Study can't confirm lab results for many cancer experiments
CTV
Eight years ago, a team of researchers launched a project to carefully repeat early but influential lab experiments in cancer research. They recreated 50 experiments, the type of preliminary research with mice and test tubes that sets the stage for new cancer drugs. The results reported Tuesday: About half the scientific claims didn't hold up.
