🔗 Psychology 🔗 Sexology and sexuality 🔗 Evolutionary biology

The sexy son hypothesis in evolutionary biology and sexual selection, proposed by Patrick J. Weatherhead and Raleigh J. Robertson of Queen's University in Kingston, Ontario in 1979, states that a female's ideal mate choice among potential mates is one whose genes will produce males with the best chance of reproductive success. This implies that other benefits the father can offer the mother or offspring are less relevant than they may appear, including his capacity as a parental caregiver, territory and any nuptial gifts. Fisher's principle means that the sex ratio (except in certain eusocial insects) is always near 1:1 between males and females, yet what matters most are her "sexy sons'" future breeding successes, more likely if they have a promiscuous father, in creating large numbers of offspring carrying copies of her genes. This sexual selection hypothesis has been researched in species such as the European pied flycatcher.

LK-99 is a proposed ambient pressure and room-temperature superconductor with a gray‒black appearance.^: 8 LK-99 has a hexagonal structure slightly modified from lead‒apatite and is claimed to function as a superconductor below 400 K (127 °C; 260 °F).^: 1 The material was investigated by a team of Sukbae Lee et al. from the Korea Institute of Science and Technology (KIST).^: 1 As of 26 July 2023 the discovery of LK-99 has not been peer reviewed or independently replicated.

The chemical composition of LK-99 is approximately Pb₉Cu(PO₄)₆O such that—compared to pure lead-apatite (Pb₁₀(PO₄)₆O)^: 5—approximately one quarter of Pb(2) ions are replaced by Cu(II) ions.^: 9 This partial replacement of Pb²⁺ ions (measuring 133 picometre) with Cu²⁺ ions (measuring 87 picometre) is said to cause a 0.48% reduction in volume, creating internal stress inside the material.^: 8

The internal stress is claimed to cause a heterojunction quantum well between the Pb(1) and oxygen within the phosphate ([PO₄]³⁻) generating a superconducting quantum well (SQW).^: 10 Lee et al claim to show LK-99 exhibits a response to a magnetic field (Meissner effect) when chemical vapor deposition is used to apply LK-99 to a non-magnetic copper sample.^: 4 Pure lead-apatite is an insulator, but Lee et al claim copper-doped lead-apatite forming LK-99 is a superconductor, or at higher temperatures, a metal.^: 5

The Satanic panic is a moral panic consisting of over 12,000 unsubstantiated cases of Satanic ritual abuse (SRA, sometimes known as ritual abuse, ritualistic abuse, organized abuse, or sadistic ritual abuse) starting in the United States in the 1980s, spreading throughout many parts of the world by the late 1990s, and persisting today. The panic originated in 1980 with the publication of Michelle Remembers, a book co-written by Canadian psychiatrist Lawrence Pazder and his patient (and future wife), Michelle Smith, which used the discredited practice of recovered-memory therapy to make sweeping lurid claims about satanic ritual abuse involving Smith. The allegations, which afterwards arose throughout much of the United States, involved reports of physical and sexual abuse of people in the context of occult or Satanic rituals. In its most extreme form, allegations involve a conspiracy of a global Satanic cult that includes the wealthy and elite in which children are abducted or bred for human sacrifices, pornography, and prostitution.

Nearly every aspect of the ritual abuse is controversial, including its definition, the source of the allegations and proof thereof, testimonies of alleged victims, and court cases involving the allegations and criminal investigations. The panic affected lawyers, therapists, and social workers who handled allegations of child sexual abuse. Allegations initially brought together widely dissimilar groups, including religious fundamentalists, police investigators, child advocates, therapists, and clients in psychotherapy. The term satanic abuse was more common early on; this later became satanic ritual abuse and further secularized into simply ritual abuse. Over time, the accusations became more closely associated with dissociative identity disorder (then called multiple personality disorder) and anti-government conspiracy theories.

Initial interest arose via the publicity campaign for Pazder's 1980 book Michelle Remembers, and it was sustained and popularized throughout the decade by coverage of the McMartin preschool trial. Testimonials, symptom lists, rumors, and techniques to investigate or uncover memories of SRA were disseminated through professional, popular, and religious conferences as well as through talk shows, sustaining and further spreading the moral panic throughout the United States and beyond. In some cases, allegations resulted in criminal trials with varying results; after seven years in court, the McMartin trial resulted in no convictions for any of the accused, while other cases resulted in lengthy sentences, some of which were later reversed. Scholarly interest in the topic slowly built, eventually resulting in the conclusion that the phenomenon was a moral panic, which, as one researcher put it in 2017, "involved hundreds of accusations that devil-worshipping paedophiles were operating America's white middle-class suburban daycare centers."

Of the more than 12,000 documented accusations nationwide, investigating police were not able to substantiate any allegations of organized cult abuse.

