New use for X-rays: A radar gun for unruly atoms

X-rays have long been used to make pictures of tiny objects, even single atoms. Now a team of scientists has discovered a new use for X-rays at the atomic scale: using them like a radar gun to measure the motion and velocity ...

Kinks and curves at the nanoscale

One of the basic principles of nanotechnology is that when you make things extremely small—one nanometer is about five atoms wide, 100,000 times smaller than the diameter of a human hair—they are going to become more ...
