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.

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.
Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.
In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...
In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.
Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
