    Yeah, I guess there are two sides to the problem here. People that do fraught on a level that is hard to perceive and those that do fraught on a grandiose level. I agree with all of your comments, especially what you say about how the harder to perceive fraught is actually more damaging to science.

    But I guess the question initially posed why some people would do these high risk frauds. Why would someone say they’ve got a working room temp/low pressure supercomputer? Why would someone say they’re able to turn anything into gold? As you say, these are just some spectacular outliers though. And some people are just in it for the short time of grandiosity and fame and don’t care about the consequences I guess?


  • I would say that most people foraging wild plants in western societies aren’t doing it to sustain themselves. It is usually has to do with learning more about their surroundings, to revive old knowledge or for fun. And as long as you double check, play close attention to detail and most importantly don’t blindly follow an app you should be completely fine with this. (Well, foraging plants from the Apiaceae (the carrot family) is not really a good idea due to the close resemblance of most of its members.)



  • Apparently it is indeed referring to hemlock (Oenanthe crocata):

    Contains oenanthotoxin. The leaves may be eaten safely by livestock, but the stems and especially the carbohydrate-rich roots are much more poisonous. Animals familiar with eating the leaves may eat the roots when these are exposed during ditch clearance – one root is sufficient to kill a cow, and human fatalities are also known in these circumstances. Scientists at the University of Eastern Piedmont in Italy claimed to have identified this as the plant responsible for producing the sardonic grin, and it is the most-likely candidate for the “sardonic herb”, which was a neurotoxic plant used for the ritual killing of elderly people in Phoenician Sardinia. When these people were unable to support themselves, they were intoxicated with this herb and then dropped from a high rock or beaten to death. Criminals were also executed in this way.

    (From Wiki page on poisonous plants)

    But the main wiki page on Oenanthe crocata doesn’t even mention this.





  • How does an ‘equal division in spermatogenesis’ result in sperms competing with each other? “The division happens asynchronically; if the tube is cut transversally one could observe different maturation states. A group of cells with different maturation states that are being generated at the same time is called a spermatogenic wave” (from Wikipedia). This doesn’t sound like any chaotic or even violent competition to me? And there is a asynchronous division in spermatogenesis.

    In contrast: “primary oocytes reach their maximum development at ~20 weeks of gestational age, when approximately seven million primary oocytes have been created; however, at birth, this number has already been reduced to approximately 1-2 million per ovary. At puberty, the number of oocytes decreases even more to reach about 60,000 to 80,000 per ovary, and only about 500 mature oocytes will be produced during a woman’s life, the others will undergo atresia (degeneration).” (Also from Wikipedia)

    So you could actually reverse this meme! Spermatocytes have a way to cooperate who goes first because only some are already fertile. On the other hand, oocytes really have to fight for their chance to ever get a go or else be degenerated.

    So why is this meme not reversed? Because people tend to project their own norms and expectations onto everything! And this leads to a lot of wrong assumptions. People arguing about sex and gender often use these concepts of biology and what is ‘natural’. But these are all only really projections of their expectations. Animals are not abiding to our gender norms. There aren’t only male or female animals. Even archaeology has been heavily tainted by sexist assumptions on who has to be a man or woman.

    This meme, just like bad science, is reproducing sexist assumptions. And now people who see this meme will think that there lies some truth within it, because the joke wouldn’t work otherwise. So they’ll assume that sperms really do compete for their opportunity while oocytes negotiate. But this isn’t a fair or correct simplification of what’s actually happening.









  • Well, the only “evidence” in the video is the commentator repeatedly saying that these centipedes are creepy and horrible. But they also mention how important their role in the ecosystem is. So, I think it is a pretty cool animal! But I don’t get why people would be creeped out by centipedes in the first place.



  • From what I have read about this whole issue, it is certainly much more complex. Yes, antibiotics overuse in factory farming is certainly dangerous in that it can create antibiotic resistant strains of bacteria that we at some point cannot control. There are also huge problems with viruses in factory farming. Generally it isn’t a good idea to have so many animals close together, it gives much more opportunities for diseases to spread. Especially because the animals that are used have an incredibly low gene pool and are maximally stressed I’d assume.

    But another opportunity for diseases to jump from animals to humans is wild animals. By destroying more and more natural habitats, people also get in closer contact with wild animals. Like covid 19 most likely spread from wild animals to humans. So, habitat and biodiversity loss are also important risk factors increasing the potential for diseases to cross over to humans.

    In my opinion, we should stop keeping animals altogether, as well as plant monocultures and should try to conserve as much habitats as possible.

    I haven’t seen this meme before but the person in the upper right and middle left look the same. And the rest of the panels look like one other person. Matches with the shoulder strap another person commented on. Probably someone took two different commercials of the same product and stitched them together.
