Dark side of the moon revealed: Lunar Reconnaissance Orbiter's LAMP reveals lunar surface features Posted: 13 Jan 2012 06:06 PM PST New maps produced by the Lyman Alpha Mapping Project aboard NASA's Lunar Reconnaissance Orbiter reveal features at the moon's northern and southern poles in regions that lie in perpetual darkness. LAMP uses a novel method to peer into these so-called permanently shadowed regions, making visible the invisible.

Tiny transmitter sets frequency record: Revolutionary terahertz transmitter developed Posted: 13 Jan 2012 06:02 PM PST A terahertz transmitter has generated the highest frequency ever attained by a microelectronic device. The innovative device is also minuscule and operates at room temperature, which could lead to it paving the way for new applications in, e.g., nondestructive testing or medical diagnostics.

Charges going astray: New transfer paths for electrons discovered Posted: 13 Jan 2012 05:59 PM PST In the development of materials for energy production and distribution, knowledge of molecular processes in electrical charge transfer is fundamental. Scientists have once more discovered that nature provides interesting templates for long-range electron transfer.

Give support to repulsion, and you'll see attraction. We know why Posted: 13 Jan 2012 05:54 PM PST When two objects repel each other under the action of one force, we usually expect that addition of another force, also repulsive one, will accelerate separation. This intuitive view is, however, not always true. Researchers have now managed to explain surprising results of experiments with mixtures, where two repulsive interactions have lead to a strong attraction.

Slippery when stacked: Theorists quantify the friction of graphene Posted: 11 Jan 2012 10:40 AM PST Similar to the way pavement, softened by a hot sun, will slow down a car, graphene slows down an object sliding across its surface. But stack the sheets and graphene gets more slippery, say theorists who developed new software to quantify the material's friction.
