It was another big week for physics as a team of researchers led by Brown University's Vesna Mitrovic found new evidence for an unusual superconducting state—the results of fifty years of research. Also, a team of cosmologists working on project POLARBEAR detected curls in the oldest light in the universe—it represents the most precise and sensitive measurements of the microwave background to date. And a team of researchers at Shanghai University found a unique 1-D metasurface that acts as a polarized beam splitter, allowing a novel form of holography. It's different from 2-D and 3-D methods and offers the possibility of better security when used in anti-counterfeiting holographs.
