Comment Re:Highway lights??? (Score 1) 348

Having been driving on a UK motorway illuminated at night when all the lights have failed through a fault, it can be quite surprising and scary, as your eyes have grown accustomed to the brightness and so it suddenly looks very dark. Then again, on a dark isolated road where your eyes grow used to the dark, even dipped lights can seem blinding (especially halogens).

So I think it should be a case of all or nothing. Either all lights on or all lights off (even headlights), in the latter case, everyone could just wind down their windows and play very loud music.

Evolving Rocks 172

SpaceAdmiral notes a new study making the claim that rocks have been evolving throughout Earth's history. "'Mineral evolution is obviously different from Darwinian evolution — minerals don't mutate, reproduce or compete like living organisms,' said Hazen in a statement announcing the study's findings. 'But we found both the variety and relative abundances of minerals have changed dramatically over more than 4.5 billion years of Earth's history. For at least 2.5 billion years, and possibly since the emergence of life, Earth's mineralogy has evolved in parallel with biology,' Hazen added. 'One implication of this finding is that remote observations of the mineralogy of other moons and planets may provide crucial evidence for biological influences beyond Earth.'"
