Researchers expected adsorption to eliminate surface electronic states. Instead, it created one-dimensional states that resemble nanowires.

Cyclic deformations can alter the free-fall motion of a composite body as it moves through curved spacetime.

Prospective international students and visiting scientists are facing greater security scrutiny and long delays before obtaining US visas. Those already in the US are being advised not to leave for fear of not being allowed to return.

As a Canadian mining company appears determined to shut off the pumps that keep South Dakota’s Homestake mine from flooding, the threat of high water is pressuring NSF to choose among three possible underground labs.

Thanks to pork-barrel funding, a small university in New Mexico is building an observatory with scientific, educational, and military applications.

Small-scale experiments sensitive to tiny effects could offer profound insights into what lies beyond the standard model of elementary particles.

Cold, noncrystalline states play an important role in understanding the physics of liquid water. From recent experimental and theoretical investigations, a coherent interpretation of water’s properties is beginning to emerge.

Charged particles surfing on electron density waves in plasmas can experience enormous accelerating gradients.
