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."

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion
Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
