    Dutch artist M.C. Escher's most famous drawing, "Circle Limit IV (Heaven and Hell)", shows angels and demons in a tessellation that fills a circle without empty spaces. This masterful woodcut inspired an international partnership of researchers including Politecnico di Milano Physics Department to author the cover-story article published in Physical Review Letters. [...]

    The Alpha Magnetic Spectrometer (AMS) collaboration, a large group of researchers from CERN and other institutes worldwide, has recently presented a series of precision measurements of the properties of cosmic Helium isotopes 3He and 4He. These measurements were collected by the AMS, a spectrometer located on the International Space Station (ISS). [...]

    By combining a compressive sensing algorithm with a digital holographic microscope, Prof. Shih-Chi Chen of the Department of Mechanical and Automation Engineering, Faculty of Engineering, The Chinese University of Hong Kong (CUHK) and his research team have developed a high-speed imaging method. The new approach is able to produce two-photon microscopy images of a 3-D sample in one second, which is at a speed three to five times that of the conventional point-scanning method. [...]

    A new advance promises to increase the sensitivity of high-resolution spectrometers that perform chemical analysis using terahertz wavelengths. This higher sensitivity could benefit many applications, such as analysis of the complex gas mixtures found in industrial emissions and detection of biomarkers of disease in the breath of patients. It could also lead to new ways to detect food spoilage through gas detection. [...]

    Researchers at the University of Colorado have recently developed a new technique to measure mechanical motion using simultaneous electromechanical amplification and cooling processes. Their method, presented in a paper published in Physical Review Letters, allowed them to perform a nearly noiseless measurement of the position of a mechanical oscillator, which has so far proved to be difficult using alternative techniques for measuring motion. [...]

    Light is versatile in nature. In other words, it shows different characteristics when traveling through different types of materials. This property has been explored with various technologies, but the way in which light interacts with materials needs to be manipulated to get the desired effect. This is done using special devices called light modulators, which have the ability to modify the properties of light. [...]
