Panel Says http://kajx.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://kajx.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.
