Here are the Twitter #weirdscifacts for the past week!
431. May 18: Paris syndrome: some visitors to Paris experience hallucinations, feelings of persecution, etc. The city, which has such an influence on people’s imaginations around the world, apparently can overwhelm some of those who finally arrive.
432. May 19: William Perkin’s 1853 attempt to develop a malaria treatment instead led to first synthetic dye.
433. May 20: Saturn’s rings can sport waves!
434. May 21: The whip scorpion — no stinger or venom, but shoots acid from its rear!
435. May 22: The hexagon at Saturn’s North Pole, and its explanation! It is quite astonishing that very regular geometric figures can appear in a rather chaotic setting. (h/t my friend PD)
437. May 24: Nudibranchs: odd and beautiful “sea slugs”! There are plenty of unusual features of nudibranchs, but here I just marvel at their variety and unusual and beautiful appearance. An example is shown below, via Wikipedia. (inspiration via @DrBondar)
