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.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
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...
