Not long ago, the biochemist’s main tool was a chromatograph or an electrophoresis plant, but now specialists in bio-informatics use special software to simulate biochemical processes and the behaviour of complex molecules.
This approach was used to research factitious proteins of the cytochrome P450 family by researchers from the V.N. Orekhovich Research Institute of Biomedical Chemistry, Russian Academy of Medical Sciences, guided by A.V. Lisitsa, Ph.D. (Biology), and their colleagues from Vanderbilt University (USA) guided by Doctor Larisa Podust. The project has been sponsored by Rosnauka and the CRDF foundation.
Proteins of this family play an important role in the organism: they are responsible for oxidation of xenobiotics – alien chemical compounds harmful to cells. Oxidation assists in removing xenobiotics from the organism, providing for cells’ purification from chemical skimming. The primary importance of cytochromes P450 resulted in the fact that these proteins are found practically in all existing organisms – in bacteria, plants, fungi and animals. Preserving general function universality, cytochromes P450 show great diversity in their structural organization.

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...
