A Chemical That Works Against Life Antibiotics (sometimes called antibacterials) are a strong group of medicines that are used to treat infections caused by bacteria and certain parasites. The term antibiotics comes from the Greek terms “anti” (which means “against”) and “bios” (which means “life”) While our scientific knowledge of antibiotics has only recently been developed, the practical application of antibiotics has existed for centuries. Many ancient cultures, including the ancient…

biomedicine world are trying their hardest everyday to enhance their knowledge of stem cells, does not mean that stem cells are the easiest organisms to work with. For example, if a scientist takes cancerous stomach cells from your body and grow them in a petri dish and the scientist figures out how the cancer started does not mean doctors can automatically inject stem cells in the human body and wait for the stem cells to work. If the scientist or doctor takes stomach cells and get those…

There he felt his anxiety skyrocket. Overwhelmed by the campus atmosphere, the newly acquired freedom from life and the lack of safe places for privacy, he is prone to yet more panic attacks and anxiety crisis. "Freedom is anxiety 's petri dish. If routine blunts anxiety, freedom incubates it. [...] Freedom says, "You 're on your own. Deal with it."" (Pg. 87), and for a short month, he tried his best to. Daniel would go hide in the library of the campus reading authors that would pike…

Spatial variability in local plankton communities can have large effects on the composition and diversity of the secondary production with in an area. Therefore, it is important for scientists to study the factors that affect plankton community’s abundance, diversity and dominance. In this study multiple physical and biological factors were observed in order to examine how surface plankton communities varied with distance from shore in the nearshore environment of the Southern California Bight.…

Bacteria Basics The Cambridge Online Dictionary characterizes bacteria as “very small organisms that are found everywhere and are the cause of many diseases” (Cambridge University). Bacteria is all around no matter where someone were to go. Bacteria can be very dangerous. People are exposed to bacteria from the time they are born to the day they die. Much of society think of public restrooms as bacterial feeding grounds, but what about high schools? Do high schools have dangerous sorts of…

The True Pain Of Safety Over many continents and through many time periods animal testing has had a strong presence in science. Many places and companies today have discontinued the use of animals due to its, at times, extremely inhumane practice. Though without the use of animals, many important discoveries, procedures, and vaccines wouldn’t have been found. Animal testing, though some has been found to be cruel, is a helpful tool for future discoveries, and should be continued today…

Scientists first discovered stem cells in the early 1900s. During this discovery, the scientists discovered that some cells had the capability to turn into blood cells, a completely different type of cell. These specific types of cells were classified as stem cells. Stem cells are known as undifferentiated cells, which means they do not have a specific function yet. Stem cells, since undifferentiated, are capable of becoming a specific type of cell such as a blood cell or a muscle cell. Unlike…

light microscope as compatible mating type (Wicks BL et al, 1996; Halliday CL et al, 1999) or stereoscope Niko- SZ-PT (Ohkusu M et al, 2002). Slide Mating Methd (Fraser JA et al, 2003):- In this method a sterile glass slide is placed in a sterile petri-dish at an angle of 20o. Then molten V8 juice agar is overlaid to form a thin film on it. Five ml of liquid V8 medium is added to the bottom of plate. The test strain is resuspended in distilled water and 10µl is inoculated with pipette from the…

Walk of the Dead The soft thud of a bowstring and the splatter that followed broke the silence that morning. With a low whistle Bruce said “Another clean kill, Michael, how do you do it?” “Practice,” I replied while I walked over to retrieve my bolt “ and a little luck.” This is how my life has been for as long as I can remember. More zombies to kill, brothers to annoy me and people to save. I reached down to retrieve my bolt which was lying discarded on the floor. I looked at the hollow…

In most societies, people will tend to define “good” as whatever brings pleasure and happiness and “bad” as whatever is burdening or distressing. Therefore, we should seek out the good in life and avoid the bad. However, in cases of abortion where a potential life is considered “bad”, is it justified to remove it? After all, life is often viewed as the highest intrinsic good, and thus deliberately taking it away becomes a serious moral issue. Pro-life arguments, or arguments opposing abortion,…
