How Are New Elements Are Named?

New elements are typically temporarily named in their Latin name, broken down by the single digits ("un" is one, "oct" is eight, etc.) After a proper permanent name has been decided, the name must be presented to the global science community and it must be accepted by an international group of scientists. If it isn't approved, the name must be revised to something more acceptable. In the past, elements have been named after famous scientists such as Ernest Rutherford (Rutherfordium) and Albert Einstein (Einsteinium). However, the rules have changed for naming. It used to be that the element could be named after anything or the name could have been randomly generated. Now, the name must end with "-ium".

Glow-in-the-Dark Millipedes (Motyxia)

http://www.sciencedaily.com/releases/2011/09/110926131805.htm

Five Things I Learned:


  1. There are 12,000 discovered species of millipedes, but 100,000 are thought to exist.
  2. Millipedes are vegetarians that feed on decaying plant matter.
  3. Motyxia are blind and glow in the dark due to living underground a majority of the time, yet still have the ability to sense nightfall.
  4. Motyxia use their glow as a warning beacon and release toxic cyanide when endangered.
  5. There are only 3 areas in the world that you can see motyxia, and all of them are in California. They are the Santa Monica Mountains, the Tehachapi Mountains, and the southern Sierra Nevada Mountains.


The evidence that they used scientific method is that they first made a hypothesis about why the centipedes glowed in the dark. After making a hypothesis, they conducted various experiments and studies, such as the study on how Motyxia would survive with and without their glow in the wild, or tracing the Motyxia genus back through the evolutionary tree. Finally, they made a conclusion based on the data they had compiled.
