Researchers fabricated a material that generates an electric field due to a stretched atomic structure, and they modified its properties by changing its growth conditions. Similar materials may be useful in nanotechnology.

Experiments suggest that the celebrated “boson peak”—a low-frequency vibrational feature characteristic of amorphous materials—may be related to a well-known phonon singularity in ordered crystalline materials.
Properties of vibrations in a pillar in a 1400-year-old Sicilian cathedral correlate with those of very small, nearby earthquakes, suggesting new ways of monitoring the gradual damage that such quakes can inflict on old buildings.
