Bruno Pontecorvo (Italian: [ponteˈkɔrvo]; Russian: Бру́но Макси́мович Понтеко́рво, Bruno Maksimovich Pontecorvo; 22 August 1913 – 24 September 1993) was an Italian and Soviet nuclear physicist, an early assistant of Enrico Fermi and the author of numerous studies in high energy physics, especially on neutrinos. A convinced communist, he defected to the Soviet Union in 1950, where he continued his research on the decay of the muon and on neutrinos. The prestigious Pontecorvo Prize was instituted in his memory in 1995.

The fourth of eight children of a wealthy Jewish-Italian family, Pontecorvo studied physics at the University of Rome La Sapienza, under Fermi, becoming the youngest of his Via Panisperna boys. In 1934 he participated in Fermi's famous experiment showing the properties of slow neutrons that led the way to the discovery of nuclear fission. He moved to Paris in 1934, where he conducted research under Irène and Frédéric Joliot-Curie. Influenced by his cousin, Emilio Sereni, he joined the French Communist Party, as did his sisters Giuliana and Laura and brother Gillo. The Italian Fascist regime's 1938 racial laws against Jews caused his family members to leave Italy for Britain, France and the United States.

When the German Army closed in on Paris during the Second World War, Pontecorvo, his brother Gillo, cousin Emilio Sereni and Salvador Luria fled the city on bicycles. He eventually made his way to Tulsa, Oklahoma, where he applied his knowledge of nuclear physics to prospecting for oil and minerals. In 1943, he joined the British Tube Alloys team at the Montreal Laboratory in Canada. This became part of the Manhattan Project to develop the first atomic bombs. At Chalk River Laboratories, he worked on the design of the nuclear reactor ZEEP, the first reactor outside of the United States that went critical in 1945, followed by the NRX reactor in 1947. He also looked into cosmic rays, the decay of muons, and what would become his obsession, neutrinos. He moved to Britain in 1949, where he worked for the Atomic Energy Research Establishment at Harwell.

After his defection to the Soviet Union in 1950, he worked at the Joint Institute for Nuclear Research (JINR) in Dubna. He had proposed using chlorine to detect neutrinos. In a 1959 paper, he argued that the electron neutrino (
ν
_e) and the muon neutrino (
ν
_μ) were different particles. Solar neutrinos were detected by the Homestake Experiment, but only between one third and one half of the predicted number were found. In response to this solar neutrino problem, he proposed a phenomenon known as neutrino oscillation, whereby electron neutrinos became muon neutrinos. The existence of the oscillations was finally established by the Super-Kamiokande experiment in 1998. He also predicted in 1958 that supernovae would produce intense bursts of neutrinos, which was confirmed in 1987 when Supernova SN1987A was detected by neutrino detectors.

Audie Leon Murphy (20 June 1925 – 28 May 1971) was an American soldier, actor, and songwriter. He was widely celebrated as the most decorated American combat soldier of World War II, and has been described as the most highly decorated soldier in U.S. history. He received every military combat award for valor available from the United States Army, as well as French and Belgian awards for heroism. Murphy received the Medal of Honor for valor that he demonstrated at the age of 19 for single-handedly holding off a company of German soldiers for an hour at the Colmar Pocket in France in January 1945, before leading a successful counterattack while wounded and out of ammunition.

Murphy was born into a large family of sharecroppers in Hunt County, Texas. After his father abandoned them, his mother died when he was a teenager. Murphy left school in fifth grade to pick cotton and find other work to help support his family; his skill with a hunting rifle helped feed his family.

After the attack on Pearl Harbor in 1941, Murphy's older sister helped him to falsify documentation about his birthdate in order to meet the minimum age requirement for enlisting in the military. Turned down initially for being underweight by the Army, Navy, and the Marine Corps, he eventually was able to enlist in the Army. He first saw action in the 1943 Allied invasion of Sicily; then in 1944 he participated in the Battle of Anzio, the liberation of Rome, and the invasion of southern France. Murphy fought at Montélimar and led his men on a successful assault at L'Omet quarry near Cleurie in northeastern France in October. Despite suffering from multiple illnesses and wounds throughout his service, Murphy became one of the most praised and decorated soldiers of World War II. He is credited with killing 241 enemy soldiers.

After the war, Murphy embarked on a 21-year acting career. He played himself in the 1955 autobiographical film To Hell and Back, based on his 1949 memoirs of the same name, but most of his roles were in Westerns. He made guest appearances on celebrity television shows and starred in the series Whispering Smith. Murphy was a fairly accomplished songwriter. He bred quarter horses in California and Arizona, and became a regular participant in horse racing.

