Seems David Hambling / Wired UK broke the new story : EmDrive: China's radical new space drive http://www.wired.co.uk/news/archive/2013-02/06/emdrive-and-cold-fusion
.. The latest research comes from a team headed by Yang Juan, Professor of Propulsion Theory and Engineering of Aeronautics and Astronautics at the Northwestern Polytechnic University in Xi'an. Titled "Net thrust measurement of propellantless microwave thruster," it was published last year in the academic journal Acta Physica Sinica, now translated into English. ...
