Science Breakthrough-- The discovery of the Immortal Jellyfish


Do all living things die? Do all living things age? This particular species of jellyfish, known as the Turritopsis Nutricula seemingly never dies! This jecclyfish can regenerate itself over and over again. The process used by the jellyfish to accomplish this feat is called transdifferentiation. Transdifferentiation is the ability of one cell to change into another type of cell; the Turritopis Nutricula can do this to its entire body. Salamanders use this ability on a smaller scale when they re-grow a lost tail. In simpler words, transdifferentiation in biology takes place when a non-stem cell transforms into a different type of cell, or when an already differentiated stem cell creates cells outside its already established differentiation path.Since the Jellyfish do not die, their numbers increase without a natural death holding it back. Once native the Carribean the Turritopsis Nutricula has now spread throughout oceans across the world and it might actually upset the natural balance. The Telegraph reported that Scientist have stumbled upon “The font of eternal youth”, Dr. Maria Miglietta from the Smithsonian Tropical Marine Institute chimed in the article saying, “We are looking at a worldwide silent invasion.” (Telegraph. Meanwhile, experts have already started to work the jellyfish, wondering if it could be the key to an anti-aging medicinal breakthrough. If the jellyfish’s reverse aging technique could somehow be implemented in humans there is no telling what could become medically feasible. Perhaps this jellyfish will put pharmaceutical companies out of business. Who Knows, Humans might be immortal one day :) and it certainly does go against the laws of science that states that all Living Things will die. :)

Term 3 Class Test+ Reflections


I have met my target:) This time my aim was a 37 and or above, and with a pinch of luck, I've got 37 again. There will be no more tests and the next challenge facing me would be the end of year exams. Some reflections to make for this test: I need to look deeper into data analysis in the science test this time. I lost most of my marks in the test at this section :( I have also started devising a plan for my exams, and to start revising on chemical equations and acids and alkali. My aim is to get into SMTP next year, so science is a fundamental aspect in the criteria. I love Science so I have confidence to do well. Hey! This however doesn't mean that my target has been met. This is a little ironic.. HoHo. It should be" This however doesn't mean that my AIM has been met." Everyone's aim is too score full marks, so is mine. Now, I understand that so much hard work must be put in. Marks and accomplishments don't appear out of nowhere, it takes effort and time. I only know that I worked hard and looking back now, it is really a time to behold!
