'Out of curiosity' means I'm not curious at all. Right?
Not quite.
The "out of" in "just out of curiosity" is nothing like the "out of" in "out of gas".
Instead, that "out of" means "stemming from" or "originating from" – it means the speaker is curious, and that curiosity is prompting the person to ask a question:
Just out of curiosity, how long have you two been dating?
If the person really isn't curious, but is asking the question anyway, that would start with something like:
Not that I really care, but, how long have you two been dating?
It's also worth noting that, in the phrase "out of curiosity," we are alluding to the first meaning of curiosity, and not the second (definitions from NOAD):
curiosity
1 a strong desire to know or learn something
2 a strange or unusual object or fact
Lastly, it's worth pointing out that this doesn't sound natural at all:
"We are all here to discuss our curiosities about learning English."
I think you mean to say something like one of these:
We are all here to discuss how we are curious about learning English.
We are all here to discuss our curiosity with the English language.
To explain 'in place' in simple words is something which is ready and all set to be used.
For example
Suppose you have started a new company. You have bought a place, got it furnished and in the interiors done, computers installed and even pre-hired the employees to work for it. The only thing which is left to be done to get the business going is 'installing the software or the system' via which you will be conduting your business. Now you say -
- Everything is in place except the systems. (meaning - everything is ready for the work to begin except the software system. As soon as the systems are installed the work will begin)
Once you get the software installed on the computers in your company then you can say -
- We all are raring to go about the business now that the systems are in place. (Systems are ready for work)
So 'in place' is used for the systems, methods or anything that gets the respective job started. In your example it is Enhanced Ebbola screening.
In your example (They have enhanced Ebola screening in place) the letter 'e' in enhanced should be written in capital.
Because of the letter 'e' is written in small it appears like it is a verb. But it is not a verb, it is an adjective.
So now the sentence would be --
They have Enhanced Ebola screening in place. (The Enhanced Ebbola screening is all ready to be used)
More examples of Enhanced -
- Enhanced Computer Systems
- Enchanced Security Systems
- Enhanced Battery

There doen't seem to be any semantic difference between these sentences. "My car just won't start" means my car just does not work. Speaking in this context, "won't" is usually used when we refer to an inanimate thing that we handle (Cambridge Dictionary). Another example is "the door won't open". In the sentences, both the car and the door are inanimate things started and opened by humans. As for "just", it may be used to put emphasis on the statement or to mean now, at this time. In addition, the first sentence sounds natural, especially in spoken English.
