Panel Says http://wqcs.org/post/climate-change-adjustments-must-be-fast-and-large-un-panel-says A new report from the United Nations' panel on climate change says major action is needed, and fast, if policymakers want to limit global warming to acceptable levels.<p>There's an international target to control climate change: keeping the global temperature rise to just 2 degrees Celsius above pre-industrial levels — that's 3.6 degrees Fahrenheit. The <a href="http://mitigation2014.org/">Intergovernmental Panel on Climate Change</a> now says it's technically possible to meet that goal.

Panel Says Scientists Publish Recipe For Making Bird Flu More Contagious http://wqcs.org/post/scientists-publish-recipe-making-bird-flu-more-contagious The Dutch virologist accused of engineering a dangerous superflu a few years ago is back with more contentious research.<p>In 2011, <a href="http://www.erasmusmc.nl/MScMM/faculty/CVs/fouchier_cv?lang=en">Ron Fouchier</a> and his team at Erasmus Medical Center took the H5N1 flu virus and made it more contagious. Now the team has published another study with more details on the exact genetic changes needed to do the trick.<p>The <a href="http://www.npr.org/tags/146924995/h5n1">H5N1</a> bird flu is known to have sickened 650 people worldwide, and of those, 386 died.

It's a kind of pink ice ball that's way out there, far beyond Pluto.<p>Astronomers used to think this region of space was a no man's land. But the <a href="http://www.nature.com/news/dwarf-planet-stretches-solar-system-s-edge-1.14921#/ref-link-1">new findings</a> suggest that it holds many small worlds — and there are even hints of an unseen planet bigger than Earth.<p>"We used to think there's just not much out there.

One Man's Quest To Reawaken An Old Friend http://wqcs.org/post/space-thief-or-hero-one-mans-quest-reawaken-old-friend More than 30 years ago, Robert Farquhar stole a spacecraft.<p>Now he's trying to give it back.<p>The green satellite, covered with solar panels, is hurtling back toward the general vicinity of Earth, after nearly three decades of traveling in a large, looping orbit around the sun.<p>If Farquhar, a former mission design specialist for NASA, gets his way, the agency will command the spacecraft to fire its thrusters, veer close to the moon, and slip back into the spot where it was intended to be when it was launched in 1978 — and where it was when Farquhar and his accomplices "borrowed" it.<p>Bac Tue, 18 Mar 2014 08:44:00 +0000 Nell Greenfieldboyce 40923 at http://wqcs.org Space Thief Or Hero?

Blame The Helium http://wqcs.org/post/if-yellowstone-could-talk-it-might-squeak-blame-helium A huge amount of ancient helium is rising up from the rocks beneath Yellowstone National Park — about enough to fill up a Goodyear blimp every week.<p>The gas comes from a vast store of helium that's accumulated in the Earth's crust for hundreds of millions of years, scientists report in the journal <a href="http://www.nature.com/nature/journal/v506/n7488/full/nature12992.html">Nature</a> this week.<p>The helium is being released because in the past couple of million years — very recently, in geologic time — that old part of the crust has been feeling the heat from a huge volcano that is now s Wed, 19 Feb 2014 20:39:00 +0000 Nell Greenfieldboyce 39807 at http://wqcs.org If Yellowstone Could Talk, It Might Squeak.
