It is the world's seventh-most spoken language by number of native speakers , and

476-519: A new education law which requires all schools to teach at least partially in Ukrainian, with provisions while allow indigenous languages and languages of national minorities to be used alongside the national language. The law faced criticism from officials in Russia and Hungary. The 2019 Law of Ukraine "On protecting the functioning of the Ukrainian language as the state language" gives priority to

595-554: A contaminant that uses kerosene—the antifreeze used during drilling—as an energy source. Critics from the scientific community state that no valuable information can be obtained until they can test clean samples of lake water, uncontaminated by drilling fluid. Regardless of the contamination issues, in May 2013 the drilling facility at the Russian Vostok Antarctic station was declared a historic monument as "the result of

714-456: A continuous paleoclimatic record of 400,000 years, although the lake water itself may have been isolated for 15 to 25 million years. On 5 February 2012, a team of Russian scientists completed the longest ever ice core of 3,768 m (12,400 ft) and pierced the ice shield to the surface of the lake. The first core of freshly frozen lake ice was obtained on 10 January 2013 at a depth of 3,406 m (11,175 ft). However, as soon as

This allows echoes from

952-491: A geothermal system of the bedrock encircling the subglacial lake. There is optimism that microbial life in the lake may be possible despite high pressure, constant cold, low nutrient input, potentially high oxygen concentration and an absence of sunlight. Jupiter 's moon Europa and Saturn 's moon Enceladus may also harbor lakes or oceans below a thick crust of ice. Any confirmation of life in Lake Vostok could strengthen

1071-558: A hard or soft counterpart, and the distinction is a prominent feature of the language, which is usually shown in writing not by a change of the consonant but rather by changing the following vowel. Another important aspect is the reduction of unstressed vowels . Stress , which is often unpredictable, is not normally indicated orthographically , though an optional acute accent may be used to mark stress – such as to distinguish between homographic words (e.g. замо́к [ zamók , 'lock'] and за́мок [ zámok , 'castle']), or to indicate

1190-484: A language that "belongs to the European cultural space". The financing of Russian-language content by the state will cease, which the concept says create a "unified information space". However, one inevitable consequence would be the closure of public media broadcasts in Russian on LTV and Latvian Radio, as well as the closure of LSM's Russian-language service. In Lithuania , Russian has no official or legal status, but

If we are wise, the Lake will be allowed to reveal its secrets in due course." Lukin claims that hot-water drilling is much more dangerous for the microbiotic fauna, as it would boil the living species, and disturb the entire structure of water layers of the lake. Additionally, hot-water drilling would have required more power than

2023-566: A subglacial lake in the Vostok region was first suggested by Russian geographer Andrey Kapitsa based on seismic soundings made during the Soviet Antarctic Expeditions in 1959 and 1964 to measure the thickness of the ice sheet. The continued research by Russian and British scientists led to the final confirmation of the existence of the lake in 1993 by J. P. Ridley using ERS-1 laser altimetry. The overlying ice provides

Consonants include a fricative /ɣ/ , a semivowel /w⁓u̯/ and /x⁓xv⁓xw/ , whereas the Standard and Northern dialects have the consonants /ɡ/ , /v/ , and final /l/ and /f/ , respectively. The morphology features a palatalized final /tʲ/ in 3rd person forms of verbs (this is unpalatalized in the Standard and Northern dialects). During the Proto-Slavic (Common Slavic) times all Slavs spoke one mutually intelligible language or group of dialects. There

3094-920: Is collected using ice penetrating radar systems which range from commercial (or bespoke) ground penetrating radar (GPR) systems to coherent, chirped airborne sounders to swath-imaging, multi-frequency, or polarimetric implementations of such systems. Additionally, stationary, phase-sensitive, and Frequency Modulated Continuous Wave (FMCW) radars have been used to observe snow, ice shelf melt rates, englacial hydrology, ice sheet structure, and vertical ice flow. Interferometric analysis of airborne systems have also been demonstrated to measure vertical ice flow. Additionally, radioglaciological instruments have been developed to operate on autonomous platforms, on in-situ probes, in low-cost deployments, using Software Defined Radios , and exploiting ambient radio signals for passive sounding. The most common scientific application for radioglaciological observations

