How do cold ions slide

Things not always run smoothly. It may happen, actually, that when an object slides on another, the advancement may occur through a 'stop and go' series in the characteristic manner which scientists call "stick-slip", a pervasive ...

Jumping to reduce vibrations

A pioneering use of mini-trampolines is allowing engineers to better understand effects of vibrations caused by human movement on floors and small bridges. 

Mercury's magnetic field measured by MESSENGER orbiter

Researchers working with NASA's Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft report the frequent detections of Kelvin-Helmholtz (KH) waves at the edge of the innermost planet's magnetosphere. ...

Caltech researchers create 'sound bullets'

Taking inspiration from a popular executive toy ("Newton's cradle"), researchers at the California Institute of Technology have built a device -- called a nonlinear acoustic lens -- that produces highly focused, high-amplitude ...
