Tennessine is a synthetic chemical element; it has symbolTs and atomic number 117. It has the second-highest atomic number and joint-highest atomic mass of all known elements and is the penultimate element of the 7th period of the periodic table. It is named after the U.S. state of Tennessee, where key research institutions involved in its discovery are located (however, the IUPAC says that the element is named after the "region of Tennessee").
The discovery of tennessine was officially announced in Dubna, Russia, by a Russian–American collaboration in April 2010, which makes it the most recently discovered element. One of its daughter isotopes was created directly in 2011, partially confirming the results of the experiment. The experiment itself was repeated successfully by the same collaboration in 2012 and by a joint German–American team in May 2014. In December 2015, the Joint Working Party of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP), which evaluates claims of discovery of new elements, recognized the element and assigned the priority to the Russian–American team. In June 2016, the IUPAC published a declaration stating that the discoverers had suggested the name tennessine, a name which was officially adopted in November 2016. (Full article...)
The terrain complicated battle tactics for both sides, but the Russians and the Austrians, having arrived in the area first, were able to overcome many of its difficulties by strengthening a causeway between two small ponds. They had also devised a solution to Frederick's deadly modus operandi, the oblique order. Although Frederick's troops initially gained the upper hand in the battle, his limited scouting, combined with the strong defensive preparations of the Allied troops, gave the Russians and Austrians an advantage. By afternoon, when the combatants were exhausted, fresh Austrian troops thrown into the fray secured the Allied victory. (Full article...)

With the pale yellow rump visible. Buryatia, Russia.
Pallas's leaf warbler is one of the smallest Palearcticwarblers, with a relatively large head and short tail. It has greenish upperparts and white underparts, a lemon-yellow rump, and yellow double wingbars, supercilia and central crown stripe. It is similar in appearance to several other Asian warblers, including some that were formerly considered to be subspecies of it, although its distinctive vocalisations aid identification.

Viatkogorgon is a genus of gorgonopsian (a type of therapsid, the group that includes modern mammals) that lived during the Permian period in what is now Russia. The first fossil was found at the Kotelnich locality near the Vyatka River and was made the holotype of the new genus and speciesV. ivachnenkoi in 1999. The generic name refers to the river and the related genus Gorgonops—the gorgons of Greek mythology are often referenced in the names of the group. The specific name honors the paleontologist Mikhail F. Ivakhnenko. The holotype skeleton is one of the most complete gorgonopsian specimens known and includes rarely preserved elements such as gastralia (abdominal ribs) and a sclerotic ring (a bony ring inside the eye). A larger, but poorly preserved specimen has also been assigned to the species.
The holotype specimen is about 80 cm (31 in) long, including the 14 cm (5.5 in) long skull, making Viatkogorgon a relatively small gorgonopsian. The assigned specimen is larger, with a 17 cm (6.7 in) long skull, and the holotype may have been young. As a gorgonopsian, it would have been skeletally robust with a somewhat dog-like stance, though with outwards-turned elbows. The snout was high, and the teeth were generally recurved (curved backward), pointed, and serrated. The canines (the saber teeth) were much larger than the incisors at the front and postcanines behind but relatively small for a gorgonopsian. Viatkogorgon was characterized by its unusually large eye socket and sclerotic ring. It was distinct from other gorgonopsians in that the lower end of the postorbital bar was narrow, and it had a very large sulcus (or furrow) at the back of the skull on each side. Since gorgonopsians have been described mainly from skulls, it is uncertain how widespread the postcranial features of Viatkogorgon were in other members of the group. The skeleton of Viatkogorgon was unusual in having gastralia, in that the tail was differentiated with a front and hind part, with the former less flexible, and in that some of the foot bones and its digits were reduced in size and interconnected.

Khrushchev was born in 1894 in a village in western Russia. He was employed as a metal worker during his youth, and he was a political commissar during the Russian Civil War. Under the sponsorship of Lazar Kaganovich, Khrushchev worked his way up the Soviet hierarchy. He originally supported Stalin's purges and approved thousands of arrests. In 1938, Stalin sent him to govern the Ukrainian SSR, and he continued the purges there. During what was known as the Great Patriotic War, Khrushchev was again a commissar, serving as an intermediary between Stalin and his generals. Khrushchev was present at the defense of Stalingrad, a fact he took great pride in. After the war, he returned to Ukraine before being recalled to Moscow as one of Stalin's close advisers.

