  1. Paleontology

    Reptile remains fill in fossil record

    The fossil remains of a sphenodontian, an ancient, lizardlike reptile, are helping fill a 120-million-year-old gap between this creature's ancestors and today's tuatara, sole survivors of the once prominent group.

  2. Health & Medicine

    Do Arctic diets protect prostates?

    Marine diets appear to explain why the incidence of prostate cancer among Inuit men is lower than that of males anywhere else in the world.

  3. Planetary Science

    To the moon, European style

    The European Space Agency launched its first lunar mission, which is scheduled to reach the moon in 2005 and will search for water that may lie in the moon's permanently shadowed craters.

  4. Health & Medicine

    Danger, danger, cry injured cells

    Damaged cells may release uric acid to rouse the immune system.

  5. Earth

    Smog chemicals found even in rural western plains

    Analyses of the atmosphere over the south-central United States show that gases emitted from the region's oil and natural gas industries contribute to air pollution—even over remote Kansas cornfields—that can surpass the noxious mix found in urban areas.

    New Quarktet: Subatomic oddity hints at pentaparticle family

    Evidence for the second particle ever found to include five of the fundamental building blocks known as quarks and antiquarks suggests that a whole family of such so-called pentaquarks exists.

  12. A Shot at Pain Prevention: Nerve-healing protein relieves rats’ misery

    A chemical that spurs growth of nerve cells during fetal development may provide a new way to treat severe chronic pain that results from nerve damage.
