Seeing nanoscale details in mammalian cells

In 2014, W. E. Moerner, the Harry S. Mosher Professor of Chemistry at Stanford University, won the Nobel Prize in chemistry for co-developing a way of imaging shapes inside cells at very high resolution, called super-resolution ...

Researchers turn light upside down

Researchers from CIC nanoGUNE (San Sebastian, Spain) and collaborators have reported in Science the development of a so-called hyperbolic metasurface on which light propagates with completely reshaped wafefronts. This scientific ...

Electro-mechano-optical NMR detection

An international research project led by Kazuyuki Takeda of Kyoto University and Koji Usami of the University of Tokyo has developed a new method of light detection for nuclear magnetic resonance (NMR) by up-converting NMR ...

Speed of light drops to zero at 'exceptional points'

Light, which travels at a speed of 300,000 km/sec in a vacuum, can be slowed down and even stopped completely by methods that involve trapping the light inside crystals or ultracold clouds of atoms. Now in a new study, researchers ...

A magnetic brake on proton acceleration

Shine a powerful laser onto a solid, and you get a beam of high-energy protons. Far from being a curiosity, this phenomenon has important applications, such as in neutron-generation research. Theoretically, the more intense ...

New marking technique could halt counterfeit goods

Researchers at the University of Copenhagen have developed the world's most secure marking system for combating pirated goods, including pirated pharmaceuticals, food, designer merchandise and artwork. The system could be ...

Scientists achieve high power with new smaller laser

An international team of scientists has produced the first high-powered, randomly polarised laser beam with a "Q switch" laser, which typically emits pulses of light so brief that they're measured in nanoseconds. Lasers are ...

Advances in lasers get to the long and short of it

Since lasers were first developed, the demand for more adaptable lasers has only increased. Chiral nematic liquid crystals (CLCs) are an emerging class of lasing devices that are poised to shape how lasers are used in the ...

A new model of frequency combs in optical microresonators

A team from the Faculty of Physics of the Lomonosov Moscow State University, together with scientists from the Russian Quantum Center, have developed a new mathematical model that describes the process of soliton occurrence ...

Researchers develop transportable optical atomic clock

Atomic clocks are no longer based on a microwave transition in cesium, instead operating with other atoms that are excited using optical frequencies. Some of these new clocks are portable. At its QUEST Institute, PTB is currently ...

Scientists create high-speed coding system

Scientists of the National Research Nuclear University MEPhI (Russia) have proposed a scheme for optical encoding of information based on the formation of wave fronts, and which works with spatially incoherent illumination. ...
