  • One-Handed Life
    Scientists with the NASA Astrobiology Institute have created self-replicating molecules that produce only "left-handed molecules or only "right-handed molecules.The findings may help explain why life is based on left-handed amino acids.

  • Jurassic Spark: Early Ancestor of Mammals Found
    What is nearly 200 million years old, furry, weighed less than a paper clip and scurried beneath the feet of dinosaurs? A team of fossil-finders, led by researchers at Pittsburgh's Carnegie Museum of Natural History, suggest the answer may include one of your relatives -

  • Life’s Baby Steps
    Billions of years ago, amino acids somehow linked together to form chainlike molecules. Now scientists have discovered what may be a key step in this process - a step that has baffled researchers for more than a half a century.

  • Oily fossils provide clues to the evolution of flowers
    A team of Stanford geochemists has found evidence that flowering plants may have evolved 250 million years ago - long before the first pollen grain appeared in the fossil record.

  • TNA World
    DNA is the building block for life on Earth. But it is a highly complex molecule, and could not have arranged itself spontaneously. What did it develop from? Astrobiologists examine possible ancestors of DNA: nucleic acids called PNA, p-RNA, and TNA.
