Dogs adept at detecting scents can be utilized to identify children with COVID-19, providing a more cost-effective and efficient screening method during pandemics. A group of international researchers found that medical alert dogs, trained to detect the presence of the virus, can accurately screen school-aged children. By sniffing the students’ ankles and feet, the dogs demonstrated over 95% accuracy in lab settings when differentiating between positive and negative COVID-19 samples. When deployed in schools, the dogs achieved an 83% accuracy rate in identifying COVID-19 positive children and a 90% accuracy rate for COVID-19 negative children.

Bruceploitation: The Search for Bruce Lee’s Successor
Following the untimely death of Bruce Lee in 1973, the film industries of Hong Kong, Taiwan, and South Korea embarked on a quest to find a suitable successor to capitalize on his immense legacy. This era, later coined as “Bruceploitation,” saw a slew of actors adopting screen names reminiscent of the martial arts legend, such as Bruce Li, Bruce Lai, and Brute Lee, among others.

The Bruceploitation subgenre eventually lost momentum with the rise of another Hong Kong martial artist, Jackie Chan, whose films like Snake in the Eagle’s Shadow and Drunken Master helped solidify his position as the new face of martial arts cinema. This shift marked the end of the search for a Bruce Lee replacement and the beginning of a new era in the world of martial arts films.
McDonald’s: A Pillar of the American Service Economy
The McDonald’s Corporation has emerged as a potent emblem of the American service economy, currently accounting for 90% of the nation’s new job opportunities. From its humble beginnings with around 1,000 restaurants in 1968, McDonald’s has expanded its global presence, boasting over 28,000 establishments and inaugurating nearly 2,000 new outlets annually. Astonishingly, it is estimated that 1 in 8 workers in the United States has been employed by McDonald’s at some point in their career.
A somewhat popular joke draws a comparison between the mandatory military service practiced in some countries, such as Israel, which often includes both men and women, and the ubiquity of food service employment in the United States. The jest implies that working in the food service industry, particularly at McDonald’s, is almost an American rite of passage.
Operation Border Stone: The Deceptive Cold War Ploy
Throughout the Cold War, specifically between 1948 and 1951, the Czechoslovak secret police implemented Operation Border Stone, a scheme designed to entrap individuals attempting to flee the communist regime. To achieve this, they constructed counterfeit border crossings near West Germany, tricking escapees into believing they had successfully reached the West. The police then conducted sham “welcome” interviews, further reinforcing the illusion, only to guide the unsuspecting refugees into the clutches of the actual authorities.
Youth-Targeted Frequencies: Deterrents and Concerns
Certain sound frequencies are exclusively audible to teenagers, and some retailers utilize devices that produce these specific sounds to deter them from loitering. Typically, humans possess a broader capacity to perceive various frequencies in their youth, which gradually diminishes as they age. These high-frequency sounds are often referred to as “mosquito tones” due to their similarity to the buzzing of mosquitoes. They can be effective at preventing loitering, but their use has raised concerns about potential negative effects on young people’s hearing and general well-being.
Exclusive Passports: The Fascinating World of the Sovereign Military Order of Malta
The Sovereign Military Order of Malta issues the world’s rarest passport, with only a few hundred people possessing one. As of February 2018, there were around 500 diplomatic passports in circulation. Eligibility for this passport is exclusive and limited.
However, the passport’s utility is restricted, as countries such as the United Kingdom, United States, and New Zealand do not accept it for travel. Furthermore, many other countries and territories enforce similar rules. Out of the 26 Schengen Area member countries, only 23 recognize the passport.
Established in 1113 and officially recognized by Pope Paschal, the Sovereign Military Order of Malta is among the oldest Christian institutions. The Order’s full title is “Sovereign Military Hospitaller Order of Saint John of Jerusalem, of Rhodes, and of Malta,” reflecting its historical development and various headquarters over the centuries. The Order comprises over 13,500 knights, dames, and chaplains, alongside 80,000 volunteers and 25,000 medical employees. Although it does not govern any territory, it maintains diplomatic relations with more than 100 states.
The Order primarily operates as a charitable organization, providing medical aid worldwide. Passports are issued for four-year terms, allowing holders to carry out diplomatic assignments. In addition to passports, the Order also produces its own postage stamps and currency. Despite its unique status, the Sovereign Military Order of Malta passport is far from being one of the world’s most powerful passports.
Class & Language: A 1950s British Paradox
In the 1950s, it was observed that the British middle class often employed intricate language in an effort to appear more sophisticated. In contrast, the genuine upper class favored the simpler vernacular of the working class, opting for terms like “scent” rather than “perfume.”
A 1940 study examining the linguistic disparities between the American upper and middle classes found similar results. For example, the American upper class preferred the term ‘curtains,’ while the middle class opted for ‘drapes’. Interestingly, the affluent class in the US used the word ‘toilet,’ while their less wealthy counterparts said ‘lavatory’—a reversal of the British pattern.
Friends: Salary Standoff & Lasting Legacy
In 2000, as the “Friends” cast insisted on a $1,050,000 per episode salary, Garth Ancier from NBC created promotional material teasing the end of the series with the tagline, “After seven years of laughter, join us for the Friends series finale this Thursday.” This tactic led the cast to compromise on their wages.
“Friends” became a cultural phenomenon during its 10-year run from 1994 to 2004. The show’s iconic catchphrases, like Joey’s “How you doin’?” and Janice’s “Oh. My. God,” became widely recognized. Furthermore, Jennifer Aniston’s hairstyle as Rachel Green, dubbed “The Rachel,” gained immense popularity in the 1990s. The Central Perk coffeehouse, a popular setting on the show, inspired real-life coffee shops around the world, demonstrating the lasting impact of this beloved sitcom.
Ant Pheromone Experiment: Life in the Ant Graveyard
Upon death, ants emit a specific chemical that signals their demise, prompting fellow ants to remove and dispose of the deceased. In an intriguing experiment, a scientist successfully synthesized this chemical and applied it to a living ant. Despite the ant’s persistent efforts to clean itself, resist being carried, or return to its duties, its comrades continually escorted it to the designated graveyard. This behavior demonstrates the power of chemical communication within ant colonies, which relies on a complex system of pheromones to regulate tasks, coordinate activities, and maintain colony organization.
Online Education Shift Neutralizes Appearance-based Bias in Grading
During the COVID-19 pandemic, the transition to online learning revealed an interesting change in academic performance. Research shows that attractive female students, who were previously found to receive higher grades, experienced a leveling of this advantage when classes moved to a virtual format.
This finding suggests that biases based on physical appearance may have played a role in grading before the pandemic. The online learning environment, which often involves less face-to-face interaction, may have reduced the impact of attractiveness on academic evaluations. This highlights the importance of addressing appearance-based biases in educational settings to ensure fair and equitable assessment for all students.
