    November 6, 2019 An engineer proposes a new model for the way humans localize sounds. by Tracey Regan, New Jersey Institute of Technology Credit: New Jersey Institute of TechnologyOne of the enduring puzzles of hearing loss is the decline in a person's ability to determine where a sound originates, a key survival faculty that allows animals—from lizards to humans—to pinpoint the location of danger, prey and group members. In modern times, finding a lost cell phone by using th...

    Illustration of the exciton of TiO2 interacting with a propagating coherent acoustic wave. Credit: Adriel Dominguez (Max Planck Institute, Hamburg)Physicists from Switzerland, Germany, and France have found that large-amplitude acoustic waves, launched by ultrashort laser pulses, can dynamically manipulate the optical response of semiconductors..

    IMAGE:Illustration of the exciton of TiO2 interacting with a propagating coherent acoustic wave. Image credit:Adriel Dominguez (Max Planck Institute, Hamburg) One of the main challenges in materials science research is to achieve high tunability of the optical properties of semiconductors at room temperature. These properties are governed by "excitons", which are bound pairs of negative electrons and positive holes in a semiconductor. Excitons have become increasingly important...

November 19, 2019 Earth's magnetic song recorded for the first time during a solar storm. by European Space Agency In this image, Earth is the dot to the left of the image and the large arc around it is our planet’s magnetic bow shock. The swirling pattern to the right is the foreshock region where the solar wind breaks into waves as it encounters reflected particles from the bow shoc...
