The Fallacy of Moss Always Growing Upon the North Side of Trees

1 Comment

Moss does not only grow on the north side of trees, as it is commonly believed by many. Moss typically grows on the north side but this rule only applies in the northern hemisphere. In the southern hemisphere, moss mostly grows on the south side of trees. The reason for this inversion is that in the northern hemisphere, because of the tilt of the Earth on its axis, the sun almost always appears to be a little south of directly overhead. That’s why rooms with windows facing south are brighter than rooms with windows facing north. This is important for moss because the north sides of trees within the northern hemisphere are shadier and therefore wetter. The south sides of trees get more sunlight, so water evaporates faster there

The Reason it is Impossible to Store, Purchase, and/or Sell Live Tuna

1 Comment

It is virtually impossible to store, purchase, and/or sell tuna fish live as tuna die shortly after capture. This is due to the fact that tuna breathe using ram-gill ventilation, which means that they must constantly stay in motion to have water pass over their gills and feed their body with oxygen. Motion is required continuously, exerted during both hours spent awake and time spent asleep. As the tuna is in motion, water flows into its mouth and over its gills and gill filaments, diffusing oxygen into the tunas bloodstream while simultaneously releasing carbon dioxide. This function is performed equally well at both slow and high rates of speed as long as consistent motion is achieved

The Fallacy of Transgender Female Athletes Competing at the Same Biological Level as Cisgender Female Athletes

2 Comments

It is a common misconception that transgender athletes who transition from male to female have the same sexual dimorphisms and therefore the same athletic capabilities and baseline statistics as cisgendered women when competing within athletic competition. Cisgender males on average have 40% more upper body muscle/strength than cisgendered women and 30% more lower body muscle/strength than cisgendered women, although these are mere approximations which span the entire world population which is why this is not always the case. Female hormones can reduce these advantages by 5% – 10% within the human body of elite athletes, but it is at the current time, as of 2023, impossible to completely reverse the advantage of biological male puberty for transgender male to female athletes. Surprisingly, hormone therapy rapidly reduces hemoglobin levels to that of cisgender women however all other baseline statistics remain relatively the same post transition when using hormone replacement therapy. Even after 36 months of treatment, virtually all other baseline levels are higher than the average cisgender female. These discoveries suggest that physical strength may be preserved in transgender women during the first 3 years of hormone replacement therapy. It should be noted, if the athlete does not go through male puberty, these male hormone induced advantages do not apply. This is because these traits are largely associated with testosterone but not entirely

The Minimum Salary Within the U.S. National Basketball Association

1 Comment

As of 2023, the minimum salary of a U.S. National Basketball Association professional player is $953,000 per year, which equates to $220.00 – $330.00 per hour as players work 60 – 90 hour work weeks (e.g. basketball game of 2 – 3 hours, post game interview of 1 – 2 hours, training of 3 – 4 hours etc.)

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

Botulism Toxin (Botox) Disabling Portions of the Human Brain Related to Emotion

2 Comments

Because human beings interpret emotions by mirroring one another, botulism toxin, more commonly referred to by the brand name “Botox”, when injected into the forehead, alters brain activity connected with various emotional states. The temporary paralysis of facial muscles from the use of Botox disables a person’s ability to mirror the person(s) they are interacting with. It also hinders their ability to read and interpret the facial expressions of others. Surprisingly, this information is being leveraged within studies of depression and patients diagnosed with borderline personality disorder, as it is believed that temporary paralysis of the forehead may help aid those who are experiencing clinical depression and/or a borderline personality disorder

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 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 Rationale as to Why Scientific Fact is Often Referred to as “Scientific Theory”

Leave a comment

The term “theory” placed behind suffixes of large theories like gravity, evolution, and special relativity (e.g. the Theory of Gravity, the Theory of Evolution, the Theory of Special Relativity etc.), doesn’t mean “theory” in the traditional sense. During the 20th century, Sir Isaac Newton’s Laws of Motion began to break down within the theories own borderlines as physics progressed further and further to answer continually larger and more complex questions. As a direct result of this, a grander, more encapsulating law was required to explain certain phenomena (e.g. the reason the sun has a corona of light bend around it during a total solar eclipse) which is why Albert Einstein’s Theory of Relativity is so immensely important, as it explains such phenomena after which Newton’s laws begin to break down (e.g. Newton’s ability to predict planetary orbit but not explain why such a function occurs in nature etc.). Eventually the international scientific community unanimously agreed that laws should not be named as such because they may not remain laws in the long term, as there may be concepts outside of them which help explain both the supposed law itself as well broader phenomena outside of the suppositional law. The term “theory” was utilized to replace the term “law” because something scientific which can change over time, is not or was not truly a law to begin with. The term “theory” is used in the connotation of an idea which accurately describes a phenomena and empowers an observer to accurately predict what they have yet to observe. An idea isn’t genuinely a “theory” until it’s supported by empirical evidence, before which time it remains as a “hypothesis”
