Meteorite yields life origin clue

From BBC News:Meteorite

Scientists say that “bubbles” like those in the Tagish Lake meteorite may have helped along chemical processes important for the emergence of life. The globules could also be older than our Solar System – their chemistry suggests they formed at about -260C, near “absolute zero”. Details of the work by Nasa scientists are published in the journal Science. Analysis of the bubbles shows they arrived on Earth in the meteorite and are not terrestrial contaminants.

These hollow spheres could have provided a protective envelope for the raw organic molecules needed for life. Dr Lindsay Keller of Nasa’s Johnson Space Center (JSC) in Houston, Texas, told BBC News that some scientists believed such structures were “a step in the right direction” to making a cell wall. But he emphasised that the globules in Tagish Lake were in no way equivalent to a cell. The hollow spheres seem to be empty, but they do have organic molecules on their surfaces.
