  1. Paleontology

    Allosaurus as a Jurassic headbanger

    The skull of the carnivorous dinosaur Allosaurus fragilis can resist levels of stress much higher than those expected from chewing, which may provide insight into the animal's method of attacking its prey.

  2. Paleontology

    Calling all orthodontists. . .

    Researchers have unearthed fossils of a theropod dinosaur whose front teeth grew almost directly forward, which sets it apart from all other related species.

  3. Paleontology

    A Makeover for an Old Friend

    Time and technology revamp a dinosaur classic.

  4. Paleontology

    Early Biped Fossil Pops Up in Europe

    A newly described, nearly complete 290-million-year-old fossil of an ancient reptile pushes back the evidence for terrestrial bipedalism by 60 million years.

  5. Paleontology

    Listening to fish for extinction clues

    Tiny fossils from fish that survived worldwide extinctions about 34 million years ago may reveal that cooler winters caused the die-off.

  6. Earth

    A slump or a slide? Density decides

    Using a full-scale simulator, researchers showed that just a small difference in soil density determines whether a landslide becomes a fast-moving killer or merely one that slowly slumps downhill.

  7. Earth

    Flaws make it a geologist’s best friend

    By analyzing some of a diamond's trapped impurities, researchers were able to measure remnants of the gargantuan pressure that produced the gem.

  8. Physics

    Solid-state insights yield physics Nobel

    The 2000 Nobel Prize in Physics went to three scientists and inventors whose work laid the foundation of modern information technology, particularly through their invention of rapid transistors, laser diodes, and integrated circuits.

  9. Earth

    Two microbes team up to munch methane

    Aggregates of two different microorganisms in methane-bearing ocean sediments collected off the Oregon coast appear to collaborate to consume methane despite a lack of oxygen.

  10. Earth

    The Making of a Grand Canyon

    Carving this beloved hole in the ground may not have been such a long-term project.

  11. Earth

    Model offers grounds for midwestern quakes

    A new computer model may help explain how earthquakes can happen at fault zones located far from the edges of a tectonic plate.

  12. Earth

    High-Flying Science, with Strings Attached

    In the hands of scientists, kites do serious data gathering.
