Scientific Explanation
Laboratories worldwide attempted reproduction but no one could replicate the STAP phenomenon. Genetic analysis of remaining samples revealed that what was called STAP cells were existing ES (embryonic stem) cells.

The former genius idol who promised rebirth through stimulus
A late-teens former genius idol. Promised "anyone can become pluripotent cells with a little stimulus!" but secretly had other cells (ES cells) hidden. No one could reproduce the results, and genetic analysis revealed contamination with existing ES cells.
Announced from RIKEN. Worldwide reproduction failed, ES cell contamination discovered, paper retracted.

Spectacular announcements and attention do not prove scientific validity. No matter how "dreamy" a discovery, without reproducibility it's not science.
Catchphrase“With just a little stimulus, you can be reborn!”
Silicon is the foundation of lab equipment. The STAP controversy re-emphasized the importance of experimental environment management.
“STAP細胞は、あります!…ありました。…あると思ってました”
“ちょっとの刺激で生まれ変わる!酸性溶液に浸すだけ!”
“…あれはES細胞だった。最初から。気づかなかった…のか、気づかないフリをしたのか”
“科学は、「信じる」だけでは成立しない”
“再現性、再現性、再現性。…あの言葉が頭から離れない”
Um... STAP cells... exi-... no, I can't say that line anymore...
Personality changes with a little stimulus? ...Isn't this app suspiciously STAP-like? (self-deprecating)
Stappy: "Silicon... lab equipment is important, isn't it..."
Silicon: "Of course. Semiconductors and lab equipment both live and die by purity and contamination control."
Stappy: "ES cells were mixed in... contamination..."
Silicon: "Whether intentional or accidental, experimental environment management is the absolute foundation of science."
Stappy: "...If I could start over... in a clean environment..."
Silicon: "Starting over and being honest are the most important attitudes for a scientist."
"Being noticed" and "being correct" are completely different. I was noticed. But I wasn't correct.
Showing dreams isn't a sin. But hurting people with false dreams is... unforgivable. Reproducibility alone is science's promise.
