New technique promises tunable laser devices

Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a phenomenon similar to an effect observed in circular galleries, such ...

A new approach to ultrafast light pulses

Two-dimensional materials called molecular aggregates are very effective light emitters that work on a different principle than typical organic light-emitting diodes (OLEDs) or quantum dots. But their potential as components ...

Researchers find new way to manipulate magnetism

In a pioneering effort to control, measure and understand magnetism at the atomic level, researchers working at the National Institute of Standards and Technology (NIST) have discovered a new method for manipulating the nanoscale ...

Blue sky in warm champagne

Popping a bottle of champagne that has been stored at 20 degrees Celsius (something one really ought never do) ejects a fleeting "mini-cloud" colder than ice and blue as the sky, awestruck scientists said Thursday.

Researchers develop new ultra-fast 3D microscope

A new microscope can capture 3-D images of live organisms in real time. It's called the QIs-scope, an innovation from a spinoff of Universidad Carlos III de Madrid (UC3M), 4D Nature. The microscope can be used in biomedical ...

Invisibility cloak closer to becoming a reality

Photonics is a rapidly growing field in which some of the most sci-fi ideas of the not-so-distant past, are taking form. Now EU-funded research is bringing the notion of an invisibility cloak closer by using microscopic structures ...

Physicists predict nonmetallic half-metallicity

A team of researchers of the Russian Academy of Sciences (RAS), in collaboration with a colleague from RIKEN (Institute for Physical and Chemical Research in Japan), has provided theoretical proof of the existence of a new ...

New study looks deeper into atoms than ever before

Scientists are now able to observe a never before seen atomic transformation that may take place in many catalytic reactions, thanks to researchers at Binghamton University and the Brookhaven National Laboratory.

Quantum machine learning

Language acquisition in young children is apparently connected with their ability to detect patterns. In their learning process, they search for patterns in the data set that help them identify and optimize grammar structures ...

Tracing the light inside an LED

The performance of white LEDs can be improved, based on better knowledge of the absorption and scattering of light inside the LED. A new method, developed by the University of Twente in The Netherlands and Philips Lighting, ...

Charmonium surprise at LHCb

Today, the LHCb experiment at CERN presented a measurement of the masses of two particular particles with a precision that is unprecedented at a hadron collider for this type of particles. Until now, the precise study of ...

Driving the universal quantum bus

NIST scientists have achieved a world record in detecting the intensity of an ultra-faint source of light, equaling the capabilities of the deep-space instruments on the Hubble Space Telescope but operating 100 times faster ...
