Ocean fertilization sparks algae bloom near Antarctica
Scientists test iron fertilization to boost phytoplankton that consume carbon dioxide. In a Nature study, eight tons of iron fed a Southern Ocean bloom, yielding 660 to 3,300 tons of algal carbon over 13 days, but fate of carbon and ecological risks remain uncertain.

Origin of life clues arise from fallen meteorite
Researchers study bits of a bus sized meteorite that exploded over Tagish Lake in British Columbia last January. About 220 tons of rock were shed. 410 fragments were later collected. Tests reveal organic molecules that may resemble the original precursors of life. Scientists trace the meteorite path to the asteroid belt between Mars and Jupiter.
