Grand Canyon may be as old as dinosaurs, says new study
New geological evidence indicates the Grand Canyon may be so old that dinosaurs once lumbered along its rim, according to a study by researchers from the University of Colorado at Boulder and the California Institute of Technology. (2008-04-11)
Mercury's shifting, rolling past
Patterns of scalloped-edged cliffs or lobate scarps on Mercury's surface are thrust faults that are consistent with the planet shrinking and cooling with time. However, compression occurred in the planet's early history and Mariner 10 images revealed decades ago that lobate scarps are among the youngest' features on Mercury. Why don't we find more evidence of older compressive features? (2008-03-18)
10 questions shaping 21st-century earth science identified
Ten questions driving the geological and planetary sciences were identified today in a new report by the National Research Council. Aimed at reflecting the major scientific issues facing earth science at the start of the 21st century, the questions represent where the field stands, how it arrived at this point, and where it may be headed. (2008-03-13)
New Research Suggests Biofuel Blending is Often Inaccurate
While sampling blended biodiesel fuels purchased from small-scale retailers, researchers at the Woods Hole Oceanographic Institution found that many of the blends do not contain the advertised amount of biofuel. (2008-02-28)
2 oxygenation events in ancient oceans sparked spread of complex life
The rise of oxygen and the oxidation of deep oceans between 635 and 551 million years ago may have had an impact on the increase and spread of the earliest complex life, including animals. (2008-02-26)
Hot springs microbes hold key to dating sedimentary rocks, researchers say
Scientists studying microbial communities and the growth of sedimentary rock at Mammoth Hot Springs in Yellowstone National Park have made a surprising discovery about the geological record of life and the environment. (2008-01-23)
Brown Planetary Geologists Lend Expertise to Mercury Mission
What lies on the uncharted side of mysterious Mercury, the smallest planet in the solar system? Brown University students, led by planetary geologist James Head, will study never-before-seen images of Mercury when a NASA spacecraft makes the first visit to Mercury in nearly 33 years. (2008-01-14)
Arsenic contamination lacks one-size-fits-all remedy
Though a worldwide problem, arsenic contamination of drinking water does not have a universal solution. (2007-12-11)
Helium isotopes point to the best sources of geothermal energy
With fossil fuel sources depleting and global warming on the rise, exploring alternative means of power for humans is a necessary reality. (2007-12-03)
Uranium isotope ratios are not invariant, researchers show
For years, the ratio of uranium's two long-lived isotopes, U-235 and U-238, has been considered invariant, despite measurements made in the mid-1970s that hinted otherwise. (2007-10-24)
