As I always harp, do things like research because YOU like and love the science, doing experiments, learning that field, etc. NOT to check off boxes. Box-checkers are extremely transparent, especially in interviews, whereas another person with the same ECs with actual true passion will shine.
Bottom line for research: If you did it, fantastic. If you did it and don't have a publication, still fantastic.If you did it and have a publication, brilliant. If you didn't do it, it's not a death sentence.
