Gravity surveys using a mobile atom interferometer

Mobile gravimetry is an important technique in metrology, navigation, geodesy and geophysics. Although atomic gravimeters are presently used for accuracy, they are constrained by instrumental fragility and complexity. In ...

Study reveals new patterns of key ocean nutrient

The important nutrient phosphate may be less abundant in the global ocean than previously thought, according to a new paper in Science Advances. The researchers compiled data collected using highly sensitive techniques that ...

'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 ...

Lighting up proteins with Immuno-SABER

To better understand how tissues and organs develop, fail to function, and regenerate over time, researchers would like to visualize their constituent cells' repertoires of molecules within 3-D space. Ambitious efforts like ...

Manufacture of light-activated proteins

A new strategy for designing light-sensitive proteins has been developed by researchers at Ruhr-Universität Bochum (RUB). Such proteins, also known as optogenetic tools, can be switched on and off through light impulses, ...

Quantum light sources pave the way for optical circuits

An international team headed up by Alexander Holleitner and Jonathan Finley, physicists at the Technical University of Munich (TUM), has succeeded in placing light sources in atomically thin material layers with an accuracy ...
