In another step toward understanding the origin of Earth's biological molecules, two independent laboratory experiments have produced amino acids--the building blocks of proteins--by simulating conditions in icy, interstellar space.
The results, published in the March 28 Nature, suggest that some amino acids could have formed in giant clouds of icy particles and then hitched rides on comets and asteroids to planets throughout the universe, says Max Bernstein of NASA'S Ames Research Center in Mountain View, Calif.
In the search for precursors to life on Earth, various researchers have created amino acids and other organic molecules in lab experiments ...
