I came up with some CSS to remove the fixed header at the top and increase the information density on the page, permanently applied using the Stylish browser add-on:

  @namespace url(http://www.w3.org/1999/xhtml);
  @-moz-document url("https://news.google.com/news/?ned=us&hl=en") {
   div.pGxpHc { display: none;}
   div#yDmH0d c-wiz.jB7svb {margin: 0;}
  .alVsqf .ME7ew .a5SXAc .CwaK9 {font-size: 0.8em; line-height: 1em;}
  .lPV2Xe {padding: 0.5em; color: #3b78e7 !important;}
  .ME7ew {padding: 0; color: #3b78e7 !important;}
  .adH5zf {font: 500 0.7em/1em Roboto,RobotoDraft,Helvetica,Arial,sans-serif;}
  .kWyHVd .hzdq5d {font-size: 1em; line-height: 1em; }
  .MLSuAf, .OEt0Bd {margin-top: 0;}
  .J3nBBd {font-size: 0.8em; line-height: 1em; border: medium none;}
  .fkWPz {display: none; margin-bottom: 0.1em; margin-top: 0.5em; font-size: 0.75em; line-height: 1em; text-transform: none;}
  .cZgiac .hzdq5d, .MLSuAf .hzdq5d {font-size: 0.9em; line-height: 1em;}
  .X20oP {margin-right: 0.5em;min-width: 75px;max-width: 75px;}
  .HzT8Gd {margin: 0 0 0.3em; display: flex;}
  .PaqQNc {margin-bottom: 0; margin-top: 0;}
  .JoEvud {line-height: 1em;}
  .FOvasf {display: none; color: #757575; font-size: 0.8em;}
  .C0oVfc {line-height: 1em;}
  .O0WRkf {font-size: 1em;}
  .jjs37b {display: none;}
  .iYiEmb {margin: 0 0 0.5em; padding: 0 !important;}
  }
