Hereditary, Lifelong Blood Disorder
SWBAT create a scientific research paper discussing a disorder caused by a genetic mutation and explain the impact of environmental factors. In this lesson, I will reinforce our previous lesson on DNA extraction and mutations, and protein folding. I will also reinforce writing skills necessary for the development of a scientific research report. The ability to construct a well written research report is an important skill and asset that a student needs in their academic and professional careers. Not only…...

Integrated Brain-Body: Perfect Posture and Spatial Orientation.
When the brain and body are totally integrated, it is easy for a person to maintain spatial orientation, balance, sit or stand tall and erect, maintain evenness in the gait while walking or running, and be aware of and respond to surrounding situations. When the brain and body are not totally integrated, the way our brains process information is compromised, affecting mental and physical performance. This lack of integration is referred to as Functional Neurological Disorganization. It is a common…...

Fond Memories From My Childhood
My uncle used to say “Music has the ability to bring you back to a certain memory in your life—good or bad”. I can remember fond memories in my childhood -- only when I hear certain songs from the late 50-70’s era. The songs I listened to were on vinyl records played on my uncle’s record player or at local diners that had a jukebox. I can recall begging my uncle for a quarter so that I could play my…...

The Relationship Between Crispr-cas9 and Stem Cells
Have you ever wondered if it is possible to cure cancer, have genetically related babies from same-sex parents, completely eradicate mosquitoes, resurrect an extinct species, or even insert a GIF into bacteria and have the bacteria replicate the GIF? With technology becoming more advanced by the hour, increasing possibilities are arising. In 1993, certain segments of DNA were discovered, called CRISPR (Clusters of Regularly Interspaced Short Palindromic Repeats). Twelve years later, Cas9, an enzyme responsible for separating areas of DNA…...

Human Experimentation and Exploitation in the Tuskegee Syphilis Study
As discussed in The Immortal Life of Henrietta Lacks, oppressed groups of people have often been the subjects of cruel experimentation. Lacks herself distrusted doctors and scientists at Johns Hopkins, but this fear also stemmed from an inability to fully understand the methods used by her doctors. Her doctors used cancer treatment methods which are now considered inhumane and brutal, and instead of curing her cancer, the methods spread her cancer throughout her abdomen, ultimately torturing her until her death.…...

The Impact of Invasive Species in an Ecosystem
There are many things that impact the environment and the ecosystems within them. Some of the impacts are beneficial, while others tear the ecosystem apart such as climate change, overpopulation and invasive species. While some of these events are natural many of these events are caused by the human population. In chapter five of Environmental Geology: Science, Land and Earth Systems by William A. Marsh and John Garcia Jr. there is a section that talks about ecosystem patterns and disturbances.…...

Preventing Crown-of-Thorns Starfish Spread
The Issues of Invasive Species: Crown-of-Thorns Starfish The basic definition of an invasive breed is when one species native to a different habitat is transported into a foreign ecosystem. Without any natural predators, it completely messes up the food chain for the native genus. Some of the ways an invasive species takes over its host habitat is that it has no natural predator, reproduces quickly, and outcompetes the native species in getting food. In other word, foreign inhabitants can potentially…...

The Evolution and Domination of Humans and the Management of Invasive Species
Modern man has built an empire. As a species, humans have made it to every continent, every ocean, and even space. The species did not begin this way; in fact, all modern humans can be traced to Homo erectus, a species that originated in Africa roughly 1.7 million years ago (Ayala 1995). Slowly making their way out of Africa, H. erectus introduced themselves to new environments, where they dominated the native species. 1.3 million years after migrating out of the…...

How Humans Responded to the Original Theory of Natural Selection
On February 12, 1809, Charles Robert Darwin was born, but his theory of evolution by natural selection wasn’t born until 1859 when he published The Origin of Species (Desmond). Darwin built and refined his theory throughout 1837-39 while exploring the world on the HMS Beagle. The HMS Beagle was the ship that Darwin voyaged the globe in order to complete his research which led to his publication of The Origin of Species. Not long after publication, there was some debate…...

The neuron is the basic building block of our nervous system. The neuron is made up of several parts, the cell body, the dendrites, the axon, and the terminal branches of the axon. The dendrites receive the message from other cells and passes it through the cell body. The message is passed through the axon and to the terminal branches. (Myers 2016). The message passing through the axon is an electrical signal. Some of our axons are covered with a…...

Many neurodegenerative disorders exist today, and several of these diseases are fatal and untreatable. The pathological mechanism for many neurodegenerative diseases has not been discovered yet, however most of these diseases systematically infect certain cranial tissues. One such tissue is a semi-permeable membrane that surrounds the brain and spinal cord. This membrane is known as the blood brain barrier (BBB), and understanding the structure of this barrier is vital to treating diseases that involve it.
