Moscow scientists have come forward with a new methodology of fighting fire, as fire can be stopped if deprived of airflow. It is possible that soon fire-wardens will extinguish fire not with water or foam, but with liquid nitrogen.
A bright-red fire-engine has been demonstrated at the exhibition ‘High tech-2004’, held at Krasnaya Presnya exhibition complex in Moscow. The engine was so huge, that inside its body it could accommodate a tank the size of a well-fed elephant. The tank contained neither water or foam, but liquid nitrogen. The idea to extinguish fire with the help of liquid nitrogen was brought forward by the Moscow scientists from ‘Granat’ State Unitary Enterprise, Special Design Office named after V.K. Orlov.
Sadly enough, when a fire occurs in a library, theatre or even in an apartment building, the material damage caused by it might be comparable to that caused by the process of fire extinguishing. Valuable manuscripts, theatre decor and costumes, computers, even ordinary clothes and furniture – all these things get destroyed in a fire, being damaged not only by the fire itself, but also by water, foam and in the course of other traditional methods of fire extinguishing.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
