Plagiarism and False statements are two biggest challenges in front of scientific community. Mere getting a paper published in high impact journal can not guarantee the truths of the results and conclusions. Obvious reason behind this is that editor or reviewer can not validate the reported work by redoing or repeating he experiments.
However for the academic profile's improvement or job pressure, many scientists, researchers compromise with their ethics.... So how we can evolve a system where genuinely of work can be appreciated rather than fancy false statements?
