Washington State University researchers findings could help crops fend off disease
Scientists at Washington State University in Pullman have discovered a molecule that plays a role in the battle plants must win against bacteria and fungi that would eat them for lunch. The group led by Professor Clarence A. "Bud" Ryan isolated a small protein called Pep1 that appears to act like a hormone, signaling to the rest of the plant to raise its defenses at the first sign of an infection. They also discovered the receptor protein to which Pep1 binds to exert its protective effects.
Pep1 was isolated from the plant Arabidopsis thaliana, which is a species favored by investigators for attributes that facilitate experimentation, but the same molecule is found in crop species such as canola, soybean, potato, tomato, rice, and poplar. Therefore, further work on Pep1 and its receptor could lead to a general increase in the resistance of crops to pathogens, which could greatly benefit farmers. Already, the researchers have used the Pep1 gene to increase the resistance of Arabidopsis plants to a fungal pathogen called Pythium irregulare.

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...

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...
