As luck would have it, one of the major obstacles to the terraforming of Mars is the deeply toxic nature of its soil (or rather, regolith) caused by an abundance of perchlorates. From the paper, Perchlorate on Mars: a chemical hazard and a resource for humans Perchlorate (ClO4−) is widespread in Martian soils at concentrations between 0.5 and 1%. At such ...

They can see UV, although... If they are to see details of size $0.3 \ {\mu m}$ while holding an object close to their face (let's say $15 \ cm$ away), they require an angular resolution of $\theta_c=2 \times10^{-6} \ \text{rad}$. Smaller $\theta$ means better resolution. The diffraction-limited resolution of a a circular aperture (like an eye) is  \theta=...

Looks pretty believable. Couple of things I noticed when looking at particular regions. Note on SE.Australian currents. As whole landmass is located further south, I think you more likely to have cold currents creeping up the SE between NewZealand and Aus. Same as in your S.America Falklands currents. Rather than keeping the same pattern of warm currents ...

This is a topic that is of interest in the real world. Amputees have different nutritional needs compared to what they had pre-amputation. TL;DR after the whole healing process amputees generally need only to adjust for weight, but not for the actual weoght they have. I found an article in the American Journal of Clinic Nutrition with a proposal for the ...

You shouldn't need different food so long as you can still actually eat food since your organic parts don't require anything different. To be able to continue to eat you would need the stomach and intestines just get replaced with artificial equivalents. If they were instead just removed, you would have to consume some special formula instead and still need ...

I'll repost what I told you on Reddit, as this looks like the same map: For the most part the climate won't be any different as no major currents are interrupted outside the Arctic, but the change there won't make it any warmer so it'll still be Köppen ET/EF. Where you've added large inland bodies of water expect the Köppen classification to distort the ...

Fog does not stay together. Like a robot servant who turns off the light when you leave the room, the utility fog would slump into inert particles when not needed. Everything in the room made of fog would dissipate into drifts on the floor. What would be left would be a non-fog AI - some Alexa like Argus entity which watches everything and knows where its ...

I would say the fog stays together using magnetic flux pinning. This link explains the phenomenon: https://en.m.wikipedia.org/wiki/Flux_pinning Now I don't know all the equations and stuff, because I'm but a layman but in principle it's when a superconductor gets enveloped in a magnetic field it shields it from all other magnetic fields and causes a ...

Hacking Given that the fog is remotely controlled, it will be very susceptible to hacking. You might wake up one morning to find that a prankster has turned your bed into a skip, complete with garbage. Or your house might now be in the middle of the street and look like a Swiss chalet complete with snow but no bathroom. Creativity As in virtual worlds, some ...

We have tons of machinery which has the very same "issue" when they are not used: printers, computers, cars, ships, rockets. Basically everything! In your case the utility fog will still need to have a power supply to stay idle. If that power supply happens to be a RF source, the emitter of the can be configured in such a way that the power supply ...

boolean permanent = true It seems a rather trivial question. You've made something that can shape, colour and add properties (flex, conductivity, etc.) to itself to your desire. How difficult would the next step be that you consider an object finished or permanent and the fog to obey? Probably you barely need to spare the thought. Only if you would actively ...

This question is (unintentionally) fallacious. If cetaceans were intelligent in your story, or even super-intelligent, what would it mean? You want a story where they've been secretly doing "intelligent things" (even if these things amount to little more than "intelligent thinking"), and humanity eventually realizes that it is so. If ...

Alien cetaceans show up. Star Trek IV: The Voyage Home /To save Earth from an alien probe, Admiral James T. Kirk and his fugitive crew go back in time to San Francisco in 1986 to retrieve the only beings who can communicate with it: humpback whales./ In the movie, aliens show up looking for their whale kindred. Humans had wiped them out some time ago ...

Multiple Dimensions of Intelligence Humans are obviously superior to most animals in the kind of intelligence that concerns the manipulation of your environment with tools. However, we have expanded beyond the concept of a one-dimensional IQ to terms like logical, interpersonal, or artistic intelligence. Maybe its just one of these facets where your ...
