<jats:title>There Goes the Neighborhood</jats:title> <jats:p> A mass-accreting black hole in steady-state cannot produce more radiative energy than its gravity can counterbalance, achieving what is known as the Eddington limit. However, mass accretion can also be converted into kinetic energy via mechanical outflow. Using x-ray observations, <jats:bold> Soria <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6177" page="1330" related-article-type="in-this-issue" vol="343" xlink:href="10.1126/science.1248759">1330</jats:related-article> , published online 27 February; see the Perspective by <jats:bold> <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6177" page="1318" related-article-type="in-this-issue" vol="343" xlink:href="10.1126/science.1251944">King</jats:related-article> </jats:bold> and the cover) identified a compact shock-ionized radio/optical nebula in spiral galaxy M83, powered by a black hole, inferred that the black hole emits a spherical wind that exceeds the Eddington limit tenfold and succeeded in estimating it's mass in the range of 5 to 15 solar masses. It is possible that rapidly accreting black holes have greater influence on their host galaxy than once appreciated. </jats:p>

<jats:title>Ultrafast Manipulation</jats:title> <jats:p> Multiferroic materials commonly show both magnetism and ferroelectricity, such that the electric field can be used to manipulate the magnetic order, and vice versa. <jats:bold> Kubacka <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6177" page="1333" related-article-type="in-this-issue" vol="343" xlink:href="10.1126/science.1242862">1333</jats:related-article> , published online 6 March) used a strong terahertz electromagnetic pulse in resonance with an electromagnon—an excitation based on both electric and magnetic ordering—to control the spin dynamics of the multiferroic TbMnO <jats:sub>3</jats:sub> on a sub-picosecond time scale and induce the rotation of the spin-cycloid plane of the material. </jats:p>
