  "summary": "Scientists have found a new way to create a controlled beam of muonium, an exotic atom containing a heavier cousin of the electron. The advance could allow researchers to test for the first time whether gravity acts on second-generation particles exactly as Einstein’s theory predicts. Any unexpected difference would be a major surprise and could potentially point toward new physics, including a…",
