, but observations from satellites and aircraft show that two other areas are thinning. These conflicting effects and the challenge of measuring them make it difficult at present to predict the contribution of Antarctica to sea level rise, there is no doubt that its role will be significant.

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”.
