[Report] Rewritable artificial magnetic charge ice

Artificial ices enable the study of geometrical frustration by design and through direct observation. However, it has proven difficult to achieve tailored long-range ordering of their diverse configurations, limiting both fundamental and applied research directions. We designed an artificial spin structure that produces a magnetic charge ice with tunable long-range ordering of eight different configurations. We also developed a technique to precisely manipulate the local magnetic charge states and demonstrate write-read-erase multifunctionality at room temperature. This globally reconfigurable and locally writable magnetic charge ice could provide a setting for designing magnetic monopole defects, tailoring magnonics, and controlling the properties of other two-dimensional materials.

    Random number generators go public

    On 10 July, researchers in Chile will unveil an online public random number service. Later in July, the U.S. National Institute of Standards and Technology (NIST) will launch its Randomness Beacon as a permanent service, upgrading a pilot program that began in 2013. Brazil, too, is planning ... more

    When the cure kills—CBD limits biodiversity research

    The Convention on Biological Diversity (CBD) commits its 196 nation parties to conserve biological diversity, use its components sustainably, and share fairly and equitably the benefits from the utilization of genetic resources. The last of these objectives was further codified in the Conve ... more

    See-through solar cells could power offices

    Solar windows turn some of the light shining through into electricity. They've been on the market for years. But many of these windows absorb some visible light, leaving them with a reddish or brownish hue, a trait frowned on by architects. Now, new versions are on the way that absorb invis ... more

    It's Not an Illusion

    Researchers have developed a compound that can transform near-infrared light into broadband white-light, offering a cheap, efficient means to produce visible light. The emitted light is also exceedingly directional, a desirable quality for devices like microscopes that require high spatial ... more
