Robot probe Philae uploaded a slew of last-minute data to Earth Friday from a comet in deep space, before going to sleep at the end of its historic mission, ground controllers said.

Data streamed in as soon as Europe's pioneering robot lab reestablished late-night contact with its orbiting mothership, Rosetta, but its limited battery soon started wavering.

U.S.-China Climate Pact Seen Boosting Indian Efforts

This week's China-U.S. climate agreement between the world's top two polluters puts pressure on India, No. 3 on the list, to become more energy efficient and should encourage investment in renewable energy.

But the pact is also a relief for India because it acknowledges the long-held view among developing economies that industrialized nations have been emitting heat-trapping gases for many more decades and so should shoulder more of the burden for tackling climate change. Emerging economies argue they should have fewer constraints to pollute as they grow.
