...conservationists' dilemma echoes that of many climate scientists. Do they push for the strict carbon-emissions reductions that many studies say are necessary to prevent serious global warming or do they accept weaker but more politically realistic targets? Whether it's conservation or climate change, science must often give way to statecraft...
...upon audience members to participate in International Climate Day on Oct. 24, when communities across the world will publicly demonstrate their support for the “350” movement. The 350 movement aims to influence policy-makers to adopt a global standard of 350 parts per million carbon at the United Nations Climate Change Conference to be held this December in Copenhagen.

...capable of analyzing the painting on a precise level without touching it, a Canadian forensic-art expert named Peter Paul Biro was able to identify a faint fingerprint left on the canvas. The print was then matched to one on a known da Vinci painting hanging in Vatican City. Carbon dating of the newer canvas matched the painting to da Vinci's period, and an analysis of the style concluded the painter was left-handed, another purported da Vinci trait. Taken together, the clues built a convincing argument for the painting's authenticity. (See the top 10 most expensive auction...

Better batteries will usher in the dawn of the electric...
