Stomach ulcer not only aches, it also fluoresce. Russian researchers believe that the brighter the fluorescence is, the less chances the patient has to do without the operation.
Specialists of the Moscow Regional Scientific-Research Clinical Institute “MONIKI” named after M.F. Vladimirsky and the Chair of Biophysics, Russian State Medical University, have developed a fiber-optic spectrum analyzer that allows to measure intensity of fluorescence from the surface of the gastrointestinal tract ulcers in the course of laser therapy. Fluorescence intensity allows to foresee how successful the treatment would be and to select the most optimal irradiation conditions.
About 40 years ago, low intensity laser irradiation started to be applied for inflammatory diseases therapy. Multiple diseases are accompanied by increase of content of complex organic molecules – porphyrins – in the cells. These molecules are extremely sensitive to the red component of spectrum, therefore, the tissues with high content of porphyrins become targets to laser irradiation, which, in its turn, activates defense functions and the cell division process.

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...
