How does the goverment control scientific reseach

science is nothing without funding

Explanation:

Well Science in the US is highly a political affair. Scientists need funding for research, so they usually have to obtain grants from people who have the means to spare it. In many cases that means people who are involved with the government, or have close ties to it.

So scientists find themselves having to play off partisan politics in order to secure the funding they need for their research. Many times they also find that their research will inevitably get skewn to meet the original funders own ends.

Mostly what I have said is commonly known. However I am in school, and deal with scientists and doctoral researchers who have expressed and validated similar experiences.
