The Code of Hammurabi is a well-preserved Babylonian code of law of ancient Mesopotamia, dated to about 1754 BC (Middle Chronology). It is one of the oldest deciphered writings of significant length in the world. The sixth Babylonian king, Hammurabi, enacted the code. A partial copy exists on a 2.25-metre-tall (7.5 ft) stone stele. It consists of 282 laws, with scaled punishments, adjusting "an eye for an eye, a tooth for a tooth" (lex talionis) as graded based on social stratification depending on social status and gender, of slave versus free, man versus woman.

Nearly half of the code deals with matters of contract, establishing the wages to be paid to an ox driver or a surgeon for example. Other provisions set the terms of a transaction, the liability of a builder for a house that collapses, or property that is damaged while left in the care of another. A third of the code addresses issues concerning household and family relationships such as inheritance, divorce, paternity, and reproductive behavior. Only one provision appears to impose obligations on a government official; this provision establishes that a judge who alters his decision after it is written down is to be fined and removed from the bench permanently. A few provisions address issues related to military service.

The code was discovered by modern archaeologists in 1901, and its editio princeps translation published in 1902 by Jean-Vincent Scheil. This nearly complete example of the code is carved into a diorite stele in the shape of a huge index finger, 2.25 m (7.4 ft) tall. The code is inscribed in the Akkadian language, using cuneiform script carved into the stele. The material was imported into Sumeria from Magan - today the area covered by the United Arab Emirates and Oman.

It is currently on display in the Louvre, with replicas in numerous institutions, including the Oriental Institute at the University of Chicago, the Northwestern Pritzker School of Law in Chicago, the Clendening History of Medicine Library & Museum at the University of Kansas Medical Center, the library of the Theological University of the Reformed Churches in the Netherlands, the Pergamon Museum of Berlin, the Arts Faculty of the University of Leuven in Belgium, the National Museum of Iran in Tehran, the Department of Anthropology, National Museum of Natural History, Smithsonian Institution, the University Museum at the University of Pennsylvania, the Pushkin State Museum of Fine Arts in Russia, the Prewitt-Allen Archaeological Museum at Corban University, Garrett-Evangelical Theological Seminary, and Museum of the Bible in Washington, DC.

Rongorongo (; Rapa Nui: [ˈɾoŋoˈɾoŋo]) is a system of glyphs discovered in the 19th century on Easter Island that appears to be writing or proto-writing. Numerous attempts at decipherment have been made, none successfully. Although some calendrical and what might prove to be genealogical information has been identified, none of these glyphs can actually be read. If rongorongo does prove to be writing and proves to be an independent invention, it would be one of very few independent inventions of writing in human history.

Two dozen wooden objects bearing rongorongo inscriptions, some heavily weathered, burned, or otherwise damaged, were collected in the late 19th century and are now scattered in museums and private collections. None remain on Easter Island. The objects are mostly tablets shaped from irregular pieces of wood, sometimes driftwood, but include a chieftain's staff, a bird-man statuette, and two reimiro ornaments. There are also a few petroglyphs which may include short rongorongo inscriptions. Oral history suggests that only a small elite was ever literate and that the tablets were sacred.

Authentic rongorongo texts are written in alternating directions, a system called reverse boustrophedon. In a third of the tablets, the lines of text are inscribed in shallow fluting carved into the wood. The glyphs themselves are outlines of human, animal, plant, artifact and geometric forms. Many of the human and animal figures, such as glyphs 200 and 280 , have characteristic protuberances on each side of the head, possibly representing eyes.

Individual texts are conventionally known by a single uppercase letter and a name, such as Tablet C, the Mamari Tablet. The somewhat variable names may be descriptive or indicate where the object is kept, as in the Oar, the Snuffbox, the Small Santiago Tablet, and the Santiago Staff.

🔗 Chemicals

Fluoroantimonic acid is a mixture of hydrogen fluoride and antimony pentafluoride, containing various cations and anions (the simplest being H
₂F⁺
and SbF⁻
₆). This substance is a superacid that can be excess of a quadrillion times stronger than 100% pure sulfuric acid, depending on proportion of its ingredients. It has been shown to protonate even hydrocarbons to afford pentacoordinate carbocations (carbonium ions). Extreme caution needs to be in place when handling fluoroantimonic acid. It is exceptionally corrosive, but can be stored in containers lined with PTFE (Teflon).

🔗 Internet

StretchText is a hypertext feature that has not gained mass adoption in systems like the World Wide Web, but gives more control to the reader in determining what level of detail to read at. Authors write content to several levels of detail in a work.

