Reply to comment by [deleted] in Around 550 million years ago the earth's magnetic field almost collapsed, but then strengthened a few million years later. Scientists say this may have been due to the formation of the inner core. But why exactly would that cause the magnetic field to get stronger? by somethingX
No it wouldn't make sense. Theia happened 4.5 billion years ago making the whole planet molten

Going all the way to Callisto to mine it still wouldn't make sense.
Uranium is actually one of the more common elements in the crust. It's just about finding an economically viable concentration and going to Callisto isn't. Aside from the fact that the surface is covered in Ice

The energy cost to bring that uranium back is immense though.

No, you'll need to compare measurements to see what the other did.

If you're partially aerobraking you might as well do it fully rather than trying to catch up to the ISS

The article says it rejects the sterile neutrino hypothesis quite strongly, although it doesn't say it rules them out altogether from existing.

Sterile Neutrinos as dark matter has been ruled out, an experiment running next to a reactor has found no sign of them.

From looking about articles on it seems that the virus doesn't survive for that long normally and the main form of transmission is from aerosolised droplets. The labs used unrealistic amounts of virus compared to real world settings
