8:15 AM in the lab. I was running the same protocol I'd done a hundred times when I saw it—a signal that shouldn't exist, clear as anything in my data. It was there. Significant. Beautiful. Everything my thesis needed. I ran it again immediately. Different samples, fresh reagents, the exact same conditions. Nothing. Just baseline noise mocking me through the screen. Five months later, I'm still chasing that ghost signal. My advisor asks about reproducibility with that look—the one that says maybe you're seeing things that aren't there. But I know what I saw. I was trained for this. Years of failed experiments taught me to recognize real from artifact. Whatever that was, it existed for exactly one run, then vanished like it was never there. The mystery keeps me up at night. #Science #LabLife #GradSchoolLife