3213-446: Is estimated to contribute to the high gas concentration. Besides dissolving in the water, oxygen and other gases are trapped in a type of structure called a clathrate . In clathrate structures, gases are enclosed in an icy cage and look like packed snow. These structures form at the high-pressure depths of Lake Vostok and would become unstable if brought to the surface. In April 2005, German, Russian, and Japanese researchers found that

3808-569: Is sometimes considered to have played a significant role in the formation of modern Russian. Also, Russian has notable lexical similarities with Bulgarian due to a common Church Slavonic influence on both languages, but because of later interaction in the 19th and 20th centuries, Bulgarian grammar differs markedly from Russian. Over the course of centuries, the vocabulary and literary style of Russian have also been influenced by Western and Central European languages such as Greek, Latin , Polish , Dutch , German, French, Italian, and English, and to

In 2005, Russian was the most widely taught foreign language in Mongolia, and was compulsory in Year 7 onward as a second foreign language in 2006. Around 1.5 million Israelis spoke Russian as of 2017. The Israeli press and websites regularly publish material in Russian and there are Russian newspapers, television stations, schools, and social media outlets based in

4046-403: Is suspected that these Antarctic subglacial lakes may be connected by a network of subglacial rivers. Centre for Polar Observation & Modelling glaciologists propose that many of the subglacial lakes of Antarctica are at least temporarily interconnected. Because of varying water pressure in individual lakes, large subsurface rivers may suddenly form and then force large amounts of water through

Drilling of the core was deliberately halted roughly 100 m (300 ft) above the suspected boundary between the ice sheet and the liquid waters of the lake. This was to prevent contamination of the lake with the 60-ton column of Freon and kerosene used to prevent the borehole from collapsing and freezing over. From this core, specifically from ice that

4284-582: Is the first report of a fish species possibly residing in Lake Vostok. The fish is known to produce antifreeze proteins. Microbiologist David Pearce of the University of Northumbria in Newcastle, UK, stated that the DNA could simply be contamination from the drilling process, and not representative of Lake Vostok itself. The old ice cores were drilled in the 1990s to look for evidence of past climates buried in

On 28 September 2023, Latvian deputies approved The National Security Concept, according to which from 1 January 2026, all content created by Latvian public media (including LSM ) should be only in Latvian or

8449-692: The generation of immigrants who started arriving in the early 1960s). Only about 25% of them are ethnic Russians, however. Before the dissolution of the Soviet Union , the overwhelming majority of Russophones in Brighton Beach, Brooklyn in New York City were Russian-speaking Jews. Afterward, the influx from the countries of the former Soviet Union changed the statistics somewhat, with ethnic Russians and Ukrainians immigrating along with some more Russian Jews and Central Asians. According to

8568-480: The government bureaucracy for the lack of a reliable tool of communication in administrative, legal, and judicial affairs became an obvious practical problem. The earliest attempts at standardizing Russian were made based on the so-called Moscow official or chancery language, during the 15th to 17th centuries. Since then, the trend of language policy in Russia has been standardization in both the restricted sense of reducing dialectical barriers between ethnic Russians, and

8687-523: The hole to be left to freeze, creating a plug of ice in the bottom of the hole. Drilling stopped on 5 February 2011 at a depth of 3,720 m (12,200 ft) so that the research team could make it off the ice before the beginning of the Antarctic winter season. The drilling team left by aircraft on 6 February 2011. By plan, the following summer, the team was to drill down again to take a sample of that ice and analyze it. The Russians resumed drilling into

8806-550: The ice cap formed. The lake water is estimated to have been sealed off under the thick ice sheet about 15 million years ago. Initially, it was thought that the same water had made up the lake since the time of its formation, giving a residence time in the order of one million years. Later research by Robin Bell and Michael Studinger from the Lamont–Doherty Earth Observatory of Columbia University suggested that

8925-492: The ice was pierced, water from the underlying lake gushed up the borehole , mixing it with the Freon and kerosene used to keep the borehole from freezing. A new borehole was drilled and an allegedly pristine water sample was obtained in January 2015. The Russian team plans to eventually lower a probe into the lake to collect water samples and sediments from the bottom. It is hypothesized that unusual forms of life could be found in

