no, unless you are a university or other educational institution, registration of such domains are not available to the general public, i believe you have to validate that you are an actual institution in writting to either internic or another domain holding firm in order to gain one.
Search "domain name registration" at Google. Lots of options will appear. Some are as low as $8-$10 per year (if you register for more than one year), some are as high as $35 per year. Shop around. But it's pretty easy to set up with a credit card.
