Hurricanes bring temporary relief to Florida reefs smothered by invasive seaweed
In August, Harbor Branch scientists began a new survey of Florida coral reefs expecting to document the devastating spread of harmful seaweed that has been progressing now for several years, but hurricane havoc has instead led the team to a surprising find. With their first survey nearly completed, it appears all reefs in the path of hurricanes Frances and Jeanne have been largely scoured free of the menacing seaweed, and many have also been buried in sand. Seaweed overgrowth problems are likely to return, however, and could even be exacerbated by the storms temporary removal. Further south, off areas beyond the brunt of the storms, the team has found alarming concentrations of a cyanobacterium similar to algae killing corals and other reef organisms.
"This is uncharted territory," says Harbor Branch marine ecologist Brian Lapointe, "no one has ever had the chance to study the impacts of natural phenomena like hurricanes on reefs under siege from these harmful algal blooms that we believe are triggered by humans."

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

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...
