Ancestral Eve Crystal Gave Life Its Left-Handedness

 A team of chemical engineers have discovered what may be the "ancestral Eve" crystal that billions of years ago gave life on Earth its curious and exclusive preference for so-called left-handed amino acids. The results are published in Crystal Growth and Design. Researchers used mixtures of both left- and right-handed aspartic acid (an amino acid) in laboratory experiments to see how temperature and other conditions affected formation of crystals of the material. read more