Nadezhda Sergeyevna Alliluyeva (Russian: Надежда Сергеевна Аллилуева; 22 September [O.S. 9 September] 1901 – 9 November 1932) was the second wife of Joseph Stalin. She was born in Baku to a friend of Stalin, a fellow revolutionary, and was raised in Saint Petersburg. Having known Stalin from a young age, she married him when she was 17, and they had two children. Alliluyeva worked as a secretary for Bolshevik leaders, including Vladimir Lenin and Stalin, before enrolling at the Industrial Academy in Moscow to study synthetic fibres and become an engineer. She had health issues, which had an adverse impact on her relationship with Stalin. She also suspected he was unfaithful, which led to frequent arguments with him. On several occasions, Alliluyeva reportedly contemplated leaving Stalin, and after an argument, she fatally shot herself early in the morning of 9 November 1932. (Full article...)
Dubnium does not occur naturally on Earth and is produced artificially. The Soviet Joint Institute for Nuclear Research (JINR) claimed the first discovery of the element in 1968, followed by the American Lawrence Berkeley Laboratory in 1970. Both teams proposed their names for the new element and used them without formal approval. The long-standing dispute was resolved in 1993 by an official investigation of the discovery claims by the Transfermium Working Group, formed by the International Union of Pure and Applied Chemistry and the International Union of Pure and Applied Physics, resulting in credit for the discovery being officially shared between both teams. The element was formally named dubnium in 1997 after the town of Dubna, the site of the JINR. (Full article...)

Stravinsky in the early 1920s
Igor Fyodorovich Stravinsky (17 June [O.S. 5 June] 1882 – 6 April 1971) was a Russian composer and conductor with French citizenship (from 1934) and American citizenship (from 1945). He is widely considered one of the most important and influential composers of the 20th century and a pivotal figure in modernist music.
The Shuttle–Mir program (Russian: Программа «Мир»–«Шаттл») was a collaborative space program between Russia and the United States that involved American Space Shuttles visiting the Russian space stationMir, Russian cosmonauts flying on the Shuttle, and an American astronaut flying aboard a Soyuz spacecraft to allow American astronauts to engage in long-duration expeditions aboard Mir.
The project, sometimes called "Phase One", was intended to allow the United States to learn from Russian experience with long-duration spaceflight and to foster a spirit of cooperation between the two nations and their space agencies, the National Aeronautics and Space Administration (NASA) and the Russian Space Agency (PKA). The project helped to prepare the way for further cooperative space ventures; specifically, "Phase Two" of the joint project, the construction of the International Space Station (ISS). The program was announced in 1993, the first mission started in 1994 and the project continued until its scheduled completion in 1998. Eleven Space Shuttle missions, a joint Soyuz flight and almost 1,000 cumulative days in space for American astronauts occurred over the course of seven long-duration expeditions. In addition to Space Shuttle launches to Mir the United States also fully funded and equipped with scientific equipment the Spektr module (launched in 1995) and the Priroda module (launched in 1996), making them de facto U.S. modules during the duration of the Shuttle-Mir program.

The army was formed at Khabarovsk in the Soviet Far East in 1938 as the 2nd Army. After the Far Eastern Front was split in September that year it became the 2nd Independent Red Banner Army. When the front was reformed in June 1940, the army was redesignated as the 2nd Red Banner Army, stationed in the Blagoveshchensk area. It spent the bulk of World War II guarding the border in that area, sending formations to the Eastern Front while undergoing several reorganizations. In August 1945, the army fought in the Soviet invasion of Manchuria, capturing the Japanese fortified regions of Aihun and Sunwu adjacent to its sector of the border, and advancing into Manchuria to Qiqihar. The army was disbanded after the war in late 1945. (Full article...)
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as adult females are much smaller. The polar bear is white- or yellowish-furred with black skin and a thick layer of fat. It is more slender than the brown bear, with a narrower skull, longer neck and lower shoulder hump. Its teeth are sharper and more adapted to cutting meat. The paws are large and allow the bear to walk on ice and paddle in the water.
Polar bears are both terrestrial and pagophilic (ice-living) and are considered marine mammals because of their dependence on marine ecosystems. They prefer the annual sea ice but live on land when the ice melts in the summer. They are mostly carnivorous and specialized for preying on seals, particularly ringed seals. Such prey is typically taken by ambush; the bear may stalk its prey on the ice or in the water, but also will stay at a breathing hole or ice edge to wait for prey to swim by. The bear primarily feeds on the seal's energy-rich blubber. Other prey include walruses, beluga whales and some terrestrial animals. Polar bears are usually solitary but can be found in groups when on land. During the breeding season, male bears guard females and defend them from rivals. Mothers give birth to cubs in maternity dens during the winter. Young stay with their mother for up to two and a half years. (Full article...)

