There are 9 out of 10 people in the world that are diagnosed with cancer and don’t know that somewhere in the world there is a vaccine that could cure them? Cancer is one of the scariest diseases in the world. Every day there’re doctors and scientists who are trying to find a cure. Many researchers and doctors do different types of research through people’s DNA, but also medical history of the family. Lastly, there has been a lot of […]
The history of HeLa cells are that they were taken from an woman named Henrietta Lacks by Doctor Gey who took the samples from her cancer without consent from either her or her family. Gey was able to reproduce the cells in his lab where he was able to send them to other researchers across the world. Companies were able to take advantage of this and sells the cells to other labs making a lot of profit. The scientific impact […]

Get help with your assignmentHave you ever wondered what structures lied in the dermis layer, or what was responsible for the stimulus reaction behind your involuntary response? Inside this vascularized layer lies microscopic structures. These structures carry out specific functions inside your dermis. These functions could be sweating, secreting, or an involuntary stimulus-response. Among these structures are the arrector pilli muscles. These Little collections of smooth muscle cells bring your hair to attention and create dimples or if preferable “goosebumps.” For animals, this involuntary […]
The BRAIN initiative objective is to unlock the mystery of the brain. An aspect of cracking this mystery is to map out the intricate neuronal signaling pathways happening between neurotransmitter for various activities. Building onto pre-existing methods and technologies, creating a map of the human brain continued to expand. A technology built on to provide key insight into these major neural networks is the use of genetically encoded fluorescent sensors. The explosive movement towards advancing the knowledge of the brain […]
The brain is an amazing and complex organ. It consists of a network of nerve cells (or neurons) that produce thought, memory, action, and feeling. This complex system changes and develops from childhood into adulthood to late life. The changes and development occur to maintain optimal behavioral responses. The brain grows and develops faster than any other parts of the body during infancy and as a toddler. Growth of the brain depends on many things, such as proper nutrition, exposure […]
It is a well known fact that cigarettes can cause lung cancer. Even though this fact is well known, some people smoke daily for their whole lives, and never get the disease. Because of this, there was a search for an explanation. Three studies have found a marker in the same region of DNA that seems to increase the chance of lung cancer. Researchers have not decided whether that gene directly causes lung cancer, or if the gene makes it […]
The Dalai Lama and Dolly the lamb, what could these two possibly have in common? The Dalai Lama being the spiritual leader of Tibetan Buddhism and Dolly, a lamb. The answer is nothing except a confused middle schooler in science class. I first heard about Dolly the lamb and confused it with the Dalai Lama. I believed the Dalai Lama to be a person that was being cloned over and over to allow for the same spiritual leader into perpetuity. […]
Having an abnormal number of chromosomes is known as aneuploidy. Aneuploidy opens the window for many possible diseases, and among these are down syndrome, acute lymphocytic leukemia, and acute myeloid leukemia. Normally, baby fetuses have 46 chromosomes; 23 from the sperm cell and 23 from the ovum. However, if there is an abnormal number of chromosomes, there will be complications during the growth of the fetus. Aneuploidy diseases can be deadly but new developing technology would help prevent this and […]
Stem cells are undifferentiated cells of multicellular organisms. Specifically embryonic stem cell are pluripotent, meaning they can create several different types of cells. With this new knowledge, biomedical research has ascended to new levels. To get embryonic stem cells biologists first produce via vitro fertilization, which is where an egg and sperm are combined outside of the body, isolated at blastocyst stage, and are finally grown in culture. Embryonic stem cells are not regarded as native pluripotent stem cells, which […]
In life’s hierarchy, cells make up the lowest level of organization. Cells can perform activities required to sustain life. A cell’s ability to divide to form new cells is the basis for growth and repair in organisms. Cells also play a key role in the recycling of carbon, a chemical element essential to life, and also participate in cellular processes such as photosynthesis. With these points in mind, it should be noted that cells come in one of two forms: […]
Case Study: Are Viruses Living? Dear Students, You came to me asking a question that has puzzled mankind ever since we have discovered them. Are viruses alive? Are the chicken pox, flu, HIV, and H1N1 viruses living? They are among the smallest microbes, but they can make people fell ill. So are they living or not? In my opinion, viruses are not alive. All living things have the same basic characteristics. According to Document B, organisms maintain homeostasis. Also, living […]
Whilst prokaryotes do not have a structured nucleus and other composite cell organelles found in eukaryotic cells, prokaryotic beings allocate the some general features with eukaryotes with the knowledge of cell division is, For instance, they both reproduce DNA in a semi traditional manner, and the separation of the lately formed DNA molecules can transpire before cell division can take place through cytokinesis. Despite such relationships, the eukaryotes may enclose a diverse number of DNA molecules, specific to each species, […]
