Scientists of Tyumen presented material for road construction in the Arctic

The construction of roads in the harsh Arctic conditions — not an easy task. But scientists from the Tyumen industrial University (TIU), together with colleagues from the Institute of the Earth cryosphere of the Siberian branch of the RAS has created a heat insulating material made from natural raw materials, which will be able to cope with the main problem arising in the construction of roads, — the increase in volume of soil due to freezing of contained moisture.

The fighters with combat lasers will go into service in 2021

New weapon systems for combat aircraft based on lasers have been developed for a long time. Even during the Cold War, the first attempts were made to create such aircraft. But only now, within the framework of the SHIELD (Self-protect High Energy Laser Demonstrator) program, funded by the US Air Force, Lockheed Martin will present the first samples of a powerful and yet compact laser weapon that can be installed on fighter planes by 2021.