A Finnish Maxim M/09-21 machine gun crew during the Winter War
The Winter War was a war between the Soviet Union and Finland. It began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940. Despite superior military strength, especially in tanks and aircraft, the Soviet Union suffered severe losses and initially made little headway. The League of Nations deemed the attack illegal and expelled the Soviet Union from its organization.
The Soviets made several demands, including that Finland cede substantial border territories in exchange for land elsewhere, claiming security reasons – primarily the protection of Leningrad, 32 km (20 mi) from the Finnish border. When Finland refused, the Soviets invaded. Most sources conclude that the Soviet Union had intended to conquer all of Finland, and cite the establishment of the puppet Finnish Communist government and the Molotov–Ribbentrop Pact's secret protocols as evidence of this, while other sources argue against the idea of a full Soviet conquest. Finland repelled Soviet attacks for more than two months and inflicted substantial losses on the invaders in temperatures as low as −43 °C (−45 °F). The battles focused mainly on Taipale along the Karelian Isthmus, on Kollaa in Ladoga Karelia and on Raate Road in Kainuu, but there were also battles in Salla and Petsamo in Lapland.

Manuel I Komnenos (Greek: Μανουήλ Κομνηνός, romanized: Manouḗl Komnēnós; 28 November 1118 – 24 September 1180), Latinized as Comnenus, also called Porphyrogenitus (Greek: Πορφυρογέννητος; "born in the purple"), was a Byzantine emperor of the 12th century who reigned over a crucial turning point in the history of Byzantium and the Mediterranean. His reign saw the last flowering of the Komnenian restoration, during which the Byzantine Empire experienced a resurgence of military and economic power and enjoyed a cultural revival.
Eager to restore his empire to its past glories as the great power of the Mediterranean world, Manuel pursued an energetic and ambitious foreign policy. In the process he made alliances with Pope Adrian IV and the resurgent West. He invaded the Norman Kingdom of Sicily, although unsuccessfully, being the last Eastern Roman emperor to attempt reconquests in the western Mediterranean. The passage of the potentially dangerous Second Crusade through his empire was adroitly managed. Manuel established a Byzantine protectorate over the Crusader states of Outremer. Facing Muslim advances in the Holy Land, he made common cause with the Kingdom of Jerusalem and participated in a combined invasion of FatimidEgypt. Manuel reshaped the political maps of the Balkans and the eastern Mediterranean, placing the kingdoms of Hungary and Outremer under Byzantine hegemony and campaigning aggressively against his neighbours both in the west and in the east.

On 6 August 1945, at 8:15 am local time, the United States detonated an atomic bomb over the Japanese city of Hiroshima. Sixteen hours later, American President Harry S. Truman called again for Japan's surrender, warning them to "expect a rain of ruin from the air, the like of which has never been seen on this earth." Late on 8 August 1945, in accordance with the Yalta agreements, but in violation of the Soviet–Japanese Neutrality Pact, the Soviet Union declared war on Japan, and soon after midnight on 9 August 1945, the Soviet Union invaded the Japanese puppet state of Manchukuo. Hours later, the United States dropped a second atomic bomb, on the Japanese city of Nagasaki. Emperor Hirohito ordered the Supreme Council for the Direction of the War to accept the terms the Allies had set down in the Potsdam Declaration. After several more days of behind-the-scenes negotiations and a failed coup d'état, Emperor Hirohito gave a recorded radio address across the Empire on 15 August announcing the surrender of Japan to the Allies.

