The Earliest Discovered Sewing Tools for Surgery and Textiles

Leave a comment

The earliest discovered eyed needles designed for surgery are from 30,000 B.C. This specific artifact was discovered within a cave located in Aurignacia, France. Additionally, other ancient needles have been uncovered within the region of Altai Krai, Russia, specialist needles without an eye but with a split head designed to grip the thread. These tools which are crafted from bird bone by the Denisovans, date back to 40,000 B.C. – 30,000 B.C. Both discoveries indicate that early human beings had developed sophisticated tools and techniques for sewing, tools which could have been used for many tasks ranging from textile repairs to complex tasks like surgery

How the Rabies Virus Pathogen Infects and Propagates Within Mammalian Hosts

Leave a comment

The rabies virus causes hostility within its host because aggressive behavior (e.g. biting etc.) is crucial for the transmission of the pathogen due to the fact that the virus is primarily secreted within the saliva of its hosts, although it can be present within and therefore transmitted via other tissues as well (e.g. infected brain tissue coming into contact with the open wound of a host etc.). The rabies virus primarily affects the central nervous system of its host, involving both the brain and spinal cord, causing inflammation of the brain referred to as “encephalitis”, and triggering various other neurological symptoms which help aide propogation (e.g. aggression, confusion, hallucinations etc.). The rabies virus travels along nerves from the wound site of the infection to the brain, where it then replicates and causes inflammation. Once the rabies virus reaches the brain, it can spread rapidly throughout the body via the central nervous system, leading to severe neurological symptoms and death in 100% of cases if left untreated

The Origin of Valentine’s Day and Valentine’s Day Cards

Leave a comment

Although the exact origin of Valentine’s Day is unknown during the modern day, the Catholic Church recognizes 3 different individuals named “Valentine” or “Valentinus”, all of whom were martyred, however it is possible these individuals were the same person. The Ancient Roman priest Valentinus, who lived during the 3rd century A.D., was imprisoned, perhaps falsely, by Ancient Roman emperor Claudius II (Claudius Gothicus). Claudius II legally prohibited marriage for young men, as he believed unmarried men without families made better soldiers. Valentinus may have performed wedding ceremonies for these soldiers covertly, until caught and executed on February 14, 269 A.D.. During his detention, Valentinus fell in love with the prison keepers daughter, a woman possibly named “Julia”, allegedly curing her of blindness. Valentinus signed the final letter he wrote to this woman prior to execution “Your Valentine”. It should be noted, this origin point is not supported by strong historical and/or physical evidence and may have been propagandized by medieval writers to romanticize Valentinus as a Catholic saint

The Importance of Gastrointestinal Microbes for Weight Loss

1 Comment

There are 100,000,000,000,000 (100 trillion) microbes within the gastrointestinal system and scientists have learned that by transplanting microbes from one animal to another, weight gain and weight loss can be turned on and off at will. Scientists now understand that the greater diversity a person has in terms of the types of microbial life which live within their body, the less likely they are to gain weight or maintain a higher than ideal body weight, with the exact opposite effect occurring in those who have lower than average values in reference to the number of microbes living within the body. Diets rich in fiber are typically associated with higher values of microbes, so increasing fiber intake, can significantly reduce overall body weight and promote the existence and health of many different kinds of microbes. Increasing fiber content for only a few days, has a measurable and marked effect upon microbrial gastrointestinal health

The Generational Health Effects of Smoking During Pregnancy

Leave a comment

Smoking during pregnancy doubles the risk of Attention Deficit Hyperactivity Disorder in children. Exposure to cigarette smoke during pregnancy can persist transgenerationally, being passed from parent to child, and can result within a higher probability of Attention Deficit Hyperactivity Disorder in 2nd and 3rd generation offspring. Smoking was purported as a remedy for morning sickness during the 1930’s which could explain why Attention Deficit Hyperactivity Disorder has been identified more and more throughout the past few decades. It takes a person with Attention Deficit Hyperactivity Disorder 150 milliseconds longer than a person without, to react to stimuli, which is the equivalent difference between a succesful hit and a near miss of a ball with a baseball bat

Since the 2006 Israeli democratic election, Gaza, Israel has been controlled by Hamas, a militant Islamic group considered terrorists by Israel and allied western governments.

The Country Which Executes the Most Convicted Persons and the Method of Execution Used

1 Comment

It is believed that China executes thousands of convicted persons each year, more than all other countries combined, as claimed by Amnesty International, due to the true value being closely guarded by the Chinese government. Typically Chinese executions are carried out with a single bullet to the back of the head/neck but intravenous poisons have also been used in recent decades

The Country With the Most Vegetarians Per Capita and the First Notation of Vegetarianism Within Western Literature

1 Comment

The country with the most vegetarians per capita is India, with 39% of the country identifying as vegetarian and/or vegan, a value which equates to 276,000,000 (276 million) people. This is primarily due to the dominant religion within India which is Hinduism, a faith which 79.8% of the country subscribes to, and to a lesser extent, Sikhism, a faith which promotes vegetarianism and is subscribed to by 1.7% of the country. Mexico trails India for the second spot internationally with 19% of the country identifying as vegetarian and Brazil takes the third spot with 14% having adopted this diet. The first time vegetarianism is mentioned within recorded western history is by the Ancient Greek mathematician Pythagoras around 500 BC, however it is unclear if this is the first recorded text worldwide

The Mass Unidentified Aerial Phenomena Sighting in Nuremberg, Germany During the Renaissance

In 1561, a mass unidentified aerial phenomena sighting was documented above Nuremberg, Germany. Witnesses report observing a large black triangular object and spherical crafts falling from the sky, producing clouds of smoke. Hundreds of spheres, cylinders, and other various shaped crafts jostled erratically for 1 hour before departing. The event was described as a “battle”
