The Reasons Public Bathroom Stalls Do Not Touch the Ground

2 Comments

The reason commercial and industrial buildings have bathroom stalls which do not reach the floor is multifaceted. The design of doors which do not touch the ground provides a myriad of benefits including being easier to clean for custodial staff (e.g. reaching all areas with mop and bucket or pressure washer etc.), providing emergency access for first responders (e.g. elderly person who is unfamiliar and becomes confused thus falling down, an unconscious person who has suffered a health issue, wanted person hiding from law enforcement etc.), acting as a deterrent for unintended uses (e.g. using illicit drugs, consuming alcohol underage, sexual intercourse etc.), providing better air circulation between stalls so that odors do not linger, and limiting the spread of bacteria which reside upon the floor. In addition to these main reasons, it is additionally more cost effective as less material is used and the same door size fits and can be used for virtually all establishments, it is easier to escape from if a lock jams occurs, and toilet paper can be shared between stalls

The Origin of the Use of Analgesia While Giving Birth

1 Comment

Analgesia was not an option while giving birth until the mid 19th century as pain was believed to be a crucial part of the birthing experience. In 1591, Euphemia Maclean, a woman from Edinburgh, Scotland requested analgesia during the birth of her twins and was burned at the stake for this request. Analgesia started with Queen Victoria who used chloroform for the birth of her 8th child Leopold. It was Victoria’s experience that she told to others which made the practice catch on so quickly as Victoria felt that analgesia was an amazing invention which helped her immensely. In the 1950’s, the no medication approach swung back into fashion with Dr. Grantly Dick-Read, the first modern physician to suggest against analgesia as he believed the pain of childbirth to be psychological

The Fashion Police of North Korea

Leave a comment

In North Korea, music that is not state approved is illegal, international telephone calls are illegal, smiling in public upon the anniversary of Kim Il Sung’s death is illegal, and perhaps most bizarre, leather coats are illegal, with this last law passed in December of 2021 to dissuade North Korean citizens from imitating Kim Jong Un who wore a black cow hide coat in public on numerous occasions. This style of black leather coat became massively popular after Kim wore it in news media coverage in 2019 and because of this, imitation coats have become more readily available in North Korea. Surprisingly, fashion police are employed by the North Korean state to patrol and search for anyone wearing this style of garment as well as to search and help take down companies found manufacturing the coat

The Reason the Chinese Government Censored Footage of Soccer Games During the 2022 Fédération Internationale de Football Association World Cup

Leave a comment

During the 2022 Fédération Internationale de Football Association World Cup in Qatar, the Chinese government intercepted and censored all footage displayed in China in a concerted effort to prohibit Chinese citizens from observing World Cup fans from around the world enjoying and celebrating the games without masks as the Chinese government does not want the Chinese public to believe that doing so is a potential possibility

The Etymology of “Tetris” and the Block Shapes Available to Players

1 Comment

The videogame Tetris was named as such due to its creator, Alexey Pajitnov, amalgamating the Ancient Greek prefix “tetra” which means “4”, a direct reference to the various block shapes of Tetris which always have 4 cubes, and the term “tennis” as this was Pajitnov’s favorite sport. The shapes are referred to as “tetrominoes” and consist of an S-shape, Z-shape, T-shape, L-shape, line-shape, 7-shape, and a square-shape

The Rationale Behind the Iconic Mask of Anonymous

1 Comment

In 2008, the Anonymous hacktivism group staged mass protests across multiple cities worldwide. Because participating members were in need of adopting a physical disguise as they would be shifting from the online world into the physical world, early members of Anonymous spent the proceeding 48 hours calling comic book retailers, costume retailers, toy retailers etc. looking for identical disguises which could be purchased en masse for a reasonable price point. As it turned out, each one of these retailers had overstock of Guy Fawkes masks, most of them sitting in external storage and heavily discounted as no one wanted them after the release of the V for Vendetta film released in 2006, a rare miscalculation by manufacturers and retailers. Strangely, the iconography of the Anonymous organization was birthed out of an accidental fluke of overstock

