MU researcher presents origin-of-life theory for young Earth

10-02-2007 · EurekAlert!

Scientists have been trying to find the origin of Earth's adenine and where else it might exist in the solar system. University of Missouri-Columbia researcher Rainer Glaser may have the answer. Glaser is hypothesizing the existence of adenine in interstellar dust clouds. Those same clouds may have showered young Earth with adenine as it began cooling billions of years ago, and could potentially hold the key for initiating a similar process on another planet.

  1. Exceptions prove rule of tropical importance in biodiversity
    11-07-2007 · EurekAlert!
    Even a group of shellfish that appear to violate the overarching pattern of global biodiversity actually follows the same biological rules as other marine organisms, confirming a general theory for the spread of life on Earth. The University of Chicago's David Jablonski and his colleagues present this finding in the Nov. 7 advanced online edition of the Proceedings of the National Academy of Sciences.

  2. Research reveals limitations of seismic data for mapping rock units in young oceanic crust
    01-29-2007 · EurekAlert!
    Researchers report in Nature that an approach used for years to understand the structure of Earth's oceanic crust is flawed and geoscientists will have to reconsider the correspondence between seismic data and rock units when mapping formations of young oceanic crust. The new finding alters the view of how new crust is formed at mid-ocean ridges, how heat and chemicals flow through oceanic crust and how life can exist in deep below the seafloor.

  3. A rarity among arachnids, whip spiders have a sociable family life
    03-12-2007 · EurekAlert!
    Whip spiders, considered by many to be creepy-crawly, are giving new meaning to the term touchy-feely. In two species of whip spiders, or amblypygids, mothers caress their young with long feelers, siblings stick together until they reach sexual maturity, and all mix in social groups. This is surprising behavior for these arachnids long-thought to be purely aggressive and anti-social, according to a Cornell researcher.

  4. Changing environment organizes genetic structure
    11-13-2007 · EurekAlert!
    What is the fundamental creative force behind life on Earth? It's a question that has vexed mankind for millennia, and thanks to theory and almost a year's worth of number-crunching on a supercomputer, Rice University physicist and bioengineer Michael Deem thinks he has the answer: a changing environment may organize the structure of genetic information itself. The research is available online and slated to appear next month in Physical Review Letters.

  5. Computer simulations strongly support new theory of Earth's core
    02-08-2008 · EurekAlert!
    Swedish researchers present in today's Web edition of the journal Science evidence that their theory about the core of the earth is correct. Among other applications, the findings may be of significance for our understanding of the cooling down of the Earth, and of the stability of the Earth's magnetic field.

  6. 'It might be life, Jim...', physicists discover inorganic dust with lifelike qualities
    08-14-2007 · EurekAlert!
    Intriguing new evidence of lifelike structures that form from inorganic substances in space are revealed today in the New Journal of Physics. The findings hint at the possibility that life beyond earth may not necessarily use carbon-based molecules as its building blocks. They also point to a possible new explanation for the origin of life on earth.

  7. Seismic images show dinosaur-killing meteor made bigger splash
    01-23-2008 · EurekAlert!
    The most detailed 3-D seismic images yet of the Chicxulub impact crater may modify a theory explaining the "KT Extinction Event" that wiped out most life on Earth, including the dinosaurs. According to research appearing in Nature Geosciences, the asteroid landed in deeper water than previously assumed and therefore released about 6.5 times more water vapor into the atmosphere, possibly making it deadlier by altering climate and generating acid rain.

    02-18-2007 · EurekAlert!
    As NASA develops its next "flagship" mission to the outer solar system, Jupiter's enigmatic moon Europa should be the target, says Arizona State University professor Ronald Greeley. Although Europa lies five times farther from the Sun than Earth, he notes it may offer a home for life. He is presenting the Europa proposal today (February 18) at the annual meeting of the American Association for the Advancement of Science in San Francisco.

  9. Investigating Life in Extreme Environments report gives hints on facts of life
    07-04-2007 · EurekAlert!
    From the deepest seafloor to the highest mountain, from the hottest region to the cold Antarctic plateau, environments labeled as extreme are numerous on Earth and they present a wide variety of features and characteristics. Investigating life processes in extreme environments not only can provide hints on how life first appeared and survived on Earth (as early earth was an extreme environment) but it can also give indication for the search for life on other planets.

  10. Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers

    A new, complete "tree of life" tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today.
