  • Shining Light on Life’s Origin
    When ultraviolet radiation was more intense than today, and the early Earth had a mix of nitrogen-rich molecules, how did this primordial soup get cooked? And how did it not burn? Scientists are asking the question: How did the fittest biomolecules survive, before life itself

  • The Pull of the Recent
    While the count of species has gone from a few to over thirty million, it has long been wondered whether this apparent diversity involves fossil biases: more modern fossils survive to be classified.

  • Army Ants: No Evolutionary Picnic
    NASA's Jet Propulsion Lab has explored the possibilities of using an ant colony metaphor for space exploration. Recent Cornell scientists have shown that the dispersal success of army ants seems to far exceed evolutionary expectations.

  • Primordial Recipe: Spark and Stir
    No single experiment, according to Carl Sagan, has done to convince scientists that life is 'likely abundant in cosmos' than work fifty years ago by then graduate student, Stanley Miller. This week celebrates his milestone publication, and Astrobiology Magazine interviewed him about his work and

  • Big Red Boosts Biodiversity
    As hard as it might be to surprise those who have collected and classified the estimated 30 million species on Earth, deep sea divers off the coast of California have added a new species to the planetary tally.

  • Water: The Molecule of Life
    Philip Ball, author of "Life's Matrix: A Biography of Water," says that liquid water is essential for the kind of delicate chemistry that makes life possible. In an interview with Astrobiology Magazine, he discusses his thoughts on the role of liquid water for life on

  • Dinner with Darwin
    "Which 5 historical figures would you invite to dinner, and how would you seat them?" In mock interview format, today's feature in this "Dinner With..." series, excerpts answers from Charles Darwin's Origin of Species, as an initial historical 'guest' to sit down and discuss how

  • Redundant Evolution
    Gene duplication in plants has led to new species, but scientist haven't known why and when such "carbon copies" of genes come to exist. A University of Georgia study published in the journal Nature tries to uncover why this divergence happens.

  • Beaming a Lifeform Musically
    This week's celebrations for the fiftieth anniversary of the DNA double-helix highlights the rapid advances in genetic sequencing. These breakthroughs have allowed comparisons previously unavailable to those scientists who try to understand how such a complicated structure as DNA might have evolved.

  • Life’s Working Definition
    Finding life elsewhere in the universe depends on knowing when you see it, according to Colorado professor Carol Cleland. She gives a view of how life might not need a working definition as much as a theory of life -- at least until scientists
