in 1989 two scientists, stanley pons and martin fleischmann, published a paper in "nature", an important science journal, claiming to have created cold fusion. this was a very important story at the time. other scientists were not able to repeat their experiments. this is why cold fusion is not generally accepted by scientists at the moment. several dozen scientists are still working on cold fusion research. they publish in peer-reviewed journals and other academic sources regularly, but most are not convinced.
