🔗 Spaceflight

Quindar tones, most often referred to as the "beeps" that were heard during the American Apollo space missions, were a means by which remote transmitters on Earth were turned on and off so that the capsule communicator (CapCom) could communicate with the crews of the spacecraft. It was a means of in-band signaling to simulate the action of the push-to-talk and release-to-listen (often referred to as PTT) button commonly found on two-way radio systems and walkie-talkies.

Dmitry Konstantinovich Belyayev (Russian: Дми́трий Константи́нович Беля́ев, 17 July 1917 – 14 November 1985) was a Russian geneticist and academician who served as director of the Institute of Cytology and Genetics (IC&G) of the USSR Academy of Sciences, Novosibirsk, from 1959 to 1985. His decades-long effort to breed domesticated foxes was described by The New York Times as “arguably the most extraordinary breeding experiment ever conducted.” A 2010 article in Scientific American stated that Belyayev “may be the man most responsible for our understanding of the process by which wolves were domesticated into our canine companions.”

Beginning in the 1950s, in order to uncover the genetic basis of the distinctive behavioral and physiological attributes of domesticated animals, Belyayev and his team spent decades breeding the wild silver fox (Vulpes vulpes) and selecting for reproduction only those individuals in each generation that showed the least fear of humans. After several generations of controlled breeding, a majority of the silver foxes no longer showed any fear of humans and often wagged their tails and licked their human caretakers to show affection. They also began to display spotted coats, floppy ears, curled tails, as well as other physical attributes often found in domesticated animals, thus confirming Belyayev’s hypothesis that both the behavioral and physical traits of domesticated animals could be traced to "a collection of genes that conferred a propensity to tameness—a genotype that the foxes perhaps shared with any species that could be domesticated".

Belyayev’s experiments were the result of a politically motivated demotion, in response to defying the now discredited non-Mendellian theories of Lysenkoism, which were politically accepted in the Soviet Union at the time. Belyayev has since been vindicated in recent years by major scientific journals, and by the Soviet establishment as a pioneering figure in modern genetics.

🔗 Zoo 🔗 Primates

Ken Allen (February 13, 1971 – December 1, 2000) was a Bornean orangutan at the San Diego Zoo. He became one of the most popular animals in the history of the zoo because of his many successful escapes from his enclosures. He was nicknamed "the hairy Houdini".

Ken Allen was born in captivity at the San Diego Zoo in 1971. During the 1980s, Ken Allen gained worldwide attention for a series of three escapes from his enclosure, which had been thought to be escape-proof. During some of his escapes, his female companions would join him. Ken Allen's ability to outwit his keepers, as well as his docile demeanor during his escapes, resulted in fame. He had his own fan club, and was the subject of T-shirts and bumper stickers (most reading "Free Ken Allen"). A song, The Ballad of Ken Allen, was written about him.

Ken Allen developed prostate cancer and was euthanized on December 1, 2000. He was 29 years old.

🔗 Companies

Geneva Freeport (French: Ports Francs et Entrepôts de Genève SA) is a warehouse complex in Geneva, Switzerland, for the storage of art and other valuables and collectibles. The free port has been described as the "premier place" to store valuable works of art, and users "come for the security and stay for the tax treatment."

It is the oldest and largest freeport facility, and the one with the most artworks, with an estimated art collection value of US$100 billion. According to Jean-René Saillard of the British Fine Art Fund, "It would be probably the best museum in the world if it was a museum."

🔗 Mammals

Musth or must (an Urdu word, from Persian, lit. drunk) is a periodic condition in bull (male) elephants characterized by highly aggressive behavior and accompanied by a large rise in reproductive hormones.

Testosterone levels in an elephant in musth can be on average 60 times greater than in the same elephant at other times (in specific individuals these testosterone levels can even reach as much as 140 times the normal). However, whether this hormonal surge is the sole cause of musth, or merely a contributing factor, is unknown.

Scientific investigation of musth is problematic because even the most placid elephants become highly violent toward humans and other elephants during musth.

🔗 Equine

The Society in Dedham for Apprehending Horse Thieves is the "oldest continually existing horse thief apprehending organization in the United States, and one of Dedham's most venerable social organizations." Since its founding there have been more than 10,000 members including heads of state, Supreme Court justices, governors, popes, professors, generals, and other notables.

At one time membership of the "ancient and well known society" was limited to "the pillars of society" and the "very flower and pick of the vigor, manhood and rising youth of the vicinity." It has also been said that "for sheer whimsy, the Society... is without peer." Today it is a tax exempt non-profit social organization that continues to meet "just in case."

