Meitnerium is another highly radioactive element that has a half life in the seconds. It is named for Lise Meitner who was one of the discoverers of process to achieve nuclear fission. She did not receive the Nobel Prize for her work. Some attribute this to endemic sexism. Meitnerium has not had many chemical studies on it as it’s half life is to brief.
Chickens are domesticated bird, however their ability to survive now in general depends on humanity survival. It’s tied to Meitnerium as much like Lisa Meitner chickens do not get nearly the praise for the contribution to humanities continued survival that they should have.
Darmstadtium is element 110 (only 8 left) and again a highly radioactive with a short half life. It’s named after Darmstadt as it was originally discovered by a team of nuclear physics in the town.
Taenia Solium is better known as a tape worm. The human varieties of which have in general come from pork meat that has been poorly cured or cooked. I’m not making any purposeful reference to the town of Darmstadt by tying it to Darmstadtium! The creature is very like any heavy transactinide in it ability to only survive in specific environments and be somewhat deadly when not properly managed. Darmstadtium was the only element in the 110-118s left to fit it as a animal as element, when I was allocating the last few animals to elements.
