As a child, I loved playing outside. I spent my entire summer days outside with my siblings. It didn’t matter if my skin got one or two shades darker, it only mattered that I was having fun. However, growing up, I distinctly remember avoiding going outside because I didn’t want to get sunburnt and I … Read more

In the video Tiny Motors Can Clean Pollution – Headline Science, it is discussed that scientists are currently developing new tiny, soft motors that are run on things such as light magnets and chemical solutions. These new motors are supposed to serve specific functions, like cleaning up pollution. One specific motor, created by a team … Read more

A chemical reactions occurs when two or more molecules in an original substance rearrange and form a new substance. Many chemical reactions are irreversible. Meaning, once the reaction has occurred and created something new, you can not turn it back into the original substance. Chemical reactions are composed by a chemical equation. It starts with … Read more

Neurons. The key component to how we think, feel, and act. If it weren’t for neurons, we would live a senseless and boring life. Luckily, we have no shortage of neurons in our world. With billions of people, and even more animals covering the earth, neurons are everywhere, allowing us to experience the world in … Read more

Introduction Nuclear pore complexes (NPC) completes the vital role of channelling molecules between the cytoplasm and nucleus. NPC are aqueous channels formed from a complex network of evolutionarily conserved proteins known as nucleporins. They are roughly cylindrical in shape (Diameter ~120nm, height ~70nm) and embedded into the double membrane known as the nuclear envelope. Typically, … Read more

Alzheimer’s disease has become a growing problem all across the globe. It is the leading cause of dementia; in 60-70% of dementia cases, the patient has Alzheimer’s (Rich Roll Podcast). It is estimated that by the year 250, 135 ½ million people will have Alzheimer’s disease (Rich Roll). With so many people being affected across … Read more

Epilepsy is a neurological disease that affects 1.2% of the United States population. For treatment, there were two primary options before responsive brain stimulations. A patient could either receive medication or undergo surgery to remove the origin site of their seizures, or their seizure focus. However, a problem arose after drug-resistant patients had seizures starting … Read more

In the Chapter 3 reading, I found cell metabolism fascinating because I never understood the concept of metabolism; all I knew was that mine is not the same as it used to be when I was in high school. Metabolism is a series of chemical processes in our cells, which allow humans to do a … Read more

Microbial infections are considered as the major causes of morbidity and mortality. However, among the causative microbes, bacterial infection is the most prevalent one. Although various antibiotics discovered time to time rescued mankind from different dreadful diseases, the extensive and uncontrolled use of broad-spectrum antibiotics resulted in the development of antibiotic resistance in microbes. Thus, … Read more

Therapeutic antibodies are mostly manufactured in mammalian host cell lines including Chinese hamster ovary (CHO) cells, PER.C6 human cells and NS0 murine myeloma cells. The expression system of choice is usually determined by its ability to deliver high productivity with acceptable product qualities. Murine NS0 cells are non-immunoglobulin secreting myeloma cells that require the presence … Read more

Abstract In this lab experiment the overall purpose was to prove that energy exists in one way or another, and does not simply disappear. Thus proving the conservation of mechanical energy. Through a test gravitational potential energy using a cart, pulley, and mass hanger we determined the change in energy / change in distance was … Read more

Tubulin are the proteins specific to eukaryotic cells, however, prokaryotes—bacteria—also have a protein named FtsZ, which is homologous to tubulin. FtsZ protein are crucial for bacterial cell division process as they help bacteria to segregate daughter cells by forming a Z-ring at the center of dividing cell which after cell division, results into a septum … Read more

The prefrontal cortex (PFC) is the cerebral cortex covering the frontal lobe, crucial for executive functions and widely believed to be responsible for personality and other cognitive behaviour, including impulsivity and caution (Deyoung, Hirsh, Shane, Papademetris, Rajeevan & Gray, 2010). As these functions allow us to respond and react appropriately in social situations, it is … Read more

The Drake Lab: A Brief Novella Background: Prostates cancer is the uncontrolled growth of the prostate, capable of eventually metastasizing, or spreading to areas outside the prostate. This cancer is responsible for the death of 30.6 out of 100,000 men in the European Union^1. A type of hormone, called androgen, is responsible for the growth … Read more

Amphibians lack the diversity and development of secondary lymphoid organs seen in other vertebrates, such as mammals. The presence of true amphibian lymph nodes is unclear, and no amphibians have been demonstrated to possess Peyer’s patches (PP) or an equivalent1. The amphibian spleen’s role in both differentiation and activation of T and B cells means … Read more
