Despite dozens of interceptions at U.S. ports, a public enemy has infiltrated the nations borders. Taken captive in Fulton County, N.Y., and identified by a Cornell University expert, the adult female alien is the only one of its kind ever discovered in the eastern United States.
The discovery of a single specimen of Sirex noctilio Fabricius, an Old World woodwasp, raises red flags across the nation because the invasive insect species has devastated up to 80 percent of pine trees in areas of New Zealand, Australia, South America and South Africa. If established in the United States, it would threaten pines coast-to-coast, particularly in the pine-dense states in the Southeast. One target would be loblolly pines in Georgia.
Finding one bug in a trap is no small matter. Where theres one, theres likely to be more, says E. Richard Hoebeke, a Cornell senior extension associate in entomology. "Whenever you find an insect in a trap, it probably is established."

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...
