Only tell your co-workers your idea when your boss is there.
Try to do it yourself for your idea.
When I was in graduate school, we all have our own project.
Boss only want publication, as long as you got the result and show your boss, you can take the credit for it. There is no need to share your idea with others you don't like. Boss pay everyone to do their own job. Why should you do ther job for them? If your boss like others, he may sk you give your idea to others then, you have no choice. but at least he knows this is your idea.