Because Murphy had what would today be described as post-traumatic stress disorder (PTSD), then known as "battle fatigue", he slept with a loaded handgun under his pillow. He looked for solace in addictive sleeping pills. In his last few years, he was plagued by money problems but refused offers to appear in alcohol and cigarette commercials because he did not want to set a bad example. Murphy died in a plane crash in Virginia in 1971, shortly before his 46th birthday. He was interred with military honors at Arlington National Cemetery, where his grave is one of the most visited.

The Manned Orbiting Laboratory (MOL), originally referred to as the Manned Orbital Laboratory, was a never-flown part of the United States Air Force's human spaceflight program, a successor to the canceled Boeing X-20 Dyna-Soar military reconnaissance space plane project. The project was developed from several early Air Force and NASA concepts of crewed space stations to be used for reconnaissance purposes. MOL evolved into a single-use laboratory, with which crews would be launched on 40-day missions and return to Earth using a Gemini B spacecraft, derived from NASA's Project Gemini.

The MOL program was announced to the public on 10 December 1963 as an inhabited platform to prove the utility of putting people in space for military missions. Astronauts selected for the program were later told of the reconnaissance mission for the program. The contractor for the MOL was the Douglas Aircraft Company. The Gemini B was externally similar to NASA's Gemini spacecraft, although it underwent several modifications, including the addition of a circular hatch through the heat shield, which allowed passage between the spacecraft and the laboratory.

MOL was canceled in 1969, during the height of the Apollo program, when it was shown that uncrewed reconnaissance satellites could achieve the same objectives much more cost-effectively. U.S. space station development was instead pursued with the civilian NASA Skylab (Apollo Applications Program) which flew in the mid-1970s.

In the 1970s, the Soviet Union launched three Almaz military space stations, similar in intent to the MOL, but cancelled the program in 1977 for the same reasons.

There is a MOL space suit on display at the Oklahoma City Science Museum, presumably never used.

Speed tape is an aluminium pressure-sensitive tape used to perform minor repairs on aircraft and racing cars. It is used as a temporary repair material until a more permanent repair can be carried out. It has an appearance similar to duct tape, for which it is sometimes mistaken, but its adhesive is capable of sticking on an airplane fuselage or wing at high speeds, hence the name.

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.

The Welrod is a British bolt-action, magazine-fed pistol with an integrated silencer which was devised for covert operations during the Second World War by Major Hugh Reeves at the Inter-Services Research Bureau (later Station IX).

Station IX, being based in Welwyn, gave the Welrod its unusual name, being derived from "Wel" from "Welwyn" (a prefix used by covert equipment designed by Station IX) and "rod", gangland slang for gun, as a way to obscure its purpose.

Designed for use by irregular forces and resistance groups, the Welrod is an extremely quiet gun thanks to its integrated silencer. Approximately 2,800 were made in wartime and perhaps 14,000 in total when post-war examples are included.

The Dreyfus Affair (French: l'affaire Dreyfus, pronounced [lafɛːʁ dʁɛfys]) was a political scandal that divided the Third French Republic from 1894 until its resolution in 1906. "The Affair", as it is known in French, has come to symbolise modern injustice in the Francophone world, and it remains one of the most notable examples of a complex miscarriage of justice and antisemitism. The role played by the press and public opinion proved influential in the conflict.

The scandal began in December 1894 when Captain Alfred Dreyfus was convicted of treason. Dreyfus was a 35-year-old Alsatian French artillery officer of Jewish descent. He was sentenced to life imprisonment for allegedly communicating French military secrets to the German Embassy in Paris, and was imprisoned on Devil's Island in French Guiana, where he spent nearly five years.

In 1896, evidence came to light—primarily through an investigation instigated by Georges Picquart, head of counter-espionage—which identified the real culprit as a French Army major named Ferdinand Walsin Esterhazy. When high-ranking military officials suppressed the new evidence, a military court unanimously acquitted Esterhazy after a trial lasting only two days. The Army laid additional charges against Dreyfus, based on forged documents. Subsequently, Émile Zola's open letter J'Accuse…!, stoked a growing movement of support for Dreyfus, putting pressure on the government to reopen the case.

In 1899, Dreyfus was returned to France for another trial. The intense political and judicial scandal that ensued divided French society between those who supported Dreyfus (now called "Dreyfusards"), such as Sarah Bernhardt, Anatole France, Henri Poincaré and Georges Clemenceau, and those who condemned him (the anti-Dreyfusards), such as Édouard Drumont, the director and publisher of the antisemitic newspaper La Libre Parole. The new trial resulted in another conviction and a 10-year sentence, but Dreyfus was pardoned and released. In 1906, Dreyfus was exonerated and reinstated as a major in the French Army. He served during the whole of World War I, ending his service with the rank of lieutenant-colonel. He died in 1935.

The affair from 1894 to 1906 divided France into pro-republican, anticlerical, Dreyfusards and pro-Army, mostly Catholic "anti-Dreyfusards". It embittered French politics and encouraged radicalisation.
