NASA: Spike In Atmospheric CO2 Related To El Nino
No one expects the machinery of progress to roll backwards, but sometimes it seems that no one is watching the speedometer (or manning the brakes, assuming any exist). Is this a fair assessment? If so, should we be worried — and what can we do about it?
In this feature, experts on technology, risk, science, policy and neuroscience discuss risk, innovation and how our values affect our conceptions of both.

After 4 billion years, the dwarf planet Ceres is still carrying a surprising amount of water weight — as much as 30 percent.
The finding, which was published in the Jan. 6 edition of the journal Science, is consistent with earlier models, and provides valuable clues to how Ceres formed.
