Evolution of the Kulikovo Field lands illustrates how national stability and instability may change territories, including their landscape, utilization and land settlement. This conclusion has been made by O.V. Burova from the Tula State Teachers Training University named after L.N. Tolstoy, who has analyzed archaeological investigation materials for many years, archives data, results of comprehensive geographical and palaeogeographical investigations.
During the Bronze Age, forest-steppes of the Upper Don River were favorite locality of nomads and cattle-breeders. By the 12th century, favorable conditions for settled life were formed on the territories of the Upper Don River: princes came to an agreement with the Don nomadic tribes (polovtsy), and the situation in the region became calm and relatively stable.
These lands were colonized by the Slavs who introduced agricultural system, the agricultural landscape began to set up there, settlements appeared, their number growing. The settlement locations were disforested, but agricultural holdings were established with minimal disafforestation. Therefore, the first phase of developing Kulikovo Field was a delicate one and not disastrous for environment, the specialists are talking about formation of the local type of agricultural landscape.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
