The Danger of Air Pollution Gaining Access to the Brain

air-pollution

The reason pollution has a metallic taste and scent and that it burns the eyes when exposed to it is because the particles of air pollution are tiny enough that they can travel through nerve cells, and gain direct entry to the brain, where the olfactory bulbar meets the frontal cortex, as there is no blood-brain barrier at this point. The body protects itself through the blood-brain barrier, which means that particles within the bloodstream, cannot get directly into the brain. This system has a slight flaw however as the nose acts as a direct conduit for incredibly tiny particles to bypass this security mechanism

The Scientific Study of Consciousness After Decapitation In Rodents

Brainwave activity in laboratory rats has been measured after decapitation. Scientists have determined that the brain stays conscious for 4 seconds after decapitation. Laboratory rat brain cells could theoretically start working again if intervention is quick enough supplying the brain with adequate oxygen and glucose

The Effects of Hydrocephalus

hydrocephalus

Hydrocephalus affects over 500,000 children worldwide. Hydrocephalus can be caused by infection, genetic anomalies, or head injuries. The reason hydrocephalus causes the heads of infants to grow so incredibly large is because all babies are born with soft, mailable skulls which are capable of expanding over 3x its typical size within the first 12 – 18 months after birth. Hydrocephalus is caused because the valve located between the left and right brain hemispheres which drains cerebrospinal fluid down the spine and into the abdomen, becomes blocked. When medical examinations are available, hydrocephalus can be diagnosed in utero allowing for immediate intervention. When the severity of hydrocephalus is diagnosed via computed tomography scan, the brain does not show up, as the water present takes up so much volume that the cavity where the brain would normally be, shows up as black, as water obstructs the ability of the scanner to take a complete image. The most common intervention of hydrocephalus is the installation of a shunt, but shunts have an 80% failure rate causing future uncertainty for those who have experienced hydrocephalus. Uganda has an unusually high occurrence rate of hydrocephalus primarily due to high rates of infant infection and lack of medical facilities and care

The Sale of Meat In New York City, United States of America During the 19th Century

Butchers in the 19th century often turned rotting meat into sausage so that the meat it was made up of was unidentifiable and palatable. Butchers added the chemical compound Borax which is sodium borate to cover up the scent of the meat because the boracic acid would kill any bacteria present upon the meat. It was later discovered that Borax is ideal for keeping wounds clean, killing cockroaches, and cleaning floors, which provides a clear frame of reference in terms of its potential safety hazards when consumed. The meat would still smell and taste bad and would cause those who consumed it to become sick but despite this, butchers would add red clothing dye made from coal tar which sometimes had arsenic in it to freshen up the grey and brown color of the meat so that it was more visually presentable to consumers. Finally, stale bread or cookies were added to bind everything together before the meat was sold

Bacteria and the Human Body 

bacteria

The human body is an ecosystem and in it is 10,000,000,000,000 (10 trillion) cells and 100,000,000,000,000 (100 trillion) microbes. It’s a ratio of 10:1 meaning that human beings are 90% microbial and only 10% mammalian. There are approximately 7000 different species of microbe within the intestine, approximately 700 different species within the mouth, approximately 300 – 400 different species within the vagina, and approximately 700 different species within and found upon the skin. Bacteria perform a myriad of tasks which includes regulating metabolic rates and regulating the immune system, among other various tasks

The Reason Why Genetic Diseases Remain Undetected 

laboratory-genetic-code

Every human being carries 10 – 20 faulty mutated genes which if matched with another person who carries the same mutation can cause hereditary disease processes. The reason these genes stay dormant and continue to be passed along without any particular generation noticing is because they have not been synchronized with a copy of that same mutation due to two people coming together to procreate. When this does occur however, the chance of inheriting the disease jumps from 0% to 50% automatically. The human genome is akin to a book with 3,000,000,000 (3 billion) letters, therefore small changes on any level is an immensely complex process and can lead to drastic changes under the right conditions
