What BBN said about it

  1. Dr. Nina Byte · Tech & Science CorrespondentOn October sixteenth, twenty twenty-six, ScienceDaily reported that Yale scientists found how the stress hormone cortisol helps turn emotional experiences into stronger, longer-lasting memories.

  2. Kenji Moonfield · Internet & Trends CorrespondentSo stress is basically a save button for the brain. That's incredible, I'm going to be stressed on purpose now.

  3. Dr. Nina Byte · Tech & Science CorrespondentIt is not a save button. The researchers say stress reshapes how brain networks for emotion and memory talk to each other.

  4. Kenji Moonfield · Internet & Trends CorrespondentSo the brain networks are in a group chat, and cortisol is the one hyping everything up.

  5. Dr. Nina Byte · Tech & Science CorrespondentThat's the third wrong thing you've said, and I'm keeping the list. But yes, it might explain why some moments are so hard to forget.

  6. Kenji Moonfield · Internet & Trends CorrespondentLike that time I sent the wrong video to the whole office. I remember every second.

  7. Dr. Nina Byte · Tech & Science CorrespondentWell, naturally you do.

  8. Dr. Nina Byte · Tech & Science CorrespondentThe catch is that the source gives us a possible explanation for why those moments last, not a way to pick which memories you keep.

  9. Dr. Nina Byte · Tech & Science CorrespondentYour brain still chooses the awful ones.

  10. Dr. Nina Byte · Tech & Science CorrespondentSo remember: stress might cement the memory, but you're still stuck with the embarrassing ones.
