🔗 Fungi 🔗 Physiology

Radiotrophic fungi are fungi which appear to perform radiosynthesis, that is, to use the pigment melanin to convert gamma radiation into chemical energy for growth. This proposed mechanism may be similar to anabolic pathways for the synthesis of reduced organic carbon (e.g., carbohydrates) in phototrophic organisms, which convert photons from visible light with pigments such as chlorophyll whose energy is then used in photolysis of water to generate usable chemical energy (as ATP) in photophosphorylation or photosynthesis. However, whether melanin-containing fungi employ a similar multi-step pathway as photosynthesis, or some chemosynthesis pathways, is unknown.

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.

🔗 Psychology

Learned helplessness is behavior exhibited by a subject after enduring repeated aversive stimuli beyond their control. It was initially thought to be caused from the subject's acceptance of their powerlessness: discontinuing attempts to escape or avoid the aversive stimulus, even when such alternatives are unambiguously presented. Upon exhibiting such behavior, the subject was said to have acquired learned helplessness. Over the past few decades, neuroscience has provided insight into learned helplessness and shown that the original theory actually had it backwards: the brain's default state is to assume that control is not present, and the presence of "helpfulness" is what is actually learned.

In humans, learned helplessness is related to the concept of self-efficacy; the individual's belief in their innate ability to achieve goals. Learned helplessness theory is the view that clinical depression and related mental illnesses may result from such real or perceived absence of control over the outcome of a situation.

The Deseret alphabet ( (listen); Deseret: 𐐔𐐯𐑅𐐨𐑉𐐯𐐻 or 𐐔𐐯𐑆𐐲𐑉𐐯𐐻) is a phonemic English-language spelling reform developed between 1847 and 1854 by the board of regents of the University of Deseret under the leadership of Brigham Young, the second president of the Church of Jesus Christ of Latter-day Saints (LDS Church). George D. Watt is reported to have been the most actively involved in the development of the script,^: 159 as well as being its first serious user.^: 12

The Deseret alphabet was an outgrowth of the idealism and utopianism of Young and the early LDS Church. Young and the Mormon pioneers believed "all aspects of life" were in need of reform for the imminent millenniumand the Deseret alphabet was just one of many ways they sought to bring about a complete "transformation in society",^: 142 in anticipation of the Second Coming of Jesus. Young wrote of the reform that "it would represent every sound used in the construction of any known language; and, in fact, a step and partial return to a pure language which has been promised unto us in the latter days," the Adamic language spoken before the Tower of Babel.

In public statements, Young claimed the alphabet would replace the traditional Latin alphabet with an alternative, more phonetically accurate alphabet for the English language. This would offer immigrants an opportunity to learn to read and write English, he said, the orthography of which is often less phonetically consistent than those of many other languages.^: 65–66 Similar neographies have been attempted, the most well-known of which for English is the Shavian alphabet.

Young also prescribed the learning of Deseret to the school system, stating "It will be the means of introducing uniformity in our orthography, and the years that are now required to learn to read and spell can be devoted to other studies."

During the alphabet's heyday between 1854 and 1869, scriptural passages in newspapers, selected church records, a $5 gold coin, and occasional street signs and correspondence used the new letters. In 1868-9, after much difficulty creating suitable fonts, four books were printed: two school primers, the full Book of Mormon, and a portion of it titled the Book of Nephi.

Despite heavy and costly promotion by the early LDS Church, the alphabet never enjoyed prolonged widespread use and has been regarded by historians as a failure. However, in recent years, aided by digital typography, the Deseret Alphabet has been revived as a cultural heirloom.

Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications. Phil Zimmermann developed PGP in 1991.

PGP and similar software follow the OpenPGP, an open standard of PGP encryption software, standard (RFC 4880) for encrypting and decrypting data.

🔗 Palaeontology 🔗 Amphibians and Reptiles 🔗 Mammals

Dimetrodon ( (listen) or , meaning "two measures of teeth") is an extinct genus of non-mammalian synapsids that lived during the Cisuralian (Early Permian), around 295–272 million years ago (Ma). It is a member of the family Sphenacodontidae. The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in the southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first described in 1878.

Dimetrodon is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it became extinct some 40 million years before the first appearance of dinosaurs. Reptile-like in appearance and physiology, Dimetrodon is nevertheless more closely related to mammals than to modern reptiles, though it is not a direct ancestor of mammals. Dimetrodon is assigned to the "non-mammalian synapsids", a group traditionally called "mammal-like reptiles". This groups Dimetrodon together with mammals in a clade (evolutionary group) called Synapsida, while placing dinosaurs, reptiles and birds in a separate clade, Sauropsida. Single openings in the skull behind each eye, known as temporal fenestrae, and other skull features distinguish Dimetrodon and mammals from most of the earliest sauropsids.

Dimetrodon was probably one of the apex predators of the Cisuralian ecosystems, feeding on fish and tetrapods, including reptiles and amphibians. Smaller Dimetrodon species may have had different ecological roles. The sail of Dimetrodon may have been used to stabilize its spine or to heat and cool its body as a form of thermoregulation. Some recent studies argue that the sail would have been ineffective at removing heat from the body due to large species being discovered with small sails and small species being discovered with large sails, essentially ruling out heat regulation as its main purpose. The sail was most likely used in courtship display with methods such as threatening rivals or showing off to potential mates.

