Health news today ranges from the practical to the poignant. U.S. officials confirmed a norovirus outbreak aboard Princess Cruises’ Ruby Princess, with more than 120 passengers and crew sickened during a 20-day voyage from San Francisco to Canada and Alaska, a reminder of how quickly infection can spread in close quarters. In Tasmania, authorities are issuing a different kind of public-health appeal, asking people to keep their distance from Neil, a one-tonne elephant seal whose social-media fame is drawing risky attention as he blocks roads and disrupts coastal neighborhoods. The day also brought a stark justice story from Cardiff, where a teenager received a lengthy prison sentence for murdering a mother of three with a car. And in the world of medical innovation, Sky Labs used a clinical trials summit in Basel to promote its digital biomarker platform, underscoring the growing role of data-driven tools in global drug development.
