'Life chemicals' may have formed around far-flung star

There is now even more evidence that life on Earth may have been seeded by material from asteroids or comets. Prior research has shown how amino acids - the building blocks of life - could form elsewhere in the cosmos. These molecules can form in two versions, but life on Earth exclusively uses just one of them. Now an Astrophysical Journal Letters paper shows how conditions around a far-flung star could favour the formation of one type over another.
