In 2002-2003, three expeditions involving specialists of the Institutes of Geochemistry, of Solar-Terrestrial Geophysics, and of the Earths Crust, Siberian Branch, Russian Academy of Sciences (Irkutsk) looked for traces of meteoroid that had fallen down in the north-east of the Irkutsk Province, in the Mamsko-Chuisk region. None of the expeditions found either craters or meteoroid fragments. Only fallen trees and minor particles of meteorite substance mark the direction of celestial body falling.
At night of September 25, 2002, inhabitants of the Mamsko-Chuisk and Bodaibinsk regions (Irkutsk Province) watched the flight of a bright bolide. Although the weather was bad, a lot of people distinctly saw the surgeless white bright fluorescence flaming up in the south-west. It filled up all the sky and then moved from the valley of the Vitim River to the north-eastern direction. The fluorescence turned from white to blue and then to redly vinous. The flight of meteoroid was accompanied by hollow rumble and completed with a blow and shaking of the earth.
The rumble and rustling heard by multiple natives may be connected with occurrence of electric wave in the atmosphere. The variable electric field was so strong that in the apartment houses of Mama settlement, which were cut off power supply at that time, incandescent lamps began to shine dimly. Seismic stations of the Irkutsk Province recorded only feeble local shaking. Bright fluorescence at the altitude of 62 kilometers was recorded by a US satellite which tracked the fluorescence down to the 30 kilometer altitude. The satellite identified the altitude and position data of two points, based on which the Russian scientists managed to reconstruct the meteorite’s trajectory and sent several expeditions in search of it.

Researchers explore ultrafast control of magnetism across interfaces: A new study discovers how the sudden excitation of lattice vibrations in a crystal can trigger a change of the magnetic properties of an atomically-thin layer that lies on its surface.

Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.
The Juncal Viaduct, in Gran Canaria, has served as a reference for Spanish and British researchers to verify that the wind blowing between the pillars on this...