9044-561: The ice, and the morphology of the bed. In addition bed echoes, radar returns from englacial layers are used in studies of the radio stratigraphy of ice sheets including investigations of ice accumulation , flow, and fabric as well as absence or disturbances of that stratigraphy. Radioglaciology data has also been used extensively to study subglacial lakes and glacial hydrology including englacial water, firn aquifers, and their temporal evolution. Ice penetrating radar data has also been used to investigate

9163-563: The ice, rather than for life, so the drilling equipment was not sterilized . Also Sergey Bulat, a Lake Vostok expert at the Petersburg Nuclear Physics Institute in Gatchina, Russia, doubts that any of the cells or DNA fragments in the samples would belong to organisms that might actually exist in the lake. He says that it is very probable that the samples are heavily contaminated with tissue and microbes from

9282-462: The lab procedures were performed in parallel with ice samples from Lake Erie, and the two resulting data sets were completely different. The Lake Erie sample exhibited many signals of human habitation, while the Lake Vostok ice samples exhibited no signals of human habitation. The Lake Erie sample also had an almost completely different profile of bacterial and eukaryotic phyla. Russian and French scientists have been carrying out molecular DNA studies of

9401-526: The lake has tides . Depending on the position of the Sun and the Moon, the surface of the lake rises about 12 mm (0.47 in). The lake is under complete darkness, under 355 bar (5,150 psi) of pressure, and expected to be rich in oxygen, so there is speculation that any organisms inhabiting the lake could have evolved in a manner unique to this environment. There is a 1 microtesla magnetic anomaly on

9520-411: The lake ice was significantly associated (p<0.05) with higher concentrations of ions and amino acids. While their previous work indicated the presence of bacteria that inhabit fish intestines, no sequences from fish were found. However, in the 2020 study, they found an rRNA sequence that was >97% similar to that from a rock cod common along the coast of Antarctica ( Notothenia coriiceps ). This

9639-518: The lake in January 2012 and reached the upper surface of the water on 6 February 2012. The researchers allowed the rushing lake water to freeze within the bore hole and months later; they collected ice core samples of this newly formed ice and sent them to the Laboratory for Glaciology and Environmental Geophysics in Grenoble, France, for analysis. Scientists first reported evidence of microbes in

9758-435: The lake was published in the science journal Nature on 20 June 1996. It has been confirmed that the lake contains large amounts of liquid water under the more than 3-kilometer-thick (1.9 mi) ice cap. The lake has at least 22 cavities of liquid water , averaging 10 kilometers (6 mi) each. The station after which the lake is named commemorates the Vostok (Восток), the 900-ton sloop-of-war ship sailed by one of

9877-408: The lake's liquid layer, a fossil water reserve. Because Lake Vostok may contain an environment sealed off below the ice for millions of years, the conditions could resemble those of ice-covered oceans hypothesized to exist on Jupiter 's moon Europa , and Saturn 's moon Enceladus . Russian scientist Peter Kropotkin first proposed the idea of fresh water under Antarctic ice sheets at the end of

9996-541: The lake, arguing that on breakthrough, water will rush up the borehole, freeze, and seal the other fluids out. Some environmentalist groups remain unconvinced by these arguments. The Antarctic and Southern Ocean Coalition has argued that this manner of drilling is a profoundly misguided step which endangers Lake Vostok and other subglacial lakes in Antarctica (which some scientists are convinced are inter-linked with Lake Vostok). The coalition has asserted that "it would be far preferable to join with other countries to penetrate

10115-524: The northwestern Xinjiang Uyghur Autonomous Region . Russian was also the main foreign language taught in school in China between 1949 and 1964. In Kazakhstan , Russian is not a state language, but according to article 7 of the Constitution of Kazakhstan its usage enjoys equal status to that of the Kazakh language in state and local administration. The 2009 census reported that 10,309,500 people, or 84.8% of

10234-515: The other hand, before the war, almost a quarter of Ukrainians were in favour of granting Russian the status of the state language, while after the beginning of Russia's invasion the support for the idea dropped to just 7%. In peacetime, the idea of raising the status of Russian was traditionally supported by residents of the south and east . But even in these regions, only a third of the respondents were in favour, and after Russia's full-scale invasion , their number dropped by almost half. According to

