    While about 93% of American Jews identify with Ashkenazi heritage, Israel and the globe are home to a diverse mix of Sephardic, Mizrahi, and other Jewish communities.

    Yet, media often presents an Ashkenormative image, overshadowing the reality that a significant number of Jews worldwide don't fit into this category.

    In North America, the major Jewish communities are Ashkenazi - with ties to countries like Germany, France, and Eastern Europe - and Sephardic, from Portugal and Spain. But that's just part of the story - globally, there exists a vibrant mosaic of other Jewish cultures, including Mizrahi Jews from the Middle East, Ethiopian Jews, and numerous others.

    Despite their unique languages, cuisines, and even some Jewish customs, all these groups share the core connection of Judaism and are part of a singular, global peoplehood.

    80-year-old mystery in static electricity finally solved
    Historically, contact electrification (CE) was humanity's first and only source of electricity up until around the 18th century, yet its true nature is still elusive. Today it is considered a core component of technologies such as laser printers, LCD production processes, electrostatic painting, and separation of plastics for recycling as well as a major industrial hazard (damage to electronic systems, explosions in coal mines, fires in chemical plants, etc.) due to electrostatic discharges (ESD) accompanying CE. In a vacuum, ESDs of a simple adhesive tape are so powerful that they generate enough X-rays to take an X-ray image of a finger.
