Bonnie Bassler, a molecular biologist talks about her discoveries about the possibilities of communication between bacteria, and demonstrates the depths of bacterial quorum sensing, the method in which bacteria “talk” to each other. Bassler states “you think of yourselves as human beings, but I think of you as 99 percent bacterial” (Bassler, 2009). She then talks about how human bodies are made up of cells but in reality, the body is made up of fewer cells and mostly bacteria. Bassler thinks of humans at 90-99% bacteria for two reasons. First, humans have about 1 trillion human cells in them at all time, while at the same time we have 10 trillion bacterial cells in us as well, meaning we are 10 times more bacterial than human relative to the cells we exhibit. Secondly, humans have thirty thousand genes in their DNA, but there is hundred times more bacterial genes playing a role on humans’ lives as well. These two criteria allow Bassler to categorize humans as 90-99% bacteria, and 1-10% human. There are the three important functions of bacteria on humans that help keep up alive. Very importantly, they cover us in an invisible body armor …show more content…
However, when these bacteria are grouped together to have high cell density, the molecules they secrete amount to a certain number, and once that number is reached, the behavior of that bacteria is switched on and in this case, bioluminescence is created. Similarly, in my project, I am screening the anti bacterial activity using oils. Before I use the oil, I have to culture the bacteria overnight so that I could use them in the plates after 16-18 hours of incubation. Based on the talk, I believe that I have an idea on how bacteria grow. This Ted Talk has inspired me about science in numerous aspects. One way it inspires me about science is that is reveals an aspect to biology, which I was completely unaware
Bacteria are living things that have only one cell. Under a microscope, they look like balls, rods, or spirals. Many are helpful. Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt.
Margaret Sanger was born on September 14, 1879 in Corning, New York. Her name was Margaret Higgins. Sanger is the sixth of 11 surviving children born into a Roman Catholic Irish American family. During this time period, women were expected to have as many children as possible. Her parents, Michael and Anne Higgins, lived in poverty.
Bonnie and Clyde’s Mark on The 1930’s It was a time of little hope and poverty in the 1930’s when Bonnie Parker and Clyde Barrow first took their opinionated stand against the Federal Bureau of Investigation along with local police enforcement. During their four years of criminal activity, they scared many american citizens in the midwest and south. Their crimes left many crying due to their loved ones dying, registers were emptied, and officers lay dead on asphalt to meadow. In 1934, Police officers were enraged with the outlaws and found a way to force the killers to stop.
How would you feel if you took someone on a date and they left with someone else? In this short story, this is exactly what Sheila Mant does to the narrator in the story “The Bass, The River, and Sheila Mant” by W.D Wetherell. Based off indirect characterization and how Sheila doesn’t look at him when talking, and she compliments herself, she is not too nice of a person. Sheila is rude to the narrator, In the story “The Bass, The River, and Sheila Mant”, the narrator takes Sheila out on a date and she leaves him for someone else.
By understanding the connection between humans and the bacteria thanks to their knowledge of evolutionary history, they were able to replicate the effects of the disease in the bacteria. Research like this not only emphasizes the importance of evolutionary history, but it also has the potential to cure deadly diseases, like the one previously mentioned. Our biology class has studied cells as well, observing patterns through microscopes and identifying different parts of the cell, such as the nucleus and cell wall. Though we haven’t learned much about the mitochondria yet, the research discussed in this book has made me more curious about mitochondria and its role in the human
The narrator of the story “The Bass, the River, and Sheila Mant” is a young teenage boy, he has several conflicts that every teenager has to go through. Every decision came with a conflict or a question that he has to choose what is best for him. The boy that is tell this story has a internal and external conflict that he must figure out how to deal with. The internal conflict in this story is whether or not he should ask Sheila Mant out or not. The external conflict was whether or not he should rill in his line since he was trying to impress Sheila and she has already told him that he did not like fishing.
Christina Funk, junior, established a new organization that will benefit incoming freshman and returning students in their academics, student involvement, and social life. Funk’s organization, Students4Students was created in the beginning of August and has already over 50 official members in this organization. Students4Students consist of mentors known as Wolves and mentees known was Pups. Mentors must have attended University of West Georgia for a least a year and obtain a 2.7 GPA or higher. Most mentees are freshman who would like guidance during their first year of college.
Although microscopic single-celled organisms inhabited earth long before humans evolved from their primate ancestors, they continue to coexist and coevolve with humans today, flourishing as both harmless and deadly companions. Within her literary work Deadly Companions: How Microbes Shaped Our History, microbiologist Dorothy Crawford begins with a dramatic account of severe acute respiratory syndrome (SARS), the first pandemic of the twenty-first century. Crawford travels back in time four billion years ago to the origin of microbes, recounting the evolutionary history of microbes, showing how microbes spread and cause epidemics, and revealing how coevolution yields host resistance. Furthermore, Crawford explores the intertwining history of microbes and humans, with the purpose to reveal the link between the emergence of microbes and the cultural development of man.
"The transformational research by Drs. Doudna and Charpentier have uncovered molecular details of an amazing bacterial immunity mechanism. Their findings enable dramatic improvements in the speed, efficiency and flexibility of genome editing. " This quote explains why Jennifer Doudna and Emmanuelle Charpentier are such influential people. Their research is truly beneficial for humans for our future and species to keep living for years and decades and so forth.
The putrid smell of Escherichia coli is one that is immediately identifiable to the few lucky individuals who recognize its scent. It is also an aroma with which I became intimately sensitive to as I shuttled petri dishes of the bacterium in and out of an incubator. While my classmates shied away from the task of handling the pungent bacteria used in our recombinant DNA experiments, I took to the task eagerly, anything that would take me one step closer to my goal of researching. I had the opportunity to learn about lab techniques and cutting edge biology concepts the summer before my junior year, in an extracurricular biotechnology class at Northwestern University’s Center for Talent Development. The class, a three week crash course in the
Janet Smylie presents the current challenges facing indigenous Canadians in Westernised educational models. The author outlines the impact of colonisation on indigenous sociocultural belief systems highlighting this as a mitigating factor in the low levels of indigenous youth literacy. Smylie summarises the need to incorporate conceptualisation of Aboriginal culture, learning styles and perceptions when drafting framework for literacy outcomes. Additionally, the author highlights the need for self-determination by utilising the knowledge within communities to officially establish intrinsic connection between health and literacy outcomes in indigenous communities. In particular, embracing indigenous values such as metaphysical beliefs and traditional
, but have we ever thought what happens if the organism is sick? Naturally it recovers, but it also loses few of the diseased cells. These lost cells can be compared to humans, but not to these resourceful and ingenious, but rather to these abandoned and ditched by society. And honestly, they have really hard times, because modern society do not stop to help, and they are often unaided. Left just for themselves.
I am reading “The Bass, The River, and Sheila Mant” by W.D Wetherell, and I am on page 5. This short story is about a boy, the narrator, that has a crush on a girl, Sheila Mant. He learns little details about her as he observes and analysis her. As the summer goes on, he finally makes the decision to ask her out on a date, soon he would face a challenge that, at that time, must have been the hardest decision he’s ever had to make. Being compelled to choose between getting the girl, or catching a bass that would have been considered the biggest catch.