🔗 China 🔗 Economics

Tang ping (Chinese: 躺平; pinyin: tǎng píng; lit. 'lying flat') is a lifestyle choice and social protest movement in China by some young people who reject societal pressures on hard work or even overwork (such as the 996 working hour system, which is generally regarded as a rat race with ever diminishing returns), and instead choose to "lie down flat and get over the beatings" via a low-desire, more indifferent attitude towards life. Novelist Liao Zenghu described "lying flat" as a resistance movement, and The New York Times called it part of a nascent Chinese counterculture. It has also been compared to the Great Resignation that began in America (and the western world) around the same time.

Unlike the hikikomori in Japan (who are socially withdrawn), these young Chinese people who subscribe to "lying flat" are not socially isolated, but merely choose to lower their professional and economic ambitions and simplify their goals, still being fiscally productive for their own essential needs, and prioritize psychological health over economic materialism.

🔗 California 🔗 Plants

Hyperion is a coast redwood (Sequoia sempervirens) in California that is the world's tallest known living tree, measured at 116.07 metres (380.8 ft) tall in 2019.

Hyperion was discovered on August 25, 2006, by naturalists Chris Atkins and Michael Taylor. The tree height of 115.55 m (379.1 ft) was verified by Stephen Sillett in 2006 using both a laser range finder and a fiberglass tape to measure the tree from the base to the crown. The tree has grown since then to reach 116.07 metres (380.8 ft) recorded in 2019. Hyperion was found in a remote area of Redwood National Park, inside of the originally designated park boundaries of 1968. The park also houses the second-, fourth- and fifth-tallest known trees, coast redwoods named Helios, Icarus, and Daedalus, which respectively measured 377, 371 and 363 feet in 2022.

The tree was named after the titan Hyperion from Greek mythology.

Hyperion is estimated to be between 600 and 800 years old and contain 530 m³ (18,600 cu ft) of wood.

The exact location of Hyperion is nominally secret but is available via internet search. However, in July 2022, the Redwood Park superintendent closed the entire area around the tree, citing "devastation of the habitat surrounding Hyperion" caused by visitors. Its base was trampled by the overuse and as a result ferns no longer grow around the tree. Anyone who gets too close could face up to six months in jail and a $5,000 maximum fine.

🔗 Cryptography 🔗 Cryptography/Computer science 🔗 Virginia

The Beale ciphers (or Beale Papers) are a set of three ciphertexts, one of which allegedly states the location of a buried treasure of gold, silver and jewels estimated to be worth over US$43 million as of January 2018. Comprising three ciphertexts, the first (unsolved) text describes the location, the second (solved) ciphertext the content of the treasure, and the third (unsolved) lists the names of the treasure's owners and their next of kin.

The story of the three ciphertexts originates from an 1885 pamphlet detailing treasure being buried by a man named Thomas J. Beale in a secret location in Bedford County, Virginia, in the 1820s. Beale entrusted a box containing the encrypted messages to a local innkeeper named Robert Morriss and then disappeared, never to be seen again. According to the story, the innkeeper opened the box 23 years later, and then decades after that gave the three encrypted ciphertexts to a friend before he died. The friend then spent the next twenty years of his life trying to decode the messages, and was able to solve only one of them which gave details of the treasure buried and the general location of the treasure. The unnamed friend then published all three ciphertexts in a pamphlet which was advertised for sale in the 1880s.

Since the publication of the pamphlet, a number of attempts have been made to decode the two remaining ciphertexts and to locate the treasure, but all efforts have resulted in failure.

There are many arguments that the entire story is a hoax, including the 1980 article "A Dissenting Opinion" by cryptographer Jim Gillogly, and a 1982 scholarly analysis of the Beale Papers and their related story by Joe Nickell, using historical records that cast doubt on the existence of Thomas J. Beale. Nickell also presents linguistic evidence demonstrating that the documents could not have been written at the time alleged (words such as "stampeding", for instance, are of later vintage). His analysis of the writing style showed that Beale was almost certainly James B. Ward, whose 1885 pamphlet brought the Beale Papers to light. Nickell argues that the tale is thus a work of fiction; specifically, a "secret vault" allegory of the Freemasons; James B. Ward was a Mason himself.

🔗 Visual arts 🔗 Morocco

Zellige (Arabic: [zˈliʑ]; Arabic: الزليج‎; also zelige or zellij or zileej) is mosaic tilework made from individually chiseled geometric tiles set into a plaster base. This form of Islamic art is one of the main characteristics of Moroccan architecture. It consists of geometrically patterned mosaics, used to ornament walls, ceilings, fountains, floors, pools and tables. The Moroccan traditional patterns and styles are found inside famous buildings such as Al-Qarawiyyin Mosque in Fez, the Alhambra in Granada, Spain, the Great Mosque of Cordoba, the Ben Youssef Madrasa in Marrakech, and the Hassan II mosque in Casablanca, which adds a new color palette with traditional designs.
