Looking through field glasses

In research, one is always forced to look objects through field glasses.
During looking the ocean through it, you may find sardines. But if you persist in the view, you will miss something exciting.

Previously I and coworkers identified a gene. We showed that the gene product has a function in a pathway; however, later studies using knockout mice revealed that this gene is important for another metabolic pathway and being responsible for a disease. We got sardines but missed a whale.

Now, I am trying to identify functions of novel genes. I would catch a big one this time without any bias.
