Canine COVID Detectives: Efficient Screening with Scent-Trained Dogs

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.
