Interesting facts have been discovered in phytoimmunity sphere by the Russian-Belorus group of biochemists in the framework of the Russian Foundation for Basic Research and Belorus Foundation for Basic Research projects. To protect themselves from pathogenic fungi, which penetrate plant tissues with the help of proteinase proteins, vegetables produce inhibitors to these proteinases. A peculiar “arms race” is taking place between them.
Animals’ immune system cells are aimed at resistance within the organism but phytoimmunity is mainly based on preventing the pathogen from “drilling a hole” in the integuments and defending itself from a vegetable antibiotic. Fungi penetrate plant tissues with the help of proteinase enzymes which decompose proteins of cellular walls and antimicrobial proteins.
Researchers have assumed that a plant organism should produce appropriate inhibitors to protect itself from these enzymes.

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...
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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
