  • If science journalists can stop dumbing down the titles to the point of being misleading that’d be great.

    A study found that the sea anemone, a member of the Cnidarian phylum, uses bilaterian-like techniques to form its body.

    This suggests that these techniques likely evolved before these two phyla separated evolutionarily some 600 to 700 million years ago, though it can’t be ruled out that these techniques evolved independently.

    Ok, so say that in the title. A blueprint implies instructions for making a human, which is not what they found.

    So it’s surprising that this species in the phylum Cnidarians (along with jellyfish, corals, and other sea creatures) contains an ancient blueprint for bilaterians, of which Homo sapiens are a card-carrying member.

    Again, this is not a “blueprint.” Just say they use the same mechanism as us to accomplish a similar task, it’s surprising enough on its own without needing to reach for a comparison to a human construct.

    How about “Cnidarians like sea anemones have been found to use the same molecular mechanisms as bilaterians like mammals”





  • This assumes a very narrow definition of “simulation” based on our current computational theories and technology. Nothing about the simulated universe theory says the thing being used to simulate us has to be anything resembling a game engine or virtual machine like we have today, or even something that runs on anything we would recognize as a computer. In the same way a peasant from the middle ages would not even be able to fathom a virtual machine from today due to missing entire categories of context and background knowledge, us thinking we can extrapolate our technology and simulation techniques to beings that would be literal gods to us and their technology is extremely presumptuous and vastly overestimates what we know.























  • We laugh at the people of the past for putting lead in their wine, arsenic on their walls, mercury on their skin, and deadly nightshade in their eyes. The people of the future will have plenty to laugh at us for. The chemicals we use now will be named in shocking factoids of how foolish and ignorant we were, just as we do for chemicals people used before us.

    And just as we might think the people of the past did not know any better, they absolutely did, just as we do for the chemicals we use now. Discontinuation of using a chemical comes long, LONG after science has rigorously documented its grave dangers, if it ever happens at all. People will continue to use it, and more importantly, businesses fight tooth and nail to continue peddling it, for far too long after we find out it’s deadly. Lead was known to be lethal even in small amounts as early as the Roman republic, yet the vast majority of cities today still have a non-trivial amount of lead pipes in their potable water infrastructure just like the Romans did, houses built just a few decades ago houses still used lead paint, small piston aircraft use leaded fuel to this day, and don’t forget that whole thing with lead solder being used in Stanley Cups, you know, water receptacles for drinking, because it’s ever so slightly cheaper (and some electronics enthusiasts vehemently swear by lead solder and absolutely hate how “everything is switching to lead-free nowadays and it’s slightly harder to get it to stick to the pins being soldered”).

    Basically, don’t hold your breath that we’ll get rid of any of these chemicals just because we found out they’re lethal or crippling to human health or whatever. That has never once happened in the history of humans using chemicals.


  • Because hosting it in a place with all the necessary infrastructure already in place would have made too much sense. Like, oh I don’t know, that one Brazilian city that recently hosted the World Cup and then the Olympics, both with many orders of magnitude more people attending than a climate conference. No gotta spend a fortune building brand new shit for a once in decades thing.

    How much you want to bet this is just an excuse to funnel public money into a private construction firm?
