Today I Learned: 1) A ring species is a kind of species undergoing spatial speciation where the species varies considerably, but continuously, across its geographic range. Typically a ring species varies enough from one end to the other that members of the populations at opposite ends can't interbreed. It's called a "ring" species because in some cases, the geographic range bends back so that the populations at either end actually overlap, but are still distinct because they can't interbreed. 2) One of the common traits of developing market (i.e., third-world country) is high local currency volatility -- many developing markets have a large degree of political or financial uncertainty, which leads to rapid and frequent changes in the relative value of the nation's currency. 3) If you 3D print a part and it comes out warped, you can sometimes fix it by heating it with a blow dryer and twisting it back into shape.
