ANIMATION The odd, wavy pattern that results from viewing certain phone or computer screens through polarized glasses has led researchers to take a step toward thinner, lighter-weight lenses. Called moiré, the pattern is made by laying one material with opaque and translucent parts at an angle over another material of […]

UWA’s rooftop observatory. Credit: ICRAR Scientists from the International Centre for Radio Astronomy Research (ICRAR) and The University of Western Australia (UWA) have set a world record for the most stable transmission of a laser signal through the atmosphere. In a study published today in the journal Nature Communications, Australian […]

3-D image reconstruction of a sample of irradiated fuel, showing the three thresholded uranium phases co-existing with pores. Credit: Maria Okuniewski / Purdue University In a feat requiring perseverance, world-leading technology, and no small amount of caution, scientists have used intense X-rays to inspect irradiated nuclear fuel. The imaging, led […]

Concept for Exawatt-class lasers. Credit: Osaka University Researchers from Osaka University propose a concept for next-generation ultra-intense lasers, possibly increasing the current record from 10 Petawatts to 500 Petawatts. Ultra-intense lasers with ultra-short pulses and ultra-high energies are powerful tools for exploring unknowns in physics, cosmology, material science, etc. With […]

Schematic representation of a processor for matrix multiplications which runs on light. Credit: University of Oxford The exponential growth of data traffic in our digital age poses some real challenges on processing power. And with the advent of machine learning and AI in, for example, self-driving vehicles and speech recognition, […]

Researchers at the University of Tokyo have found a way to enhance the sensitivity of existing quantitative phase imaging so that all structures inside living cells can be seen simultaneously, from tiny particles to large structures. This artistic representation of the technique shows pulses of sculpted light (green, top) traveling […]

UV fluorescence examination. Credit: The authors Analyses of the materials in the scrolls helps put the object into a historical context and guides conservators in future restoration efforts. A picture may be worth a thousand words, but capturing multiple images of an artifact across the electromagnetic spectrum can tell a […]

This illustration of a nanoscale node created by the lab of Nick Vamivakas, professor of quantum optics and quantum physics, shows a closeup of one of an array pillars, each a mere 120 nanometers high. Each pillar serves as a location marker for a quantum state that can interact with […]

Illinois researchers developed a spherical lens that allows light coming into the lens from any direction to be focused into a very small spot on the surface of the lens exactly opposite the input direction. This is the first time such a lens has been made for visible light. Credit: […]