10353-461: The other three languages in the East Slavic branch. In many places in eastern and southern Ukraine and throughout Belarus, these languages are spoken interchangeably, and in certain areas traditional bilingualism resulted in language mixtures such as Surzhyk in eastern Ukraine and Trasianka in Belarus. An East Slavic Old Novgorod dialect , although it vanished during the 15th or 16th century,

10472-420: The outside world. The contamination possibility has been refuted by Scott Rogers, because the control measures were rigorous, and the combinations of organisms found in each of the ice samples were consistent with organisms living in a cold lake and ice (including a sequence from an Antarctic rock cod), and were inconsistent with contamination introduced while sampling or from the lab procedures. Also, all of

10591-446: The parliament approved a bill to close up all Russian language schools and kindergartens by the school year. The transition to only Estonian language schools and kindergartens will start in the 2024-2025 school year. In Latvia , Russian is officially considered a foreign language. 55% of the population was fluent in Russian in 2006, and 26% used it as the main language with family, friends, or at work. On 18 February 2012, Latvia held

10710-453: The peasants' speech was never systematically studied, as it was generally regarded by philologists as simply a source of folklore and an object of curiosity. This was acknowledged by the noted Russian dialectologist Nikolai Karinsky , who toward the end of his life wrote: "Scholars of Russian dialects mostly studied phonetics and morphology. Some scholars and collectors compiled local dictionaries. We have almost no studies of lexical material or

10829-459: The population aged 15 and above, could read and write well in Russian, and understand the spoken language. In October 2023, Kazakhstan drafted a media law aimed at increasing the use of the Kazakh language over Russian, the law stipulates that the share of the state language on television and radio should increase from 50% to 70%, at a rate of 5% per year, starting in 2025. In Kyrgyzstan , Russian

10948-418: The population was fluent in Russian in 2006, and 67% used it as the main language with family, friends, or at work. According to the 2019 Belarusian census , out of 9,413,446 inhabitants of the country, 5,094,928 (54.1% of the total population) named Belarusian as their native language, with 61.2% of ethnic Belarusians and 54.5% of ethnic Poles declaring Belarusian as their native language. In everyday life in

11067-479: The pronunciation of ultra-short or reduced /ŭ/ , /ĭ/ . Because of many technical restrictions in computing and also because of the unavailability of Cyrillic keyboards abroad, Russian is often transliterated using the Latin alphabet. For example, мороз ('frost') is transliterated moroz , and мышь ('mouse'), mysh or myš' . Once commonly used by the majority of those living outside Russia, transliteration

11186-472: The proper pronunciation of uncommon words or names. Russian is an East Slavic language of the wider Indo-European family . It is a descendant of Old East Slavic , a language used in Kievan Rus' , which was a loose conglomerate of East Slavic tribes from the late 9th to the mid-13th centuries. From the point of view of spoken language , its closest relatives are Ukrainian , Belarusian , and Rusyn ,

11305-402: The prospect for the presence of life on icy moons. Researchers working at Vostok Station produced one of the world's longest ice cores in 1998. A joint Russian, French, and United States team drilled and analyzed the core, which is 3,623 m (11,886 ft) long. Ice samples from cores drilled close to the top of the lake have been assessed to be as old as 420,000 years. The assumption

11424-446: The recognition of the achievements of the Russian research of Antarctica by the international scientific community, and of the unique operations on opening the subglacial Lake Vostok performed by Russian scientists on February 5, 2012." In January 2015, the Russian press stated that Russian scientists have made a new "clean" borehole into Lake Vostok using a special 50-kilogram probe that collected about 1 liter of water not adulterated by

11543-504: The region of Vostok Station made during the Soviet Antarctic Expedition in 1959 and 1964 to measure the thickness of the ice sheet. Kapitsa was the first to suggest the existence of a subglacial lake in the region, and the subsequent research confirmed his hypothesis. When British scientists in Antarctica performed airborne ice-penetrating radar surveys in the early 1970s, they detected unusual radar readings at

11662-491: The respondents), while according to the 2002 census – 142.6 million people (99.2% of the respondents). In Ukraine , Russian is a significant minority language. According to estimates from Demoskop Weekly, in 2004 there were 14,400,000 native speakers of Russian in the country, and 29 million active speakers. 65% of the population was fluent in Russian in 2006, and 38% used it as the main language with family, friends, or at work. On 5 September 2017, Ukraine's Parliament passed