The Padmanabhaswamy temple treasure is a collection of valuable objects including gold thrones, crowns, coins, statues and ornaments, diamonds and other precious stones. It was discovered in some of the subterranean vaults of the Padmanabhaswamy Temple in Thiruvananthapuram, in the Indian state of Kerala, when five of its six (or possibly eight) vaults were opened on 27 June 2011. The vaults were opened on the orders of the Supreme Court of India, which was hearing a private petition seeking transparency in the running of the temple. The discovery of the treasure attracted widespread national and international media attention as it is considered to be the largest collection of items of gold and precious stones in the recorded history of the world. On the possibility of future appropriation of the wealth, for the need of a new management and proper inventorisation of the articles in the vaults, a public interest petition was registered with Supreme court of India. In 2020, the royal family won the rights to manage the temple, as well all its financial aspects. The Supreme Court of India overruled the Kerala High Court's legal jurisprudence based on regional facts and recognition of the nullified princely agreement based on "Ruler of Travancore."

For over two millennia, texts in Chinese herbology and traditional Chinese medicine have recorded medicinal plants that are also hallucinogens and psychedelics. Some are familiar psychoactive plants in Western herbal medicine (e.g., Chinese: 莨菪; pinyin: làngdàng, i.e. Hyoscyamus niger), but several Chinese plants have not been noted as hallucinogens in modern works (e.g.,Chinese: 雲實; pinyin: yúnshí; lit. 'cloud seed', i.e. Caesalpinia decapetala). Chinese herbals are an important resource for the history of botany, for instance, Zhang Hua's c. 290 Bowuzhi is the earliest record of the psilocybin mushroom xiàojùn 笑菌 (lit. "laughing mushroom", i.e. Gymnopilus junonius).

The Suwałki Gap, also known as the Suwałki corridor ([suˈvawkʲi] (listen)), is a sparsely populated area immediately southwest of the border between Lithuania and Poland, between Belarus and the Russian exclave of Kaliningrad Oblast. Named after the Polish town of Suwałki, this choke point has become of great strategic and military importance since Poland and the Baltic states joined the North Atlantic Treaty Organization (NATO).

The border between Poland and Lithuania was formed after the Suwałki Agreement of 1920; but it carried little importance in the interwar period as at the time, the Polish lands stretched farther northeast, while during the Cold War, Lithuania was part of the Soviet Union and communist Poland belonged to the Soviet-led Warsaw Pact alliance. The dissolution of the Soviet Union and the Warsaw Pact created borders that cut through the shortest land route between Kaliningrad (Russian territory isolated from the mainland) and Belarus (Russia's ally). As the Baltic states and Poland eventually joined NATO, this narrow border stretch between Poland and Lithuania became a vulnerability for the military bloc because, if a hypothetical military conflict were to erupt between Russia and Belarus on one side and NATO on the other, the capture of the 65 km (40 mi)-long strip of land between Russia's Kaliningrad Oblast and Belarus would likely jeopardise NATO's attempts to defend the Baltic states. NATO's fears about the Suwałki Gap intensified after 2014, when Russia annexed Crimea and launched the war in Donbas, and further increased after Russia invaded Ukraine in February 2022. These worries prompted the alliance to increase its military presence in the area, and an arms race was triggered by these events.

Both Russia and the European Union countries also saw great interest in civilian uses of the gap. In the 1990s and early 2000s, Russia attempted to negotiate an extraterritorial corridor to connect its exclave of Kaliningrad Oblast with Grodno in Belarus, but Poland, Lithuania and the EU did not consent. Movement of goods through the gap was disrupted in summer 2022, during the Russian invasion of Ukraine, as Lithuania and the European Union introduced transit restrictions on Russian vehicles as part of their sanctions. The Via Baltica road, a vital link connecting Finland and the Baltic states with the rest of the European Union, goes through the area and, as of November 2022, is under construction in Poland as expressway S61.

The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems.

X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interface – this is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces.

X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses.

🔗 Sanitation

A bidet shower—also known as a handheld bidet, commode shower, toilet shower, health faucet, bum shower, shatafa (from the Arabic: شَطَّافَة [ʃɑtˤˈtˤɑːfɑ], "rinser") or bum gun—is a hand-held triggered nozzle that is placed near the toilet and delivers a spray of water used for anal cleansing and cleaning of the genitals after using the toilet for defecation and urination, popularised by Arab nations where the bidet shower is a common bathroom accessory. The device is similar to that of a kitchen sink sprayer.

In predominantly Catholic countries, the Muslim world, in the Eastern Orthodox and Hindu cultures, and in some Protestant countries such as Finland, water is usually used for anal cleansing, using a jet (bidet shower, bidet) or vessel, and a person's hand (in some places only the left hand is used).
