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 ...

Researchers make thinnest plates that can be picked up by hand

Scientists and engineers are engaged in a global race to make new materials that are as thin, light and strong as possible. These properties can be achieved by designing materials at the atomic level, but they are only useful ...

New sensor sends electronic signal when estrogen is detected

Estrogen is a tiny molecule, but it can have big effects on humans and other animals. Estrogen is one of the main hormones that regulates the female reproductive system - it can be monitored to track human fertility and is ...

Shape-shifting gels get smarter

Gels are useful: we shave, brush our teeth, and fix our hair with them; in the form of soft contact lenses they can even improve our eyesight.

Study explores nanoscale structure of thin films

The world's newest and brightest synchrotron light source—the National Synchrotron Light Source II (NSLS-II) at the U.S. Department of Energy's Brookhaven National Laboratory—has produced one of the first publications ...
