'Resonance' raman spectroscopy with 1-nanometer resolution

Tip-enhanced Raman spectroscopy resolved "resonance" Raman scattering with 1-nm resolution in ultrathin zinc oxide films epitaxially grown on a single-crystal silver surface. Tip-enhanced "resonance" Raman scattering can ...

Recovering color images from scattered light

Engineers at Duke University have developed a method for extracting a color image from a single exposure of light scattered through a mostly opaque material. The technique has applications in a wide range of fields from healthcare ...

Scientists film rotating carbonyl sulphide molecules

Scientists have used precisely tuned pulses of laser light to film the ultrafast rotation of a molecule. The resulting "molecular movie" tracks one and a half revolutions of carbonyl sulphide (OCS)—a rod-shaped molecule ...

Spiraling filaments feed young galaxies

Galaxies grow by accumulating gas from their surroundings and converting it to stars, but the details of this process have remained murky. New observations, made using the Keck Cosmic Web Imager (KCWI) at the W. M. Keck Observatory ...

Mapping our global human footprint

The number of people flocking to cities in search of employment and better prospects is growing at an unprecedented rate. By 2050, the global population is estimated to reach nine billion, 70% of which will be living in urban ...

Direct atom-resolved imaging of magnetic materials

In conventional electron microscopes, performing atomic-resolution observations of magnetic materials is particularly difficult because high magnetic fields are inevitably exerted on samples inside the magnetic objective ...
