And that would be entirely acceptable, perhaps even desirable, since it would be only be verifying the quality of the Ink rather than locking out competition even when the competition has a product of sufficient (or even superior) quality.

Significantly less macroscopic life. If it's a very small body it is likely to dry up eventually, so that rules out long-lived fully aquatic lifeforms. Even predatory insect larvae (for example, dragonfly larvae) have a much longer de

It is certainly true that mosquitoes need still water to breed, their larvae being aquatic. Depending on the species, this can be anything from a pond to a tiny puddle or even a thimble-full of water in a bromeliad. The main requirement i

If I understand correctly, when the author say "hierarchical rank" he means that the rank (let's call it R) is larger for people at the top of deeper hierarchies, and that seems to be confirmed by the graphic in Figure 5. Any

Unreinforced concrete has its advantages... this tower still stands after 140 years, and so barring an earthquake it can't withstand it is likely to continue to stand for hundreds more years. Steel-reinforced concrete is considered to

Fascinating. This may give us a way of empirically comparing the processing power of biological vs digital neural networks. Just make them play pong against each other and see who wins!

Just because something is "synthetic" doesn't mean it's toxic. Plastics, or rather the additives used to make plastics soft, flexible, water-repellent, etc., are now known to have a specific set of toxic (or endocrine d

Probably not, actually. According to that Wikipedia page you linked the Prometheus Society has only 120 members. Since they accept people who are in the top 1/30,000th in terms of IQ, therefor there are 8 billion / 30,000 = 266,

ZeroTier and Tailscale, yes, maybe. Nebula, as I understand it, no... it's a fully Open Source project, the mesh is P2P, and the "lighhouse nodes" which serve as tunnel end-point directories, you run yourself as well. There
