Manipulating Nanoscale light in nanocavity of scanning tunneling microscope junctions

Manipulating nanoscale light in scanning tunneling microscope junctions is attained by nanofabrication of gold tips using a focused ion beam technique. Researchers at Fritz-Haber Institute, Berlin, Germany, demonstrated that a spectrum of “nanolight” in a nanoscale plasmonic junction can be modulated with plasmonic Fabry–Pérot tips. Precise control of nanolight is of key relevance to nanoscale imaging and spectroscopy to investigate […]

Created new artificial rhodopsin protein – Expecting elucidation of neural networks in the deep brain

Rhodopsins are protein families that work with light energy, transmit visual information in the body of animals and transports ions in the cells of micro-organisms by light. In recent years, application of rhodopsin for optogenetics technology into studies of brain neural circuits with light and medical treatments including visual reproduction both gains high level of public interests. Figure 1: Left: […]

Organic laser diodes move from dream to reality

Researchers from Japan have demonstrated that a long-elusive kind of laser diode based on organic semiconductors is indeed possible, paving the way for the further expansion of lasers in applications such as biosensing, displays, healthcare, and optical communications. Long considered a holy grail in the area of light-emitting devices, organic laser diodes use carbon-based organic materials to emit light instead […]

New cable-free brain imaging method may take social neuroscience to the next level

Existing electrophysiological and fluorescence-based brain imaging techniques in mice are generally invasive, require head fixes or cables, and are not suitable for long-term recordings. While there have been recent advances in imaging methods in freely moving animals, these are major limitations for researchers that are interested in the brain correlates of social behaviors. Researchers at Osaka University have developed a […]

Development of a displacement sensor to measure gravity of smallest source mass ever

One of the most unknown phenomena in modern physics is gravity. Its measurement and laws remain somewhat of an enigma. Researchers at Tohoku University have revealed important information about a new aspect of the nature of gravity by probing the smallest mass-scale. Professor Nobuyuki Matsumoto has led a team of researchers to develop a gravity sensor based on monitoring the […]