11781-789: The results allowed deduction of the metabolic pathways represented in the accretion ice and, by extension, in the lake. The team found 3,507 unique gene sequences, and approximately 94% of the sequences were from bacteria and 6% were from Eukarya . Taxonomic classifications (to genus and/or species) or identification were possible for 1,623 of the sequences. In general, the taxa were similar to organisms previously described from lakes, brackish water, marine environments, soil, glaciers, ice, lake sediments, deep-sea sediments, deep-sea thermal vents, animals and plants. Sequences from aerobic , anaerobic , psychrophilic , thermophilic , halophilic , alkaliphilic , acidophilic , desiccation-resistant, autotrophic , and heterotrophic organisms were present, including

11900-582: The same borehole, which has already been contaminated with kerosene. According to the head of Russian Antarctic Expeditions, Valery Lukin, new equipment was developed by researchers at the Petersburg Nuclear Physics Institute that would ensure the lake remains uncontaminated upon intrusion. Lukin has repeatedly reassured other signatory nations to the Antarctic Treaty System that the drilling will not affect

12019-409: The scientists have been able to identify 255 contaminant species, but also have found an unknown bacterium when they initially drilled down to the lake's surface in 2012, with no matches in any international databases, and they hope it may be a unique inhabitant of Lake Vostok. However, Vladimar Korolev, the laboratory head of the study at the same institution, said that the bacteria could in principle be

12138-571: The site which suggested the presence of a liquid freshwater lake below the ice. In 1991, Jeff Ridley, a remote sensing specialist with the Mullard Space Science Laboratory at University College London , directed the ERS-1 satellite to turn its high-frequency array toward the center of the Antarctic ice cap . The data from ERS-1 confirmed the findings from the 1973 British surveys, but these new data were not published in

12257-452: The solid ice. Africa separated from Antarctica around 160 million years ago, followed by the Indian subcontinent , in the early Cretaceous (about 125 million years ago). About 66 million years ago, Antarctica (then connected to Australia) still had a tropical to subtropical climate, complete with marsupial fauna and an extensive temperate rainforest . The Lake Vostok basin is

12376-466: The subglacial and conditions of ice sheets and glaciers, including hydrology, thermal state, accumulation, flow history, ice fabric, and bed geology. In planetary science, ice penetrating radar has also been used to explore the subsurface of the Polar Ice Caps on Mars and comets. Missions are planned to explore the icy moons of Jupiter. Radioglaciology uses nadir facing radars to probe

12495-483: The subsurface of glaciers , ice sheets , ice caps , and icy moons and to detect reflected and scattered energy from within and beneath the ice. This geometry tends to emphasize coherent and specular reflected energy resulting in distinct forms of the radar equation. Collected radar data typically undergoes signal processing ranging from stacking (or pre-summing) to migration to Synthetic Aperture Radar (SAR) focusing in 1, 2, or 3 dimensions. This data

12614-464: The subsurface of ice shelves including their grounding zones, melt rates, brine distribution, and basal channels. There are currently two ice-penetrating radars orbiting Mars : MARSIS and SHARAD . An ice penetrating radar was also part of the ROSETTA mission to comet 67P/Churyumov–Gerasimenko . Ice penetrating radars are also included in the payloads of two planned missions to

12733-679: The survey carried out by RATING in August 2023 in the territory controlled by Ukraine and among the refugees, almost 60% of the polled usually speak Ukrainian at home, about 30% – Ukrainian and Russian, only 9% – Russian. Since March 2022, the use of Russian in everyday life has been noticeably decreasing. For 82% of respondents, Ukrainian is their mother tongue, and for 16%, Russian is their mother tongue. IDPs and refugees living abroad are more likely to use both languages for communication or speak Russian. Nevertheless, more than 70% of IDPs and refugees consider Ukrainian to be their native language. In

12852-459: The syntax of Russian dialects." After 1917, Marxist linguists had no interest in the multiplicity of peasant dialects and regarded their language as a relic of the rapidly disappearing past that was not worthy of scholarly attention. Nakhimovsky quotes the Soviet academicians A.M Ivanov and L.P Yakubinsky, writing in 1930: The language of peasants has a motley diversity inherited from feudalism. On its way to becoming proletariat peasantry brings to

