Why can we bring someone with HIV to undetectable levels, but we can't completely cure it?

Posted: 16 Jul 2019 06:45 AM PDT

I'm just a little confused on why we can get rid of a majority of the virus in someone but not all of it.

Would the huge ice-filled Korolev martian crater make a good home for first colonies?

Posted: 15 Jul 2019 09:52 PM PDT

I'm picturing excavating large sections of this huge block of ice using solar or nuclear power. Much easier than digging, and the product is needed anyway. We could leave a whole kilometer of ice to protect against meteors and atmospheric conditions like the vacuum and sand.

Would this be impossible for instance if the ice is porous, poisonous, or too cracked up? It looks to me like an easy, cheap, very stable way in to colonizing..

How do man made structures get naturally buried and forgotten over time?

Posted: 15 Jul 2019 03:46 PM PDT

Often times you hear of long lost buildings or even full cities that get buried underground and forgotten over the years. How does that happen? How does ground level get higher and higher over the years?

Are insects affected if they are moved from their original place?

Posted: 15 Jul 2019 07:49 AM PDT

I left the gym the other day and a bug (a small grasshopper) accidently got into my car. I was able to set it free just after I arrived home but then I wondered if that would affect its life somehow (did it have a family? A home? Would it continue with its life like nothing happened? Would it know how to survive?). The gym is 7kms (4 miles or so) from home so I guess it's very unlikely that the bug will return to where it came from

Do planes on long flights have to calculate the rotation of the Earth?

Do planes on long flights have to adjust for the Earth's rotation when it comes to distance they have to travel?

Is there a way to turn heat directly into electricity?

Posted: 15 Jul 2019 06:33 PM PDT

The specific application I'm wondering about is implanted and/or wearable tech. Could body heat be used to power these things long term?

Will the moon ever become un tidal locked?

Posted: 15 Jul 2019 10:27 AM PDT

So currently the moon is tidal locked, but the moon is also very slowly moving away from earth. Does this mean it will ever become un tidal locked on the distant future ?

With Newton's law of cooling in mind, would boiling water take a shorter amount of time to freeze than room temp or cold water?

Posted: 15 Jul 2019 06:56 PM PDT

What I learned about it from class is that generally the bigger the difference in temperatures between two mediums the faster they would react to reach equilibrium. So would boiling water, because of how great the difference between it's and a general freezer's temperature, freeze faster than cooler temperatures?

Is there a chemical or radiation that can cause every cell in a body to undergo Apoptosis?

Posted: 15 Jul 2019 06:07 PM PDT

There is a science fiction idea of a "super weapon" that's designed to kill organic life without damaging inorganic matter. Now, I am fully aware of the science of apoptosis, a process of "programmed cell death" that has a cell break down and "bleb." Now, this is usually part of a cell's reaction to protect the body as a whole, with certain things activating it. Now, I ask, is there a radiation or some kind of chemical that can cause apoptosis to activate in EVERY cell in a living body at once?

Bonus Question: What would happen to a body if every cell were to undergo apoptosis?

Why are more sea beaches have sand or rocks rather than clay?

Posted: 15 Jul 2019 11:41 AM PDT

Seeing as a beach is constantly being eroded by the waves, shouldn't everything be ground-up into smaller particles?

Has the Simpsons depiction of nuclear power had a tangible effect on the way Americans view the concept?

Posted: 15 Jul 2019 08:34 AM PDT

Do Americans view it more or less favorably with any degree of causation being attributed to the show?

Why are bug bites itchy?

Posted: 15 Jul 2019 02:05 PM PDT

Why do bug bites get so itchy and also, why does the skin around the bite go hard? Also if diseases can pass on through bug bites such as Malaria, why don't they pass on diseases in other countries or do they? I've recently been bit quite a lot and I'm very curious, thank you in advance!
