Scientists find elusive waves in sun's corona

08-30-2007 · EurekAlert!

Scientists for the first time have observed elusive oscillations in the sun's corona, known as Alfvén waves. The discovery is expected to give researchers more insight into the fundamental behavior of solar magnetic fields, eventually leading to a fuller understanding of how the sun affects Earth and the solar system.

    12-03-2006 · EurekAlert!
    Scientists have perfected a technique for very accurately measuring and controlling the electromagnetic waves within some of the shortest laser pulses ever made, says new research published today. Being able to fully understand and control these laser pulses represents an important step towards using them to track and manipulate electrons in leading-edge research at the sub-atomic level.

    In a paper published in the Astronomical Journal, Dr. Xiaolei Zhang, of the Naval Research Laboratory, and Dr. Ronald J. Buta, of the University of Alabama, report that they have developed an accurate and widely-applicable method for characterizing density wave features in galaxies. These density waves appear as high-density regions in galaxies in the forms of spirals, bars and rings.

  9. Cat fleas' journey into the vacuum is a 'one-way trip'
    12-17-2007 · EurekAlert!
    Homeowners dogged by household fleas need look no farther than the broom closet to solve their problem. Scientists have determined that vacuuming kills fleas in all stages of their lives, with an average of 96 percent success in adult fleas and 100 percent destruction of younger fleas. In fact, the results were so surprisingly definitive that the lead scientist, an Ohio State University insect specialist, repeated the experiments several times to be sure the findings were correct.
