🔗 Viruses 🔗 Statistics 🔗 Computational Biology

A super-spreader is an unusually contagious organism infected with a disease. In context of a human-borne illness, a super-spreader is an individual who is more likely to infect others, compared with a typical infected person. Such super-spreaders are of particular concern in epidemiology.

Some cases of super-spreading conform to the 80/20 rule, where approximately 20% of infected individuals are responsible for 80% of transmissions, although super-spreading can still be said to occur when super-spreaders account for a higher or lower percentage of transmissions. In epidemics with super-spreading, the majority of individuals infect relatively few secondary contacts.

Super-spreading events are shaped by multiple factors including a decline in herd immunity, nosocomial infections, virulence, viral load, misdiagnosis, airflow dynamics, immune suppression, and co-infection with another pathogen.

The Mosuo (Chinese: 摩梭; pinyin: Mósuō) are a small ethnic group living in Yunnan and Sichuan provinces in China, close to the border with Tibet. Dubbed the 'Kingdom of Women' by the Chinese, the Mosuo population of about 50,000 live near Lugu Lake in the Tibetan Himalayas 27°42′35.30″N 100°47′4.04″E.

Scholars use diverse terms and spellings to designate the Mosuo culture. Most prefer 'Mosuo' some spell it 'Moso', while a minority use neither term, but refer to them as the Na people.

The Mosuo people are known as the 'Kingdom of Women' because the Na are a matrilineal society: heterosexual activity occurs only by mutual consent and mostly through the custom of the secret nocturnal 'visit'; men and women are free to have multiple partners, and to initiate or break off relationships when they please.

🔗 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.

Project Babylon was a space gun project commissioned by then Iraqi president Saddam Hussein. It involved building a series of "superguns". The design was based on research from the 1960s Project HARP led by the Canadian artillery expert Gerald Bull. There were most likely four different devices in the program.

The project began in 1988; it was halted in 1990 after Bull was assassinated, and parts of the superguns were seized in transit around Europe. The components that remained in Iraq were destroyed by the United Nations after the 1991 Persian Gulf War.

🔗 Medicine 🔗 History of Science

Mummia, mumia, or originally mummy referred to several different preparations in the history of medicine, from "mineral pitch" to "powdered human mummies". It originated from Arabic mūmiyā "a type of resinous bitumen found in Western Asia and used curatively" in traditional Islamic medicine, which was translated as pissasphaltus (from "pitch" and "asphalt") in ancient Greek medicine. In medieval European medicine, mūmiyā "bitumen" was transliterated into Latin as mumia meaning both "a bituminous medicine from Persia" and "mummy". Merchants in apothecaries dispensed expensive mummia bitumen, which was thought to be an effective cure-all for many ailments. It was also used as an aphrodisiac. Beginning around the 12th century when supplies of imported natural bitumen ran short, mummia was misinterpreted as "mummy", and the word's meaning expanded to "a black resinous exudate scraped out from embalmed Egyptian mummies". This began a period of lucrative trade between Egypt and Europe, and suppliers substituted rare mummia exudate with entire mummies, either embalmed or desiccated. After Egypt banned the shipment of mummia in the 16th century, unscrupulous European apothecaries began to sell fraudulent mummia prepared by embalming and desiccating fresh corpses. During the Renaissance, scholars proved that translating bituminous mummia as mummy was a mistake, and physicians stopped prescribing the ineffective drug. Lastly, artists in the 17–19th centuries used ground up mummies to tint a popular oil-paint called mummy brown.

On 13 February 2017, the eldest son of Kim Jong-il and half-brother of Kim Jong-un, Kim Jong-nam, was attacked with the nerve agent VX at Kuala Lumpur International Airport in Malaysia. He had been exiled from North Korea in 2003 and had been living abroad.

Following his visit to the resort island Langkawi, Kim Jong-nam had arrived at terminal 2 sometime before 9:00 a.m. to take a 10:50 a.m. AirAsia flight to Macau. At approximately 9:00 a.m., two women attacked Kim Jong-nam with the VX nerve agent. He died about 15 to 20 minutes later.

The women were identified as Siti Aisyah, an Indonesian and Đoàn Thị Hương, a Vietnamese. Both were charged with the murder of Kim Jong-nam. The charges were dropped, although Hương pled guilty to "voluntarily causing hurt by dangerous weapons or means" and received a sentence of three years and four months. Four North Korean suspects left the airport shortly after the assassination and reached Pyongyang without being arrested. Other North Koreans were arrested but were released without charge.

It is widely believed that Kim Jong-nam was murdered on the orders of Kim Jong-un.

🔗 Video games

MIDI Maze is a networked first-person shooter for the Atari ST developed by Xanth Software F/X and released in 1987 by Hybrid Arts. The game takes place in a maze of untextured walls. The world animates smoothly as the player turns, much like the earlier Wayout, instead of only permitting 90 degree changes of direction. It has been suggested that MIDI Maze, using the built-in MIDI ports of the Atari ST for networking, introduced the concept of deathmatch combat. The game found a wider audience on the Game Boy as Faceball 2000.

The original MIDI Maze team consisted of James Yee as the business manager, Michael Park as the graphic and networking programmer, and George Miller writing the AI and drone logic.
