Chip-scale spectrometry using a photonic molecule

Chip-scale miniaturization of spectrometers allows rapid detection of spectral information in portable devices, opening up new applications. However, integrated spectrometers typically suffer from a trade-off between spectral ...

New polymers show interaction with cells

A new development in biomedical research could open the door to a variety of new applications: Scientists at the University of Bayreuth have found that certain polymers, called polyanions, can penetrate cells in a unique ...

Using the power of symmetry for new quantum technologies

By taking advantage of nature's own inherent symmetry, researchers at Chalmers University of Technology in Sweden have found a way to control and communicate with the dark state of atoms. This finding opens another door toward ...

Scientists develop novel 'shapeshifting' liquid crystal

Physicists at Case Western Reserve University and Tufts University say they've changed the shape of a flat liquid crystal surface without applying any local stimulus—essentially remotely altering its physical appearance ...

Single laser produces high-power dual comb femtosecond pulses

Researchers have developed a new approach that uses a single laser cavity to create two high-power optical frequency combs emitting high-power femtosecond pulses. The new development paves the way for portable dual-comb light ...

Indian capital launches campaign to curb toxic air pollution

Authorities in New Delhi launched an anti-pollution campaign on Monday in an attempt to curb air pollution levels ahead of winter, when the capital is regularly covered in toxic haze, and warned that filthy air could make ...
