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 […]

The morphing nozzle in action, 3D printing fiber-filled composite materials with on-demand control of fiber alignment for “4D printing. Credit: University of Maryland Engineers at the University of Maryland (UMD) have created a new shape-changing or “morphing” 3D printing nozzle that was featured as a Frontispiece in the January 5th […]

A thermally modulated battery for mass-market electric vehicles without range anxiety and with unsurpassed safety, low cost, and containing no cobalt, is being developed by a team of Penn State engineers.

Using computer simulations built on reasonable assumptions and conducted under careful control, computational bioscientists can mimic real biological conditions. Starting with the original founding population (ancient phase), they can evolve the population over several thousand generations to develop an intermediate phase, and then evolve that generation another several thousand generations […]

While studying a thin-film material called strontium stannate (SrSnO3), University of Minnesota researchers noticed the surprising formation of checkerboard patterns at the nano scale similar to structures fabricated in costly, multistep processes. Their results show the realistic possibility of designing similar self-assembled structures with wide applications in materials for electronics […]

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 […]

Quantum particles lined up in a lattice form the basis for an error-tolerant quantum processor. Credit: Uni Innsbruck/Harald Ritsch Even computers can miscalculate. Already small disturbances change stored information and corrupt results. That is why computers use methods to continuously correct such errors. In quantum computers, the vulnerability to errors […]

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, […]
