But it's not a "hitherto conjectured form of symbiosis". It's just another example of facultative lichenization, which has already been observed in species quite widely scattered across the fungal kingdom. That to me doe

I'm skeptical that this discovery amounts to a "new type of coexistence". Fungi that are facultatively lichenized (having growth forms that include or exclude algae) have been known about for a long time, as have various stag

It's woefully wrong for something in the primary literature. Yes, I understood what information they were sloppily failing to be precise about. If I were refereeing this paper I'd insist on a correction.

SALT_VERSE just uses still images generated by DALL•E-2 and Midjourney. They're animated using techniques that have already been around for a long time: panning around and zooming in and out of a larger frame, fake raster-to-3d effects

The biological term "symbiosis", by itself, in the strict sense, doesn't imply a benefit for both parties, it just describes a persistent and physically close association between two species. Hence parasitism or commensalism

Psilocybin-producing mushrooms are widely dispersed across the clade of all other true mushrooms and their genomes clearly show there is no great mystery about their evolutionary history or relationships to other fungi. Modern phylogenetics

Tunicates evolved long before animals that you would recognize as typical vertebrates. In their free-swimming larval state, tunicates do have a "notochord", or nerve chord, running along their head-tail axis. This structure is a k

OK, I looked at some piano roll layouts in DAWs, and found examples with equal spacing between semitones, you're right. I looked at some music mapped onto this layout. The layout allowed for speedy recognition of lone intervals and sim

It makes sense in the context of tonal harmony. An octave is the interval between the 1st and 8th notes of a major or minor scale. I.e. a major or minor scale repeats itself (at double the frequency) every eight notes. A major third is the

I don't trust you. You're just used to thinking in terms of the piano keyboard. As I said before, the distance between two adjacent white keys on a piano roll could be a major second, or it could be a minor second. In other words

A piano roll visualization gives a somewhat more immediate depiction of intervallic information. But it isn't absolutely proportionately spaced, it's mapped to keyboard topology. Two neighboring white keys could be a major or mino

Correct, DNA is just one element of a complete organismal informatics, you need vastly more than just the genome sequence to ressurect a species. Relatively simple microbes, or recently extinct mammals where you have a semi-plausible scheme