12971-786: The two. Others divide the language into three groupings, Northern , Central (or Middle), and Southern , with Moscow lying in the Central region. The Northern Russian dialects and those spoken along the Volga River typically pronounce unstressed /o/ clearly, a phenomenon called okanye ( оканье ). Besides the absence of vowel reduction, some dialects have high or diphthongal /e⁓i̯ɛ/ in place of Proto-Slavic  * ě and /o⁓u̯ɔ/ in stressed closed syllables (as in Ukrainian) instead of Standard Russian /e/ and /o/ , respectively. Another Northern dialectal morphological feature

13090-511: The use of the language has some presence in certain areas. A large part of the population, especially the older generations, can speak Russian as a foreign language. However, English has replaced Russian as lingua franca in Lithuania and around 80% of young people speak English as their first foreign language. In contrast to the other two Baltic states, Lithuania has a relatively small Russian-speaking minority (5.0% as of 2008). According to

13209-429: The water from Lake Vostok that was frozen in the borehole, by constructing numerous DNA libraries , which are collections of fragments of DNA that allow scientists to identify which species of bacteria they may belong to. Samples taken from the lake so far contain about one part of kerosene per 1000 of water, and they are contaminated with bacteria previously present in the drill bit and the kerosene drilling fluid. So far,

13328-514: The water of the lake is continually freezing and being carried away by the motion of the Antarctic ice sheet , while being replaced by water melting from other parts of the ice sheet in these high pressure conditions. This resulted in an estimate that the entire volume of the lake is replaced every 13,300 years – its effective mean residence time. The coldest naturally occurring temperature ever observed on Earth, −89  °C (−128  °F ),

13447-432: The water. The researchers then switched to a new thermal drill head with a "clean" silicone oil fluid to drill the rest of the way. Instead of drilling all the way into the water, they said they would stop just above it when a sensor on the thermal drill detected free water. At that point, the drill was to be stopped and extracted from the bore hole. Removal of the drill would lower the pressure beneath it, drawing water into

13566-697: The world's ninth-most spoken language by total number of speakers . Russian is one of two official languages aboard the International Space Station , one of the six official languages of the United Nations , as well as the fourth most widely used language on the Internet . Russian is written using the Russian alphabet of the Cyrillic script ; it distinguishes between consonant phonemes with palatal secondary articulation and those without—the so-called "soft" and "hard" sounds. Almost every consonant has

13685-471: Was delivered to Progress Station in December 2021 and will be transported to the Lake Vostok research station and installed over the next four years. The drilling project has been opposed by some environmental groups and scientists who have argued that hot-water drilling would have a more limited environmental impact . The main concern is that the lake could become contaminated with the antifreeze that

13804-405: Was first introduced in North America when Russian explorers voyaged into Alaska and claimed it for Russia during the 18th century. Although most Russian colonists left after the United States bought the land in 1867, a handful stayed and preserved the Russian language in this region to this day, although only a few elderly speakers of this unique dialect are left. In Nikolaevsk, Alaska , Russian

13923-421: Was fluent in Russian in 2006, and 19% used it as the main language with family, friends, or at work. According to the 2014 Moldovan census , Russians accounted for 4.1% of Moldova's population, 9.4% of the population declared Russian as their native language, and 14.5% said they usually spoke Russian. According to the 2010 census in Russia , Russian language skills were indicated by 138 million people (99.4% of

14042-419: Was recorded at Vostok Station on 21 July 1983. The average water temperature is calculated to be around −3 °C (27 °F); it remains liquid below the normal freezing point because of high pressure from the weight of the ice above it. Geothermal heat from the Earth's interior may warm the bottom of the lake, while the ice sheet itself insulates the lake from cold temperatures on the surface. Lake Vostok

14161-402: Was the sixth-most used language on the top 1,000 sites, behind English, Chinese, French, German, and Japanese. Despite leveling after 1900, especially in matters of vocabulary and phonetics, a number of dialects still exist in Russia. Some linguists divide the dialects of Russian into two primary regional groupings, "Northern" and "Southern", with Moscow lying on the zone of transition between
