BERKELEY, Calif., March 5 (UPI) -- Complex building blocks of life could have been created on icy interplanetary dust and then carried to Earth, jump-starting life, U.S. researchers say.
Chemists from the University of California, Berkeley, and the University of Hawaii, Manoa, say an experiment simulating conditions in deep space showed such conditions are capable of creating complex dipeptides -- linked pairs of amino acids -- that are essential building blocks shared by all living things.