🔗 Medicine 🔗 Maine

The Jumping Frenchmen of Maine were a group of 19th-century lumberjacks who exhibited a rare disorder of unknown origin. The syndrome entails an exaggerated startle reflex which may be described as an uncontrollable "jump"; individuals with this condition can exhibit sudden movements in all parts of the body. Jumping Frenchmen syndrome shares some symptoms with other startle disorders.

Individuals with this condition were first found in the Moosehead Lake region of Maine, and were first described by George Miller Beard in 1878.

🔗 Russia 🔗 Archaeology

Onfim (Old Novgorodian: онѳиме, Onfime; also, Anthemius of Novgorod) was a boy who lived in Novgorod in the 13th century. He left his notes and homework exercises scratched in soft birch bark (beresta) which was preserved in the clay soil of Novgorod. Onfim, who was six or seven at the time, wrote in Old Novgorodian; besides letters and syllables, he drew "battle scenes and drawings of himself and his teacher".

On 17 September 2024, communication pagers simultaneously exploded across Lebanon and Syria in an apparent coordinated attack. Many of the pagers were owned by members of the Hezbollah militant group. Eighteen people were confirmed killed: eleven in Lebanon (including a child and at least two Hezbollah members) and seven in Syria. Around 4,000 people were reportedly injured, including Hezbollah members and civilians.

The blasts affected several Hezbollah strongholds, including Beirut's Dahieh suburb, southern Lebanon, and in the Beqaa Valley. Over 500 of the group's militants lost their eyesight. They called the incident the organization's "biggest security breach yet" and accused Israel of responsibility.

A day after Hamas launched its October 7 attacks on Israel in 2023, the Iranian-backed organization Hezbollah joined the conflict in support of Hamas by firing on Israel. This led to a series of cross-border military exchanges between Hezbollah and Israel. In February 2024, the secretary-general of Hezbollah, Hassan Nasrallah, told the group's members to use pagers instead of cell phones, claiming that Israel had infiltrated their cell phone network. Hezbollah then bought a new brand of pagers that were recently imported to Lebanon.

Earlier on the day of the explosion, Israel's domestic security agency, the Shin Bet, announced it had thwarted a Hezbollah plot to assassinate a former senior defense official using an explosive device.

Around 150 hospitals across Lebanon received victims of the attack, which saw chaotic scenes.

Juan Pujol García (Spanish: [ˈxwan puˈʝol ɣaɾˈθi.a]; 14 February 1912 – 10 October 1988), also known as Joan Pujol i García (Catalan: [ʒuˈan puˈʒɔl i ɣəɾˈsi.ə]), was a Spanish spy who acted as a double agent loyal to Great Britain against Nazi Germany during World War II, when he relocated to Britain to carry out fictitious spying activities for the Germans. He was given the codename Garbo by the British; their German counterparts codenamed him Alaric and referred to his non-existent spy network as "Arabal".

After developing a loathing of political extremism of all sorts during the Spanish Civil War, Pujol decided to become a spy for Britain as a way to do something "for the good of humanity". Pujol and his wife contacted the British Embassy in Madrid, which rejected his offer.

Undeterred, he created a false identity as a fanatically pro-Nazi Spanish government official and successfully became a German agent. He was instructed to travel to Britain and recruit additional agents; instead he moved to Lisbon and created bogus reports about Britain from a variety of public sources, including a tourist guide to Britain, train timetables, cinema newsreels and magazine advertisements.

Although the information would not have withstood close examination, Pujol soon established himself as a trustworthy agent. He began inventing fictitious sub-agents who could be blamed for false information and mistakes. The Allies finally accepted Pujol when the Germans expended considerable resources attempting to hunt down a fictitious convoy. Following interviews by Desmond Bristow of Section V MI6 Iberian Section, Juan Pujol was taken on. The family were moved to Britain and Pujol was given the code name "Garbo". Pujol and his handler Tomás Harris spent the rest of the war expanding the fictitious network, communicating to the German handlers at first by letters and later by radio. Eventually the Germans were funding a network of 27 agents, all fictitious.

Pujol had a key role in the success of Operation Fortitude, the deception operation intended to mislead the Germans about the timing, location and scale of the invasion of Normandy in 1944. The false information Pujol supplied helped persuade the Germans that the main attack would be in the Pas de Calais, so that they kept large forces there before and even after the invasion. Pujol had the distinction of receiving military decorations from both sides of the war – being awarded the Iron Cross and becoming a Member of the Order of the British Empire.
