And now, a U.K.-based project is enlisting the help of gardeners around the world to help test a theory that originated with one of history's greatest mathematicians, Alan Turing.</jats:p>

<jats:p>This week's Newsmaker is James Yoder, vice president for academic programs and dean at the Woods Hole Oceanographic Institution.</jats:p>

<jats:p>The National Science Advisory Board for Biosecurity is now recommending that the two controversial papers describing how researchers made the H5N1 avian influenza virus more transmissible between mammals should be made public, in full.</jats:p>

<jats:p>A government-wide committee last week quietly released new rules that require federal agencies to systematically screen funding proposals for "dual use research of concern."</jats:p>

<jats:p> A federal effort is under way to improve the nation's ability to manage, understand, and act upon the 1.2 zettabytes (10 <jats:sup>21</jats:sup> ) of electronic data generated each year. </jats:p>
