Speed limit set for ultrafast electrical switch

Researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have clocked the fastest-possible electrical switching in magnetite, a naturally magnetic mineral. Their results could drive innovations ...

Microscopy reveals 'atomic antenna' behavior in graphene

Atomic-level defects in graphene could be a path forward to smaller and faster electronic devices, according to a study led by researchers at the Department of Energy's Oak Ridge National Laboratory.

New mystery on Mars' forgotten plains

(PhysOrg.com) -- One of the supposedly best understood and least interesting landscapes on Mars is hiding something that could rewrite the planet's history. Or not. In fact, about all that is certain is that decades of assumptions ...

Dual-color lasers could lead to cheap and efficient LED lighting

(Phys.org) —A new semiconductor device capable of emitting two distinct colours has been created by a group of researchers in the US, potentially opening up the possibility of using light emitting diodes (LEDs) universally ...

Smaller than small: Why we measure the space between atoms

We study the movement of incredibly small things. How small is small? Think smaller than "nano." Think smaller than atoms themselves. We measure the infinitesimally small shifts in the positions of atoms to electrical forces. ...

Dark fireworks on the sun

On June 7, 2011, Earth-orbiting satellites detected a flash of X-rays coming from the western edge of the solar disk. Registering only "M" (for medium) on the Richter scale of solar flares, the blast at first appeared to ...
