Special section in journal details new studies
Five articles published in a Special Section in the December 2004 issue of BioScience, the monthly journal of the American Institute of Biological Sciences (AIBS), provide new global assessments of how well protected areas such as parks can safeguard the numerous animal and plant species at risk of becoming extinct. The new analyses lead to the conclusion that although nominally protected areas now approach 12 per cent of the Earths land surface, more needs to be done. The studies point to regions that should have high priority in the creation of additional protected areas for biodiversity conservation, and suggest ways to identify specific sites.
The articles employ the framework known as gap analysis, a planning approach based on the assessment of the comprehensiveness of existing protected-area networks and the identification of "gaps" in coverage--species whose distribution means they are nowhere protected.

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...
