Hey , you ! Yeah , you all in the ceremonial robes about to perform a sacrifice in the name of the Almighty Blob ! Stop it right now ! Also , you over there , build the blob survival shelter . You may also stop .
This has get out of control . I know you all readthat Reuters clause , the one that stated that the Paris Zoological Park had acquired a “ mysterious newfangled organism ” nickname the “ blob ” inreference to a revulsion movie . And I recognise you all began to panic as you learn that said blob “ has no mouth , no stomach , no center , yet it can detect food and digest it , ” “ has almost 720 sexes , can move without legs or annexe and bring around itself in two moment if cut in half , ” and ( in the words of Paris Museum of Natural History director Bruno David ) “ has no nous but is able to learn ( … ) and if you merge two blob , the one that has learned will transmit its noesis to the other . ”
“ We bed for sure it is not a flora but we do n’t really if it ’s an animal or a fungus , ” David told Reuters . “ It behaves very surprisingly for something that count like a mushroom ( … ) it has the behavior of an animal , it is able to learn . ”

It is only rude that society would split into two camps . One welcoming the blob as a sort of god , a New God if you will , almighty in its potent blob abilities — but possibly able to be swayed from absorbing humanity by worship . The rest period of you were similarly panicked , but adjudicate your best opportunity was in build an underground Blobocalypse Ark to survive its sovereignty of terror , or until it pops or something . That ’s just part of being human , and I get it .
But I regret to inform you that while the blob is indeed somewhat mystifying , it is not new . It is the lowly Physarum polycephalum , a sludge mold , a contingent that was only mentioned in small text in Reuters ’ photo legend ( and not in its tweet ) . As such , it poses no threat to us .

Physarum polycephalum is a member of the phylum Mycetozoa , which is a group of ameboid , airy spore - create protists . Protists are eucaryotic being that are not a works , animal , or fungus , but that does not think of there ’s all that much equivocalness as to what the blob really is . It ’s basically a monumental unmarried - celled being ( formed by the mergerof many smaller specimens ) with tons of nuclei , and it seem like branching wiener vomit . It can indeed move , but slowly enough that its progress can only beobserved over several days . It ’s not considered a fungus because it eats entire organisms instead of breaking down organic affair into chemicals , but those organisms are microbes like bacterium or fungal spore .
Sometimes the gook mold also be active to avoid visible radiation and into dampish areas , sensing its surroundings through tubesfilled with cytoplasm(the goo inside cells ) . The pretty cryptical part is its power to con certain things about its environment and solve complex problems despite miss a nervous system .
That include things like becoming habituated to unpleasant but non - harmful chemicalssitting in the way of its path to food;balancing its diet ; andsolving mazesandtraps . Scientists have analyze whether slime molds can be brace automatically to activate “ gates ” exchangeable to logic gates , making themuseful for computing . But their principal relevance to computing is their ability to work complex publication like theTraveling Salesman Problem , which could put up insights intohardware - based information processing .
Other research has found it canshare some of its acquired memorieswith other P. polycephalum that flux with it to develop bighearted . The precise mechanisms by which they do thisremain moderately indecipherable . However , some of the decisions it name , such as where to move and what to eat , appear to be made by commission , per the Guardian :
Every part rhythmically expands and contracts , promote around the fluid indoors . If one part of the Plasmodium vivax touches something attractive , like food , it pulse more chop-chop and widen . If another part meet something repulsive , like brightness , it pulse more easy and head-shrinker . By total up all of these effects , the plasmodium flows in the best possible direction without a single conscious persuasion .
More late evidence has suggested that habituation to electronegative input like the unpleasant chemicals or high salinity concentration may be a matter of a P. polycephalum just engage the chemical , thus rise used to it . This might also explain how a gook mold portion memory board : when it merges with another , the absorbed chemicals are apportion too . Other behaviors , like seemingly hump where it ’s been , may also be explained bythe track of slimeit leaves behind as a mark .
As for the title that it has hundreds of sexes , well , that ’s less exciting than you may think . The mold grows spore thathatch into amoebascontaining only some of its transmissible information , which then have tomerge with compatible onesinto zygote that then themselves blend with others to take shape the big , single - celled version . Also , goop mould are not new and have been around for anestimated billion years or so .
So , in other run-in , this so - call new “ blob ” is in reality a well - known organism that has been studied for decades and is just a cool , harmless summation to the Paris Zoo … No , await ! Do n’t give me to the blob . Nooooooo !
