Smolyaninova et al., doi 10.1117/1.AP.2.5.056001 Metamaterials–nanoengineered structures designed for precise control and manipulation of electromagnetic waves–have enabled such innovations as invisibility cloaks and super-resolution microscopes. Using transformation optics, these novel devices operate by manipulating light propagation in “optical spacetime,” which may

A team of scientists from the National Center for Advancing Translational Sciences (NCATS) and Naval Research Laboratory (NRL) in Washington, D.C., has developed a new tool that mimics how SARS-CoV-2 — the virus that causes COVID-19 — infects a cell, information that could potentially speed the search for treatments against the disease. The tool is

However, crystallization in confined spaces, such

An international team of researchers have found a way to refine and reliably produce an unpredictable and hard-to-control material that could impact environmental conservation, energy and consumer electronics. The

Helium-3 is a rare isotope of

As our lives become increasingly intertwined with technology — whether supporting communication while working remotely or streaming our favorite show — so too does our reliance on the data these devices create. Data centers supporting these technology ecosystems produce a significant carbon footprint — and consume 200 terawatt hours of energy each year, greater than
