Since passage of the Endangered Species Act in 1973, over 1,300 endangered species have been protected in the United States and its territories. In the forthcoming issue of Ecology Letters, Male & Bean assess 14 years of endangered plant and animal status trends and show that the length of time species are protected, and the amount of money spent on their conservation are key variables in explaining trends.
Overall, about half of species protected are no longer declining and only 35 % of species protected for 13 years or more were still declining. Status trends are partly explained by taxonomy and funding. Species reported as receiving more money from the U.S. Fish and Wildlife Service or National Oceanic and Atmospheric Administration were much more likely to be improving or stable than those receiving less funding.
This study emphasizes the need to consider the ways in which agencies administer and the U.S. Congress funds the Endangered Species Act in judging whether the law is a success or failure in recovering biodiversity. This issue has become a major focus of political battles over this controversial environmental law.

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...
