The Hair Issue

Another entry in the series of Trump on the cover of science journals.

Now check inside – there’s a model that you can cut out and create your own personalised hairstyle for Mr. T! Then send it to the White House – who knows, maybe he’ll be inspired to change his hair… It worked for Abe Lincoln, right? Then if he’d only change his style of leadership…

Today’s updates in the Devil’s Dictionary

Dear friends, finally some updates in the Devil’s Dictionary… Today’s words include archaea, gold standard, planarium, and the null hypothesis! Enjoy…

archaea  a unicellular organism known as an extremophile, generally meaning that it thrives in places the rest of us would find uncomfortable, such as hot thermal vents on the ocean floor, where they are thought to have evolved about 3.5 billion years ago, or in the tanks of Jacuzzis in hotels, the cloud palaces of Venus, or the belly button of a man who refused, for reasons that are unclear, to take a shower or otherwise bathe for many years. It is also unclear how the Archaea got into the belly button, although 3.5 billion years is probably enough time to crawl there from the ocean floor if you have a clear destination in mind and don’t make a lot of pit stops along the way. Some scientists believe that archeae invaded primitive bacteria and established a symbiotic relationship, leading to the evolution of the modern eukaryotes, although it is hard to see what they got out of the deal, unless they regarded the bacteria as hotel resorts where they could get cheap Jacuzzis.

Regarding the belly button, I cite from the original article: “Of special note are three phylotypes of Archaea [we found in the belly button], a domain of life often found in extreme environments and not previously reported from human skin [1], [27], multiple phylotypes of which we isolated from two independent samples (see online Supporting Information S1). Two of these three phylotypes were from an individual who self-reported not having showered or bathed for several years.” Reference: Jiri Hulcr, Andrew M. Latimer, Jessica B. Henley, Nina R. Rountree, Noah Fierer, Andrea Lucky, Margaret D. Lowman, Robert R. Dunn. A Jungle in There: Bacteria in Belly Buttons are Highly Diverse, but Predictable. Plos One: Nov. 7, 2012.

gold standard  an amount of pure gold equivalent to the value of an impact point. In ancient times, alchemists were actually awarded gold for their achievements (i.e., the degree to which their strange experiments came close to making it). In modern times, the gold standard was replaced with paper currency (journal articles), and is basically worthless in objective terms.

planarium  a strange model organism that never dies, but simply shrivels up for a while when food is scarce and then fattens again, and sometimes reproduces, when food is plentiful, resembling the way humans attempt to control their phenotype through various diets. When you attack a planarium with a knife and cut it into up to 256 pieces, each subunit is capable of reproducing an entire organism. The 257th piece is used as food. It is unclear why this hasn’t left the Earth piled in heaps upon heaps of planaria. The best explanation is that there are lots of planaria shriveled up in various locations, waiting for their chance to puff up and achieve world domination.

null hypothesis  a theory claiming that everything is nothing, or nothing is anything, or that nothingness pervades the universe, or would do so if the universe existed, but according to the null hypothesis it doesn’t, so what would there be to be filled with an infinite amount of nothingness? And does a system containing only nothingness obey the Second Law of Thermodynamics? Can the same volume hold different degrees of nothingness, which differ only in the density of nothingness against a background of nothingness, and if so can the nothingness in a system increase over time, or decrease, depending on how you see these things, to the point that eventually all the nothingness will be gone, and there will be nothing left at all, not even any nothingness?
