Cold Fusion Strikes Back

It's been derided as a far-fetched myth, but a recent demonstration of cold fusion in Japan has proven...not much, really. For those who don't know, cold fusion is the idea that it's possible to create nuclear fusion at room temperature, producing massive amounts of energy with almost no waste. Japanese physicist Yoshiaki Arata of Osaka University claims to have demonstrated it. The process he used is very involved and technical, but the results were rather underwhelming. It's possible that the cold fusion case has been cracked, but you have to wonder why Yoshiaki chose to introduce his groundbreaking discovery at a cheesy photo-op instead of publishing his results in a peer reviewed journal. Other scientists will try and duplicate the experiment, but I wouldn't hold out hope for this just yet. Now perpetual motion, on the other hand--that's some promising pseudoscience! More details here.
