  Deinococcus Radiodurans and its Guinness World Record I am pleased to present a few interesting facts about Deinococcus radiodurans ( D. radiodurans) . D. radiodurans were discovered in 1956 by Professor Arthut W. Anderson in Oregon Agricultural Experiment Station, Corvallis Oregon. While Arthur W. Anderson was sterilizing canned meat to omit its decomposition; the emergence of various reddish colonies made a presence. One may wonder how something like this could have happened? The explanation for such an event is that the meat cans were exposed to high doses of radiation; These high temperatures of radiation were supposed to be enough to eliminate all known forms of life. For this reason, this bacterium should be given the appropriate name that would honor its ability to survive in extreme conditions. These radiation-resistant organisms were granted with the name of Deinoccocus Radiodurans. D. radiodurans literally means the "strange battle that endures radiation."  D. rad...

  Introduction                On my first day at the lab, I met Jonathan and my team; we introduced ourselves to each other. Right away, we set ourselves to practice with micropipettes. We learned the Dos and Don'ts of micro pipetting. There were steps to follow among these procedures, such as not utilizing the pipette without a tip attached and not exceeding the volume limits. Also, we were not to jam the pipette into the tip, given that our mentors let us know that micropipettes are expensive equipment that we can easily damage if not treated with precaution.               After getting to know what micropipettes are and how to implement them in the scientific field, my team and I next goal was to make LB and TGY broth. Beyond a scientific definition, what I understood about broth is that it is used as a food for bacteria. In other words, it is a place where bacteria can ...