This photo of the Nilov Monastery on Stolobny Island in Tver Oblast, Russia, was taken by Sergey Prokudin-Gorsky in 1910 before the advent of colour photography. His process used a camera that took a series of monochrome pictures in rapid sequence, each through a different coloured filter. By projecting all three monochrome pictures using correctly coloured light, it was possible to reconstruct the original colour scene.
Leo Tolstoy (1828–1910) was a Russian writer who is regarded as one of the world's greatest novelists. He is best known for War and Peace (1869) and Anna Karenina (1877), often cited as pinnacles of realist fiction. Born to an aristocratic family on 9 September [O.S. 28 August] 1828, Tolstoy was orphaned when he was young. He studied at Kazan University, but this was not a success, and he left university without completing his degree. During this time, he began to write and published his first novel, Childhood, in 1852. Tolstoy later served at the Siege of Sevastopol during the Crimean War, and was appalled by the number of deaths and left at the conclusion of the war. He spent the remainder of his life writing whilst also marrying and starting a family. In the 1870s he converted to a form of fervent Christian anarchism.
Saint Basil's Cathedral is a church in Red Square in Moscow, Russia. It was built from 1555 to 1561 on orders from Ivan the Terrible and commemorates the capture of Kazan and Astrakhan. The city's tallest building until the completion of the Ivan the Great Bell Tower in 1600, the original building contained eight side churches arranged around the ninth, central church of Intercession; the tenth church was erected in 1588 over the grave of venerated local saint Vasily (Basil). Although the Bolsheviks considered demolishing the church in the 1930s, it was spared. Since 1991 it has housed a branch of the State Historical Museum and hosted occasional church services.
Hotel Astoria is a five-star hotel located on Saint Isaac's Square in Saint Petersburg. Commissioned in 1910 by the Palace Hotel Company to host visitors to the Romanov tercentenary, the hotel was designed by Fyodor Lidval and first opened in 1912. After the October Revolution, it continued to be used as a state-operated hotel, though during World War II it was also a field hospital. The hotel, now owned by Rocco Forte Hotels, has been renovated several times, most recently in 2012.

Although James Clerk Maxwell made the first color photograph in 1861, the results were far from realistic until Prokudin-Gorsky perfected the technique with a series of improvements around 1905. His process used a camera that took a series of monochrome pictures in rapid sequence, each through a different colored filter. Prokudin-Gorskii then went on to document much of the country of Russia, travelling by train in a specially equipped darkroomrailroad car.
The Tauride Palace is one of the largest and most historic palaces in Saint Petersburg, Russia. It was designed by Ivan Starov for Prince Grigory Potemkin, and was constructed between 1783 and 1789. After the owner's death, it was purchased by Catherine the Great, who constructed a theatre in the east wing and a church in the west wing. Many improvements were also made to the grounds, including construction of the Admiralty Pavilion, the gardener house, the orangery, glass-houses, bridges, and ironwork fences. Although the exterior of the building was rather plain, the interior was very luxurious. More recently, the building housed the first Imperial State Duma (1906–1917) and the post-revolution provisional government.
Kombat (Russian for 'battalion commander') is a black-and-white photograph by Soviet photographer Max Alpert. It depicts a Soviet military officer, armed with a TT pistol, raising his unit for an attack during World War II. This work is regarded as one of the most iconic Soviet World War II photographs, yet neither the date nor the subject is known with certainty. According to the most widely accepted version, it depicts junior politruk Aleksei Gordeyevich Yeryomenko, minutes before his death on 12 July 1942, in Voroshilovgrad Oblast, now part of Ukraine. The photograph is in the archives of RIA Novosti, a Russian state-owned news agency.

Born and raised in Georgia, in the Russian Empire, Ordzhonikidze joined the Bolsheviks at an early age and quickly rose within the ranks to become an important figure within the group. Arrested and imprisoned several times by the Russian police, he was in Siberian exile when the February Revolution began in 1917. Returning from exile, Ordzhonikidze took part in the October Revolution that brought the Bolsheviks to power. During the subsequent Civil War he played an active role as the leading Bolshevik in the Caucasus, overseeing the invasions of Azerbaijan, Armenia, and Georgia. He backed their union into the Transcaucasian Socialist Federative Soviet Republic (TSFSR), which helped form the Soviet Union in 1922 and served as the First Secretary of the TSFSR until 1926.
