Biomedical optics play crucial roles across medicine
Medical physicist, inventor and entrepreneur Brian Pogue is our podcast guest The post Biomedical optics play crucial roles across medicine appeared first on Ph...
These “smart” crystals bend and snap back when hit with light
Perovskite crystals can dramatically and reversibly change shape when hit with light, a behavior not seen in conventional semiconductors. This effect, called ph...
Counting photons could redefine the future of CT imaging
Advanced photon-counting detectors could transform clinical imaging The post Counting photons could redefine the future of CT imaging appeared first on Physics...
Photons light the way
Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales....
Helical liquid crystals can flip light's chirality under ultralow electric fields
The direction in which the electromagnetic field of circularly polarized light rotates can be easily reversed by applying a voltage, RIKEN researchers have demo...
Hidden features in X-rays could radically change how we measure and understand them
Hidden features uncovered in X-ray signals are set to overturn a key scientific theory and fundamentally change how X-rays are interpreted across fields of phys...
Compact flat-lens system can generate nondiffracting bottle beams
Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light t...
Racetrack-shaped lasers developed for bright, stable frequency combs
A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Technical...
Scientists unlock a powerful new way to turn sunlight into fuel
Scientists have developed a powerful new computational method that could accelerate the search for next-generation materials capable of turning sunlight into us...
Scientists just found a way to store massive data using light in 3 dimensions
A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a mat...
