Russian archaeologists have discovered in the Leningrad region a medieval treasure weighing more than two kilograms, consisting of silver items from the 10th to 14th centuries, including medallions, a hryvnia, coins and jewelry. The find was made at the Tiversky town monument and, according to preliminary estimates, is the richest treasure of this period in the North-West of Russia.

RAS President Gennady Krasnikov said that islands appear and disappear on Earth due to volcanic activity and earthquakes. Since 2015, more than 15 new islands have been discovered in the Arctic, and the sea plains and depths of Russia are still underexplored.

A medieval treasure with silver items from the 10th to 14th centuries was found in the Leningrad region, which is the largest in the history of Russian archeology from similar finds of this period in the North-West of Russia. The treasure includes round medallions, a hryvnia, coin pendants, a Karelian-type head adornment, silver chains, a ring, a fibula, a leather necklace and three coins, including an Arab dirham from 907–912 and unique Uppsala-type bracteates made in Sweden. Among the finds is a medallion with an image possibly related to Scandinavian mythology (Odin's ravens Hugin and Munin and the spear Gungnir), which creates a mystery due to its proximity to Christian symbolism. The weight of the treasure exceeds two kilograms. Specialists from the Museum of Anthropology and Ethnography of the Russian Academy of Sciences (Kunstkamera) and the St. Petersburg Research Center “Actual Archeology” participated in the excavations.

Scientists at the Institute of Automation and Control Processes of the Far Eastern Branch of the Russian Academy of Sciences are developing a “laboratory on a chip” to analyze the biochemical composition of blood in real time using induced photoluminescence and a plasma signal amplification system, which will allow diagnostics with a minimum volume of blood, potentially even through a smartphone.

Scientists at the Karpinsky Institute explained that volcano-hydrothermal systems contribute to the formation of deposits of gold, silver, copper and other metals. Examples of such deposits are given from Russia (Okhotsk-Chukotka belt, Kupol and Dukat fields), Indonesia (Grasberg) and Mongolia (Oyu Tolgoi).
