I don't mean to be rude, but I think your question is based on several falsehoods that have been addressed in some form or another, so I'll try to address them one at a time.
Do scientists look down on "believers"?
First of all, as a physicist, I don't believe scientists do look down upon or denigrate "believers" or religion per se, and yes, many scientists are believers. What scientists do object to is some of the behaviour of a few religious people, such as insisting that religious beliefs be taught in a science class (this was a criticism of Alan I. Leshner, the CEO of the AAAS, the society that provided that poll you reference). In fact, I would assert that scientists specifically don't tend to target religions, but rather a handful of people from those religions that try to affect science in some way.
I can't find anything that definitively links scientists with denigrating religion (aside from people like Hitchens, Dawkins), but if you look at the survey you reference, only 40% of people view clergy members as having a positive impact on society (versus 70% for scientists), so it may be a cultural thing in the US. (Yes, I realize clergy does not equal church or religion as a whole, so take this whole argument with a GIANT grain of salt).
Most Scientists are believers
As pointed out by Mozibur Ullah and Discrete lizard, this is not a straightforward statement to prove. First of all, the US is quite religious compared to many other places. In a survey, 69% of Americans rated religion as important, compared with just 42% in neighbouring Canada (Note 1; yes I realize it is Wikipedia, feel free to find other sources).
That poll you quote is far from definitive, 51% does not mean a majority, it means, probably a majority (Note 2). The actual number is 32% +/- 2.5% 95% confidence interval (CI) for people that believe in god, plus 18% +/- 2.5% 95% CI for people that believe in some higher power. Meaning if you ran that same survey 20 times, you would get values outside that region on the one of those surveys (on average). This only means that when you add these together you get approximately 50% of scientists believe in god or some higher power, with the caveat that it might be a majority by a few percent, or it might be a minority by a few percent.
If we start including scientists from much more religious countries such as middle-east or Latin America, that number skyrockets to 70-99 %. I am unsure what the numbers are in Europe and Asia
Where are you getting these numbers from? Also, a LOT of science is done in Europe and Asia, very likely more than the US, it it is pretty important to consider those. Having lived in Latin America, I can tell you that not a lot of science goes on there, and neither does a lot happen in the Middle East (although it is growing in the Middle East). When you add on Europe, Japan, China, Russia, etc, I strongly suspect that that number will start to trend in one direction or another, but I doubt it would ever "skyrocket".
Science and Religion are NOT in Conflict
You state that you "know that science and religion are NOT in conflict", that really depends on your religious views. For example, if you religion depends entirely on the Earth being exactly 1000 years old and a geologist tells you that the Earth is more like 5 billion years old, then yes, they are in conflict.
That isn't to say that it is always in conflict, for example you may believe in the the Big Bang, but that it was created by a deity.
The reality science and religion are different at a fundamental level. Religion has a set of rules, and facts that affect ones world view, much of which must be taken on faith. Science on the other hand, aims to take as little on faith as possible, and instead requires us to update our world view. What we take on faith is usually stuff that we don't have time to learn enough about. For example I know very little about the Big Bang, but I know that many researchers have spent their lives doing research and I know a little bit about the most important points, so if I encounter someone who has a strong argument against one of those points, I may not be able to answer it properly, but I take it on faith that it likely has been answered (admittedly, it could be an open question in that field).
Asking whether or not science and religion are compatible is kind of like asking if music and potatoes are compatible. Aspects of the two may clash, or the may not; aspects of the two may even coincide.
Hitchen's Patent and Scientists agreement
First of all, people like Hitchens (and Dawkins) are extremely polarized people, I'm sure if you spent a bit of time looking you could probably find people that have similar views as Hitchens without the attitude. I almost feel sorry that your introduction to atheism was Hitchens and not Bill Nye or something.
Second of all, I have never encountered this argument that non-scientists like Hitchens claim a patent on science, and even if they did, I would say that is certainly untrue. Science, by it's very nature, is everywhere and for everyone, should they choose to explore it (provided they can afford it; this is perhaps another similarity that science has with some religions).
Third, I think your "scientists themselves seem to disagree with them" statement is probably in reference to your poll, but I've already addressed that for the most part. I would just like to reiterate that science and aren't inherently compatible or incompatible.
