We don't use up ALL the oxygen in a breath of air.

There's certainly LESS oxygen available, but some is better than none.

Maybe a question for your family doctor and not *checks notes* a subreddit about space?

Whomever stands to gain from policing the space. A mining corp might have private security, a criminal organization might want to maintain control by eliminating other criminals. But this is a science reddit, not science fiction

Just planting seeds isn't enough. If it was a hybrid they often don't have viable offspring or the offspring are different from parent hybrid plants.

The last stalk of silphium was given to empower Nero. They knew exactly what the plant was and they knew when it was no longer being cultivated.

we don't know for sure the identity of the plant. good luck planting every seed from every archeological site in the Roman empire to see which is silphium

Islam is not bad. People of Islamic faith are, in general, not bad.

There are certainly some bad apples... Religious fundamentalist fascists governments that use Islamic tenets as an excuse to repress their people yes. Religious fundamentalist terrorists that use Islamic tenets as an excuse to perpetrate violence, yes. But these are faults of men, not Islam

Uranium. Element 92.

Since it is quite radioactive it is primarily used for nuclear fuel or nuclear weapons. Uranium isotopes with less radioctivity is used for bullets & armor. Formerly used in the glass industry to make green/yellow tinted glass

not a bomb. It's a powder form of purified uranium ,after being mined & extracted but before being refined further into fuel or enriched

I think we need to grow some full size human brains in a lab and ask them (with imaging, dissection, and every other test conceivable) before we get any real answers

Doing cool things with microbrains already

You get different mutated strains each year. You also get respiratory viruses of different types (flu, rhinovirus, coronoviruses, rsv, etc)

some people having the same illness seasonally can also be attributed to environmental or other seasonal habits (cold dry air , more indoor activities, interaction with asthma , copd etc) with seasonal temperature and humidity conditions making someone prone to respiratory infection

rip

it's a sloppy shorthand, fine as a joke but not an explanation

Fun note with structural colour: our eyes don't have any blue pigment, but we do have blue structural colour.

capsaicin is oil soluble, you want to wash with milk, olive oil, etc something oil based

some viruses are DNA based, some are RNA based

You don't need air to push off of. Rockets, chemical thrusters, and ion engines work in space because they spit out some sort of propellant, spitting out mass in one direction pushes the ship in the opposite direction

nuclear bombs also work in space, you drop nukes behind you and they can push your craft in your desired vector

once you have reached your desired speed, you don't need to do anything to keep going. you WILL need to expend energy or mass to slow down when you reach your destination

It's an unmanned flight that will ORBIT the moon, then come back and the empty crew capsule will land in the ocean.