StretchText is similar to outlining, however instead of drilling down lists to greater detail, the current node is replaced with a newer node. This ‘stretching’ to increase the amount of writing, or contracting to decrease it gives the feature its name. This is analogous to zooming in to get more detail.

Ted Nelson coined the term c. 1967.

Conceptually, StretchText is similar to existing hypertexts system where a link provides a more descriptive or exhaustive explanation of something, but there is a key difference between a link and a piece of StretchText. A link completely replaces the current piece of hypertext with the destination, whereas StretchText expands or contracts the content in place. Thus, the existing hypertext serves as context.

Finnair Flight 915 (AY915) was a scheduled flight by Finnair from Tokyo, Japan, over the North Pole to Helsinki, Finland, on 23 December 1987. In 2014, Finnish media reported a claim by two of the flight’s pilots that the Soviet Union had fired a missile at the aircraft, which exploded less than 30 seconds before impact. The allegations came out only in September 2014, when Helsingin Sanomat, the leading Finnish daily newspaper, published an extensive article on the matter. The Finnish Broadcasting Corporation YLE reported on the article on the internet the same day.

When the matter came out, it caused outrage in Finland among those politicians and civil servants, to whom it should have been reported at the time, and it was widely publicised and commented upon in the Finnish media, amidst allegations of Finlandization.

The alleged incident has been compared to other similar incidents involving the Soviet Union, such as the Aero Kaleva in 1940, Aeroflot Flight 902 in 1962, Korean Air Lines Flight 902 in 1978, Korean Air Lines Flight 007 in 1983. Co-captain Kaukiainen said that the Finnair pilots decided to speak out on the matter after Malaysia Airlines Flight 17 had been shot down in Ukraine on 17 July 2014.

🔗 Microbiology

Archaeal Richmond Mine acidophilic nanoorganisms (ARMAN) were first discovered in an extremely acidic mine located in northern California (Richmond Mine at Iron Mountain) by Brett Baker in Jill Banfield's laboratory at the University of California Berkeley. These novel groups of archaea named ARMAN-1, ARMAN-2 (Candidatus Micrarchaeum acidiphilum ARMAN-2 ), and ARMAN-3 were missed by previous PCR-based surveys of the mine community because the ARMANs have several mismatches with commonly used PCR primers for 16S rRNA genes. Baker et al. detected them in a later study using shotgun sequencing of the community. The three groups were originally thought to represent three unique lineages deeply branched within the Euryarchaeota, a subgroup of the Archaea. However, this has been revised, based on more complete archaeal genomic tree, that they belong to a super phylum named DPANN. The ARMAN groups now comprise deeply divergent phyla named Micrarchaeota and Parvarchaeota. Their 16S rRNA genes differ by as much as 17% between the three groups. Prior to their discovery all of the Archaea shown to be associated with Iron Mountain belonged to the order Thermoplasmatales (e.g., Ferroplasma acidarmanus).

Anti-gay purges in the Chechen Republic, a part of the Russian Federation, have included forced disappearances — secret abductions, imprisonment, torture — and extrajudicial killing by authorities targeting persons based on their perceived sexual orientation. An unknown number of people, who authorities detained on suspicion of being gay or bisexual, have reportedly died after being held in what human rights groups and eyewitnesses have called concentration camps.

Allegations were initially reported on 1 April 2017 in Novaya Gazeta, a Russian-language opposition newspaper, which reported that since February 2017 over 100 men had allegedly been detained and tortured and at least three had died in an extrajudicial killing. The paper, citing its sources in the Chechen special services, called the wave of detentions a "prophylactic sweep". The journalist who first reported on the subject went into hiding. There have been calls for reprisals against journalists who report on the situation.

As news spread of Chechen authorities' actions, which have been described as part of a systematic anti-LGBT purge, Russian and international activists scrambled to evacuate survivors of the camps and other vulnerable Chechens but were met with difficulty obtaining visas to conduct them safely beyond Russia.

The reports of the persecution were met with a variety of reactions worldwide. The Head of the Chechen Republic Ramzan Kadyrov denied not only the occurrence of any persecution but also the existence of gay men in Chechnya, adding that such people would be killed by their own families. Officials in Moscow were skeptical, although in late May the Russian government reportedly agreed to send an investigative team to Chechnya. Numerous national leaders and other public figures in the West condemned Chechnya's actions, and protests were held in Russia and elsewhere. A report released in December 2018 by the Organization for Security and Cooperation in Europe (OSCE) confirmed claims that persecution of LGBT persons had taken place and was ignored by authorities.

On 11 January 2019, it was reported that another 'gay purge' had begun in the country in December 2018, with several gay men and women being detained. The Russian LGBT Network believes that around 40 persons were detained and two killed.