The Renewable Resource of Urine Powered Electronics

1 Comment

Urine is rich in minerals and it is believed that this resource will be able to be harnessed and extracted efficiently and cost effectively at some point in the future to produce electrical energy. At the Bristol Robotics Laboratory in the U.K., urine is being studied as a potential energy resource for residential use within the near future (e.g. used to charge a smartphone etc.). Charging a smartphone with urine requires battery like fuel cells with Professor Ioannis Leropoulos (pronounced “yan-iss lee-raw-po-lis”) having developed a system capable of meeting this requirement. The application itself is referred to as “microbial fuel cell” technology, a system which leverages live bacteria to generate electrical current. Urine contains carbon, phosphorus, potassium, sulphur, magnesium, and creatinine, all elements which microbes require to continue living and growing which is why this technology functions as it does. The microbial fuel cell’s central tube is porous ceramic, allowing urine to permeate the tube and microbes to colonize it. As the elements of urine are consumed, electrons generated by the microbes are picked up by the cells of opposing wire coils, creating a battery. Not just any microbe will suffice however, as specific microbes are required for this process to be effective. To source the correct microbes, scientists leverage a plethora of microbes available within the natural environment (e.g. lake, pond, river sediment etc.). Each fuel cell produces 1.5 volts of electrical current, and when linked together in series, output can be increased to a level which is useful for daily activities. The system is able to be scaled so that it can be built into future homes, allowing for individuals and families to recycle urine as a means of generating electrical energy. Leropoulos’ work has been funded by the Bill & Melinda Gates Foundation as well as by the European Commission among others and is close to becoming commercially available as of 2020. For this system to benefit users, separate urinals would be installed but with redirected plumbing to funnel urine away from becoming mixed with common sewage and into a collection container, providing an on demand resource which can be utilized when needed

The Discovery of Bacterium Causing Stomach Ulcers

Leave a comment

For decades the medical community believed gastric ulcers were directly related to stress with the only options for relief being antacids and surgery. In the early 1980’s, Australian physicians Barry Marshall and Robin Warren discovered through biopsies of gastric ulcers, that nearly all were overrun by helicobacter pylori bacteria. Helicobacter pylori only seems to infect humans, as studies performed upon pigs and rats were unsuccessful as these animals were unable to contract the bacterium. Marshall decided to infect himself and within 5 days of doing so, he started running to the bathroom each morning to throw up. Tests demonstrated that Marshall had gastritis, a precursor to an ulcer. Marshall took antibiotics and was cured, proving once and for all that ulcers are caused by bacteria not stress. In 2005, Marshall and Warren won the Nobel Prize in Medicine for their findings

The First U.S. Presidential Vaccine Mandate

Leave a comment

U.S. President George Washington issued the first presidential vaccine mandate, requiring all soldiers within the continental army to become vaccinated against smallpox on February 5, 1777. 90% of deaths during the American Revolution were due to disease, with smallpox being the most prevalent and difficult pathogen for the military to control. Immunization was viewed as an achievable solution to a virtually insurmountable problem as death from smallpox plunged from 30% to 2% after a becomming immunized. Vaccination, or “variolation” as it was referred to during the era, was achieved by taking a small piece of an active smallpox sore from an infected person, and then introducing it to the person being inoculated via inhalation or by scratching their arm and introducing the virus by touch. The mandate, although initially detested, became highly successful in its pursuit of lowering soldier mortality rate, with 40,000 soldiers vaccinated by the end of 1777

The Study of Bacteriophages in Antibiotic Research and Why They May be the Next Major Scientific Breakthrough

Leave a comment

Bacteriophages, which are viral infections that reproduce to target and kill bacteria, were studied in Eastern Europe during the 1950’s by countries which did not have access to western medicine, including antibiotics. In 1 milliliter of sea water, billions of phages are present, with countless different varieties. Phages have tendril like appendages which are used to probe and identify hosts, clinging onto them, then forcing its own deoxyribonucleic acid down into the bacterial host. When this genetic code is introduced, it destroys the bacteria as a direct result. This leads to a chain reaction as hundreds more are produced each time this instance occurs, copies which then fledge out and find hosts of their own, building populations exponentially and wiping out bacterial infections completely. Bacteriophages were found prior to chemical antibiotics but when Penicillin was discovered, because it is so easy to develop and administer, chemical antibiotics became the clear path of choice in medicine with scientists not realizing the severity of this error until decades later. Antibiotics are often broad spectrum which is another reason antibiotic research overshadowed bacteriophagic research as different phages affect different bacteria and are therefore not broad spectrum. Because phages are self-replicating like bacteria, they have the ability to completely annihilate all bacteria presented before them in the same way that bacteria have the ability to totally annihilate their own host as well. Because of this, bacterial infections can be knocked out with 100% efficacy in all cases, regardless of the severity of the the infection, provided the correct phage is alotted enough time to do so. This is a task antibiotics often struggle to achieve and even if achieved, cannot be guaranteed in perpetuity as reinfection or resistance can occur at any time
