  • So the general pattern is that temperate forests are increasing, but tropical forests are declining (presumably due to climate change).

    Given that tropical forests are richer in species diversity and biomass per unit area, the discrepancy is probably greater than the changes in area suggest.

  • MediaWiki’s probably overkill for basic wiki functionality, but I use it for the sake of Semantic MediaWiki and associated extensions. But SMW has more of a learning curve, so it might not be worth it for a casual-use wiki.

  • That was my first assumption on reading the title, but the article mentions two other things:

    • The male-gene bias apparently persisted for subsequent generations after the initial human/Neanderthal pairing: male children of mixed ancestry had more offspring than their female siblings
    • In Neanderthal communities, the bias was reversed (i.e., more human DNA was retained in the X-chromosome female line.)
  • If the two species were biologically incompatible, modern human DNA should have been missing from Neanderthal X chromosomes as well. However, the analysis revealed that Neanderthal X chromosomes had a 62% excess of modern human DNA compared with their other chromosomes – a mirror-like reversal of the distribution of Neanderthal DNA in human populations.

    I dunno—isn’t that still consistent with a scenario where there’s a specific incompatibility between some gene on the Neanderthal X chromosome and a human gene on some other chromosome?

    Otherwise you have to have two parallel-but-opposite trends in human and Neanderthal societies, where human societies favor male offspring of human/Neanderthal unions, but Neanderthal societies favor female offspring.

    (Maybe this is addressed in the full paper—I don’t have access.)

  • Humanity? Sure.

    Human institutions? Less and less.

  • If you open the box, he might not have a cat. But before it’s opened we can be 100% certain that it contains a superposition of cat and non-cat.

    Do you want to be responsible for the loss of his uncertain cat?

  • He had more waves than he knew what to do with.

  • The point of Maxwell’s demon is that there’s an intimate connection between thermodynamic entropy and information: increasing entropy reduces information, but adding information can reduce entropy.

    I think what they’re getting at here is that the enzyme’s state preserves information about its recent past which it then uses to reduce entropy the way Maxwell’s demon does.

  • the researchers constructed a theoretical model where the transient increase in motility served as a "memory" of the enzyme's immediate past reaction event. The enzyme used this information to leave the product molecules, thereby eliminating the probability of the reverse reaction.

    So if I’m understanding correctly, just after an enzyme catalyzes a reaction it “remembers” that the products it just produced must still be nearby and knocks itself away from them?

    That looks more like an encoding issue than AI slop (or maybe an AI that was trained on a mix of normal and Base64-encoded text).

    Or even someone just dragging two fingers around on a keyboard.

  • I did read the article, and I generally agree with you—but I’d add that the most important thing is global biodiversity (or even, the ability to increase global biodiversity on an evolutionary timescale going forward).

    An invasive species might have a negligible effect on the biodiversity of the local ecosystem (or even a positive effect, if it’s replacing the functionality of a previously-lost species), but if you add the same species to every similar biome in the world, then each of those locations loses the opportunity to diversify in a different way. (And it increases the odds that a pathogen will adapt to the homogenized ecosystem and decimate every instance around the world simultaneously, with no unaffected ecosystems left to restore lost functionality.)

  • amplifying H-Neurons’ activations systematically increases a spectrum of over-compliance behaviors – ranging from overcommitment to incorrect premises and heightened susceptibility to misleading contexts, to increased adherence to harmful instructions and stronger sycophantic tendencies. These findings suggest that H-Neurons do not simply encode factual errors, but rather represent a general tendency to prioritize conversational compliance over factual integrity.

    I wonder if the same tendencies are associated in humans—and if so, is it something LLMs learned from humans, or is it a consequence of the general structure of neural networks?

  • One of the many debated claims about Pirahã is that female speakers can’t use the phoneme /h/, always substituting /s/ instead.

  • If they’re working on a problem that can be broken into multiple loosely-coupled parts, or that requires exploring a very large conceptual space.

    Is it likely that we’re underestimating the extent of metamorphosis in the fossil record because we’re mistaking different stages of the same organism for different species?

    I wonder what humans do when they’re not taking showers. And where does all this water come from? And how did I become sentient?

    Maybe "CAESAR STABBED IN BACK BY BRUTUS AND CASSIUS" was just an ancient clickbait headline, and the actual event was a minor policy dispute instead of a literal assassination.

  • Biodiversity @mander.xyz

    Emerging niche clustering results from both competition and predation. (My takeaway: more species can coexist in an ecological niche if they have distinct predators.)
